2023-02-13 Classification of Steel Pipe Elbows Classification of Steel Pipe Elbows Steel pipe elbows can be classified through following various parameters, Direction Angle Length and Radius Connection with Pipe Material of Construction Types of Elbows based on Direction Angle According to fluid flow direction of the pipes, elbows can be divided into different degrees, such as 45 degree, 90 degree, 180 degree, which are most common elbows. Also there are 60 degree and 120 degree elbows for some special pipelines. This degree is just an representation of the angle by which the fluid flow is going to change after flowing through the said elbow.

2023-07-03 Carbon Steel Pipe Elbow Fittings Pipe Elbow Fittings Pipe elbow fittings is a very important pipe fitting. When we talk about a pipe elbow, it means a length of pipe with a sharp bend in it. Pipe elbows are fitting accessories which are used widely in various industrial sectors in pipe fitting. A pipe elbow is frequently used in pressurized applications and are available in various shapes and sizes for use in different applications. A pipe elbow is a fitting installed between two lengths of pipe or tube allowing a change of direction, usually in the 90° or 45° direction. Materials Used for Pipe Elbow Fittings Various materials are used in the making of pipe elbows like as follows: Rubber Plastic Iron Steel Copper Stainless steel Aluminum Cast iron Ductile iron etc.

2023-04-04 YPCO Product Introduction:Reducing Tee Reducing Tee Reducing tee is another type of pipe tee used in pipe and tube fittings. Pipe Tees are available two popular forms-have all outlets of the same size or they can be reducing tees in which they are with a combination of different outlet sizes. Reducing tee, like all pipe tees, is in the shape of T with two ends of equal size and the third one slightly smaller. In other words, reducing tee is a type of pipe fitting in which the branch port size is smaller than the ports of the run. This type of pipe fitting can also consider size reduction from one of the run ports to the other. For different applications in various industries, the reducing tees are available in many various combinations of sizes and configurations. Apart from the standard sizes, other unusual combinations of size can also be attained using component parts of tees, reducing tee and reducers. Materials used: Aluminum Bronze Brass Carbon Ceramic Clay Rubber Fiberglass Cast iron Lead Plasti

2023-04-24 YPCO Product Introduction:Pipe Reducer Pipe Reducer Pipe reducer are tube fittings that are widely used in a number of industries in order to providing greatest connection flexibility in connecting fractional tubes in various installations. Pipe reducer is a kind of pipe fitting that joins two pipes of different diameter. The pipe reducers are available in a range of materials depending on the end use of the products and these fittings are manufactured in inch and metric size. Pipereducers are special type of tube fittings that are commonly used in the demanding environments of chemical and power plants. They provide a highly reliable, sturdy and tight integral line system and these type of pipe fittings remain unaffected by shock, vibration or thermal distortion. These pipe fittings are very easy to install and they resist leakage due to thermal or pressure cycling. These reducers are sometimes chrome or nickel coated to prevent corrosion and increase the life of the product. Applications of Pipe Reducer: Hydraulic system Pneumatic system Pharmaceutical fittings Air brake fittings Gas fittings Refrigerant fittings

2023-05-08 Socket Weld Flanges:A Popular Type of Flange Socket Welding Flanges Socket Welding Flange, a popular type of pipe flange, was initially developed for use on small-sized high- pressure piping. The fabrication of this type of flange is similar to that of a Slip On Flange. However, the internal pocket of a socket welding flange allows for a smooth bore and better fluid flow. When provided with an internal weld, the static strength of this flange is equal to slip-on flange, but the fatigue strength is 50% greater than double welding slip-on flanges. In our company, Steel Flange can be supplied, including carbon steel and stainless steel Socket Welding Flanges. Smooth bore conditions in such a flange can easily be attained without having to bevel the flange face and, after welding, to reface the socket weld flange as would be required with slip-on flanges. For this reason, the internally welded flange is popular in chemical process piping. Materials used: Alloy steel Carbon steel Stainless steel Cast iron Rubber

2023-06-15 YPCO Product Introduction:Steel Pipe Fittings Steel Pipe Fittings Steel has been used for making pipe and pipe fittings since years for its durability and strength. Moreover, steel offers high resistance to heat. This property also adds to the popularity of steel for making pipes and pipe fittings. Steel pipes and pipe fittings are widely used in houses and industrial purposes for carrying water, flammable gases, fire sprinkler systems, etc. As steel pipes tend to rust, they are often mixed with other materials to add to its durability and make it rust resistant. Varieties of Steel: Pipe fittings are made of various types of steel like: Galvanized Steel: In order to protect steel from rust and corrosion, steel is coated in layers of zinc through a chemical process. Galvanized steel offers resistance to rust and corrosion and is highly preferred for making pipe fittings and pipe. Galvanized steel also increase the longevity of pipe fittings. Fittings made of galvanized steel are available in standard sizes ranging from 8mm to 150mm. Galvanized pipe fittings are usually manufactured from seamless tube, forgings or rolled bar or welded tube following some specific standards. Galvanized steel pipe fittings

2023-06-25 YPCO Product Introduction:Pipe Flanges Pipe Flanges Pipe Flanges are widely used as a popular category of pipe fittings. A flange is used to mechanically connect two pipes together. It can also be used to mechanically connect a pipe to a tee, valve, choke or any other piece of equipment. Flanges are available in round, square, and rectangular shapes. In some cases, flanges are usually in the shape of a ring or a plate to form a rim at the end of a pipe when fastened to the pipe. This is an example of closet flange. A flange can also be a plate for covering or closing the end of a pipe. This is a blind flange. Thus, flanges are considered to be projecting or internal components which are used to support mechanical parts. They are like rims which are used to strengthen the mechanical part or they are a means of attaching that part to another part or surface Flange connection is to fix two pipes, pipe fittings or equipment on a flange respectively, add flange gasket between the two flanges, and fasten them together with bolts

2023-02-17 YPCO Standards Introduction: ASME standards (U.S.) Pipe flanges that are made to standards called out byASME B16.5 or ASME B16.47, and MSS SP-44. They are typically made from forged materials and have machined surfaces. ASME B16.5 refers to nominal pipe sizes (NPS) from 1⁄2" to 24". B16.47 covers NPSs from 26" to 60". Each specification further delineates flanges into pressure classes: 150, 300, 400, 600, 900, 1500 and 2500 for B16.5, and B16.47 delineates its flanges into pressure classes 75, 150, 300, 400, 600, 900. However these classes do not correspond to maximum pressures in psi. Instead, the maximum pressure depends on the material of the flange and the temperature. For example, the maximum pressure for a Class 150 flange is 285 psi, and for a Class 300 flange it is 740 psi (both are for ASTM a105 carbon steel and temperatures below 100°F). The gasket type and bolt type are generally specified by the standard(s); however, sometimes the standards refer to the ASME Boiler and Pressure Vessel Code (B&PVC) for details (see ASME Code Section VIII Division 1 – Appendix 2). These flanges are recognized by ASME Pipe Codes such as ASME B31.1 Power Piping, and ASME B31.3 Process Piping. Materials for flanges are usually under ASME designation: SA-105 (Specification for Carbon Steel Forgings for Piping Applications), SA-266 (Specification for Carbon Steel Forgings for Pressure Vessel Components), or SA-182 (Specification for Forged or Rolled Alloy-Steel Pipe Flanges, F

2023-02-22 Features of WN Flange and SO Flange Neck butt welding flange refers to a kind of flange with a cone neck and butt welding with the cylinder or pipe, which belongs to the integrated flange. Slip on pipe flanges are typically provided with a raised or flat face. When a raised face is necessary for slip on pipe flanges, the standard height is 1/16" for slip on pipe flanges under 400#. For slip on pipe flanges of 400# and up, the standard slip on pipe flange raised face height is 1/4". The full name of neck flat welded flange is neck flat welded steel pipe flange, which can extend the steel pipe and pipe fittings into the flange and connect with the equipment or pipe through the fillet weld. Weld Neck Flanges are flanges with the wall thickness of the flange having the same dimensions of the matching pipe, the lighter the pipe is, the larger the bore, conversely, the heavier the pipe, the smaller the bore, they are normally used for high pressure, cold or hot temperature. Except this two kinds of flanges, our company also has other flanges, includes Blind Flange, Lap Joint Flange, Threaded Flange, etc. Each kind of falanges are of high quality.

2023-02-20 Steel Flanges used in Butt Welding Butt welding flange is also called high neck flange, it is different from flat welding flange in that there is a long and inclined high neck from the flange and pipe welding to the flange, the wall thickness of this section of high neck gradually transition to the wall thickness along the height direction, improve the stress discontinuity, thus increasing the strength of the flange. Butt welding flange is mainly used in harsh working conditions, such as pipe thermal expansion or other loads and the flange is subjected to large stress or stress changes repeatedly occasions, pressure, temperature fluctuations of the pipeline or high temperature, high pressure and sub-zero low temperature pipeline. Butt welding flange is not easy to deformation, seal well, widely used, nominal pressure PN1.0MPa~PN25.0MPa. Butt welding flange according to the type of sealing surface can be divided into: plane butt welding flange, protruded face welding flange, concave and convex face welding flange, tenon face welding flange, ring joint face butt welding flange. Youlong Pipe Fitting can supply you with high quality products, including ECC Reducer, Reducing Tee,

2023-02-20 Flat Welding Flange for Pipe Connection Flat Welding Flange Flat welding flange, plate flat welding flange, flat flange is a general term, sometimes for convenience is also called flat. It is different from Butt Welding Flange, which includes Welding Neck Flange and Slip On Flange. In chemical industry flange, mechanical flange, Japanese standard flange, German standard flange, American standard flange, Marine flange and other standards have this. In the domestic industry on the general pipeline consumption is the most, the pressure from 0.25MPa to 4.0MPa. Steel Flat welded flange, as the name suggests, is a Steel Flange without a neck. Insert the pipe directly into the flange for welding. In general, the inner diameter of the small-caliber flange is slightly larger than the pipe by 1-1.5mm to leave such a margin, in order to make appropriate adjustments in the installation process. The large flange should be kept more, because the flange is of large caliber, so it is inconvenient to keep it small. The sealing surface of flat welding flange is generally divided into two kinds: one is called FF surface, that is, the full plane flange, so to say, the flange is like a disk, there is a hole in the middle and then play the corresponding bolt hole around, this is called the full

2023-02-20 Steel Tee Pipe Fittings in Youlong:Butt Weld Tee and Socket Weld Tee 1.Butt Weld Tee There are many kinds of Steel Tee. It can be devide into Equal Tee and Reducing Tee. Butt weld tee is widely used in petroleum, aerospace pharmacy, chemical industry, metallurgy, electric power, military industry, engineering support and other industrial pipelines. Ends in plain or beveled, connected by butt welding process. It can withstand higher pressure than other types. The size of butt weld tee should be specified in pipe NPS (DN) and thickness in schedule, where the socket weld tee or thread tee thickness should be specified in the pressure level. Butt weld tee is divided into seamless cold-drawn tee and seam welding tee in the production process. 2.Socket Weld Tee

2023-02-06 Pipe Flanges Introduction and Information Piping components can be bolted together between flanges. Flanges are used to connect pipes with each other, to valves, to fittings, and to specialty items such as strainers and pressure vessels. A cover plate can be connected to create a "Blind Flange". Flanges are joined by bolting, and sealing is often completed with the use of gaskets or other methods. Mechanical means to mitigate effects of leaks, like spray guards or specific spray flanges, may be included. Industries where flammable, volatile, toxic or corrosive substances are being processed have greater need of special protection at flanged connections. Flange guards can provide that added level of protection to ensure safety. There are many different flange standards to be found worldwide. To allow easy functionality and interchangeability, these are designed to have standardised dimensions. Common world standards include ASA/ASME (USA), PN/DIN (European), BS10 (British/Australian), and JIS/KS (Japanese/Korean). In the USA, the standard is ASME B16.5 (ANSI stopped publishing B16.5 in 1996). ASME B16.5 covers flanges up to 24 inches size and up to pressure rating of Class 2500. Flanges larger than 24 inches are covered in ASME B16.47.

2023-08-29 Integral Flange: A Kind of Steel Flange Integral Flange Steel Flanges are widely used as a popular category of pipe fittings. Different from Slip on Flange and Blind Flange, the integral flange belongs to the flange standard system of the Ministry of Chemical Industry, which is a form of expression of the Ministry of Chemical Industry flange (also known as HG flange). In various domestic standards, simply use IF to indicate the integral flange, is a flange with a cone section neck. The integral flange is the part that connects the pipe to the pipe and is connected to the end of the pipe. There are holes on the whole flange, and the bolts make the two flanges tightly connected. The flanges are gasketed.

2023-02-01 Carbon Steel Reducers in Process Piping Reducers in Process Piping A reducer is a kind of pipe fitting used in process piping that reduces the pipe size from a larger bore to a smaller bore (inner diameter). A reducer allows for a change in pipe size to meet hydraulic flow requirements of the system, or to adapt to existing piping of a different size. The length of the reduction is usually equal to the average of the larger and smaller pipe diameters. There are two main types of reducer: Concentric reducers Eccentric reducers Reducers are usually concentric but eccentric reducers are used when required to maintain the same top-or bottom-of-pipe level. Concentric Reducer In Concentric Reducer the reduction of the pipe size is achieved by decreasing the diameter of the fitting at a constant rate over a specified length, maintaining symmetry around the fitting. Concentric Reducers are used to join pipe or tube sections of different diameters on the same axis. They provide an in-line conical transition between pressurized pi

2021-11-16 Pipe and Flange Fitting Materials Cast and malleable iron Fittings for cast iron pipe fall under hubless and bell-and-spigot styles. Hubless designs rely on elastomeric couplers that are secured to the outer diameters of the pipe or fitting by clamps, usually a stainless steel band clamp that compresses the elastomeric material and forms a seal. These hubless or no hub designs are sometimes referred to as rubber pipe couplings or rubber plumbing couplings and are especially popular for transitioning from one material to another-from copper to cast iron, for instance. Bell-and-spigot, or sometimes, hub-and-spigot, fittings are joined today

2021-10-16 Understanding Pipe Fittings from YPCO Factory Pipe fittings are components used to join pipe sections together with other fluid control products like valves and pumps to create pipelines. The common connotation for the term fittings is associated with the ones used for metal and plastic pipes which carry fluids. There are also other forms of pipe fittings that can be used to connect pipes for handrails and other architectural elements, where providing a leak-proof connection is not a requirement. Pipe fittings may be welded or threaded, mechanically joined, or chemically adhered, to name the most common mechanisms, depending on the material of the pipe. There is some inconsistency in terminology surrounding the terms pipe, tube, and tubing. Therefore, the term pipe fittings will sometimes be mentioned in the context of tubing as well as pipe. While similar in shape to tube fittings, pipe fittings are seldom joined by methods such as soldering. Some methods overlap, such as the use of compression fittings, but where these are commonplace for connecting tubes or tubing, their use

2023-12-04 Types of Pipe Fittings Used in Piping What are Pipe Fittings? Pipe Fittings are a Piping component that helps in changing the direction of the flow, such as elbows and tees.
