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. Types of Elbows based on Length and Radius Elbows are split into two groups which define the distance over which the flowing fluid change direction; the center line of one end to the opposite face. This is known as the [Center to Face" distance and is equivalent to the radius through which the elbow is bent. If the radius is the same as pipe diameter (Center-to-Face dimension of 1.0 X diameter ), it called Short Radius Elbow (SR elbow) used normally for low pressure and low speed pipelines or in tight areas where clearance is the main issue. If the radius is larger than pipe diameter (Center-to-Face dimension of 1.5 X diameter) then we call it a Long Radius Elbow (LR Elbow) used for high pressure and high flow rate pipelines. Types of Elbows based on Connection with Pipe As per the connection with pipe, elbows could be classified as Butt Welded Elbow, Socket Welded Elbow and Threaded Elbow. Butt Welded Elbow Butt weld elbow is a steel elbow formed by hot pressing or forging. Its connection form is to directly weld the elbow and steel pipe. Butt welded elbows have beveled ends to allow for ease of welding. This bevel allows for full penetration weld in most of the cases. Butt welded elbows are mainly used for elbow with higher pressure and temperature. Socket Welded Elbow Socket weld elbow is also welded to the pipe and fittings end. Unlike the butt weld elbow, the socket weld elbow has a trapezoidal area at the end. We can insert pipe end into this area (the diameter of SW elbow is matched with the outer diameter of pipe), then do welding work to connect them together. Therefore, the actual diameter of SW elbow end is greater than the elbow diameter. Threaded Elbow The shape of threaded elbow is similar to the SW elbow, except that the inner surface of the trapezoidal area has been machined into thread. It is easier to install and remove, good for pipeline repair and maintenance. Types of Elbows based on Material of Construction Stainless Steel Elbow : ASTM A403 WP Gr. 304, 304H, 309, 310, 316, 316L, 317L, 321, 347, 904L Carbon Steel Elbow : ASTM A 234 WPB , WPBW, WPHY 42, WPHY 46, WPHY 52, WPH 60, WPHY 65 & WPHY 70.

Few of them has been defined below. Reducing Elbow A reducing elbow is a type of fitting which is used to join two pipes of different sizes. The reducing elbow is so called because it looks like a reducing piece and elbow combined into one. The reducing elbow eliminates one pipe fitting (reducer) and reduces the welding by more than one-third. Also, the gradual reduction in diameter throughout the arc of the reducing elbow provides lower resistance to flow and reduces the effect of stream turbulence and potential internal erosion. These features prevent sizable pressure drops in the line. For many suppliers it is a non standard item resulting into high price with a long delivery time. The use of a [normal" elbow with a separate reducer is an option if the situation allows. Male Pipe Elbows & Female Pipe Elbows Male pipe elbows and female pipe elbows are popular tube fittings which provide an fluid flow directional change of a tubing run. While a male pipe elbow is used to connect fractional tube to female tapered pipe thread, a female elbow is used to connect fractional tube to male NPT thread. These types of tube fittings like male elbows and female elbows have been specifically designed for use on instrumentation, process and control systems and equipment employed in chemical, petroleum, fluid power, electronic and pulp and paper plants. Wall Thickness of Elbows The weakest point on an elbow is the inside radius. ASME B16.9 only standardizes the center to face dimensions and some [squareness" dimensional tolerances. The wall thickness at the weld line location even is standardized, but not through the rest of an elbow. The standard states that the minimum tolerance will be within 12.5% of the minimum ordered wall thickness of the pipe. A maximum tolerance is specified only at the ends of the fitting. Many providers of butt weld elbows provide one schedule greater thickness so that sufficient wall thickness, after forming, remains.

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. Cangzhou Youlong Pipe Fitting Manufacturing Co., LTD is mainly engaged in the processing and manufacturing of antiseptic and insulated pipe fittings,operates pipe fittings, flanges, steel pipes and other products..

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 Plastic Alloy steel Stainless steel etc. Uses of reducing tees: Reducing tees are used to provide high integrity mechanical connections in various pumping applications. Are widely used for positive pressure and vacuum applications. Used in ultra high purity systems.

Reducing tee usually provides smooth flow paths and there is no turbulence or entrapments. Used for waste, water supply. Used for water, drain pipe , gas , oil etc. Product Category 45 Deg Elbow 90 Deg Elbow CON Reducer ECC Reducer Reducing Tee Equal Tee Carbon Steel Caps Slip On Flange Welding Neck Flange

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 Uses of pipe reducer: A pipe reducer serves the two basic purposes: Changing the piping diameter Handling the expansion, misalignment or vibration problem Types of Pipe Reducer: Let us know more about pipe reducers under the following categories: Product Category 45 Deg Elbow 90 Deg Elbow CON Reducer ECC Reducer Reducing Tee Equal Tee Carbon Steel Caps Slip On Flange Welding Neck 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 PVC Thermoplastics Aluminum Brass Bronze etc. Key Features: The recess on the inside diameter of the socket weld flange allows for a good fit of the pipe allowing for a smooth flow of liquid. Socket welding flanges work well for smaller sizes and higher pressure temperature conditions. They are similar to slip-on flanges, but must specify the schedule of the pipe where they will be used for with socket welds. Uses of socket weld flanges: They are ideal for small diameter applications. They are used for high pressure applications. Socket weld flanges have an internal recess on the inside diameter which allow for a smoot flow of the process fluid. They create a smooth bore with the proper welding and grinding.

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 are for all types of piping inside a building. They are also used in water supply lines, but not in gas pipelines. Carbon Steel: Carbon steel is much more durable and stronger than other varieties of steel, which makes it suitable for making pipe fittings. Also known as plain carbon steel, carbon steel is a malleable and iron-based metal, containing mainly carbon and small amounts of manganese and other elements. Steel is subjected to various processes and can either be cast to shape or wrought into various mill forms from which finished parts are formed, forged, stamped, machined or otherwise shaped. Carbon is the main hardening and strengthening element present in steel, which offers maximum hardness and strength; and decreased ductility and weld-ability. Carbon steel pipe fittings come in various sizes and shapes. Again there are some butt-weld carbon fittings, which feature beveled edges and form a channel of lesser depth for the bead of weld that fixes the piece together. Butt-weld fittings are mainly used to join sections of pipe where permanent and welded connections are required. Elbows, reducers, tees, etc are made of butt-weld steel fittings. Application of Carbon steel fittings: Fittings made of carbon steel are used in pipe pipe systems that carry liquids or gases, such as oil, water, natural gas, or steam. Apart from that, carbon steel fittings are highly demanded in construction and maintenance activity in the residential construction, commercial construction, electric-power generation, petroleum refining, shipbuilding and other industrial-use sectors. Stainless steel: Stainless steel is widely used for making pipe fittings because of the fact that it is highly resistant to oxidation and corrosion in various natural and man-made environments. Stainless steel is actually a ferrous alloy containing minimum 10% chromium. Selection of right grade of stainless steel for a particular application is really important. A range of pipe fittings like tees, unions, elbows, etc are made of stainless steel. Stainless steel fittings are usually used for household pipelines.
