ASTM A234 specification has many grades, such as WPB, WPC, WP5, WP9 WP11, WP12, WP22, WP91 and so on. In these standard Grade WPB is the most common material used for medium and high temperature pipelines. W means weldable, P means pressure, B is grade b, refer to the minimum yield strength.
ASTM A403 Stainless Steel Butt Weld 45 Degree Elbow refers to the material of forged and rolled austenitic stainless fittings for pressure pipes. Common grades are WP304/L, WP316/L. They can be used into many fields as engineering industry, energy conversion plants etc. ASTM A403 WP304, WP316 Elbow are buttweld fittings made for austenitic stainless steel applications with forged material.
45° Pipe Elbow is also known as “45 bends or 45 ells”. The 45° pipe elbow is used to connect tubes at a 45° pipe angle. As the name suggests, this is a pipe fitting device which is bent in such a way to produce 45° change in the direction of flow of the fluid/gas in the pipe.
The function of butt weld elbow is to change direction or flow in a piping system. There are the 45°, 90° and 180° . According to the material, it can be divided into carbon steel, alloy steel and stainless-steel. According to its radius of curvature, there are long radius and short radius butt weld elbow.
The function of an elbow and What is the difference between LR and SR elbow?
ASTM A234 WPB pipe fittings are have a large size:1/2″-80″.32 in carbon steel butt welded elbow is a common used size in large size of BW elbows.
Butt weld fittings would also be referred to as welded pipe fittings. When these would be used in stainless steel and carbon steel, they would be able to offer certain advantages as compared to socket weld and threaded fittings. Whereas socket weld would only be available up to a specific size, you would find butt weld fittings to be available in sizes starting 1/2 inch to 72 inch.
90 degree elbow’s usage and its specification
ASTM A182 F304 pipe fittings are inculding many fittings,among these,stainless butt welded elbows are the most common used fittings.For 90 deg elbows,there are two types :LR (Long Radius) and SR (Short Radius).Stainless steel pipe fittings are popular because of the superior functions.
Steel pipe elbow is a key parts in a piping system for to change the fluid flow direction. It is used to connect two pipes with same or different nominal diameters, and to make the pipe turn to a certain direction of 45 degree or 90 degree.
Butt weld fittings are manufacture by seamless or welded pipe. For pipe fittings manufacturers, the forming process of welded pipe and seamless pipe is basically same. Butt welded fittings can be divided into carbon steel butt welded fittings and stainless-steel butt-welded fittings
Buttwelding Fittings Specification Shape: Elbow, Tee, Cross, Bend, Reducer, Cap, Stub End Size Range: 1/2″ – 80″ / DN15 – 2000 Thickness Schedule: SCH 10,SCH 10S, SCH 20, SCH 40,SCH 40S, STD, XS,SCH 80, SCH 80S, SCH 100, SCH 120, SCH 160, XXS
Butt Weld Fittings include elbows, tees, cross, caps and reduces. These fittings are the most common type of welded pipe fitting and are specified by nominal pipe size and pipe schedule. Buttweld fittings are manufacture by seamless or welded pipe and are formed to get the shape of elbows, tees and cross etc.
Elbow is a pipe fitting that changes the direction of piping. According to the Angle, there are 45° and 90°180° three most commonly used. Elbow material can be divided into carbon steel, alloy steel and stainless-steel.
