ASME B16.9 Pipe Fittings Butt Weld 90° Elbow

45 deg elbow has three types:BW,SW,THD.Among these,The commonly used elbows can be 45 deg and 90 deg.BW (butt welded) 90 degree elbows have LR (long radius) and SR (short radius) while 45 degree elbows only have LR type.

Butt welded elbow,also called BW elbow,there are two types elbows:Reducing Elbow and Equal Elbow.both types elbows can change the fluids or gas in 45 deg or 90 deg,while reducing elbows also can reduce the flow in the piping system.Shanghai Zhucheng has experienced steel pipe fittings factory to supply high quality fittings.

BW (butt welded) reducer have two types:Eccentric Reducer and Cocentric Reducer.Reducer only has welded connection.However,swage nipple which belong to forged fittings has same function to reducer.

It can have concentric reducer and eccentric reducer. It is widely used in pipeline installation projects, such as when the diameter of the pipeline needs to be changed at the inlet and outlet of the pump

Steel pipe elbow is a key part in a pressure piping system used to change the fluid flow direction. It is used to connect two pipes with same or different nominal diameters, and to make the pipe and thus the fluid direction turn to a certain direction of 45 degree or 90 degree. This change in fluid flow direction adds pressure losses to the system due to impact, friction and re-acceleration.

A234 WPB/WPC BW 90 degree elbows are carbon steel butt welded fittings.Elbows also have 45 degree.These elbows have similar functions,the only difference is the 90 degree elbow can changes the direction in 90 deg while the 45 degree elbow can changes in 45deg.

90 degree elbow, also called “90 bends or 90 elbows”, are manufactured as SR (Short Radius) elbows and LR (Long Radius) elbows.

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.

90 deg elbow is always used in piping systems.The other degree of elbows is 45 deg elbow.These elbows have similar functions,the only difference is the 90 degree elbow can changes the direction in 90 deg while the 45 degree elbow can changes in 45deg.A403 WP316L is a grade for stainless steel in American Standard.

An elbow is a pipe fitting installed between two lengths of pipe or tubing to allow a change of direction, usually a 180° or 90° angle, though 45° elbows are also made. The ends may be machined for butt welding (SW) or socketed welding(SW) etc.

The length dimension of the reducer is almost equal to the average of the big bore and smaller bore pipe diameters. Concentric reducers are easy to transport mud and grinding fluid and are suitable for corrosive operations

Carbon steel tee is the most used type in all tees because carbon steel has great functions and affordable price.Galvanized pipe fittings has better anti-corrosive function than normal carbon steel pipe fittings,galvanized fittings have similar functions as stainless steel fittings,but the price is cheaper than stainless steel fittings.

Stinless steel pipe is always used in many corrosive environments because of the excellent anti-corrosive function,so that the pipes can used for longer years than other materials’ pipes.Shanghai Zhucheng is a superior steel pipe supplier who supplys high quality pipes for years.

Fittings that change direction in a piping system are called elbows which available in 90 degree and 45 degree long radius elbow. Both of them has the center line at 1.5 x NPS from elbow end.

According to the production process, it can be divided into: welding elbow, stamping elbow, pushing elbow, casting elbow, butt welding elbow, etc. Other names: 90 degree elbow, right angle bend, etc.

The stub end is usually a short section of pipe fittings, with one end being a flap structure, and the other end can be a stub end or special processing according to specific needs. The turning part is designed to facilitate the connection with other pipe fittings or equipment.

BW 90 elbow is the most used degree,there is also 45 deg elbow to choose.These elbows have similar functions,the only difference is the 90 degree elbow can changes the direction in 90 deg while the 45 degree elbow can changes in 45deg.ASME B16.9 is American Standard of butt welded fittings.

An equal tee, otherwise called straight tee, means the branch diameter of this tee is same with the main pipe (Run pipe) diameter of this tee.
A pipe tee is defined “equal” when the bore size at the run and branch sides have the same diameter. An equal tee is, therefore, used to connect two pipes of the same nominal diameter.

S31803 90 degree elbow is a kind of stainless steel with two-phase structure of ferrite and austenite. It combines the high strength of ferritic stainless steel with the good toughness and corrosion resistance of austenitic stainless steel.

The function of an elbow and What is the difference between LR and SR elbow?

ASTM A234 WPB Eccentric Reducers are pipe fittings used to connect two pipes of different diameters, with the centerline of one pipe being offset from the other.

Large Diameter Concentric Reducer is belong to butt welded fittings because BW fittings size range is 1/2″-80″ while the forged fittings only have 1/8″-4″.ASTM A234 WPB is represents to carbon steel pipe fittings in American Standard.

Concentric reducers will change kindly between the pump and piping， Concentric reducers are used to connect pipe segments or pipe segments on the same axis.

What is a pipe bend,what about its specification and its difference between a elbow

Concentric Reducer (COC Reducer),is one type of BW reducer.The other type is Eccentric Reducer (ECC Reducer).The two types reducers can meet different demands,You could find the “Concentric VS Eccentric” below to learn the usages for these two types reducers.

ASME B16.9 tee is an American Standard butt welded fitting.BW tees can be two types:Equal Tees and Redcing Tees.These tees have similar functions but reducing tees can reduce the flow while equal tees can not.You could find the summary “Equal VS Reducing” in the content below.

BW elbows are belong to butt welded fittings,wall thickness of BW fittings decided the pressure that the fittings can resistance.Wall thickness SCH 40 is a commonly used wall thickness in butt welded fittings.

Stainless steel BW tees are always used in many corrosive environments because of the corrosion resistance of stainless steel.ASTM A182 F316 is a commonly used grade for stainless steel.Stainless steel pipe fittings are popular because of the an-ti corrosive function.Stainless steel pipe fittings can used over 50 years.
