LR 90 degree steel pipe elbow are installed between different lengths pipe or tubing, It helps to change direction at 90 degree.

What is Galvanizing?

Galvanizing, or galvanization, is a manufacturing process where a coating of zinc is applied to steel or iron to offer protection and prevent rusting. There are several galvanizing processes available, but the most commonly offered and used method is called hot-dip galvanizing.

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.

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

ASME B16.9 butt welded fittings are American Standard BW fittings.COC Reducer means concentric reducer,BW reducers can be concentric (COC) reducer and eccentric (ECC) reducer.These reducers have same functions,the only difference is the internal structure.

Concentric reducers provide an in-line conical transition between pressurized pipes of different diameters. It is used to connect pipe segments or pipe segments on the same axis.

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.

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.

Long radius elbow refers to the pipe outer diameter with radius of curvature equal to 1.5 times, i.e R = 1.5D. Most elbows are available in short radius or long radius variants. When the two ends differ in size, the fitting is called a reducing elbow or reducer elbow.

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.

Whatis the difference between concentric and eccentric reducers?

A420 WPL6 tee is a pipe fitting with three ports, mainly used to divide a pipe into two branches or merge two branches into one pipe. Common ones are equal diameter tees and reducing tees. In the layout of the pipeline system, the structure of the tee can flexibly change the flow direction of the fluid to achieve the function of branching or merging.

The pipes cannot appreciate because of what the external arrangement of the pipe reducer seems but the flow of the pipe is changed by the internal width conical transition arrangement.

BW 90 deg elbow is the most used type of elbows in many industries.Schedule 80 is represents the wall thickness of the butt welded fittings.It is a commonly used wall thickness.another wall thickness is SCH 40.

BW elbow types have BW (butt welded),SW (socket weld),THD (threaded).The butt welded elbow is the most used type.Elbows have two shapes:Equal and Reducing.Shanghai Zhucheng is a pipe fittings manufacturer who can supply 45 deg,90 deg and 180 deg elbows.

24IN carbon steel BW elbows are large dimension fittings,ASME B16.9 is represents butt welded fittings in American Standard.Carbon steel fittings are used in many applications because of its great excellent functions.

The surface quality and mechanical properties of the elbow are almost the same as the pipe’s. To facilitate welding, the long radius elbow should be made of the same kind material of the pipe to be connected.

BW 90 degree elbow is usually be carbon steel for large dimensions.Butt welded 90 deg elbow also can be alloy steel and stainless steel.Steel pipe fittings are used in piping systems in many industries.

Concentric reducers facilitate the delivery of mud and abrasive fluids and are suitable for corrosive operations and where different ratings and wear protection are required between flanges.

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.

Carbon steel pipe fittings are used in many applications because of its great excellent functions.Carbon steel pipe fittings can manufactured as THD (threaded) fittings,SW (socket weld) fittings and (BW) butt welded fittings.The specifications are in the content below.

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

BW reducers have two types:Concentric Reducer and Eccentric Reducer.These two types can meet different demand.This is stainless steel BW COC reducer in the picture.Stainlee steel is better in corrosion resistance,so the used years will be longer than other matercial.

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.
