CARBON STEEL BUTT WELD 45º ELBOW A234WPB LR/SR

Steel pipe bend is belong to butt welded fittings,bends have some similar usages as elbows.However,bends can be customized by clients to satisfy different demands.API 5L B is a grade of carbon steel material for pipes and bends.

304/316L BW tees are the most used tees in stainless steel tees.304/316L are the most used grades in American Standard.Tees can be Equal Tees and Reducing Tees.You could find the summary “Equal VS Reducing Tee” in the content below.Stainless steel pipe fittings are populat because of the excellent functions of corrosion resistance.

Steel tee is a T-shaped pipe fittings that has three branches, normally has two forms with Equal Tee and Reducing Tee, both are used to divide the pipelines to adjust the flow rate and change the direction.

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.

Pipe tees can be equal tee and reducing tee.These tees have same functions,the only difference is reducing tee can reduce the flow in piping system.ASME B16.9 is American Standard for butt welded fittings.

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.

A equal tee’s usage,dimension and features.

A 90 degree elbow attaches readily to plastic, copper, cast iron, steel and lead. It can also attach to rubber with stainless steel clamps. Elbow connectors can link pipes to avoid water leakage and air leakage between pipes.

Concentric reducer’s dimnesions and its usage and advantage

A234 WPB elbow is the most chosen carbon steel elbow in all the types of elbows.A234 WPB is carbon steel grade for butt welded fittings;BW elbows have LR (long radius）and SR (short radius).Elbows have 90deg and 48deg to change the direction of the pipe system.

Concentric BW reducer is one type of butt welded fittings.BW reducers can be concentric (COC) reducer and eccentric (ECC) reducer.These reducers have same functions,the only difference is the internal structure.

BW Elbow Fittings can also attach to rubber with stainless steel clamps. Available in many materials like silicon, rubber compounds, galvanized steel etc,

Carbon steel butt weld reducer is belong to ASME B16.9 pipe fittings,there are concentric reducer and eccentric reducer for chosen to meet different demands.

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.

Lap joint stub end is belong to butt welded fittings,lap joint stub end is not usually used in many time.Lap joint stub end always be used with lap joint flange.Stainless steel pipe fittings are popular because stainless steel’s excellent performance in corrosion resistance.

Concentric reducer is used to join pipe sections or tube sections on the same axis. It is cone-shaped, and is used when there is a shift in diameter between pipes. A pipe reducer is available in various specifications, such as a single diameter change and also in a multiple diameter change.

What is a CONCENTRIC REDUCER and what about its specification and advantages.

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

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.

SS400 90 DEG elbow is used to transport flow in piping system.Butt welded fittings used welded connection to connect with the pipes to achieve the strong and premanent connection.

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.

316L 90 deg elbow is a stainless steel pipe fitting which can used in chemical environment because of its an-ti corrosive function.SCH 10S is repersents to the wall thickness in butt welded fittings. Commonly used wall thickness is SCH 40 and SCH 80.Stainless steel pipe fittings are popular because of the an-ti corrosive function.Stainless steel pipe fittings can used over 50 years.

BW cap is used to close the pipe system,the function is similar to plug.A234 WPB is a commonly used grade for carbon steel in American Standard.SCH 40S is represents a wall thickness of butt welded fittings.The commonly used wall thicknesses for BW fittings are SCH 40,SCH 80.

90 degree elbow’s usage and its specification

Butt welded tee can be equal type and reducing type.Both types can change the direction of the piping system in 90 deg.In addition,the reducing tees can reduce the flow of the fluids or gas.Shanghai Zhucheng is an excellent pipe fittings manufacturer from China who supply high quality fittings for years.

BW 3D elbow is belong to Butt welded (BW) elbows.3D means the radius is 3 times of dimensions long.A234 WPB is the most used grade of carbon steel butt welded (BW) fittings according to American Standrad.The degree of the butt welded 3D elbow can be 45 deg, 90 deg and 180 deg.
