90 DEG 4D Bend API A53B

These concentric reducers are available in the seamless and welded type of construction. 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.

Concentric reducer’s dimnesions and its usage and advantage

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.

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.

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.

A234 WPB BW tee is a commonly used pipe fitting to transport flow in piping system.There are two tpyes of tees:Equal Tee and Reducing Tee.SCH 80 is a commonly used wall thickness for butt welded fittings,the other commonly used wall thickness is SCH 40.

Specificationo and usage of a 90degree BW elbow.

Pipe crossing is used where four pipes intersect. The cross pipe may have one inlet and three outlets, or three inlets and one outlet. The diameter of the outlet and inlet can be the same or different.

Elbow is a fitting device which is bent in such a way to produce 90 degree change in the direction of flow of the content in the pipe.

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.

ASTM A182 F316 is a popular grade for stainless steel in American Standard.Stainless steel fittings are popular because of the an-ti corrosive function.Stainless steel pipe fittings can used over 50 years.

The two ends of concentric reducer are designed with large diameter and small diameter, and the pipe is connected through conical transition section on the same axis.

Reducing tee is a commonly used fittings to branch the pipes and reduce the flow in the piping systems.Large dimension is for butt welded fittings.ASME B16.9 pipe fittings are BW fittings according to American Standard,the size range for the ASME B16.9 fittings is 1/2″-80″.

Reducing tee is used to change the direction and reduce the flow of the fluids or gas.Butt welded pipe fittings can weld with the pipes so that can anti leakage effectively.Tees have two types:Equal Tee and Reducing Tee.The commonly used wall thicknesses for butt welded fittings are SCH STD,SCH 80,SCH 160.

BW (butt welded）reducer has two types:concentric reducer and eccentric reducer.As it is butt welded fitting,its size can be 1/2″ – 80″,so butt welded fittings can be used in many applications.Stainless steel fittings are more expensive but the functions are also better than others.

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

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.

According to its radius of curvature, there are long radius elbow and short radius elbow. Long radius elbow refers to its radius of curvature is equal to 1.5 times the outside diameter of the pipe, that is, R=1.5D; A short radius elbow means that its radius of curvature is equal to the outer diameter of the pipe, that is, R= 1.0d.(D is the diameter of the elbow, and R is the radius of curvature).

It is used to handle any high or low weight fluid flow through the tee.Reducing tee is a kind of pipe fitting whose branch size is smaller than the size of pipeline parts. It is used for main pipe string accessories, solvent welding accessories, side outlet and conflicting soluble welding accessories.

Classify of elbows and how to sperate it into SR and LR Elbows

BW carbon steel reducer is the most used type of BW reducers.Butt welded reducer can be concentric (COC) reducer and eccentric (ECC) reducer to meet different demands.SCH 160 fittings are belong to large wall thickness,these fittings can resist high pressure in piping system.

ASME B16.9 BW 90 elbow is pipe fitting manufactured according to American Standard.ASME B16.9 is American Standard of butt welded fittings.There is BW elbow in the picture,you could find the specification and dimensions below.

A182 F316 reducer is a stainless steel butt welded fitting which can used in some corrosive environments because of the high corrosion resistance of stainless steel.BW reducers can be concentric (COC) reducer and eccentric (ECC) reducer.There are many differences between the two types of reducers,you could find the summary “Concentric VS Eccentric” in the content below.

Steel pipe bend is a butt welded fitting to transport fluids or gas.The degree of steel bend will be customize according to the client’s demend.Pipe bend and elbow have some similarity,you could find the summary “pipe bend VS elbow” below.

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.

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.
