ASMEB16.9 11/2 IN ASTM A53B 4D Bend

90 deg elbow is the most used degree in elbows,.Butt welded fittings including BW elbows which used welded connection to connect with pipes.There is also 45 degree elbows.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.

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.

The lap joint stub end is required when attach the lap-joint flange to the piping system. The stub end and lap-joint flange assembly are used mainly in piping systems that necessitate frequent dismantling for inspection or routine maintenance.

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.

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.

According to its radius of curvature, it can be divided into long radius elbow and short radius elbow. Long radius elbow means that its radius of curvature is equal to 1.5 times the outer diameter of the pipe, that is, r = 1.5D. Short radius elbow means that its radius of curvature is equal to the outer diameter of the pipe, that is, r = 1.0d.

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.

The function of a 45 Degree Long Radius Elbow is same as 90 degrees long and short elbow, but the measurement and dimensions are different to that of a 90 degree long and the short elbow.

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 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

Concentric reducers are tapered and are used when the diameter between pipes changes. It can be axially shifted and externally reconfigured to offer more efficient reducer connection.

Carbon steel butt welding 90 degree elbow is a connector specially designed for use in piping systems. Its main function is to create a 90 degree turn in the pipe so that the fluid can flow along a predetermined path.

90 deg 4D bend is belongs to butt welded fittings.4D means the radius of the bend is 4 times long the dimension of the pipe bend.API A53B is a great of carbon steel materical for pipes and bends in American Standard.

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 are mainly used for elbow with higher pressure and temperature than other connection types. According to the valve body material, it has stainless steel, carbon steel and alloy steel elbow

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.

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.

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.

90 deg LR (long radius) elbow is the most used type of BW elbows.Butt welded elbows also have SR (short radius) elbows.Shanghai Zhucheng has experienced pipe fittings factory that can supply high quality goods for many years.

Branches of tees have two types:Equal tee and Reducing tee.These two types tees have same functions,but reducing tee has one more function:it can reduce the flow of the gas or fluids.Butt welded fittings are the most used fittings in many applications because the size range of the BW fittings is big.

45 deg elbow can be butt welded elbow and forged elbow.Forged elbows are including SW (socket weld) elbow and THD (threaded) elbow.Stainless steel pipe fittings are popuar because stainless steel has excellent corrosion resistance,stainless steel has using age over 50 years,so the material is more expensive than other materials.

Pipe elbows are fitting accessories which are used widely in various industrial sectors in pipe fitting. A pipe elbow is frequently used in pressurized applications and are available in various shapes and sizes for use in different applications. A pipe elbow is a fitting installed between two lengths of pipe or tube allowing a change of direction, usually in the 90° or 45° direction.

Butt welded elbow is a pipe fitting which used welded connection to connect with the pipes in piping system.BW elbbows have two degrees to choose:90 deg elbow and 45 deg eblbow.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.

BW elbow is popular because of the strong and permanent connection.The anti corrosion function of carbon steel and alloy steel is not as good as stainless steel,so coated pipes and fittings have paint or oil to protect the fittings during sea transportion.

DN900 LR elbow is large dimension fitting,for the large dimension,the elbows always be butt welded.Wall thickness STD is a commonly used thickness of BW fittings,the other commonly used wall thickness are SCH 40, SCH 80.

5in SW elbow is used to socketed with pipes and then welded on pipes.ASME B16.11 pipe fittings mean forged pipe fittings.Forged pipe fittings can be divided in socket weld fittings and threaded fittings.

Carbon steel elbow has two degrees:90 deg and 45 deg.In real application,90 deg is more used type.90 deg elbow can be long radius (LR) and short radius (SR) while 45 deg elbow only has long radius (LR).

What is a Concentric Reducer,what about its specification and advantages.

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.
