Butt Welded Fittings Carbon Steel

The function of butt weld elbow is to change direction or flow in a piping system. There are the 45°, 90° and 180° .
According to the material, it can be divided into carbon steel, alloy steel and stainless-steel.
According to its radius of curvature, there are long radius  and short radius butt weld elbow.

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.

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.

Equal diameter tee, also known as straight tee, the branch diameter of the tee is the same as the pipe diameter of the tee. The three branches of tee have same diameters.

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.

Alloy steel butt-weld pipe caps are mainly used to close pipeline systems to ensure that the fluid in the pipeline will not leak.It is usually welded at the end of the pipeline to provide a reliable sealing effect.

Butt welded elbow is a commonly used pipe fitting,it can divided as two types:90 deg and 45 deg.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.These are Shanghai Zhucheng Pipe Fittings Manufacturing Co Ltd’s steel pipe fittings packages to ensure that the products are not damaged during transportation.

A234 WPB/WPC BW concentric reducers are carbon steel butt welded fittings,among these,A234 WPB is more chosen in many industries.BW reducers can be concentric (COC) reducer and eccentric (ECC) reducer.These reducers have same functions,the only difference is the internal structure.

Butt welded cap is a pipe fitting used to closed the piping systems.BW caps use welding connection to connect with the pipes.SCH 80 is a commonly used wall thickness of BW fittings,the other commonly used wall thickness is SCH 40.

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 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.

Stainless concentric reducer is belong to BW (butt welded) fittings.Reducer can be two types:Concentric (COC) Reducer and Eccentric (ECC) Reducer.The main difference of these two typws are the internal structure.Stainless steel pipe fittings have better functions than other material pipe fittings.

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 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.

Carbon steel elbows are the most commonly used elbows in all the types and material elbows.Large dimensions elbow is butt welded fitting,you can find the butt welded fittings specification below.

oncentric reducers are beneficial to use where different ratings and to wear protection is required in conveying between flanges or pipes.

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.

ASME B16.9 Stainless Steel Butt Weld Cross Fittings The function of a cross is similar to that of a tee by means of the exception of providing two 90 Deg outlets opposite each other.

45 degree elbow produces less friction, and with the lower pressure. 45 degree elbow is widely used in chemical industry, food, water supply facilities, electronic industry, chemical pipeline, horticulture, agricultural production, solar equipment pipeline, air conditioning pipeline and other fields.

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.
