ASTM A234WPB Butt Weld Concentric Reducer Fittings

Steel pipe elbow is an important parts in plumbing pipeline systems and used to change the fluid directions. It ranges in different types as per body material there are stainless steel elbow, carbon steel elbow, and alloy steel;

45 deg BW elbow can change the direction of fluids or gas by 45 deg,it only has LR (long radius) type while 90 deg butt welded elbow has both LR and SR(short radius) types.Carbon steel is the most used material in pipe fittings because it has great functions to satisfy many applications.

Concentric reducers are perfectly suitable to use in the exclusion of the pump. 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.

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.

Steel bend is almost same as pipe elbow. It’s radius is bigger and extensive used in oil and gas, engineering and construction industry.

Steel pipe cap is usually welded onto end of pipe that blcok off the piping line system, it has same funtion with plug and blind flange. It is available in material of carbon steel, stainless steel and alloy steel.

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.

45 degree elbows have same functions to 90 degree elbows,the only different is 45 deg elbow changes the direction of pipes in 45 deg while the 90 deg elbow changes the direction in 90 deg.BW pipe fittings are popular as its strong and permanent connection.

Bending radius less than or equal to 1.5 times of pipe diameter belongs to elbow, and bending radius greater than 1.5 times of pipe diameter belongs to elbow

ASTM A234 WPB Butt Welded Fittings are the best selling products in Shanghai Zhucheng Pipe Fittings Manufacturing Co Ltd from China.We can also supply customers forged pipe fittings,pipes and some related products.

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.

Carbon steel elbows are curved connecting pieces that join straight lengths of pipe, commonly at a 90° or 45° angle, allowing obstructions to be avoided in plumbing, ventilation, welding, and automotive applications.

he 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.

90° Steel Pipe Elbow is the most commonly used elbow type in pipe system with the function to change the direction of fluid in 90 degree. It connects pipes with same or different diameter.

BW tees and reducers are the most used pipe fittings in the piping system.Tees can branch the flow in piping systems.Carbon steel pipe fittings are popular as the great functions and affordable functions.

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.

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).

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.

There are 45 ° elbows and 90 ° elbows in common use. Those with a bending radius of about 1.0 times the outer diameter of the pipe are called short radius elbows; The long radius elbow is about 1.5 times the outer diameter of the pipe

Radius of Long Radius (LR) Elbows is 1.5 times the pipe diameter. Radius of Carbon Steel Short Radius Elbow is 1.0 times the pipe diameter. Carbon Steel Seamless Elbow are in demand for use between two lengths of pipe or tube allowing a change of direction, usually these elbows distinguished by connection ends.

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.

An equal tee, otherwise called straight tee, means the branch diameter of this tee is same with the main pipe (Run pipe) diameter of this tee.
A pipe tee is defined “equal” when the bore size at the run and branch sides have the same diameter. An equal tee is, therefore, used to connect two pipes of the same nominal diameter.

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.

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.

Stainless 90 deg elbow has better anti-corrosive function than other material elbows.90 degree elbow can be two types: LR (long radius) and SR (short radius).Elbows can also be 45 degree,but 45 deg elbow only has LR type.

Steel pipe tee is a pipe fitting used to tansport the flow in the piping system.Carbon steel fittings are used in many applications becasue of its great excellent functions.
