What is Galvanizing?

Galvanizing, or galvanization, is a manufacturing process where a coating of zinc is applied to steel or iron to offer protection and prevent rusting. There are several galvanizing processes available, but the most commonly offered and used method is called hot-dip galvanizing.

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.

90 deg elbow is always used in piping systems.The other degree of elbows is 45 deg elbow.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.A403 WP316L is a grade for stainless steel in American Standard.

Steel pipe bend two pipes into a certain angle and connects them together to change the direction of the pipe. it could be bend directly from a finished pipe with cold bending processes, to different degrees.

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.

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.

Pipe elbows have three types:THD (threaded),SW (socket weld),BW (butt welded).These elbows used different connections to connect with the pipes in piping system.Stainless steel fittings are popular because of the an-ti corrosive function.Stainless steel fittings can used over 50 years.

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 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.Schedule 80 is represents to the wall thickness of BW fittings.The most used wall thicknesses of butt welded fittings are SCH 40,SCH 80.

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.

What is a pipe Tee,its specification and importance.

ASTM A234 specification has many grades, such as WPB, WPC, WP5, WP9 WP11, WP12, WP22, WP91 and so on.
In these standard Grade WPB is the most common material used for medium and high temperature pipelines. W means weldable, P means pressure, B is grade b, refer to the minimum yield strength.

It can be axially shifted and externally reconfigured to offer more efficient reducer connection. Concentric reducers facilitate the delivery of mud and abrasive fluids and are suitable for corrosive operations and where different ratings and wear protection are required between flanges.

Butt welded fittings,can be abridged as BW fittings.Butt welded means the pipe fittings used welded connection to connect with pipes.BW fittings including Elbow, Tee, Cross, Bend, Reducer, Cap, Stub End.Carbon steel always be the material of these fittings as carbon steel has great functions and affordable price.

45 deg elbow is a type of elbows,there are also 90 deg elbows and 180 deg elbows.These elbows have similar functions,the main difference is the degree.Elbows can be BW,SW and THD to chosen for different applications.Shanghai Zhucheng is a quality pipe fittings supplier from China.

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.

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.

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.

Concentric reducers will change kindly between the pump and piping， A pipe reducer is available in various specifications, such as a single diameter change and also in a multiple diameter change.

There are two types of 90 deg elbows:LR (long radius),SR (short radius).45 deg eblows are also have wide applications,be attention,45 deg elbow only have LR type.Butt welded pipe fittings have the most large used range as it can be 1/2″ – 80″.

Steel pipe bend is belong to butt welded fittings.The bend radius R should greater than or equal to 3 times of the outside diameter.Bends could manufacture as the customize degree to meet the client’s demends.

Fittings that change direction in a piping system are called elbows which available in 90 degree and 45 degree long radius elbow. Both of them has the center line at 1.5 x NPS from elbow end.

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 (COC) reducer is one type of BW reducer.The other type of reducer is Eccentric (ECC) Reducer.The different of COC Reducer and ECC Reducer is the internal structure.BW pipe fittings are popular because of the strong and permanent connection.

Concentric reducers are beneficial to use where different ratings and to wear protection is required in conveying between flanges or pipes. nd the pipe is connected through conical transition section on the same axis.
