When we talking about large diameters pipe, It usually refers to the pipe in welded like LSAW pipe or SSAW pipe; More over, it also includes large diameter seamless pipe in some circumstances. It shall be noted that for a high pressure pipeline large diameter seamless pipe is preferred.

  Carbon steel has high tensile strength for any material. It can bend and stretch into any shape without losing any strength. Using this feature, the carbon steel pipe can become thinner and maintain the ability to contain flowing materials under high pressure.

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.

Welded steel tubes have a very wide used range as it can be both small and large dimensions.Welded steel tubes have many types:LASW,SSAW,ERW.Among these,ERW is the most used type.

Carbon steel pipes have many grades to satisfy different applications.The most used carbon steel pipe is API 5L B.And there are also other grades for carbon steel pipe:A53 B,A106B.Although these are all carbon steel,the different chemical compositions meet different needs.

Steel resistant to weak corrosive media such as air, steam and water or stainless steel is called stainless steel. Seamless steel pipe is a kind of circular steel pipe, in which there is no joint around the empty part. Welded steel pipe is a tubular product made of flat plate, which is formed, bent and ready for welding.

Seamless pipe (SMLS) has great anti leakage function,so it has a widely used in fluid or gas transportation.Shanghai Zhucheng is an excellent high pressure pipe supplier from China.We also supply welded steel pipes；LSAW,SSAW,ERW are types we can supply.

The threaded pipe union is similar to the coupling and can be flexibly disassembled when it needs to be repaired or replaced. The reducing threaded union is easy to disconnect and link, and can be operated multiple times. Threaded Types includes NPT , PT , BSPP,  BSPT,and  PF.

Stainless steel seamless pipe is usually be chosen because of its great anti leakage and anti corrosion functions.A789 UNS S32750 is represents super duplex stainless steel.Stainless steel pipe has two types:seamless and welded.Seamless steel pipes always be small dimensions while large dimensions always be welded.

A pipe Thread elbow is actually a fitting that is being installed in between the two lengths of tube or a pipe to allow in changing the direction of a flow.A pipe Threaded Elbow is actually a fitting that is being installed in between the two lengths of tube or a pipe to allow in changing the direction of a flow. The change in the direction is done generally in the 45°or 90°route.

Hex head bushing is a commonly used bushing,there is also has flush bushing.Bushing is belong to forged fittings and it only available in threaded type.Threaded pipe fittings are easy to Installation and removal.

SW (socket weld) elbow is high pressure forged fitting which can used in many industries ‘ pipe systems.SW elbows have 90 deg and 45 deg.SW elbows have pressures: 3000LB,6000LB,9000LB.SS304 fittings are always used in chemical industries because of the excellent corrosion resistance.

Stainless steel tee has three types:BW,SW,THD.These are threaded tees in the picture.Threaded fittings have pressures:CL2000,CL3000,CL6000.

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.

Slip on flange is also called SO flange.This flange can slip onto the pipes and welded with the pipes.Shanghai Zhucheng is a forged flanges supplier who supply high quality flanges for years.

Stainless steel sockolet is belong to forged pipe fittings,the most used pressure is Class3000.In addition,there are also class6000,class9000 for the stainless steel sockolet.
