It is necessary to verify that the pressure has been removed from the upper and downstream pipe of the ball valve before disassembling and decomposing.

First of all, stainless steel pipe fittings contain high pressure pipe fittings used in industry, also known as industrial pipe fittings.This kind of appearance is not so delicate, many are also used for outdoor, so the production process is relatively simple. After buying a long pipe, it is cut according to detailed data parameters, and then a series of machines, such as pipe bender, are used to make it into the desired shape. Such as 45 degrees, 90 degrees, 180 degrees and other specifications of elbow and tee, tee, size head, and even there will be some non-standard size.

Pneumatic ball valve is widely used in industrial automation, gas equipment and pipeline flow control system equipment.  Because of the pneumatic control ball valve simple structure, reliable quality, low price, good quality, many applications.  However, in the complex working conditions of process pipeline, once there are problems, it will cause a lot of problems

In ORDER to prevent the occurrence of intergranular erosion due to heating, the welding current should not be too sticky, 20% less than the carbon steel electrode, the arc should not be too long, the interlayer quick cooling to narrow welding pass is appropriate.

Stainless steel pipes, elbows, small pieces, etc. are suitable for this method, and the treatment effect is good. Because the treatment parts can be fully immersed in the pickling passivation solution, the surface reaction is complete, and the passivation film is dense and uniform. This method is suitable for continuous batch operation,

In recent years, in the heating system is widely used, GB stamping elbow as a new generation of heating special pipe is gradually becoming the mainstream goods in the heating market.Usually according to the group of fixed semi-finished products factory, site construction according to the pipeline weld grade welding, so it is also known as two half welding elbow.

Water supply and drainage pipeline engineering is the transmission and distribution of industrial water supply, drinking water and the collection, transmission and discharge of industrial wastewater, domestic sewage and rainwater pipe (channel) system engineering
