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

Stainless steel pipe fittings, especially tee, elbow and size head are more and more common in the process of pipeline construction. This is mainly because it has the characteristics of good forming, strong pressure resistance and simple welding form to ensure the bearing capacity of the pipeline. 

One of the advantages of stainless steel flange manufacturers is a complete range.  In different brands of stainless steel flange manufacturers, no matter what materials of stainless steel flange.  First of all, do not say how the quality of these stainless steel flange products, stainless steel flange types are also enough to attract customers' attention.Whether broken bridge aluminum or compound materials, even if you want to environmentally friendly stainless steel flange products, can be purchased. All kinds of individual needs of today's consumers can be met
