Due to its excellent performance, stainless steel welded pipes are widely used in electric heating pipes, radiators, petrochemicals, and various industrial stainless steel pipe industries. What are its specific applications?Stainless steel welded pipes are now mainly used in industrial machinery, au

Welded steel pipes are tubular products made from flat plates, called skeletons, which are formed, bent and prepared for welding. The production process of welded steel pipe is simple, with high production efficiency , large variety of specifications and the less equipment .With the rapid developmen

At all stages of the heat treatment process, the temperature must be accurately monitored and recorded by a thermocouple or other suitable, approved method, to guarantee that the temperatures specified in the WPS are adhered to during the welding process. When necessary these temperatures must be re

Steel pipe should be welded, except for joints which need to be taken apart for service, which will be flanged. It is essential that welding is carried out by competent craftsmen and is subject to stringent inspection.Flanges for ammonia (and preferably, also, for other refrigerants) must be of the

Hot dipped galv.seamless steel pipe is a steel pipe coated with a layer of zinc on the surface. The molten metal reacts with the substrate to form an alloy layer, so that the coating and the substrate are firmly bonded, and the thickness of the coating is uniform. It also has good corrosion resistance due to its galvanized coating.

Steel pipesSteel pipes to BS 1387 are normally specified in the nominal bore sizes given in Table 1. Finishes can be black or galvanised, the latter being preferred for corrosion resistance.
