1) The type, specification, and quality of stainless steel pipes, components, and welding materials must meet the design requirements and specifications.2) The positions of supports, hangers, and brackets should be correct, flat, and firm, and the backing plate in contact with the pipe should be mad

Choose to purchase stainless steel pipes 1. Identify whether the material "304" is stamped on the surface of the pipe, and ask for the quality certificate and quality assurance certificate of the stainless steel pipe manufacturer.Choose to purchase stainless steel tube 2. Test with the acid reagent.

The installation method of stainless steel pipes is the same as that of ordinary carbon steel, and some processes have the following process requirements.1 Stainless steel materials should not be in direct contact with other metals when being lifted and should be padded with non-metallic materials s

All metals react with oxygen in the atmosphere to form an oxide film on the surface. Unfortunately, the iron oxide that forms on plain carbon steel continues to oxidize, allowing the rust to grow and eventually form holes. Carbon steel surfaces can be secured with paint or with oxidation-resistant m

Welded steel pipes are mainly divided into three processes: electric resistance welding (ERW), spiral submerged arc welding (SSAW), and straight seam submerged arc welding (LSAW). The welded pipes produced by these three processes have their positioning and advantages in the application field due to

The biggest difference between electric resistance welding (Electric Resistance Welding, ERW for short) and seamless steel pipe is that ERW has a weld seam, which is also the key to the quality of ERW steel pipe. Modern ERW steel pipe production technology and equipment, due to the unremitting effor

1. Shoddy steel product is prone to folding. Folding is a variety of fold lines formed on the surface of the steel, and this defect often runs through the longitudinal direction of the entire product. The reason for the folding is that the counterfeit and inferior manufacturers pursue high efficienc

What are the production methods of steel bending pipe? One is to place rubber in the pipe and compress it with a punch above to make the pipe protrude; the other method is hydraulic bulging, filling the middle of the pipe with liquid, and the pressure of the liquid will bulge the pipe Into the requi

1. Cleaning method: When cleaning the surface of the stainless steel pipe, care must be taken not to scratch the surface. Avoid using bleaching ingredients and abrasive washing liquid, steel wire balls, grinding tools, etc. To remove the washing liquid, rinse with clean water at the end of the washi
