From the perspective of metallography, because stainless steel precision steel pipes contain a high amount of chromium, chromium forms a very thin chromium film on the surface. This film isolates the oxygen that invades the steel, thus playing a role in corrosion resistance. For stainless steel pipe

It is well known that the performance of thick-walled stainless steel pipes will be better after heat treatment, and it will be more in line with the performance requirements of mechanical parts. However, during the heat treatment process, metal materials will have problems such as deformation. The

Five connection structures between steel tubes and tube sheets of heat exchangers. The connection between steel tubes and tube sheets is a relatively important structural part of the design of shell and tube heat exchangers. It not only requires a large amount of processing work but also requires th

1. CostBecause there is one less process than cold-rolled substrate, the production cost of hot-rolled substrate galvanizing is lower than that of cold-rolled substrate, mainly the annealing cost and cold-rolling rolling cost, and the other processes are similar. 2. Quality performanceBecause the ho

Spiral welded steel pipe is a common pipeline manufacturing process, where DN400 refers to the nominal diameter of the pipe as 400 mm. This type of steel pipe has a wide range of applications in engineering and construction. Next, we will delve into the advantages of spiral welded steel pipe DN400 a

A carbon steel composite steel pipe is an innovative pipe that combines carbon steel and other materials. Its advent has brought a revolution to the steel industry. Traditional carbon steel pipes have limitations in some areas, such as poor corrosion resistance and insufficient strength. The emergen

SC welded steel pipe, a very tough steel pipe, is favored by the industry.SC welded steel pipe, full name Submerged Arc Welding Welded Steel Pipe, is a steel pipe manufactured by submerged arc welding process. It is made of steel plate through a series of processes and has excellent performance and

Definition of basic concepts:Plastic-coated steel pipe, intuitively speaking, is an innovative material that achieves corrosion resistance, wear resistance, and rust resistance by applying a plastic coating on the surface of the steel pipe. In contrast, plastic-lined steel pipe adopts an internal st

In the steel industry, galvanized steel pipes are a common material. After hot-dip galvanizing, they are corrosion-resistant and wear-resistant and are widely used in construction, manufacturing, and other fields. Special galvanized steel pipes refer to a type of galvanized steel pipes customized ac

First, the feasible fields for welded steel pipes to replace seamless steel pipes1. At present, welded pipes can replace seamless steel pipes in more and more fields. First, because the thickness of welded pipes is more uniform, they can play a role in decorative pipes, and can also make up for the
