Spiral welded pipes are produced through a continuous welding process where a long strip of steel is formed into a helical shape and then welded along its seams. The production process can be broken into several steps:1. **Material Preparation**: High-quality steel strips or plates are used as the r

Concentricity: seamless manufacturing process at a temperature of 2200 °f punched a hole in the stainless steel billet, and at this temperature, tool steel becomes soft and stamped and drawing a spiral shape from Kong Zhongcheng come out. Such non-uniform wall thickness of the pipe and eccentric hig

Steel pipes are common materials in the construction and engineering fields, and 2205 duplex stainless steel pipes, as a special material, need to meet certain execution standards when used. 2205 duplex stainless steel pipe is duplex stainless steel with excellent corrosion resistance and mechanical

About raw materials:1. Steel pipe manufacturing and acceptance conform to the steel pipe pressure requirements and pipeline industry standards required by the project.2. The coating material meets the technical requirements of the project, and its performance complies with the provisions of the CJ/T

For steel pipes coated with epoxy resin inside and outside, first pre-treat the base pipe - grind the steel pipe (Advantages: Automatic spraying makes the coating on the inner and outer walls of the base material uniform and has good leveling properties. It meets CJ/T120-2008 standards and GB/ T5135

In the busy steel industry, threaded boiler steel pipes have become an indispensable and important pillar in many industrial fields with their unique structure and excellent performance. Today, let us enter the world of threaded boiler steel pipes and explore their unique charm and wide application

1. **Composition**: The steel should have a chemical composition that meets the desired specifications for strength, ductility, and corrosion resistance. This often includes controlling the carbon, manganese, phosphorus, sulfur, and other elemental contents.2. **Thickness**: The hot strip should be

To improve the welding quality of Longitudinally Submerged Arc Welded (LSAW) steel pipes, several key factors should be considered during the manufacturing process. LSAW pipes are typically constructed from plates that are welded along their length, and the quality of the weld is crucial for the pip

Seamless steel pipes are known for their excellent strength, durability, and resistance to pressure. They are widely used in various industries, including oil and gas, construction, and water transportation. One type of seamless steel pipe is the thick-walled uneven pipe, which refers to a pipe with

1. **Material Selection**: The choice of materials for casing and tubing cores is critical in ensuring their strength, corrosion resistance, and overall durability. Common materials include carbon steel, alloy steel, and stainless steel, selected based on the specific operating conditions and requir
