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

1. **Material Selection**: Choose high-quality steel that meets the specific requirements of the application. The material should have the appropriate chemical composition and mechanical properties to withstand galvanizing and meet the desired performance criteria.2. **Galvanizing Process**: Select

(1) When we use oil casing to transport water, we should ensure that the quality of the water must be qualified when using it, and the quality of the water must be qualified when using it, and it must be discharged when discharged. Implement cleaning and dispensing. During use, it is necessary to st

304 stainless steel is an austenitic stainless steel and is in principle a non-magnetic product. However, in actual production and use, it may be found that 304 stainless steel has a certain weak magnetism. This is mainly due to the following factors:1. Phase transformation during processing and for
