Steel Pipe/Tube

I. Materials and steel grades of seamless steel pipes and welded steel pipes Seamless steel pipes and welded steel pipes use different materials and steel grades according to their uses and requirements. Common ones include: 1. Seamless steel pipes Seamless steel pipes are usually used

Oil and gas line pipes are steel pipes specially used for transporting fluids such as oil and natural gas. As a key component for oil and gas transportation, it not only needs to withstand high pressure, corrosion, and low temperature, but also must meet the

The following are some commonly used grades and related introductions of carbon steel pipes in the world, classified according to common standards and countries: 1. United States (ASTM/ASME standard) ASTM A106 Purpose: Seamless carbon steel pipes widely used in high temperature and high pressure environments.

Coated steel pipe refers to a steel pipe with one or more layers of coating added to the surface of ordinary steel pipe to improve its performance. Coated steel pipe combines the strength of steel and the characteristics of surface coating and is widely used

Red plastic-coated fire fighting steel pipe is a steel pipe specially used in fire protection system. It has the characteristics of corrosion resistance, high temperature resistance and easy identification. It is widely used in automatic sprinkler fire extinguishing system, fire hydrant system, etc. The following

Seamless steel pipes are widely used in many industries such as petroleum, chemical industry, energy, and machinery manufacturing due to their high strength, good corrosion resistance, and strong pressure bearing capacity. In actual use, different industries and application scenarios have different requirements for the material

Hydraulic Honing Tube is a steel tube with high-precision inner hole and excellent surface quality. It is mainly used as a cylinder in hydraulic systems and pneumatic equipment. It uses special processing technology to ensure the roughness, dimensional accuracy and wear resistance of the inner

Welded steel pipe weld seam style and characteristics According to the weld seam form and processing technology, welded steel pipe is mainly divided into straight seam welded pipe, spiral welded pipe and other special weld seam forms (such as girth welding, spot welding). Different weld

Seamless steel pipes and welded pipes (including straight seam welded pipes and spiral welded pipes) have significant differences in manufacturing processes, performance, uses and costs. The following is a detailed comparison of the advantages and disadvantages of the two: Advantages of seamless steel pipe No

Seamless steel pipes have a variety of sizes and specifications. In order to meet the needs of different uses, there are usually multiple standard ranges in terms of outer diameter, wall thickness and length. 1. Common outer diameter range Small diameter seamless steel pipe: outer
