Mechanical property testing methods are mainly divided into two categories: tensile testing and hardness testing.1. Tensile testing involves preparing a sample from the spiral welded steel pipe and stretching it to fracture on a tensile testing machine. One or more mechanical properties are then mea

With the continuous development of industrial technology, the steel industry plays a vital role in modern society. Among numerous steel products, precision hydraulic seamless steel pipes have attracted much attention due to their unique characteristics and wide range of applications.1. Overview of P

The connection quality of industrial pipeline systems directly affects production safety and operational efficiency, and leakage problems at pipeline connections have long plagued multiple industries such as petrochemicals, power, and water treatment. How to achieve long-term sealing and corrosion r

In recent years, China's plastic-coated steel pipe manufacturing industry has developed rapidly, and plastic-coated steel pipes have gained recognition in various industries. Because plastic-coated steel pipes possess both the high strength of steel pipes and the chemical corrosion resistance of eng

The production process of straight seam steel pipes is relatively simple, mainly involving high-frequency welded straight seam pipes and submerged arc welded straight seam pipes. Straight seam steel pipes have high production efficiency, low cost, and rapid development. Spiral steel pipes generally
