GB/T 3087 is a key standard for seamless steel pipes in China's national standards.

GB/T 3087 is a key standard for seamless steel pipes in China's national standards. It specifies in detail the requirements for seamless steel pipes in terms of chemical composition, mechanical properties, inspection methods, marking, packaging and storage, thereby ensuring the production process The quality of steel pipes in. This standard is particularly applicable to low and medium pressure boilers, high pressure boilers, high pressure fertilizer equipment, heat exchangers, petroleum crackers and petroleum cracking equipment. The implementation of the GB/T 3087 standard is of great significance for ensuring the quality and reliability of steel pipes. It ensures the quality and service life of seamless steel pipes, further enhancing the safety and stability of industrial equipment and infrastructure. In addition, this standard has been widely recognized in the production, sales and use of seamless steel pipes at home and apoad.

The chemical composition of GB/T 3087 seamless steel pipe mainly includes carbon (C), silicon (Si), manganese (Mn), phosphorus (P), sulfur (S) and other elements. The content of each element is within a certain range. , to ensure the quality and performance of steel pipes. Specifically, the carbon content is usually between 0.17~0.23%, the silicon content is between 0.17~0.37%, and the manganese content is between 0.35~0.65%.

The production method of GB/T 3087 seamless steel pipe mainly includes the following key steps: material selection, blank preparation, piercing, rolling, heat treatment, and finishing.

GB/T 3087 seamless steel pipe has a series of remarkable characteristics, which make it widely used in many industrial fields.

1. Has excellent mechanical properties. Its high strength and toughness allow it to withstand greater pressure and impact without easily peaking or deforming.

2. Has excellent corrosion resistance. It is resistant to corrosion by a variety of chemicals, including acids, alkalis, salts, etc., thereby maintaining stable performance.

3. Has excellent weldability and processing performance. It can be connected through various welding processes, making it convenient for users to install and repair.
