The purpose of steel pipe pile construction is to transfer the load of the superstructure to deeper, stronger soil layers or to compact weak soil layers to improve the bearing capacity and density of the foundation soil. Therefore, it is crucial to ensure the quality of steel pipe pile construction;

Austenitic stainless steel is softened through solution treatment. Generally, the stainless steel pipe is heated to approximately 950–1150℃ and held at that temperature for a period of time. This allows carbides and various alloying elements to fully and uniformly dissolve in the austenite. Then, it

GOST 8734-75 carbon seamless steel pipe is a standard specification for steel pipe. It is used in the transmission of oil and gas fluids. These seamless steel pipe exhibits excellent mechanical properties and resistance to corrosion. They are designed for use in oil and gas fluid transmission applic

GOST 8732-78 defines the specifications for hot-worked carbon seamless steel pipes widely used across industrial applications. This standard covers pipes manufactured based on outside diameter, wall thickness, and length, ensuring reliable performance under demanding operating conditions.Details of
