Manhole covers can be classified into protruding and recessed types based on whether they protrude above the opening surface after installation.

Before manufacturing stainless steel pipe fittings, the raw materials must first be pre-treated.

When purchasing, check the product testing report or material certificate, or perform a magnet test (304 stainless steel has extremely weak magnetism)

304 stainless steel contains 18% chromium and 8% nickel, forming a dense passivation film in oxidizing environments, effectively resisting corrosion f

Stainless steel pipe fittings are industrial accessories used to connect pipes of different materials.

Flanges can be made of either steel or stainless steel, depending on the application.

Connection is not easily deformed, good sealing effect, widely used, suitable for pipelines with large temperature or pressure fluctuations, or high-t

When applying the base weld, always use J506 welding rods for manual surfacing and employ low current welding. Strictly follow the welding procedure.

Flange connection involves fixing two pipes, fittings, or equipment to separate flanges, placing a gasket between the two flanges, and then tightening

A flange, also called a flange plate or flange, is a component used to connect shafts, specifically for connecting pipe ends. Flanges are also used on
