ASME Carbon steel female threaded coupling with Powder metallurgy coating.
The inner coupling is used for the link between the pipes, and the equal diameter is connected.
Other names: hexagonal inner coupling, outer thread coupling,etc.
Inner joint purpose: used to connect two internal threaded pipe fittings or valves with the same nominal diameter.
Powder metallurgy is a process technology for preparing metal powder or using metal powder (or a mixture of metal powder and non-metal powder) as raw materials, forming and sintering, to produce metal materials, composite materials and various types of products.
Powder metallurgy has unique chemical composition and mechanical and physical properties, and these properties cannot be obtained by traditional melting and casting methods. The use of powder metallurgy technology can directly produce porous, semi-dense or fully dense materials and products, such as oil-bearing bearings, gears, cams, guide rods, cutting tools, etc., which is a rare cutting process.
Powder metallurgy technology can minimize the segregation of alloy components and eliminate coarse and uneven casting structures. In the preparation of high-performance rare earth permanent magnet materials, rare earth hydrogen storage materials, rare earth luminescent materials, rare earth catalysts, high temperature superconducting materials, new metal materials (such as Al-Li alloys, heat-resistant Al alloys, super alloys, powder corrosion-resistant stainless steel, powder High-speed steel, intermetallic compounds, high-temperature structural materials, etc.) play an important role.
