Alloy pipes are pipes made of alloy steel (such as low-alloy high-strength steel, alloy structural steel, etc.). They are widely used in multiple industrial fields due to their excellent mechanical properties (strength, toughness), corrosion resistance, high temperature resistance, high pressure resistance and other characteristics.
The core purpose of alloy pipes is to transport fluids or bear structures under harsh working conditions such as high temperature, high pressure, and severe corrosion. In essence, it uses its mechanical properties and weather resistance that are superior to ordinary steel pipes to solve the problem that ordinary pipes “cannot withstand the pressure and cannot be used for long.”
