Advantages
Flanges are key components in connecting pipes and equipment, ensuring a tight seal between pipes, valves, pumps, and other equipment, ensuring safe and reliable fluid transport.
They are widely used in industries such as petrochemicals, machinery manufacturing, power generation, shipbuilding, metallurgy, and water supply systems, and are indispensable connectors in industrial piping systems.
As industrial equipment evolves toward high pressure, large diameters, and highly corrosive environments, flanges are increasingly demanding in terms of material strength, corrosion resistance, and sealing precision.
In this context, high-quality casting processes have become a core component of flange manufacturing. Leierwo provides flanges with a solid structural foundation and guaranteed performance.

Application of Casting in Flange Manufacturing
Our company specializes in the customized production of flange castings. We can provide various types of castings such as welding flanges, threaded flanges, butt welding flanges, loose flanges, etc. according to customer needs, which are suitable for different working conditions and industry applications.
Casting plays a vital role in flange manufacturing. Advanced casting processes enable the formation of complex structures in a single step, ensuring strength while reducing machining costs.
Common flange casting types include slip-on flanges, butt-weld flanges, threaded flanges, and blind flanges, all of which can be produced through sand casting or precision casting.
