What is machining carbon steel flat face flange?

The sealing surface of machining carbon steel flat face flange is smooth plane, and sometimes there are two or three triangular concentric circular grooves on the sealing surface called water line (sealing line or anti-slip tank) suitable for flat welding flange includes various non-metallic flat gaskets, covering pad, metal bonding pad. With winding gasket (can have both inner or outer ring). loop. Simple structure, easy processing, anti-corrosion lining construction convenience, can reach the nominal pressure force.

Product Advantages
SJ-Machinery Engineering enhances the design for efficient mass production without requiring post-processing. Featuring a robust design, it ensures peak functionality at the most competitive production cost. Simultaneously casting an oil channel in the valve stem pocket optimizes weight reduction through a 'Near Net Shape' approach. This leads to reduced inertia in the valve mechanism, contributing to fuel savings. The component is cast in hardened steel without the need for additional post-processing, resulting in significant cost efficiencies.
