Component Specifications

Definition
Flanges are protruding rims, edges, or collars used to connect pipes, valves, pumps, and other equipment to form a piping network. They provide a method for assembly, disassembly, and maintenance access. Gaskets are sealing materials placed between flange faces to create a pressure-tight seal by filling microscopic irregularities, preventing fluid or gas leakage under various pressure, temperature, and chemical conditions.
Working Principle
Flanges create a bolted joint connection between piping components, while gaskets utilize compression between flange faces to form a seal. When bolts are tightened, the gasket material deforms to fill surface imperfections, creating a barrier against media escape. The sealing effectiveness depends on proper bolt torque, gasket material properties, flange surface finish, and operating conditions.
Materials
Flanges: Carbon steel (ASTM A105, A350), stainless steel (ASTM A182 F304/316), alloy steel, ductile iron. Gaskets: Non-metallic (rubber, PTFE, graphite), semi-metallic (spiral wound, camprofile), metallic (ring type, flat).

Frequently Asked Questions

What are the main types of flange faces?

Raised face (RF), flat face (FF), ring-type joint (RTJ), and male-female configurations for different pressure and sealing requirements.

How often should gaskets be replaced?

During maintenance shutdowns, when leaks are detected, or when disassembling connections. Replacement frequency depends on operating conditions and gasket material.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
