Types of Flange Sealing Material

Flange Sealing Gasket
A flange sealing gasket is a mechanical seal placed between two flanges in a piping system to prevent the leakage of fluids or gases. These gaskets are designed to create a tight seal between the flanged surfaces, ensuring that process fluids like water, oil, or chemicals don't escape.

Flexible Rubber Sheet Material
Flexible rubber sheet material is a flat, bendable sheet made from rubber, either natural or synthetic, that offers a range of properties like elasticity, resilience, and durability. These sheets are commonly used in applications like sealing, insulation, shock absorption, and vibration damping.

Reliable Non-Asbestos Seal Sheet
A Non-Asbestos Seal Sheet is a gasket or sealing material that replaces asbestos gaskets while offering similar sealing performance and resistance to heat and chemicals. These materials are compressed to form a strong and durable gasket that can withstand high temperatures and pressures.

Flange Sealing Material: Surface Finish

Surface finishing is crucial to forming a successful physical barrier between two flanges. The finish can be either machined or pressed onto the gasket.

It contains grooves or channels. If the finish is too fine or shallow, it will lack the grip needed to maintain integrity.

The too-deep finish creates complications in forming a seal due to an excessive bolt load on large flanges.
