What is a flange gasket used for?
Flange gaskets are designed to seal the space between two sections of pipe. Most pipes, of course, are joined at a flanged surface. The surface where two pipes join isn’t smooth or otherwise flat. Rather, it’s flanged, meaning it flares out.
What is the difference between flange and gasket?
Flange gaskets are used to create a static seal between two flanges faces, at various operating conditions, with varied pressure and temperature ratings. A gaskets fills the microscopic spaces and irregularities of the flange faces, and then it forms a seal that is designed to keep liquids and gases.
Do HDPE flanges need gaskets?
Some bolted connections can be made with no gasket at all, because the HDPE surfaces will seal against each other in many applications. However, a gasket is usually recommended for connections to metal flanges, and most customers prefer a gasket in all bolted joints.
What thickness gasket do I need?
On the downside, thinner gaskets will not seal as many flange irregularities as thicker gaskets, and require flatter flanges. The most commonly used thicknesses for Standard Flange gaskets are 1/16″ and 1/8″.

What is HDPE flange?
HDPE Pipe flanges are used to connect the polyethylene pipe to other types of pipes and valves.The flanges are sealed with gaskets.This type of connection is a reliable and reliable connection, which is, of course, more expensive than the rest of the connections.
Does HDPE need thrust blocks?
No. HDPE pipe and fittings joined by heat fusion are self-restrained in all applications, and therefore do not require thrust blocks, provided the entire system is fused. Thrust blocks may be required in cases where special gasketed mechanical fittings are used.
What are the types of flange gaskets?
Types of flange gaskets: Standard pipe flange gasket line includes two basic styles: Ring Type and; Full Face; Both ring type and full face pipe flange gaskets are available in both low and high pressure options.
What gasket thickness should I use in my flange system?
Apply a continuous bead of silicone to the mating surface.
