Factory Direct Sale SS304 DN125 PN16 Ductile Iron Pipe Flange Adaptor
Adapter size and shape: The flange adapter must precisely match the size and shape of the flange to be connected to ensure a proper fit and seal.
Adapter material: The material of the flange adapter should be strong enough to withstand the expected pressure and temperature, while also having good sealing properties.
Common materials include carbon steel, stainless steel.
Bolts and gaskets: Flange adapters are usually equipped with bolts and gaskets.
Bolts are used to fix the flanges in place, while gaskets are used to fill the gaps between flanges to prevent fluid or gas leakage.
Flange adapter consists of loose fitting expansion joint and limit short pipe.
It is mainly used to absorb axial displacement within the permissible displacement range and loose pipe connection under axial pressure and thrust.
