Can a manhole gasket for a liquefied gas tank with a width smaller than the standard be used?

Thread Content

The operating pressure of the liquefied gas tank is less than or equal to 1.5 MPa. The sealing surface of the manhole flange is of the MFM type; according to the design requirements, the gasket to be used is of type HG20610, category B, with DN600 and PN2.5 specifications. The dimensions of the standard gasket are: D1=636 mm, D2=649 mm, D3=675 mm, D2-D1=13 mm, and D3-D1=39 mm； The dimensions of the new gaskets purchased are: D2-D1=16mm, D3-D1=20mm; the outer diameter remains the same for both the old and new gaskets! Can it be used?

It is best to use qualified, standard gaskets for pressure vessels
