This article provides for evaluating the WN flange loads, taking into account the internal pressure together with the external loads (forces and bending moments) acting on the WN flange. The loads exerted on the flange that are included in the …
The flange face surface finish has an influence on a safety and tight flange connection. For standard requirements, the design of the flange surface determines the required roughness. This is taken into account in the standards for flanges (see the …
“Gasket blowout” is a term used to describe the sudden and catastrophic failure of a gasket. Blowout usually occurs when the applied pressure exceeds the physical strength of a gasket. bA blowout condition creates a hazard for personnel, equipment, and …
The gasket characteristics are determined in a defined procedure under laboratory conditions under idealised test conditions. This test is based on the corresponding compression, leakage and relaxation tests in accordance with EN 13555. The gasket characteristics must adequately describe the …
To confirm the safe function of a flange connection, proof of tightness and proof of strength must be provided. In the case of tightness verifications, proof must be provided that the design of the flange, gasket and bolt system ensures …
Compatible hydrogen piping steel is coming into focus in the context of the increasing importance of hydrogen for energy applications, particularly with regard to hydrogen embrittlement (HE). Carbon steels with higher strengths are increasingly coming into focus for the storage …
