Questions regarding valves and their flange gaskets
Thread Content
I have a question: for example, if I specify the globe valve J41H-4.0 DN50, do I still need to indicate the models of the flange and gasket? Are there corresponding standards?
I want it. Steel pipe flanges, gaskets, and fasteners are included in HG20592
Of course, the model number needs to be mentioned; otherwise, how can the material be specified? Hehe
Provide the flange standards for valves as well as the materials and types of gaskets
The valve model only indicates whether it has a flange connection, a welded connection, etc., as well as the material of the valve. The type of flange and the type of sealing surface, along with the types of gaskets and bolts/nuts, should all be specified
Indeed, the valve model does not indicate the type and material of other components such as flanges and gaskets; HG20592 and petrochemical standard SH3405 are both available options
