Is it feasible to change the DN300 PN25 RF sealing surface to the FM/M surface? Because it is an INCONEL special material and is very expensive. I want to process it and use it. According to "HG/T20592~20635-2009"_If the "Steel Pipe Flange Gaskets and Fasteners" standard is met, it should be possible to change it. Please give me some guidance.
I don’t know if you can understand it, but measure your flange according to the dimensions above and see if it can be changed.
I am also looking at this standard. What the supplier provides is DIN EN1092-1 German standard. I don’t know if it is consistent.
DIN EN1092 and HG 20592 are different standards, and the valve length and flange parameters are different.
It can be modified, but it will be wobbly during processing. The flange holes are all drilled. .
Is it because the seal cannot be sealed and the sealing structure needs to be changed? Change low pressure to high pressure? There is definitely a deviation from the comparison standard, but if you have two 25kg RF surface flanges, if the calculated pressure strength allows, you can change the convex and concave surfaces to increase sealing. If the bolt strength is not enough, you can add a clamp outside the flange to increase the tightening force.
