Third party inspections ensures the quality and integrity of a flange.At Regent Steel & Engineering Co., we encourage third party tests so that you can be assured about the quality of our duplex 2205 flanges.
Apart from this, we also have in-house tests which will ensure the chemical composition and mechanical properties of the material.We also identify defected and damaged flange and replace them with the perfect ones before supplying our clients.
The duplex stainless steel 2205 flange comes with different facing options like:
Duplex stainless steel 2205 flange
Alloy 2205 blind flange
Duplex steel 2205 slip on flange

Yes, it is possible to get hardness and impact testings on SAF 2205 weld neck flanges.These tests can be useful for assessing flange quality and mechanical properties, especially in high temperatures and pressures.
A compatible material should be used for the gasket with alloy 2205 blind flange or it may encounter galvanic corrosion.Common gasket materials are:
