What is a 254 SMO Tee?

A 254 SMO Tee is a super-austenitic stainless-steel butt-weld fitting used to create a branch connection in piping systems exposed to demanding corrosive environments.

254 SMO is a super-austenitic stainless steel containing high levels of chromium, molybdenum and nitrogen.

Its high alloy content provides excellent resistance to pitting, crevice corrosion and chloride stress corrosion cracking in suitable service conditions.

ASTM A403 / ASME SA403 can be applicable to wrought austenitic stainless-steel fittings, subject to the exact product requirements.

Yes. Material Test Certificates, inspection reports and relevant quality documents can be supplied according to customer and project requirements.

Testing can include chemical analysis, mechanical testing, dimensional inspection, visual inspection, hydrostatic testing and other specified tests.
