The SS grade instrumentation headers offer great resistance to intergranular attacks and crevice corrosion. Alloy 304L is the lower carbon version of 304 grades developed for providing resistance to grain boundary precipitation. These instrumentation air headers offer pitting corrosion resistance in the most severe environments.

Each and every Stainless Steel 304L Instrument Air Header is factory tested under the norms of testing procedures. Different norms are taken in the account under the international standards. The tests performed on the instrumentation headers are compression test, hardness test, PMI test, intergranular corrosion test, mechanical test, pitting corrosion test, destructive test, crushing test, and non-destructive test. Other tests are pressure test, temperature test, tensile test, radiographic test, ultrasonic test, and more.

We provide these instrumentation air headers are delivered in the wooden boxes, pallets, cartons, and cases with the additional support of thin film of plastic that protects outer contamination.
