What is A312 TP904L?

904L pipe to A312/SA312 for general corrosive service. Strength guide: per SA-312 / PO for 904L — confirm edition.

Typical applications

Sulphuric / phosphoric acid piping
Seawater and chloride process lines
Pulp & paper and chemical scrubber systems

Selection guidance

Use 904L when 316L/317L are inadequate but full nickel alloy is not justified. Compare with 254 SMO / 6Mo and duplex/super duplex on PREN and cost.
