Nine Piping Solutions is a known supplier, distributor and stockist of Alloy Steel P9 Forged Threaded Pipe Fittings, which should be machined in the annealed condition using surface speeds. The parts should then be Alloy Steel P9 Forged Threaded Elbow Fittings which is generally considered to be weldable by the common fusion and resistance techniques. For maximum corrosion resistance to chemical environments, it is essential that the surface of Alloy Steel P9 Forged Threaded Tee Fittings be free of all heat tint or oxide formed during annealing or hot working.
All surfaces of Alloy Steel P9 must be ground or polished to remove any traces of oxide and surface decarburization. Alloy Steel P9 Forged Threaded Cap Fittings useful for storing and handling acetic acid, especially in solutions where it is combined with formic acid and when aeration is not present (oxygen helps protect stainless steel under such conditions), though it provides the greatest level of resistance to corrosion.
