The Hastelloy Pipe Weight Chart and dimensional specifications, chemical composition, mechanical properties, and ASTM B622 tolerances. It is meant to assist the engineers, fabricators, and industrial purchasers in making accurate calculations in very corrosive applications and high-temperature service. The Hastelloy pipes are highly applicable in chemical processing, pollution control, pharmaceuticals, and aerospace because of their outstanding resistance to corrosion by acids, chlorides, and oxidizing conditions. The elaborate weight chart of kg/m and mm allows rapid planning of materials in the extreme service conditions.
