ASTM A182 is standard specification for socket weld fittings, threaded fittings and forged steel flanges, the common used grades are F11, F22, F91, F304/304L and F316/316L in various industries.
Shanghai Zhucheng Pipe Fittings Manufacturing Co Ltd supplied various pipe fittings & flanges for North American, South American, Europe, Mid East, Southeast Asia, Austiralia and African market.
STANDARD
ASTM A182 specification covers forged low alloy and stainless steel piping components for use in pressure systems. Included are flanges, fittings, Valves, and similar parts to specified dimensions or to dimensional standards.
Several grades of low alloy steels and ferritic, martensitic, austenitic, and ferritic-austenitic stainless steels are included in this specification. Selection will depend upon design and service requirements.

CHEMICAL COMPOSITION & MECHNICAL PROPERTIES
ADVANTAGE
(1) Good corrosion-resistant performance that easily superior to other entry-level metals
(2) Withstand great pressure. It helps to ensure that deformation does not endange the system.
DISADVANTAGE
(1) Difficult to use for welding, so there are limited used in construction.
(2) More expensive than alternatives.
