Boiler A178 Pipes
SA 178 A specification covers standards for electric-resistance welded pipes with minimum wall-thickness made of carbon steel and carbon-manganese steel for its application in boiler tubes, boiler flues, superheater flues, and safe ends. The steel Grades in this type are denoted as A (low-carbon steel), C (medium-carbon steel), or D (carbon-manganese steel). All pipes of FASTWELL’s inventory are submitted to heat treatment after welding, and cooling.
The steel conforms to stated compositions of carbon, manganese, phosphorus, sulphur, and silicon by PED approved, ISO certified , NORSOK approved, NACE approved, the American Petroleum Institute specification, ISO 17025, ISO 9001:2008, 18001:2007, 14001:2004, Govt. of India recognized Export House.
Applications of A 178 A boiler pipe are in small factories and industrial processes, For home heating systems, Chemical processing divisions, refining units and Pulp and Paper manufacturing plants. The chemical composition includes Carbon: 0.06-0.18, Manganese: 0.27-0.63, Potassium: 0.035 and Sulfur: 0.035
