Raaj Sagar Steel is an Indian steel company, supplying quality steel to businesses in Mumbai India and across Gulf Countries, Middle East, Europe. We have a number of distribution centres across the state, which stock a range of quality steel supplies including steel tube & pipe, fasteners, round bar products, steel roofing products and steel tubing products.
The specification covers seamless and straight-seam welded ferritic/austenitic steel pipe for general corrosive service, with particular emphasis on resistance to stress corrosion cracking. The pipe shall be made by the seamless or an automatic welding process, with no addition of filler metal in the welding operation. Heat analysis shall be made to determine the percentages of the elements specified. Tension tests, hardening tests, flattening tests, hydrostatic tests and nondestructive electric tests shall be made to conform to the specified requirements.
