MANUFACTURER AND STOCKIST OF THREADED PIPE FITTINGS IN MAHARASHTRA
buttweld-elbow-(180°)
Buttweld fittings are designed and manufactured to standards which demand a bursting strength equal to or greater than that of Seamless Pipe of the same material specification, nominal diameter and wall thickness, and their allowable working pressures are equal to those shown for pipe in the OneSteel pipe catalogue. Maximum allowable working pressures for: CARBON STEEL FITTINGS: Equal to seamless pipes to ASTM A106, (Grade B unless otherwise specified). HIGH TEMPERATURE (Ferritic Alloy): Fittings (Grades WP5, WP11 etc), are equal to seamless pipes to ASTM A335 of similar grade (P5, P11, etc). LOW TEMPERATURE: Fittings (Grade WPL6-ASTM A420) are equal to seamless pipes to Grade 6 - ASTM A333. STAINLESS STEEL: Fittings (Grades 304 and 316, also 304L and 316L) are equal to stainless steel pipes to ASTM A312 of equal grade and schedule. NB: Stainless Steel Fittings in Schedule 10S and 5S are not designed for applications where pressure is a prime consideration, and the relevant standard, MSS SP43 establishes the working pressures substantially lower than those yielded by the application of the basic formula.
