Butt-welding pipe fittings - Part 4: Wrought austenitic and austenitic-ferritic (duplex) stainless steels with specific inspection requirements (Draft)
Also Known As:
This draft European Standard specifies the technical delivery requirements for seamless and welded butt-welding fittings (elbows, concentric and eccentric reducers, equal and reducing tees, caps) made of austenitic and austenitic-ferritic (duplex) stainless steel in two test-categories which are intended for pressure purposes at room temperature, at low temperature or at elevated temperatures, and for the transmission and distribution of fluids and gases. It specifies: - type A: butt-welding fittings with reduced pressure factor; - type B: butt-welding fittings for use at full service pressure; the steel grades;- the mechanical properties;- the dimensions and tolerances;- the requirements for inspection and testing;- the inspection documents;- the marking;- the handling and packaging.
