Наслов на српском језику

Cevne spojnice za sučeono zavarivanje — Deo 4: Plastično prerađeni austenitni i austenitno-feritni (dupleks) nerđajući čelici sa posebnim zahtevima za ispitivanje

Наслов на енглеском језику

Butt-welding pipe fittings - Part 4: Wrought austenitic and austenitic-ferritic (duplex) stainless steels with specific inspection requirements

Апстракт на српском језику

Ovim evropskim standardom se utvrđuju tehnički zahtevi za isporuku bešavnih i šavnih sučeono zavarenih spojnih delova (kolena cevi, koncentričnih i ekscentričnih reducira, ravnih i suženih T-spojeva, naglavaka cevi), izrađenih od austenitnog i austenitno-feritnog (dupleks) nerđajućeg čelika, namenjenih za rad pod pritiskom, otpornih na koroziju na sobnoj temperaturi, na niskoj temperaturi, ili na povišenim temperaturama. U standardu su navedene: – vrste spojnih delova (fitinga); – tip A (videti 7.2); – tip B (videti 7.3); – vrste čelika; – mehaničke osobine; – mere i tolerancije; – zahtevi za kontrolisanje i ispitivanje; – dokumenta o kontrolisanju; – obeležavanje; – rukovanje i pakovanje.

Апстракт на енглеском језику

This document 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: a) type of fittings; 1) type A: butt-welding fittings with reduced pressure factor; 2) type B: butt-welding fittings for use at full service pressure; b) steel grades and their chemical compositions; c) mechanical properties; d) dimensions and tolerances; e) requirements for inspection and testing; f) inspection documents; g) marking; h) protection and packaging. NOTE The selection of the appropriate fitting (material, thickness) is the ultimate responsibility of the manufacturer of the pressure equipment (see European Legislation for Pressure Equipment). In the case of a harmonized supporting standard for materials, presumption of conformity to the ESRs is limited to technical data of materials in the standard and does not presume adequacy of the material to a specific item of equipment. Consequently, it is essential that the technical data stated in the material standard be assessed against the design requirements of this specific item of equipment to verify that the ESRs of the PED are satisfied.
