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 carbon and alloy 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;
type A: Butt-welding fittings with reduced pressure factor;
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.
What is BS EN 10253‑2 about?
BS EN 10253‑2 is the second part of a series of documents on butt-welding pipe fittings.
BS EN 10253‑2 specifies the technical delivery requirements for seamless and welded butt-welding fittings made of carbon and alloy steel in two test categories which are intended for pressure purposes at room temperature, at low temperature, or elevated temperatures, and for the transmission and distribution of fluids and gases.
BS EN 10253‑2 specifies the type of fittings, type A: Butt-welding fittings with reduced pressure factor, type B: Butt-welding fittings for use at full-service pressure, steel grades and their chemical compositions, mechanical properties, dimensions and tolerances, requirements for inspection, and testing, inspection documents, marking, protection and packaging.
Who is BS EN 10253‑2 for?
BS EN 10253‑2 on Butt-welding pipe fittings is relevant to:
- Welders/ fabricators
- Quality controllers
- Non-destructive testing (NDT) personnel
Why should you use BS EN 10253‑2?
A butt weld is one of the simplest and most versatile types of weld joint.
BS EN 10253‑2 provides detailed information on welding, finished weld requirement, heat treatment after welding, heat treatment condition, technical requirements, chemical composition, mechanical properties according to temperature, strength impact properties form of fittings.
BS EN 10253‑2 provides guidance to the user to do accurate butt-welding on non-alloy and ferritic alloy steels. Information on the type of inspection, tensile test, weld bend test, impact test, visual testing (VT), Non-destructive testing of the weld is given in BS EN 10253‑2 which helps the user to inspect the weld joint and maintain the quality of the weld. With BS EN 10253‑2 you can be ensured that the products consistently meet and exceed quality assurance targets.
What’s changed since the last update?
BS EN 10253‑2:2021 supersedes BS EN 10253‑2:2007, which is withdrawn.
The main changes compared to the previous edition are listed below:
- Document technically and editorially revised
- Revision of chemical composition and steel-grades
- Revision of permissible deviations of the product analysis from specified limits on cast analysis, mechanical properties.
- Addition of creep rupture strength values
- Updated inspection, tests, and pressure factors
