EN10253-2 13CRMO4-5 BUTT WELD CARBON STEEL PIPE FITTINGS

EN10253-2 13CRMO4-5 BUTT WELD CARBON STEEL PIPE FITTINGS​

13CrMo4-5 is a heat-resistant special structural steel. It is mainly used in boiler and apparatus construction. The material is suitable for temperatures up to 550°C. 13CrMo4-5 can be welded without problems.

1 Scope
1.1 This part of EN 10253 specifies the technical delivery requirements for seamless and welded buttwelding fittings (elbows, concentric and eccentric reducers, equal and reducing tees, caps) made of austenitic and austenitic–ferritic (duplex) stainless steel without specific inspection requirements.
It specifies:

• steel grades;
• mechanical properties;
• dimensions and tolerances;
• requirements for inspection and testing;
• inspection documents;
• marking;
• handling and packaging.

1.2 Limitation of use
The allowed pressures and temperatures are the responsibility of the customer according to the state of the art and in application of the ety coefficients in the application regulations, codes and standards. In common, joint coefficient is used in the calculation of the thicknesses of components which include one or several butt welds, other than circumferential:
for equipment subject to random non-destructive testing: 0,85;
for equipment not subject to non-destructive testing other than visual inspection: 0,7.
1.3 Unless otherwise specified in this part of EN 10253 the general technical delivery requirements in EN 10021 apply.

The En 10253-2 Fittings has certain technical delivery requirements such as the types, markings, the steel grade, the package, the dimensions and so on. It is easy for the customer to know the details by the specification. The Bend En 10253-2-type A is similar to the type A elbow but the bend is longer, eliminating the sudden pressure on the walls. The DIN En 10253 2 Type B Elbow is short and it can excerpt much pressure at turns. However, our BS En 10253-2 Type B Elbow and other fittings are made up of superior quality and undergo careful testing so that our customers can get the best products.
