1. Tolerances on dimension according to EN 10253-1

1) All diameters of EN 10253-1 pipe fittings shall be measured at the welding ends of the fittings. The tolerance is ±1% or ±0.5 mm whichever is the greater.

2) In order to ensure the flow-way area through the fitting is not excessively reduced, the internal diameter(not applicable to dished ends and caps) shall be greater than 80% of the theoretical internal diameter(ID), as calculated by: ID = OD - 2T.

3) Tolerances for ovality are:

at the welding ends: 2%;

on the body for elbows and return bends: 4%.

The ovality(Ov) shall be calculated by:

Ov = 200 * (Dmax - Dmin) / (Dmax + Dmin) in %.

Dmax: maximum measured diameter in one section.

Dmin: minimum measured diameter in one section.

4) Wall thickness tolerances

 *D: Outside diameter at the welding end. T: Wall thickness.

 *The minus tolerance also applies to the body of the fitting.

5) Tolerances on specific dimensions

114.3<D≤219.1±2±7±7±7±3
219.1<D≤406.4±3±7±10±7±5

 *D: outside diameter;

 *F: distance from the axis of the center line to the face of the branch outlet of equal tee.

 *G: distance from the axis of the center line to the face of the branch outlet of reducing tee.

 *H: Face to center-line distance for 45°.

 *B: Face to top distance for 180° return bends.

 *C: Center to center distance for 180° return bends.

 *K: height of dished ends or caps.

 *L: Face to face length of reducers(both concentric & eccentric).

6) Tolerances on the form of fittings

The tolerance on the form of each type of fitting Q = 1% of the outside diameter(D) or 1 mm, whichever is greater. See the figure illustrated below.

2. End finish of EN 10253-1 butt welding pipe fittings

According to DIN EN 10253-1,
for wall thickness T < 3.0 mm, the ends may be plain or slightly chamfered.
for wall thickness T ≥ 3.0 mm, the ends shall be bevelled with an angle of 30 degrees to 35 degrees with a face of 1.6 mm ± 0.8 mm.
The welding ends of EN 10253-1 pipe fittings shall be free from harmful blurs.
Specially, the ends of dished ends with diameter ≥ 159 mm shall be bevelled with an angle of  30 degrees to 35 degrees with a face of 1.6 mm ± 0.8 mm.
