Steel butt-welding pipe fittings

Caps

Formstücke zum Einschweißen; Kappen; Maße

Supersedes June 1964 edition.

In keeping with current practice in standards published by the International Organization for Standardization (ISO), a comma has been used throughout as the decimal marker.

Dimensions in mm

1 Field of application

This standard specifies steel caps that are intended to be butt welded to pipes and that are rated for the same internal pressure as pipes having a wall thickness as specified in table 1 (cf. clause 4).

2 Dimensions and designation

Dished portion

Cylindrical portion

r₁ ≈ 0,8 d_a

r₂ ≈ 0,154 d_a

s₂ ≥ s₁

Designation of a cap in accordance with this standard, having an outside diameter, d_a, equal to 88,9 mm and a wall thickness, s₁, equal to 2,3 mm, made from material belonging to material group C as in DIN 2609 (C):

Cap DIN 2617 – 88,9 × 2,3 – C

1) s₂ shall be greater than or equal to s₁ (cf. footnote 2).

2) In the case of wall thickness series 1, for nominal sizes from DN 300 to DN 1200, the values specified for s₂ are minimum values.

3 Tolerances

Table 2. Lower limit deviations for wall thickness
(See DIN 2609 for upper limit deviations.)

Nominal size DN	Wall thickness	Lower limit deviation
Up to 600	All sizes	- 12,5 %
Above 600	Up to 10	- 0,35 mm
Above 600	Above 10	- 0,50 mm

Table 3. Limit deviations for dimension h

Nominal size DN	Limit deviations for dimension h
15 to 100	± 4
125 to 600	± 7
700 to 1000	± 10

4 Design assumptions

The wall thickness of caps has been designed so that the caps are capable of accommodating the same pressure as the connecting pipe having a wall thickness, s₁, as in table 2, in accordance with the AD-Merkblatt (AD Instruction sheet) B 3. The values specified for h include the height of a cylindrical portion equal to at least 3 × s₁. Design has also been based on the following assumptions:

a) lower limit deviations for pipe and cap dimensions, as given in table 2;

b) identical material;

c) identical outside diameter;

d) no allowance for corrosion;

e) the cap is used at full service pressure.

5 Other wall thicknesses

Caps with wall thicknesses other than those specified in table 1, which lie between two sizes specified, may also be ordered in accordance with this standard.
