DIN 2413 Design of Steel Pressure Pipes

Scope and Field of Application DIN 2413 Part 1
This standard covers the design of straight steel pressure pipes with a circular cross-sectional shape and a ratio of outside to inside diameter for the following service conditions
A. Pipes subjected to perdominantly loading and rated for a temperature up to 120°C
B. Pipes subjected to perdominantly loading and rated for a temperature over 120°C
C. Pipes subjected to fatigue loading and rated for a temperature up to 120°C
The design of pipe fittings (e.g. flanges, branches) shall be carried out in compliance with the relevant DIN Standards and codes of practice.

Scope and Field of Application DIN 2413 Part 2
This standard covers the design of steel bends and bent pipes of circular cross section used in pressure pipelines and is to be applied in conjunction with DIN 2431 Part1.
The basis of design is to account for the fact that stresses on the inside of the bend are higher, and on the outside, lower, than those which act on a straight pipe sectioin of the same wall thickness and diameter.
