Scope

This Japanese Industrial Standard specifies the arc welded carbon steel pipes (hereafter referred to as “pipes”) used for piping for steam, water, gas, air, etc. of comparatively low working pressure.

Normative references

The following standards contain provisions which, through reference in this text, constitute provisions of this standard. The most recent editions of the standards (including amendments) indicated below shall be applied.

3 Grade and designation

The pipes shall be classified into one grade and its letter symbol shall be as given in table 1.

Method of manufacture

The method of manufacture of pipe shall be as follows:

a)The pipes shall be manufactured by spiral seam or straight seam welding. In either case, the internal and external surfaces of the pipe shall be automatic submerged arc welded in a butt joint.

b)The pipes shall be either as welded or as cold-expanded after welding, and, as a rule, should not be subjected to heat treatment.

c)Both ends of the pipe shall be finished plain ended or bevel ended(1).

Note (I) Unless otherwise specified, the shape of the bevel end shall be as shown in figure 1.

Application:Used for piping for the steam,water,gas,air,etc.

Notes a)In this case,either the actually measured value of circumfential length or outside diameter and the

circumferential length or outside diameter obtained by conversion thereof shall be used.

The mutual conversion of the outside diametre and the circumferential length shall be made by the following

equation.

D=l/π
