1.Scope

This Japanese Industrial Standard specifies the carbon steel pipes, hereinafter referred to as the“pipes”, used for the piping for conveying steam, water, oil, gas, air, etc. At comparatively low working pressures.

Remark: The units and numerical values given in { } in this Standard are based on the International System of Units (SI) and are appended for informative reference.

Further, the traditional units accompanied by numerical values in this Standard shall be converted to the SI units and numerical values on Jan. 1st, 1991.

2.Grade and Designation

The pipe shall be classified into one grade and its letter symbol shall be as given in Table 1, and subdivided into black pipes and galvanized ones according to nonexistence of existence of zinc-coated layers.

Remark: Where it is necessary to identify the galvanized pipe by the letter symbol on the drawing and other documents, “-ZN” shall be suffixed to the letter symbol of the grade. This notation, however, shall not be applied to the product itself.

Mechanical properties

Uniformity of Zinc Coating

The galvanized pipe shall be tested by 10.5 and the number of dips in the uniformity test shall be as given in Table 4. In this case, the pipe shall not show a fixed deposit of zinc even after the successive dipping operations of frequency given in Table 4.

7. Hydrostatic Test or Nondestructive Test

7.1 The black pipe shall be tested by 10.6 and the resulting hydrostatic characteristic or nondestructive characteristic shall conform either of the following two. The proference for which of them shall be left to thespecification by the purchaser or to the discretion of the manufacturer.

7.2 Hydrostatic characteristic (Applicable till the end of 1990) When a hydrostatic pressure of 25 kgf/Р {25 bar} (1) is applied, the black pipe shall withstand it witout leakage.
Note (1) 1 bar = 105Pa

8. Hydrostatic Characteristic

8.1 (Applicable on and after Jan. 1, 1991) When a hydrostatic proessure of 2.5 MPa is applied, the black pipe shall
8.2 Nondestructive Characteristic Anondestructive examination by either an ultrasonic test shall be made on the black pipe, and there shall be no signal greater than those produced by the artificial defects of the reference test block of division UE of the working sensitivity specified in JIS G 0582 or division EZ of the working sensitivity specified in JIS G 0583.

9. Dimensions, Weight and Dimensional Tolerances

9.1 The dimensions, weight and dimensional tolerancws of the pipes shall asfollows:
9.2 The length of each pipe shall, as a rule, be 5500 mm or over, the purchaser, however, may specify a length 3600 mm or over, as necessary.

10. Test

11. Inspection

12. Reinspection  the pipe may be determined for final acceptance by a retest specified in 4.4 JIS G0303.

13. Marking

Each pipe having passed the inspection shall be marked with the following items. However, the smaller pipes and other pipes specified by the purchaser may be bundled together and marked for each bundle by a suitable means. Im bptj cases. the order of arranging the marked items is not specified.

When approved by the purchaser, part of the items may be omitted.

(1) Letter symbol of grade

(2) Letter symbol denothing the manufacturing processes (5)

(3) Dimensions (6)

(4) Manufacturer's name or its identifying brand

Notes (5)
The letter symbol indicating the manufacturing processes shall be as follows, provided that the dash may be onitted leaving ablank.

Electric-resistance welded steel pipe otherthan hot-finished or cold-finished ones - E - G

Hot-finished electric-resistance welded steel pipe - E - H

Cold-finished electric-resistance welded steel pipe - E - C

Butt -welded steel pipe - B

(6)
The dimensions shall be expressed by the nominal size.

14. Report

The manufacturer shall submit the test report when previously required by the purchaser.
