We deal in five types of C.I. PIPES. Below are some small details on them.
|
|
|
TOLERANCE ON LENGTH :
| Socket and Spigot Pipes |
= |
± |
100 mm |
| Plain ended Pipes |
= |
± |
100 mm |
| Flanged Pipes |
= |
± |
10 mm |
TOLERANCE ON MASS :
| Socket and Spigot Pipes |
= |
± |

HYDROSTATIC TEST :
For Hydrostatic Test, the Pipes are kept under pressure for 15 seconds. They are struck moderately with a 700 gm hammer, withstanding the pressure test without showing leakage, sweating or other defect of any kind. |

The standard working length of Pipes is 2.75 mtr. long (9 feet approx.) uto 600 mm dia and 2 mtr. long above 600 mm dia.
HYDROSTATIC TEST :
Pipes are tested hydraulically to prevent leakage, sweating or other defects of any kind. The pressure is applied internally, and steadily maintained for a period of 15 seconds, when pipes are struck moderately with a 700 gm. hammer. |
