iron ductile pipe lines

[omarfawzy]

dear all
i have 30 km ductile pipe line and the work pressure will be not less than 20 bar what are the precautions steps to avoid the movement of the line and what is the pressure test value

Please elaborate on what you mean by movement in the line.

DIPRA has design manuals available on line:

There may be some ionformation that would help you from a practical stnadpoint with metric sized pipes e.g. at

(please also refer to any local governing standards).

Test at 1.5 times working pressure. You may have to go o a higher class of pipe to get the pressure. AWWA has standards for the allowable leakage. It is in gals. per inch diameter per mile of pipe per 24 hour period.
