Dear experts,
3" size SS piping (sa 312 tp 304) is found as leaking in few places (near to weld joint, base pipe area etc..).the service is potable water.sub- contractor saying it might be due to high chloride content (830ppm) or defective material (leaks mostly found in 1 heat no.).which could be more relevant? If for material, what are the tests for confirmations? Kindly share your views.
Thanks in advance,
Kumar.
