Hello, I have a questing regarding weld repair allowed by API 5L in Annex C, Clause C.4.3 C.4.3 The total length of repaired zone on each pipe weld shall be < 5% of total weld length for SAW and COW weld seams. Submerged Arc Welded Helical (SAWH) pipe have inside and outside welds and...

Hello Everyone, We are SAWH pipe manufacturer, we carryout repair welding of API 5L Gr. X-70 pipes with Electrode E-9018. Please let me know, can we use electrode E-8018 instead of E-9018 on API 5L Gr. X-70 pipes. if yes, is re-qualification required. Product standard is silent about it...

Hi everyone, I would really grateful if anyone can help me in writing the Management of Change procedure according to API Q1 or share with me the the same Basically i am writing this first time and don't any any idea about MOC. Best Regards Zebmahar

Good day guys, Can anyone let me know, why the cold bending is preferred by the fabricators instead of hot bending? Even in the hot bending there is very little chance of cracking and tubes also get bend easily. Regards Zebmahar

Hello everyone I would like to know what is the difference between boiler tubes and super heater tubes, also let me know how much pressure and temperature these tubes can sustain. Kind Regards Zebmahar
