API Std 650 SUG II tanks manhole necks
API 650 tank has the advantages of less load on the floating plate, simple and light structure, and can save the central drainage pipe and rotating floating ladder on the API Std 650 SUG II tanks floating plate. The materials for easy construction and maintenance and sealing parts can avoid aging due to sunlight.
Crack treatment of API Std 650 SUG II tanks weld area: find out the crack tip with ray or ultrasonic flaw detection, drill cut-off holes at both ends of the crack with the cut-off method, the hole depth is slightly greater than the crack depth, or groove (crack stop groove) is made by angle grinder at both ends of the crack, shovel and grind the whole crack, and grind it into a suitable groove; use radiographic inspection and dye detection to verify that the crack has been completely excavated, and finally repair welding.
API 620 Tank Standard Post-heat Treatment (Stress Relief)The post-heat treatment now performed on pressure vessels is of established value, although the mechanism by which the improvement is realized may be open to debate. Post-heat treatment of API Std 650 SUG II tanks tank sections when the plate thickness exceeds 11/4 in. is required as stated in 5.25. In special cases, the possibilities of post-heat treatment after erection should be explored. Post-heating an insulated tank may be possible if an ample source of heat is readily available and if the rigidity of the tank is adequate.The thermal stress-relief treatment performed on pressure vessels is recognized as a means for reducing the probability of brittle failures.
