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 standard 650 self-anchored 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.API 650 petroleum storage tank pipeline stress and product pressure, tank pressure, uniform or non-uniform temperature difference between the tank wall and the tank bottom, which cause the radial displacement and longitudinal rotation of the API standard 650 self-anchored tanks tank wall at the opening to affect the oil tank wall The impact is obvious. Therefore, the design must ensure that the load applied by the external pipeline on the opening of the tank wall is within the safety limit. If the stress of the API standard 650 self-anchored tanks connecting piping is not handled properly, the wall of the API 650 petroleum storage tank may deform or even rupture, causing a major accident.With the fast development in Myanmar, Myanmar navy build frigate every year. Bebon Cooperate with Myanmar Navy from from 2015. They purchased 412 ton API standard 650 self-anchored tanks LR AH36 steel plate from Bebon as trial order in 2015. After receiving the goods, they speak highly of the quality and bebon's service. After that they purchase the shipbuilding steel plate from bebon regularly. In May,2018, the Myanmar navy's local representative visit our office and production line, and sign another contract 2025 tons API standard 650 self-anchored tanks LR A shipbuilding steel plates order in our office.Strictly control the welding groove forming of API standard 650 self-anchored tanks: in order to ensure the geometric dimension of assembly and good welding of welding seam, before hoisting and laying, the edge of all metal vertical storage tank plate shall be polished by grinder, and the flatness of plate shall be ensured according to the design requirements. Strictly control the size of API standard 650 self-anchored tanks weld assembly: measures must be taken to strictly control the assembly size of metal vertical tank bottom plate during assembly.Both parties shall confirm the API standard 650 self-anchored tanks material object and the quality of the products, confirm the reasons for the defects and the quality of the products, and sign the quality inspection agreement. Major quality objections shall be reported to relevant leaders in a timely manner, and shall be discussed and solved with the API standard 650 self-anchored tanks steel plant.
