API standard 650 storage tank convective spectral acceleration parameter

The mechanical seal of floating roof API standard 650 storage tank relies on mechanical force to press the sealing steel plate tightly against the tank wall, so that it can slide on the tank wall and avoid gap as far as possible. However, mechanical seal has high requirements for the geometry of storage tank and poor adaptability, so mechanical seal is rarely used in newly built floating roof API standard 650 storage tank.Qualifications of API 620 Storage Tanks ExaminersExaminers for tanks constructed according to the rules in this standard shall have had not less than 5 years experience in design, construction, maintenance and/or repair, or in the responsible supervision of the construction, maintenance and/or repair of various types of unfired pressure vessels and/or API standard 650 storage tank tanks, including at least 1 year of experience in the construction or supervision of the construction of vessels or tanks by fusion welding. Satisfactory completion of a suitable course of training approved by the Purchaser or the Purchaser’s agent may be substituted for 3 of the 5 years experience. However, training cannot replace more than 6 months of the required experience on fusion-welding construction.Similarities between API 650 and API 620 tanks Both tanks are used for storage purposes. Both API 620 and API 650 containers API standard 650 storage tank can be made of carbon steel, austenitic stainless steel and nickel alloy (only for low temperature)."Hard and solid, honest commitment, practical effect".
