API 650 low-alloy steel tanks shell manholes and nozzles
The engineering quality of API 650 low-alloy steel tanks not only affects production and operation, but also affects the life safety of the staff. The factors affecting the API 650 low-alloy steel tanks construction quality are all aspects, any link, any part of the problem will affect the whole project, so the quality management is paid more and more attention. How to ensure the engineering construction quality of oil tank? First, make API 650 low-alloy steel tanks construction technical preparation carefully, understand the design intent, master the construction acceptance specification, and make detailed construction technical disclosure to the construction team.
Design of Reinforcement for Single Openings in Tank WallsThe 20 in. x 29 in. obround manhole shown in Figure F-5 is located in solid plate in the sidewall of a cylindrical storage tank 45 ft in diameter in an area where the thickness of the wall plate, tw, is 1/2 in. No corrosion allowance is required. The total internal pressure, Pl + Pg, at the horizontal centerline of the opening is 27.5 lbf/in.2 gauge. The thickness of the wall plate, t, required by 5.10.3 for the latitudinal unit forces, T2, acting at this level is 0.485 in. The manhole neck is fabricated by welding from 3/8 in. plate. The materials in the API 620 tank wall, the manhole neck, and the reinforcing pad conform to ASTM A516 Grade 60. The joints in the welded steel storage oil tank wall and the longitudinal joint or joints in the manhole neck are double-welded butt joints, spot radiographed in accordance with 7.16 and 7.17.
The API 650 petroleum storage tank standard is one of the most widely used design specifications. It is the API 650 standard of the American Petroleum Institute. The main goal of the API 650 standard is to promote the purchase and construction of vertical, above-ground, and welded manufacturing API 650 low-alloy steel tanks tanks through the requirements contained in its parts to ensure that the required safety regulations are met.
Group consciousness is an important psychological factor for the formation of enterprise internal cohesion. The formation of API 650 low-alloy steel tanks enterprise group consciousness makes every employee of the enterprise regard their work and behavior as an integral part of the realization of enterprise goals, make them feel proud of themselves as a member of the enterprise, have a sense of honor for the achievements of the enterprise, and thus regard the API 650 low-alloy steel tanks enterprise as the community and belonging of their own interests.
