A53 grade B pipe API Std 650 cylindrical welded storage tanks
API 650 internal floating roof tanks are generally called internal floating roof tanks, floating roof tanks, internal floating disk storage tanks, internal floating disk tanks, etc., specifically referring to API 650 storage tanks and oil tanks with aluminum, stainless steel, etc. The API Std 650 cylindrical welded storage tanks inner floating roof of series material is an environmentally friendly and economical storage tank that prevents liquid from volatilizing.
The API Std 650 cylindrical welded storage tanks stiffener ring and backing strip (if used) are primary components, and they shall comply with the requirements of API 620 storage steel tank Q.2.1. The stiffener rings may be fabricated from plate using an intermittent weld on alternating sides between the web and the flange.Except for aluminum or stainless steel tanks, all fillet welds shall consist of a minimum of two passes. The ends of the fillet welds shall be 2 in. from the rat hole (see Figure Q-1), and these welds shall be deposited by starting 2 in. from the rat hole and welding away from the rat hole. An acceptable alternative to the detail that includes stopping fillet welds 2 in. short of the rat hole would be to weld continuously through the rat hole from one side of the stiffener to the opposite side. All craters in fillet welds shall be repaired by back welding.
Personnel organization before the construction of the API Std 650 cylindrical welded storage tanks:The company shall select technical personnel, quality inspectors and material personnel with organizational ability and construction management experience to participate in the API Std 650 cylindrical welded storage tanks project construction. The construction personnel shall arrive at the construction site before the designated commencement date, investigate the construction site, build construction facilities, plan the construction steps, and analyze the potential safety hazards during operation.
