CSA G40.21 Gr 38WT plates API 650 flat-bottom tanks

The hot weather in summer brings great security challenges to the vertical oil storage tanks, API 650 flat-bottom tanks standing outdoors. We must find some simple and effective methods to protect the API 650 flat-bottom tanks in order to make them safely spend the summer. As a API 650 flat-bottom tanks manufacturer, in order to reduce the direct sunlight rate of the vertical oil tank, reduce the temperature change of the oil tank, and reduce the evaporation loss of the oil tank, we usually adopt the measures of applying sunscreen paint and washing with warm water.The API 650 flat-bottom 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.API 650 storage tank is used for commonly used oil, gasoline, diesel, chemical and production water storage. API 650 flat-bottom tanks Storage tanks built to these standards are spread across U.S. refineries, terminals, pipelines, and production facilities. The API 650 detailed standard specifies the design, processing, welding, inspection and installation procedures for storage tanks.Based on the principle of “sincerity and win-win cooperation”, our company keeps forging ahead.
