ASTM A662 plates API 650 ambient temperature tanks

Welding inspection of bottom plate of API 650 ambient temperature tanks, vertical oil tank: During the fabrication and installation of API 650 ambient temperature tanks, the bottom edge plate is welded first. According to the requirements of the technical standard, penetrant inspection is required for the weld of edge plate at the bottom of API 650 ambient temperature tanks, that is, penetrant testing is required for each weld bead priming, filling and capping. In the process of testing, if any defect is found, it shall be repaired immediately. After the repair, the surface coloring penetrant test shall be conducted again until the test result is qualified.The design metal temperature of API 650 ambient temperature tanks each component exposed to the liquid or vapor being stored shall be the lower of the following:
a)The minimum temperature to which the tank contents will be refrigerated, including the effect of subcooling at reduced pressure.
b)The minimum metal temperature anticipated when the atmospheric temperature is below the refrigerated temperature (see 4.2.1). The effectiveness of the insulation in keeping the metal temperature above the expected minimum atmospheric temperature shall be considered.One of the most widely used design codes is the API 650 Standard, from the American Petroleum Institute. The main objective of this standards API 650 ambient temperature tanks is, through the requirements contained in its various sections, to facilitate the purchase and construction of vertical, aboveground, welded fabricated tanks assuring that required safety regulations are met.Our company has a strong, professional R & D team and advanced and perfect sales service concept, which makes our API 650 ambient temperature tanks products have a high visibility and market share at home and abroad.
