API 5L grade B pipe API 650 welded storage tanks

,API 650 welded storage tanks. belongs to metal oil tank. Metal oil tank is a kind of vessel made by welding steel plate. The common shapes of metal tank are vertical metal tank, horizontal metal tank and spherical metal tank. The advantages of API 650 welded storage tanks etc. metal oil tank are good sealing, not easy to leak, can be installed with heating and insulation function, metal tank can withstand high internal pressure, large vertical metal tank such as API 650 welded storage tanks also has the characteristics of small floor space and large storage capacity.The hardness of the welds contacting these environments, including the heat-affected zones, shall be considered. The weld metal and adjacent heat-affected zone often contain a zone of hardness that is well in excess of a value of 22 on the Rockwell C scale and could be expected to be more susceptible to cracking than would unwelded metal. Any hardness criteria shall be a matter of agreement between the Purchaser and the API 650 welded storage tanks manufacturer and shall be based on an evaluation of the expected hydrogen sulfide concentration in the product, the possibility of moisture being present on the inside metal surface, and the strength and hardness characteristics of base metal and weld metal.API 650 "welded storage tanks" API 650 welded storage tanks is a standard developed and issued by the American Petroleum Institute (API), which specifies the minimum requirements for the design, manufacture, installation and inspection of welded storage tanks.Service concept: first time to understand customer needs, first time to solve customer worriesVision: to be the leading steel materials supplier in the worldWorking principles: Keep promises; Spare no efforts; Be practical and innovative; Pursue excellenceTalent concept: build a team with a dream and complete a dream with a team!Family culture: we rely on the principles of equality, trust, appreciation and family love to form a harmonious and warm family!We have a professional production team and high-quality production equipment, and we also have a great API 650 welded storage tanks advantage in price, with its own factory, large-scale production to reduce the price.
