API standard 650 mixed material tanks single-welded lap joint

Our quality control department will do inspection for details of the steel materials API standard 650 mixed material tanks before delivery We would invite the customer side to attend the inspection together If they can not come, we will also take rich pictures for them to check Meanwhile, we will publish inspection report and send them the PDF version Besides, we accept any third party inspection such as SGS, BV, etc And our quality control department will support the third party to inspect the steel materials smoothly and try our best to deliver the qualified steel materials to customers earlier,API standard 650 mixed material tanks. Visual InspectionUpon completion of all the foregoing tests, the pressure in the tank shall be released and a thorough visual inspection shall be made of both the inside and outside of the tank, giving particular attention to all internal ties, braces, trusses, and their attachments to the walls of the tank. Anchors shall be checked for snug tightness and adjusted if required. Anchor threads shall be fouled by peening or tack welding to prevent loosening. In lieu of thread fouling, double nuts may be used.Rate of Water Filling and Water TemperatureThe rate at which water is introduced into a tank for a hydrostatic test shall not exceed 3 ft of depth per hour. The foundation, venting equipment, or other conditions may limit the water filling to a lower rate. Pressure shall not be applied above the surface of the water before the tank and its contents are at about the same temperature.If additional requirements are met, higher internal pressures are allowed. API 650 only covers tanks that support the whole bottom evenly and API standard 650 mixed material tanks tanks in non-refrigerated service that have a maximum design temperature of 200 degrees F. It requires that you have a minimum material thickness of 3/16 inch.Integrity based:To customers, we should value our credit and keep our good image forever.To colleagues: respect each other, trust each other, make efforts togetherService first:Customer satisfaction is always the first pursuit.The company provides customers with not only advanced technology and high-quality API standard 650 mixed material tanks products, but also the spirit of credit and service.Innovation:We are good at learning, drawing on the strengths of all, innovating and developing, introducing, researching and developing the latest technology, and making our products have a stronger vitality.Generally speaking, the duration of the "exhalation" of the API standard 650 mixed material tanks is longer than that of the "inhalation" of the API standard 650 mixed material tanks every day. There are many factors affecting the "small breathing" loss, mainly including the following points: the change of temperature difference between day and night, sunshine time of the API standard 650 mixed material tanks location, open area of the API standard 650 mixed material tanks, atmospheric pressure, filling degree of API standard 650 mixed material tanks, etc. When the API standard 650 mixed material tanks is full of gas, the space volume is small, and the "small breathing" loss is less; if the space volume is large, the loss is also large.
