API650 bolted steel tanks for oil project lap-welded bottom joints

API650 bolted steel tanks for oil project lap-welded bottom joints

API650 bolted steel tanks for oil project lap-welded bottom joints

If additional requirements are met, higher internal pressures are allowed. API 650 only covers tanks that support the whole bottom evenly and API650 bolted steel tanks for oil project 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.

The API 620 large storage tank nozzle neck is fabricated by welding from 1/2-in. plate. The materials in the tank wall, the nozzle neck, and the reinforcing pad conform to ASTM A442 Grade 55. The main joints in the tank wall are fully radiographed, double-welded butt joints. The longitudinal joint in the nozzle neck is of the same type API650 bolted steel tanks for oil project but is not radiographed; however, the longitudinal joint and all other parts of the nozzle-and-wall-plate assembly have been shop stress relieved after fabrication, as required by 5.25. The adequacy of the reinforcement and attachment welds shown in Figure F-6 shall be determined.

API650 bolted steel tanks for oil project weld tightness test: remove dirt from the API650 bolted steel tanks for oil project weld, apply white powder emulsion, spray kerosene on the other side of the weld after drying. Because of the strong penetration of kerosene, if kerosene is sprayed after 12 hours (under low temperature conditions, the time can be extended), if the surface of the welded seam coated with white emulsion has no spots, the welded seam meets the requirements.

Keep in mind your mission and never forget your mission." At present, the BEBON steel leadership team unites the majority of cadres and employees to keep in mind their glorious missions, guided by Xi Jinping's ideology of socialism with Chinese characteristics in the new era, fully implementing the spirit of the 19th CPC National Congress, in-depth implementation of the requirements of the "three advances", pioneering spirit, and striving In order to lead high-quality development with innovation, build a new pattern of Anshan Iron and Steel's revitalization and development, strive to build the most internationally influential steel company, and make new contributions to the start of a new journey for BEBON Iron and Steel Group.

The mode of iron and API650 bolted steel tanks for oil project steel logistics transportation is mainly intercontinental ocean shipping and inland rail transportation. European ports have been very mature after years of development, such as Hamburg in Germany, Rotterdam in the Netherlands and Antwerp in Belgium. Relying on the huge market of the European Union, these ports are positioned in the logistics distribution function of cargo distribution and large import and export, and play a great role in the transportation of API650 bolted steel tanks for oil project steel logistics.

Our company will accept the product quality objection registration record, pass it to the API650 bolted steel tanks for oil project production unit and relevant departments, and timely coordinate the supervision of product API650 bolted steel tanks for oil project quality objection. Our company coordinates the relevant department personnel to the customer unit to carry on the investigation, the processing.
