A334 grade 1 pipe API standard 650 low-alloy steel tanks

The floating roof is the top cover floating on the liquid level, so the sealing performance of API standard 650 low-alloy steel tanks API 650 oil storage tank is very important. The floating plate mainly adopts elastic packing, and at the same time, it is compressed with the wall of API 650 oil storage tank with pressure strip around, and fixed with the floating plate with bolts. After the API standard 650 low-alloy steel tanks floating plate is lowered to a certain position of about 1.8m, a prop will support the floating plate to keep it in position.

After the API standard 650 low-alloy steel tanks is manufactured, air tightness test and water filling test are carried out according to the design requirements, and the pipeline must be subjected to pressure test to fully meet the acceptance technical specifications. Improve the quality assurance system, adhere to the principle of who constructed is responsible for the quality of the project, conduct regular quality inspections, and immediately rectify any problems. Fill in the API standard 650 low-alloy steel tanks installation technical records in time to ensure the synchronization, integrity and reliability of the technical data.

Inspection of Butt-welds in Piping
Butt-welds in piping and in API standard 650 low-alloy steel tanks pipe fittings within the limitations of 1.3.2 (including the annular space of double- wall tanks) shall be inspected in conformance with API 620 oil tank standard Q.7.7.2 through Q.7.7.6. Longitudinal welded joints in piping that contains liquid shall be completely radiographed except for manufactured pipe welded without filler metal, 12 in. or less in diameter, which is tested hydrostatically or by eddy current to ASTM requirements.

Management information and high efficiency. Because of the rapid flow of API standard 650 low-alloy steel tanks goods, container multimodal transport and "door-to-door" transport, it is required that the port must have a modern information network, so that it can have the comprehensive capabilities of all-weather access, rapid loading and unloading, customs clearance, collection, distribution, storage and transportation
