A333 grade 6 pipe API 650 mechanically-anchored steel tanks

The interior of API 650 storage tanks to be internally lined or coated must have all edges rounded to a minimum of 3 mm radius. Internal welds must be completely seal welded, ground smooth, and free from API 650 mechanically-anchored steel tanks surface porosity, pockets, and high spots. Remove weld spatter. Vendor as specified on API 650 storage tanks drawing must perform additional surface preparation.

Define the welding sequence of API 650 mechanically-anchored steel tanks bottom plate: the welding sequence of metal vertical storage tank shall be carried out according to the procedure required by the welding scheme. Spot welding shall be consistent with the formal welding requirements, and no spot welding shall be carried out for the weld not welded. Back bar should be added to prevent deformation when welding the full length seam of middle plate, butt joint of edge plate and turtle shell joint.

Suggested Practice Regarding Installation of Low-pressure Storage Tanks
Access: All openings and accessories for tanks API 650 mechanically-anchored steel tanks constructed according to this standard shall be installed so that any periodic inspections required can be readily made.
Corrosion: When a tank bottom rests directly on the ground, a survey shall be made to establish the need for cathodic protection.
Drainage: All tanks in which water might accumulate under the hydrocarbon contents shall be provided with adequate drains that are suitably protected from freezing.

Our quality control department will do inspection for details of the steel materials API 650 mechanically-anchored steel 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.

The company's logistics adopts the method of cooperation with logistics companies. As a third-party logistics company is engaged in the operation of multiple logistics projects, it can integrate various logistics resources, making the logistics operation cost relatively low and the logistics operations more efficient. Thus we can provide more professional logistics services, while also focusing on our core business of steel materials.
