A841 Gr A Cl 1 plates API 650 self-anchored tank

When the API 650 self-anchored tank is welded, the weldment should be fixed rigidly. After welding, when the weldment is cooled to normal temperature, the rigid fixation can be removed, which can effectively prevent angular deformation and wave deformation. Although some measures have been taken, the welding deformation of API 650 self-anchored tank is still unavoidable, so it is necessary to take corrective measures to compensate the deformation. Mechanical correction is to make the parts easy to deform in the welding process by mechanical or other rigid materials to produce simple deformation, so as to restore the state before welding.

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

Through the operation and management, brand advantage and improve pre-sales, sale of after-sales service, the efforts of the company into the industry leading enterprises.Relying on perfect quality management system, it has built up competition predominance and provided high quality, favorable price and perfect after service for customers.

This specification, in conjunction with API 650 Standard, prescribes minimum standards for the API 650 self-anchored tank design, supply fabrication, erection, and testing of field erected welded steel storage tanks complete with accessories as specified herein and as shown on attached datasheets and/or drawings.
