7.5m diameter API Std 650 cylindrical liquid-storage tank

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 API Std 650 cylindrical liquid-storage tank 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.

API 650 is constructed from carbon steel, austenitic duplex stainless steel, and API Std 650 cylindrical liquid-storage tank aluminium A Welding Certification is stipulated by American Society of Mechanical Engineers (ASME), Section 10. There is a required inspection, no third party. The inspection cost is the cost of the NDE.

In April 8th, 2018, our Philiphine customer purchased 1008 Tons API 5L Gr.B ERW pipes &Q345B seamless steel pipe for offshore oildfield resources drilling project. This is a regular demand almost every two month, and we has been cooperated more than three times, totally around 2100 tons API 5L Gr.B steel pipeline since 2015 year. We can supply the relative certificated for the API 5L Gr.B ERW pipes products like SGS report, B/L &Form M, and mill test certificate.

According to the standard of head of API Std 650 cylindrical liquid-storage tank, there should be no crack, delamination, inclusion and other defects on the groove surface, which is consistent with the steel plate standard. The API Std 650 cylindrical liquid-storage tank head polishing can adopt different technology according to different requirements, including rough polishing, medium polishing and fine polishing. Only the materials used for the third type of pressure vessels must be retested, and the materials used for the first and second class pressure vessels are not generally re inspected.

With a high-quality and complete after-sales service system, the company solves the user's hindrance and improves the reliability of steel API Std 650 cylindrical liquid-storage tank product quality. Reaching every corner of the globe with professional services, users anywhere can get thoughtful and detailed services form us is our pursue.
