API 650 carbon and low-alloy steel tanks qualification of welders

As we know, the vertical metal tank, API 650 carbon and low-alloy steel tanks is welded by many components, and the welding quality of each component determines the later use effect of the API 650 carbon and low-alloy steel tanks. Professional API 650 carbon and low-alloy steel tanks manufacturers should have a set of professional skills in the welding process of API 650 carbon and low-alloy steel tanks. Key points for weld inspection of vertical metal tank, API 650 carbon and low-alloy steel tanks:
1. It is strictly forbidden to paint the welds before passing the inspection.
2. Visual inspection shall be carried out for welds.
3. NDT shall be carried out on the weld.

After years of operation and accumulation, the company has formed an operation network covering major economic cities across the country, with a group of high-quality professional logistics technicians and management personnel, strong strength and stable logistics channels. The company's business operations include the loading and unloading of steel raw materials and finished materials, API 650 carbon and low-alloy steel tanks warehousing, and freight transportation. Our logistics service business has passenger transportation, automobile and construction machinery inspection, logistics information management and operations.

Under the same sealing effect, the internal API 650 carbon and low-alloy steel tanks floating roof API 650 tank can further reduce the evaporation loss compared with the external floating roof API 650 tank. This is due to the shielding of the fixed roof and the gas phase layer between the fixed roof and the inner floating plate, which has more significant heat insulation effect than the double disc floating roof of the API 650 carbon and low-alloy steel tanks external floating roof tank.

First of all, we should establish a correct concept of after-sales service. Service concept is an important part of corporate culture and a long-term enterprise value concept. Our company's after-sales service embodies the concept of "customer first, sincere service for customers". As long as we are in the "sincere service for users" under the guidance of the idea, I believe we will get rich returns.
