A516 grade 415 plates API Std 650 flat-bottom steel tanks
Above the water level, all API Std 650 flat-bottom steel tanks welded joints, all welds around openings, and all piping joints against which the pneumatic pressure is acting shall be checked with a solution film. A visual inspection may be substituted for the solution-film inspection if the welded joint has previously been checked with a vacuum box. The solution-film inspection shall still be made, above the water level, on all welds around openings, all piping joints, and the compression ring welds, including the attachment to the roof and shell.
Prevent the storage liquid from impacting the inner wall of the API 650 petroleum storage tank or increase the internal pressure, reduce the corrosion of the tank top and the tank wall, and extend the service life of the API Std 650 flat-bottom steel tanks storage tank.
In April 2018, our Philiphine customer purchased 1008 Tons API5L Gr.B ERW&Q345B SMLS pipe for offshore oil field resources drilling project. This is a regular demand almost two month, and we has been cooperated more than three times, totally around 2100 tons steel pipe since 2015 year.
}Define the welding sequence of API Std 650 flat-bottom 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.
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.
