aluminum sheet 5086 API Std 650 austenitic stainless steel storage tanks

API 650 storage tanks API Std 650 austenitic stainless steel storage tanks are only suitable for containers that can evenly support the entire bottom and containers for non-refrigerated equipment with a design maximum temperature of 200 degrees Fahrenheit. It API Std 650 austenitic stainless steel storage tanks requires a minimum thickness of 3/16 inch. Other characteristics of the API 650 storage tank are: it is composed of carbon steel, austenitic duplex stainless steel and aluminum.

Before welding the API Std 650 austenitic stainless steel storage tanks, the professional skills of the welding personnel shall be fully assessed to ensure that the operators meet the corresponding welding qualifications. According to the technical standards, scientific and feasible process requirements are actually formulated. In the process of welding the edge plate of API Std 650 austenitic stainless steel storage tanks, electric welding is required on one side of the edge plate, so that the edge plate has a free shrinkage effect and greatly reduces the residual stress of the welding seam.

Investigation of Subgrade
On actual steel storage tank sites to be used, test borings or test pits, or both, may be made at the direction of a competent engineer who will specify the number and location. They need not be equally spaced but should be laid out to uncover possible weak spots.
In general, test loadings of subgrade at the bottom of test pits need be resorted to only when such heavy loading as may be imposed by footings for major column supports for spheres or similarly elevated API 620 low-pressure tanks is specified. Results may be deceptive if average load-bearing capacity over a considerable area is wanted. All field data shall be recorded with maps, and copies shall be supplied to all engineers concerned with design, erection, and later operation.

Every after-sales service shall have a detailed record of the customer's product problems and handling methods. The records shall be sorted into volumes and filed on a monthly basis, and submitted to the technical department for filing. The problems found in the after-sales service shall be summarized in a timely manner, discussed with the technical department, the quality inspection department and the production department, and a proper solution shall be proposed for the technical department to improve in a timely manner;

The main competitive means adopted by major domestic ports are to expand ports, build deep-water berths and channels, improve service quality to reduce the comprehensive cost of customers, and at the same time, to improve competitive advantage, we should also take appropriate measures to reduce relevant costs and prices.
