Impact Tests for High Alloys
Impact tests are not required for oil steel storage material nickel alloy welds made with electrodes/filler metals covered by AWS Specification A5.11 or AWS Specification A5.14, provided the nominal nickel content is 50% or greater, and the weld is deposited by the shielded metal-arc welding (SMAW), gas metal-arc welding (GMAW), gas tungsten-arc welding (GTAW), or plasma-arc welding (PAW) processes. When A5.11/A5.14 specifies the nickel content as a “remainder,” the nickel content shall be determined by summing the maximum specified values of the other elements (use the average specified value for elements with specified ranges) and subtracting from 100%.

The company has been engaged in the design, construction and installation of foreign API 650 standard API standard 650 flat-bottom oil storage tanks storage tanks for a long time. It has the international qualification of ASME welding technology, has the design ability of API 650 oil tanks and API 650 storage tanks, and has pressure vessel design and manufacturing license and GC pressure pipeline installation license. Certificate, API standard 650 flat-bottom oil storage tanks petrochemical equipment pipeline general contracting qualification, safety production license, international trade import and export license.

In December, 2018, our Vietnam customer purchased 352 tons SA387Gr12Cl2 and SA387Gr11Cl2 API standard 650 flat-bottom oil storage tanks steel plates for their tank fabrication project. The customer need those cargo urgently, and we keep many stock in warehouse , it only takes about 3days we collect total cargo for shipping to customer. The customer are very appreciate our quality and service. They API standard 650 flat-bottom oil storage tanks become our regular customer and repeat order to us every month.

Large-scale vertical API standard 650 flat-bottom oil storage tanks mostly use internal tank bottom heating coils to heat the medium stored in the storage tanks. The heating coils are mostly smooth tube structures arranged in an annular circle along the bottom of the API standard 650 flat-bottom oil storage tanks. Commonly used heating methods include hot oil circulation heating method and hot water steam circulation heating method. The hot oil circulation heating method is to continuously extract part of the liquid medium from the storage tank, and then return it to the container to mix with the medium in the tank after heating, and the heat is quickly transferred through mechanical stirring.

The company conducts periodic and targeted training and guidance for after-sales service personnel. As the saying goes, "no one is perfect, no gold is red", to help after-sales service personnel improve service skills and correct service attitude. Carry out relevant technical training for after-sales service personnel, so that after-sales service practitioners have professional product knowledge.
