API standard 650 aboveground steel oil storage tanks single-welded lap joint

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 effect of air pressure on the API standard 650 aboveground steel oil storage tanks tank walls of the API 650 tank must be considered when the design pressure is greater than 2 kPa.The fixed point method can be used to design the tank wall of atmospheric or micro internal pressure API standard 650 aboveground steel oil storage tanks storage tank.

In 30th,Dec,2018--2th,Jan,2019, One Malaysian customer come to visit our factory to inspect their goods about CCS-AH36 steel plate. This customer is a famous shipyard in Malaysia. Their company has the business scope of tourism, API standard 650 aboveground steel oil storage tanks shipbuilding, transportation and so on. As a terminal manufacturer, they have strict requirements on quality . After visiting our factory, the customer are very satisfied with the quality of this batch of products.

API standard 650 aboveground steel oil storage tanks Breathing valve: The function of the oil tank breathing valve is to adjust the oil and gas pressure in the tank. When the pressure in the tank is too high, part of the excess oil and gas will be discharged through the breathing valve to reduce the pressure in the tank; when the pressure in the tank is too low, through breathing The valve sucks in air from the outside of the tank to increase the pressure in the tank and keep it constant with the atmospheric pressure. The breathing valve is usually installed at the top of the oil tank.

The after-sale service of iron and steel products includes after-sale tracking service, technical guidance, transfer of relevant bills, handling of objections and many other contents. The handling of quality objections accounts for a large proportion. When dealing with these problems, we should distinguish the responsibilities, and compensate or return the inconvenience or loss caused to users due to steel.
