API Std 650 mechanically-anchored flat-bottom tanks qualification of welding procedures

The safety inspection of atmospheric storage tank, API Std 650 mechanically-anchored flat-bottom tanks is divided into external inspection, internal and external inspection and comprehensive inspection. External inspection shall be conducted at least once a year, internal and external inspection shall be conducted at least once every three years, and comprehensive inspection shall be conducted at least once every six years. The safety inspection of large atmospheric storage tanks, API Std 650 mechanically-anchored flat-bottom tanks requires special attention: the parts where the liquid level often fluctuates, the parts that are susceptible to corrosion, and the parts that are deformed and worn during use should be checked.

In addition to our own truck fleet, we also have long-term cooperation with certain logistics companies to ensure that we can deliver API Std 650 mechanically-anchored flat-bottom tanks goods in time and smoothly. At the same time, because of the long-term cooperation and huge shipping volume, we can get a good transportation price and save transportation cost for the company and customers. Meanwhile, we have Shipping Department to arrange shipping work in advance. So as not to waste time on transportation both in land and on the sea.

In API 650 oil storage tank, when the mixing ratio of combustible medium and air reaches a certain limit, it is easy to cause explosion. Therefore, it is necessary to add API Std 650 mechanically-anchored flat-bottom tanks external floating roof to open cylindrical steel API Std 650 mechanically-anchored flat-bottom tanks tank. At present, the external floating roof is most suitable for large-scale API 650 oil storage tank in China, ranging from 20000, 30000, 50000 cubic meters to 100000 cubic meters.
