API Std 650 petroleum storage tanks gauging platform

One of the most widely used design codes is the API 650 Standard, from the American Petroleum Institute. The main objective of this standards API Std 650 petroleum storage tanks is, through the requirements contained in its various sections, to facilitate the purchase and construction of vertical, aboveground, welded fabricated tanks assuring that required safety regulations are met.

API 620 Steel Oil Tank Bottom and Shell Support
The tank API Std 650 petroleum storage tanks under-bottom insulation shall be designed to resist the combined pressures from the product load, the overturning seismic load and the vertical seismic load. These seismic pressures may be combined by SRSS.
The bearing ring under the shell shall be designed to resist the calculated OLE peak compressive force in the tank shell due to overturning (see API 650 oil tank, Section E.6.2.2), including dead and live loads. A 33 % increase in allowable bearing stress is permitted.

API Std 650 petroleum storage tanks, Oil tanks can be divided into above ground storage tanks, underground storage tanks, offshore tanks and submarine tanks according to their installation positions. Oil tanks can be divided into crude oil tanks, fuel oil tanks, lubricating oil tanks, edible oil tanks, etc.. According to the use of oil tanks, oil tanks can be divided into production tanks, storage tanks, etc.. According to the external style, oil tanks can be divided into vertical tanks, horizontal tanks, etc.. According to the composition structure, oil tanks can be divided into fixed roof storage tank, floating roof tank, spherical tank, etc.

we develop very well through those years even the external environment is not conducive to the whole steel industry. With the prosperity of our group, our company always bear its staff who contributes to its growth in mind, and always on the way to improve welfare and treatment. That makes us staff and work with pleasure. On the other way, they creat a better and stronger our group. That may be one of the key factors why we develop so rapidly those years. Here we can say proudly “we are family”.

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.

The after-sales service personnel understand the user's ideas and needs in detail, and stand on the other side's position and interests. Actively communicate with users and help them solve practical problems. This not only solves the service problem, but also improves the customer's trust in the company.
