API 650 liquid-storage tanks roof plates

Design of a Double-wall Tank
The outer bottom, shell, and roof of a double-wall tank shall enclose an insulating space around the bottom, shell, and roof or insulation deck of the inner tank that contains the stored liquid. The annular space shall be maintained at a low positive pressure, which necessitates that the enclosure be vapor-tight. The Purchaser shall specify the design metal temperature and pressure of the inner tank and may specify the design temperature and pressure of the outer tank API 650 liquid-storage tanks. The Purchaser shall state the specific gravity of the content to be stored, roof live loads, wind load, earthquake load where applicable, and corrosion allowance, if any.

The welded steel API 650 storage tank API 650 liquid-storage tanks is designed, manufactured and installed on the surface according to the API standard system classification. API 650, API620 and API 12D belong to the API standards for professional construction.

With the fast development in Myanmar, Myanmar navy build frigate every year. We Cooperate with Myanmar Navy from 2015. They purchased 412 ton LR AH36 steel plate from us as trial order in 2015. After receiving the API 650 liquid-storage tanks goods, they speak highly of the quality and our service. After that they purchase the shipbuilding steel plate from us regularly. In May,2018, the Myanmar navy’s local representative visit our office and production line, and sign another contract 2025 ton steel order in our office.

Corrosion of the API 650 liquid-storage tanks body caused by external conditions such as high temperature, rain, humidity, or inadequate anti-corrosion measures of the oil storage tank itself, the water-bearing deposits in the oil storage tank caused corrosion and perforation of the inner surface of the oil storage tank bottom plate. Defects fatigue cracks caused by stress, with the accumulation of time, the compressive strength of the API 650 liquid-storage tanks body decreases and corrosion cracks occur.
