A841 grade A class 1 plates API Std 650 austenitic stainless steel storage tanks

We have new significant API Std 650 austenitic stainless steel storage tanks projects in Nigeria. It is about crude oil storage tanks. With the development of our steel materials business in the Africa those years, Nigeria has been an important market to us. And we have many API Std 650 austenitic stainless steel storage tanks famous projects in local and also participated in a lot of governmental projects. This crude oil storage tanks project is a very big engineering, and lasts for years. This is the only initial stage. We are under negotiation about following installation and further demands etc. matters.

Allowable compressive stresses shall be in accordance with 5.5.4 except that for aluminum alloy plate the allowable compressive stresses shall be reduced by the ratio of the modulus of compressive elasticity to 29,000 for values of (t–c)/R less than 0.0175 and by the ratio of the minimum yield strength for the aluminum alloy in question to 30,000 for values of (t–c)/R equal to or greater than 0.0175 (see 5.5.2 for definitions). In all other equations in this standard API Std 650 austenitic stainless steel storage tanks where yield strength or modulus of elasticity is used, such as Equations 27 and 28, similar corrections shall be made for aluminum alloys.

The tank wall design of API 650 oil storage tank. Since there is no ventilation pipe directly connected with the outside on the top of the API Std 650 austenitic stainless steel storage tanks tank, the ventilation between the inside and outside of API 650 oil storage tank is realized by the respiration valve. The constant pressure of the respiration valve is 0.3kPa, so the pressure on the top of the tank is 0.3kPa.

On November 1st, our company organized some of company staff to visit Zhengzhou Children Welfare Institute, and gave children cookies and toys, as well as concerns to the Children. With the development of the society, disabled children gets increasing concerns and help from all walks of life. Fortunately, Chinese Government gives high concern to the handicapped children and has built Children Welfare Institutes all over the country to guarantee their lives.
