CSA G40.21 grade 260W plates API standard 650 carbon and low-alloy steel tanks

The establishment of a correct method for evaluating the life of API standard 650 carbon and low-alloy steel tanks requires the preparation of criteria related to the strength and cracks of API standard 650 carbon and low-alloy steel tanks, mechanical damage mechanisms, corrosion mechanisms, and mathematical models of fatigue crack growth, etc., which are compiled into computer programs. In the process of programming the program, it is required to select the operating parameters, plates, reinforcement accessories, metal properties, corrosion levels, mechanical damage defects and other data of the oil storage tank under various conditions.

Hydrostatic Test
The API standard 650 carbon and low-alloy steel tanks product shall be vented to the atmosphere when it is filled with or emptied of water. During water filling, the elevations of at least four equidistant points at the bottom of the tank shell and on top of the ringwall or slab shall be checked. Differential settlement, or uniform settlement of substantial magnitude, requires an immediate stop to water filling. Any further filling with water will depend on an evaluation of the measured settlement.

Tanks which are designed following rules and guidelines of API 650 are API 650 tanks. API 650 API standard 650 carbon and low-alloy steel tanks is the governing code for Welded tanks for Oil storage normally operating in the atmospheric pressure range. The code API 650 provides guidelines for design, fabrication, material, erection, and inspection of welded vertical and cylindrical storage tanks. Such API standard 650 carbon and low-alloy steel tanks Tanks must be above ground with a closed or open top.

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.

Since its establishment, the company has participated in several key railway and highway projects. After years of development, the company’s API standard 650 carbon and low-alloy steel tanks domestic market has been exported to more than a dozen provinces and cities including Kunming, Shenzhen, Hunan, Sichuan, Shanghai, Nanjing, Heihe, Jilin, Inner Mongolia, and Xinjiang . International trade is exported to Kazakhstan, South Korea, Vietnam, South Africa and many other countries, and has been well received by customers.
