A678 grade A plates API standard 650 unanchored tanks
The API Std 650 standard published by the American Petroleum Institute (API) is designed to provide the petroleum industry with welded steel tanks for use in the API standard 650 unanchored tanks storage of petroleum products and other liquid products commonly handled and stored by the various branches of the petroleum industry.
Butt-welded joints used to fabricate large steel storage tank fittings shall be completely radiographed. Lines carrying liquid shall be hydrostatically or pneumatically pressurized at a minimum pressure of 35 lbf/in.2 and API standard 650 unanchored tanks butt welded joints shall be simultaneously visually examined (hydrostatic) or solution film tested (pneumatic) for tightness. If manufactured pipe has been hydrostatically tested previously to ASTM requirements, then only circumferential welds need to be examined.
X-ray inspection is mainly applicable to the internal inspection of pressure bearing parts and materials of metal oil tanks such as API standard 650 unanchored tanks. It can clearly find the blocky defects inside the welded joints. However, the cost and resource consumption of radiographic testing are large. Magnetic particle testing can effectively detect the surface and near surface defects of API standard 650 unanchored tanks etc. metal oil tanks, but magnetic particle testing can not effectively identify the internal defects of oil tanks.
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.

The company's headquarters has a well-established logistics distribution system, which can quickly transport the steel materials to the port through the contracted logistics companies. Professional contracted logistics companies can significantly reduce costs and various commodity-related expenses. Meanwhile, the flexible transfer ensures that the API standard 650 unanchored tanks steel materials can be shipped immediately after passing the quality inspection.
To provide customers with the most satisfactory service and realize the win-win of economic and social benefits, our company promises to provide excellent API standard 650 unanchored tanks products in this bidding, and in line with the attitude of being serious and responsible to customers, before sending goods to users, the API standard 650 unanchored tanks technical personnel shall confirm that there is no fault in the equipment before sending goods to users, and then send goods and products to users, and formulate the following service terms.
