A516 grade 70 plates API 650 petroleum storage tanks

Welding of API 620 Steel storage tank Primary Components
The following primary components shall be joined with double butt-welds that have complete penetration and complete fusion except as noted:
Longitudinal and circumferential shell joints and joints that connect the annular bottom plates together. When approved by API 650 petroleum storage tanks Purchaser, these may be welded from a single side provided temporary non-fusible backing is used with complete penetration and complete fusion. Both sides of the joint shall be 100% visually examined as specified in 7.15.5.

This specification, in conjunction with API 650 Standard, prescribes minimum standards for the API 650 petroleum storage tanks design, supply fabrication, erection, and testing of field erected welded steel storage tanks complete with accessories as specified herein and as shown on attached datasheets and/or drawings.

In 30th,Dec,2018--2th,Jan,2019, One Malaysian customer come to visit our factory to inspect their goods about CCS-AH36 steel plate. This customer is a famous shipyard in Malaysia. Their company has the business scope of tourism, API 650 petroleum storage tanks shipbuilding, transportation and so on. As a terminal manufacturer, they have strict requirements on quality . After visiting our factory, the customer are very satisfied with the quality of this batch of products.

The lip seal of floating roof storage tank, API 650 petroleum storage tanks relies on the sliding contact between elastic lip and tank wall. This kind of seal has strong applicability, but the requirements of manufacturing technology and material selection are high, and the determination of elastic seal also exists. The secondary seal of floating roof storage tank, API 650 petroleum storage tanks is to add a seal on the basis of primary seal. It is proved by experiments that the secondary seal can reduce the liquid consumption by more than 50%, and has a more significant effect in safety.

Compared with other fast-moving consumer goods, steel consumption is obviously different, with a wide range of use and a long service life. Therefore, the quality and service of steel materials are particularly important. Service is always one of our top concerns, especially after-sales service. We have mature after-sales service team, and can help you solve problems professionally during application of the steel materials.
