A678 grade A plates API Std 650 special tank

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 Std 650 special tank Purchaser, these may be welded from a single side provided temporary non-fusible backing is used with complete penetration and complete fusion.

The Egypt customer ordered 130 tons API Std 650 special tank stainless steel plate in stock, and this batch has left port today for its destination today(October 25th, 2019). 316l stainless steel is molybdenum-bearing austenitic stainless steel. This material has better corrosion resistant property than 304/314L for it's higher Ni and Mo content. (it is considered to be marine grade stainless steel, not suitable for warm sea water treatment). 316L austenitic stainless steel supplied by our company has good formability and weldablity, additionally it is proved to have excellent properties of tensile, creep and stress-rupture strengths in elevated temperature environment.
