Seeking advice on the issue of spherical tank leg supports
Thread Content
Is that so? Are there any standards for the column legs of spherical tanks used in pressure vessels? Let me explain the whole situation. Normally, the column legs in our family’s structures are made by welding rolled steel plates; we purchase the steel plates ourselves and fabricate them according to the design specifications. However, this year, the inspection agency informed us, in accordance with GB12337, that the column legs of spherical tanks must be made of steel pipes produced by reputable manufacturers, and we cannot use the welded rolled steel plates method. Do any of you experienced professionals have any good standards that I could learn from? Thank you in advance!
It’s possible to use sheet metal roll welding; testing is required. If it’s DN800, the pipes won’t be available for purchase
