Design and construction of foundations for API 650 stainless steel storage tanks

This API 650 tank standard is designed to provide industry with tanks of adequate safety and reasonable economy for use in the API 650 stainless steel storage tanks storage of petroleum, petroleum products. and other liquid products.

Inspection of Butt-welds in Piping
Butt-welds in piping and in API 650 stainless steel storage tanks pipe fittings within the limitations of 1.3.2 (including the annular space of double- wall tanks) shall be inspected in conformance with API 620 oil tank standard Q.7.7.2 through Q.7.7.6. Longitudinal welded joints in piping that contains liquid shall be completely radiographed except for manufactured pipe welded without filler metal, 12 in. or less in diameter, which is tested hydrostatically or by eddy current to ASTM requirements.

The lip seal of floating roof storage tank, API 650 stainless steel 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 stainless steel 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.
