API Std 650 horizontal tank shell nozzles

API 650 petroleum storage tanks use lightning protection, anti-static, and fire protection measures. The internal corrosion protection should be determined according to the API Std 650 horizontal tank storage medium, and the outer wall corrosion protection should be determined according to the soil quality of the buried tank.

The head of API Std 650 horizontal tank etc. vertical oil tank is the end cover on the top of vertical oil tank. It is used to separate the oil stored in the tank and the medium outside the tank, and also used to bear the pressure on the top of the vertical oil tank. The quality of the head is closely related to the long-term safety of the API Std 650 horizontal tank. The head surface can be divided into convex shape, cone shape and flat shape according to its shape. The oil tank head can not be disassembled after welding.

Inspection of Butt-welds in Piping
Butt-welds in piping and in API Std 650 horizontal tank 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.
