1100 aluminum rod API 650 stainless steel storage tanks
API 650 stainless steel storage tanks Manhole: The manhole is used for the operator to enter and exit the oil tank for inspection, cleaning and repair. For the convenience of personnel access, the installation position of the manhole is generally on the center line of the oil tank bottom, and the vertical oil tank is installed at the lowest layer of the tank wall. API 650 stainless steel storage tanks Light-transmitting hole: Light-transmitting hole is also called day-lighting hole. It is used for lighting and ventilation when inspecting, repairing and scrubbing the oil tank. It is generally installed on the top of the oil tank above the inlet and outlet pipes.
The hardness of the welds contacting these environments, including the heat-affected zones, shall be considered. The weld metal and adjacent heat-affected zone often contain a zone of hardness that is well in excess of a value of 22 on the Rockwell C scale and could be expected to be more susceptible to cracking than would unwelded metal. Any hardness criteria shall be a matter of agreement between the Purchaser and the API 650 stainless steel storage tanks manufacturer and shall be based on an evaluation of the expected hydrogen sulfide concentration in the product, the possibility of moisture being present on the inside metal surface, and the strength and hardness characteristics of base metal and weld metal.
Test welds of each API 650 tank nozzle and manway reinforcing pad (or each section of multiple piece pad) using dry air and apply a soap solution test in the presence of Purchaser's Inspector before hydro testing the API 650 stainless steel storage tanks tank. Tap one inch NPT test hole in each pad or section.
