API Spec 5L pipe API Std 650 insulated tanks

API was established in 1919. It is the first national-level business association in the United States. It is one of the earliest and most successful chambers of commerce in the world to formulate standards. An important task of API API Std 650 insulated tanks is to be responsible for API 650 oil storage tanks and natural gas. Standardization of industrial equipment to ensure the safety, reliability and interchangeability of equipment used in the industry.

All API Std 650 insulated tanks fillet welds shall consist of a minimum of two passes. The ends of the fillet welds shall be 2 in. from the rat hole, and these welds shall be deposited by starting 2 in. from the rat hole and welding away from the rat hole. An acceptable alternative to stopping fillet welds 2 in. short of the rat hole would be to weld continuously through the rat hole from one side of the stiffener to the opposite side. All craters in fillet welds shall be repaired by back welding.

When the day light gradually decreases, the temperature of oil in the API Std 650 insulated tanks will also decrease, the evaporation speed will gradually slow down, and the pressure in the API Std 650 insulated tanks will also decrease. When the pressure in the API Std 650 insulated tanks is lower than the negative pressure rating of the breathing valve, the outside air is sucked into the API Std 650 insulated tanks through the open vacuum valve, which is the "suction" process of the oil tank.
