A106 grade A pipe API Std 650 mixed material tanks
The API 650 is the American standard for welded flat-bottomed vertical API Std 650 mixed material tanks storage tanks. This standard dictates tank design, manufacture, welding, inspection and installation requirements.
API Std 650 mixed material tanks Breathing valve: The function of the oil tank breathing valve is to adjust the oil and gas pressure in the tank. When the pressure in the tank is too high, part of the excess oil and gas will be discharged through the breathing valve to reduce the pressure in the tank; when the pressure in the tank is too low, through breathing The valve sucks in air from the outside of the tank to increase the pressure in the tank and keep it constant with the atmospheric pressure. The breathing valve is usually installed at the top of the oil tank.
Allowable Design StressesThe maximum allowable design stresses for the API Std 650 mixed material tanks materials outlined in Q.2.1 shall be in accordance with Table Q-3.The values for the allowable design tensile stress given in Table Q-3 for materials other than bolting steel are the lesser of (a) 331/3% of the specified minimum ultimate tensile strength for the material or (b) 662/3% of the specified minimum yield strength, but they are 75% of the specified minimum yield strength for the stainless steel, nickel alloy, and aluminum materials. Allowable test stresses are based on the limitation of API 620 oil tank storage standard Q.8.1.3.
Every after-sales service shall have a detailed record of the customer's product problems and handling methods. The records shall be sorted into volumes and filed on a monthly basis, and submitted to the technical department for filing. The problems found in the after-sales service shall be summarized in a timely manner, discussed with the technical department, the quality inspection department and the production department, and a proper solution shall be proposed for the technical department to improve in a timely manner;
Land transportation inquiry: (RMB fee) it is required to master the kilometers and towing price of major cities; packing price of each port area; customs clearance fee, commodity inspection fee, and animal and plant inspection fee standard. Key information to be clarified after accepting the consignation of the consignor (generally fax): shipping date, number of packages, box type, box quantity, gross weight and volume.
