A53 grade A pipe API Std 650 low-alloy steel tanks

API 650 can store oil, gas, chemical, water and biofuel for some of the most common tanks in the oil industry. API 650 can store contents at a lower pressure (maximum of 2 PSI) but at much higher temperature (-40 degrees F to 500 degrees F) than the standards of API Std 650 low-alloy steel tanks. It can be any tank size.

To scientifically evaluate the remaining service life of the API Std 650 low-alloy steel tanks, it is necessary to know the thickness change and development trend of the storage tank sheet after long-term use, combined with the metal characteristics of the storage tank, the influence of various external conditions and the continuous change of the oil pressure in the API Std 650 low-alloy steel tanks, etc. factors to judge. Because the metal characteristics, corrosion defects, load and other numerical parameters of the API Std 650 low-alloy steel tanks are randomly changed, the value of the remaining service life of the storage tank will also be dynamic.

A cylindrical nozzle with a 12-in. inside diameter is located in solid plate in the sidewall of a cylindrical storage tank 60 ft in diameter so that its axis lies in a horizontal plane and forms an angle of 55° with a perpendicular to the sidewall at the point of intersection, as shown in Figure F-7. The thickness of the API Std 650 low-alloy steel tanks sidewall plate, tw, in this area is 5/8 in., and no corrosion allowance is required. The total internal pressure, Pl + Pg, at the center of the opening is 26.1 lbf/in.2 gauge.

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;

Booking space and making power of attorney (ten copies of order); the data of the original order shall be correct and consistent to the greatest extent when making the order, so as to reduce the frequent changes in the subsequent process. For booking with the company's seal for booking space, if the accessories for booking space (such as the price confirmation document of the shipping company) need to be provided, they can only be booked with all of them. Obtain the shipping space allocation receipt and extract the ship name, voyage number and B / L number information.
