Shop assembly of API 650 partially anchored liquid-storage tanks

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 partially anchored liquid-storage tanks tank. Tap one inch NPT test hole in each pad or section.

API 650 partially anchored liquid-storage tanks foam generator is a fire extinguishing device fixed on the oil tank. One end of the foam generator is connected to the foam pipeline, and one end is flanged on the top layer of the API 650 partially anchored liquid-storage tanks wall. Fire extinguishing foam flows through the air intake entrance of the fire foam chamber, inhaling a large amount of air to form foam, and breaking through the insulating glass into the tank (glass thickness is not greater than 2mm), so as to achieve the purpose of fire fighting.

In this project, the area of tank wall used is of the same construction, material, and geometry as that described in F.1.3.1 except that the thickness of the plate is 3/8 in. The wall is stressed in the same manner as is described in F.1.3.1. A corrosion allowance of 1/16 in. is required. The computed (meridional) tensile stress, stc, in the net thickness after deduction of the corrosion allowance is 8000 lbf/in.2.
The problem in this example is to find the maximum allowable (latitudinal) compressive stress value for the given conditions, in conformance with the provisions of API 620 tank standard 5.5.4.5.
Solution: As determined from Table 5-1, the maximum allowable tensile stress value, Sts, for ASTM A285, Grade C, steel plate in simple tension is 16,500 lbf/in.2. Since the compressive stress is latitudinal, the governing value of R in this situation is R1, or 75 in.

The impression of most customers who have cooperated with us on the company is being professional and responsible. That mainly owe to our united and considerate team members. For example, the professional technician, the responsible QC inspector, the experienced sales person, the rigorous document maker, the patient after-sales, etc. Their selfless devotion bring the customer good experience, and bring the company good reputation.

Tianjin warehouse mainly stores steel plates and steel pipes. The monthly replenishment is about 12000 tons. Our inventory cycle is short and flexible. Shanghai warehouse mainly stores API 650 partially anchored liquid-storage tanks ,steel plate and section steel. The average monthly purchase volume is about 15000 tons. The geographical location of the warehouse has greatly improved our performance in terms of transportation and delivery time.
