API Std 650 welded steel storage tanks subcontractors

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 floating roof is the top cover floating on the liquid level, so the sealing performance of API Std 650 welded steel storage tanks API 650 oil storage tank is very important. The floating plate mainly adopts elastic packing, and at the same time, it is compressed with the wall of API 650 oil storage tank with pressure strip around, and fixed with the floating plate with bolts. After the API Std 650 welded steel storage tanks floating plate is lowered to a certain position of about 1.8m, a prop will support the floating plate to keep it in position.

3500 tons SA387GR5CL1 steel plate to make pressure vessel equipment in Pakistan. The main business of our this client from Pakistan is manufacturing Columns&Towers, Heat Exchanger,Waste Heat Recovery Boiler, Pressure Vessel&Reactors,Tanks, Metering Skid. And we supply API Std 650 welded steel storage tanks the Mill Certificate, Shipping picture, the marking of steel plate and we help client to do SGS inspection.

Unqualified welding quality of API Std 650 welded steel storage tanks is prone to hidden dangers such as oil tank steel plate cracks and leakage. To avoid this situation as much as possible, it needs to be avoided when the oil storage tank is manufactured. Scientific and reasonable measures are adopted to control the welding quality when welding the API Std 650 welded steel storage tanks. How to reasonably control the welding process quality of oil storage tanks?

The after-sale service of iron and steel products includes after-sale tracking service, technical guidance, transfer of relevant bills, handling of objections and many other contents. The handling of quality objections accounts for a large proportion. When dealing with these problems, we should distinguish the responsibilities, and compensate or return the inconvenience or loss caused to users due to steel.
