aluminum sheet 5050 API 650 low-alloy steel tanks

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.

Welding certification is regulated by Section 10 of the American Society of Mechanical Engineers (ASME). For both API 650 low-alloy steel tanks storage tank API 650, non-destructive inspection is required, but third-party inspection is not required.

In April 2018, our Philiphine customer purchased 1008 Tons API5 L Gr.B ERW&Q345B SMLS pipe API 650 low-alloy steel tanks for offshore oildfield resources drilling project. This is a regular demand almost two month, and we has been cooperated more than three times, totally around 2100 tons steel pipe since 2015 year.

Safety comparison between mechanical cleaning and manual cleaning of vertical storage tank, API 650 low-alloy steel tanks. Closed cleaning is adopted for mechanical cleaning. During the cleaning process, operators are not required to enter the tank. The inert gas space formed in the storage tank can prevent the occurrence of fire, explosion and other accidents. When the API 650 low-alloy steel tanks is manually cleaned, the operators should directly enter the tank for cleaning, threatening the health of employees, and there is no inert gas space in the tank, which is prone to fire and explosion accidents.
