CSA G40.21 Gr 350WT plates API standard 650 stainless and carbon steel tank

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 internal floating plate of internal floating roof tank of API 650 tank is different from that of open floating plate of API standard 650 stainless and carbon steel tank External floating roof tank of API 650 tank, so it is impossible to have rain and snow load.We have built solid cooperation with Myanmar Navy since 2015, starting from a try order about 412 tons LR AH36 shipbuilding steel plates. Myanmar navy builds frigate every year and book shipbuilding steel materials from us regularly. This time, the Myanmar navy’s local representative visit us and put another order about 2025 tons LR grade A steel plates. According to clients requirements, we arranged API standard 650 stainless and carbon steel tank SGS inspection for the LR grade A steel plates before shipping and send them inspection report.According to the standard of head of API standard 650 stainless and carbon steel tank, there should be no crack, delamination, inclusion and other defects on the groove surface, which is consistent with the steel plate standard. The API standard 650 stainless and carbon steel tank head polishing can adopt different technology according to different requirements, including rough polishing, medium polishing and fine polishing. Only the materials used for the third type of pressure vessels must be retested, and the materials used for the first and second class pressure vessels are not generally re inspected.With a high-quality and complete after-sales service system, the company solves the user's hindrance and improves the reliability of steel API standard 650 stainless and carbon steel tank product quality. Reaching every corner of the globe with professional services, users anywhere can get thoughtful and detailed services form us is our pursue. We promise all our steel materials are manufactured and tested in accordance with responding standards. We will take full responsibility for the quality of the steel materials we provide.
