API Std 650 aboveground petroleum storage tanks bottom-transition plate
One of the most widely used design codes is the API 650 Standard, from the American Petroleum Institute. The main objective of this standards API Std 650 aboveground petroleum storage tanks is, through the requirements contained in its various sections, to facilitate the purchase and construction of vertical, aboveground, welded fabricated tanks assuring that required safety regulations are met.
Atmospheric API Std 650 aboveground petroleum storage tanks inspection includes annual inspection and comprehensive inspection. Annual inspection is an inspection during operation to ensure the safety of atmospheric storage tanks during the overhaul period, at least once a year. Comprehensive inspection is a more comprehensive inspection of atmospheric storage tanks according to a certain inspection cycle. The inspection content of metal atmospheric API Std 650 aboveground petroleum storage tanks includes the safety management of the storage tank, the inspection of the tank body and its operating conditions, etc.
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.
Our company's technical department is the core department of the whole company. There are a group of very professional technical personnel. They provide some architectural drawings according to the ideas of customers, and they are responsible for how to select the right materials. Including the evaluation of steel products such as multi steel plate, API Std 650 aboveground petroleum storage tanks and steel pipe, grasp the whole production process, and strictly follow the production standards and customer quality requirements.
The company's logistics department has the ability to monitor the whole process of logistics. We monitor the goods in transit through advanced information technology and communication technology, timely discover and handle problems in the transportation process, and ensure the steel materials are delivered to the destination in a timely and safe manner. The professional logistics team provides powerful support for good comments of customers and good reputation of the company.
