ISO 630 Gr E275C plates API Std 650 flat-bottom tanks
Tanks which are designed following rules and guidelines of API 650 are API 650 tanks. API 650 API Std 650 flat-bottom tanks is the governing code for Welded tanks for Oil storage normally operating in the atmospheric pressure range. The code API 650 provides guidelines for design, fabrication, material, erection, and inspection of welded vertical and cylindrical storage tanks. Such API Std 650 flat-bottom tanks Tanks must be above ground with a closed or open top.
In this project, an area of tank wall is constructed of ASTM A285, Grade C, steel plate that is 5/8-in. thick and has spot-radiographed, double-welded butt joints. The wall is subject to tension in a meridional direction and to compression in a latitudinal direction. The values of R1 and R2 at the point under consideration are 75 in. and 300 in. respectively. 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 6000 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.
As we know, the vertical metal tank, API Std 650 flat-bottom tanks is welded by many components, and the welding quality of each component determines the later use effect of the API Std 650 flat-bottom tanks. Professional API Std 650 flat-bottom tanks manufacturers should have a set of professional skills in the welding process of API Std 650 flat-bottom tanks. Key points for weld inspection of vertical metal tank, API Std 650 flat-bottom tanks: 1. It is strictly forbidden to paint the welds before passing the inspection. 2. Visual inspection shall be carried out for welds. 3. NDT shall be carried out on the weld.
Aspire to technological innovation and pursue first-class quality steel API Std 650 flat-bottom tanks products.Take independent innovation as an important support for the sustainable development of iron and steel industry, strengthen the main position of technological innovation, accelerate the original innovation, integrated innovation, introduction, digestion, absorption and re innovation, improve the technological innovation system, and cultivate the core technology and brand products of independent intellectual property rights.
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 Std 650 flat-bottom 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.
The 365 day service system is implemented, and the business, loading and delivery are handled as usual in holidays and festivals. Actively help users solve difficulties. When users encounter difficulties in handling business, they should actively coordinate with the external solution; if they need to solve the problems internally, they should solve them in a timely manner without prevarication and wrangling. In line with the API Std 650 flat-bottom tanks principle of "fairness, justice and timeliness", coordinate with relevant departments and deal with all kinds of objections in a timely manner.
