API standard 650 low-alloy steel tanks seismic use group ii

Welded steel API standard 650 low-alloy steel tanks storage tanks that are designed, manufactured and installed on the ground are classified according to the API standard system. The three API standards API standard 650 low-alloy steel tanks all adopt on-site production and installation of storage tanks.

In this project, a cylindrical tank 62 ft 6 in. in diameter is designed for an internal pressure of 4 lbf/in.2 gauge in the vapor space. The plate material is ASTM A131 steel with appropriate grades for different plate thicknesses in accordance with Table 4-1 for a design metal temperature less than 65°F but not less than 25°F. No corrosion allowance is required for any portion of the tank. The top course of the butt-welded cylindrical sidewall is 1/4 in. thick. The roof is a single lap-welded spherical dome with an internal radius of 50 ft and a thickness of 1/4 in. The maximum design liquid level is 6 in. below the plane of the juncture of the tank API standard 650 low-alloy steel tanks roof and sidewall.

As we know, the vertical metal tank, API standard 650 low-alloy steel tanks is welded by many components, and the welding quality of each component determines the later use effect of the API standard 650 low-alloy steel tanks. Professional API standard 650 low-alloy steel tanks manufacturers should have a set of professional skills in the welding process of API standard 650 low-alloy steel tanks. Key points for weld inspection of vertical metal tank, API standard 650 low-alloy steel 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.

Enterprise mission: to create value added steel products API standard 650 low-alloy steel tanks and provide first-class serviceWe are committed to quality. It is to firmly establish the concept that quality is the life of an enterprise, and make it clear that quality is the decisive factor for the survival and development of an enterprise. Adhere to the quality brand strategy and strive to improve the comprehensive competitiveness with quality as the core.Core values of the enterprise: innovation, dedication and transcendence.

Box making, door-to-door: fill in the packing plan: box making time, ship name, voyage number, customs declaration number, transfer port, destination port, gross weight, number of pieces, volume, door point, contact person, telephone number, etc., and arrange the train shift 1-2 days before the closing date (two days before the ship's date). Internal loading: fill in the packing plan: ship name, voyage number, customs declaration number, transfer port, destination port, gross weight, number of pieces, volume, cabin number, etc., and arrange the train shift 1-2 days before the closing date (two days before the ship's date).

Compared with other fast-moving consumer goods, steel consumption is obviously different, with a wide range of use and a long service life. Therefore, the quality and service of steel materials are particularly important. Service is always one of our top concerns, especially after-sales service. We have mature after-sales service team, and can help you solve problems professionally during application of the steel materials.
