EN 10025 S355 plates API 650 SUG II tanks

Thickness as it Affects Preheat and Post-heat Requirements
Plate with thicknesses below 1/2 in. is reasonably notch tough. In most steels, when the API 650 SUG II tanks used plate thickness exceeds 3/4 in. – 1 in., notch toughness, particularly as welded, decreases sharply. The decrease in notch toughness can be minimized by the conventional post-heat treatment and, in many steels, by preheat treatment. The benefits of preheat treatment in steels 3/4 in. – 1 in. thick have been demonstrated; similar benefits could be expected in thicker steels, but sufficient experimental data are currently lacking.

For floating roof API 650 tanks, the net working capacity is the liquid volume contained between the API 650 SUG II tanks maximum operating level (300 mm below rim for metallic type seals and 600 mm below rim for fabric type seals) and the minimum operating level (API 650 tanks roof supports clearing the tank bottom by 25 mm while set at the operating position).

In 2016, we brought our customer to visit our NM400 hot rolled plate; producing line and our shanghai warehouse for 30,000 tons plate and structure. As a result, Our client purchased 500 tons NM400 as first order, which is shipped by 3 times. In future. Our company will always guarantee that all the delivery condition for Hardox plate API 650 SUG II tanks provided will be with quenching and tempering, which is the best delivery type according GB/T 24186 standard.

storage tank is used to store all kinds of liquid, solid and gas materials. The common types of storage tank are oil tank, water storage tank, chemical tank, cement tank, API 650 SUG II tanks, etc. When choosing the storage tank, users should choose according to their actual needs, such as the material, pressure, form, capacity, temperature, density, etc. In addition, the environmental factors such as the temperature of the tank construction area, the ground endurance of the foundation, and the wind force should be considered.

The company attaches great importance to the cultivation of team spirit. Personal strength is weak. After sales service departments, leaders and subordinates often communicate with each other. Everyone often holds meetings to discuss their problems in after-sales service, discuss technical difficulties, discuss how to improve work efficiency, how to better deal with user complaints, etc.
