A537Cl1 plates API Std 650 SUG III tanks

API 650 petroleum storage tank has the advantage of long economic life: because there is no gas space on the liquid surface in the internal floating roof API Std 650 SUG III tanks storage tank, the vibration generated during the transportation of liquid inside and outside the tank is reduced.

In order to prevent the deformation of the bottom of metal vertical API Std 650 SUG III tanks during welding, comprehensive control measures such as strict control of assembly geometry size, reasonable welding procedure, process control of welding deformation and rigid fixation are adopted during assembly welding. The specific methods are as follows:
1. Strictly control welding groove forming of API Std 650 SUG III tanks.
2. Strictly control the size of tank welding seam assembly.
3. Define the welding sequence of tank bottom plate.
4. Reasonable distribution of welders.

In this project a cylindrical tank 75 ft in diameter is designed for an internal pressure of 0.5 lbf/in.2 gauge in the vapor space. The plate material is ASTM A131 Grade B steel for thicknesses of 1/2 in. and less.
The top course of the butt-welded cylindrical sidewall is 1/4 in. thick. The tank API Std 650 SUG III tanks roof is a conical shape with a 2:12 slope and a 1/4 in. thickness with single full-fillet welded lap joints. The maximum design liquid level is 6 in. below the plane of juncture of the roof and sidewall.

The quality inspection department is responsible for the inspection management of raw materials and finished products, and the quality inspection and acceptance of products and raw materials. Strictly abide by the company's management system, conscientiously exercise the management power given by the company, and put an end to all ultra vires; be responsible for the inspection of all kinds of raw materials entering the company, and put forward quality problems and handling opinions.

Management information and high efficiency. Because of the rapid flow of API Std 650 SUG III tanks goods, container multimodal transport and "door-to-door" transport, it is required that the port must have a modern information network, so that it can have the comprehensive capabilities of all-weather access, rapid loading and unloading, customs clearance, collection, distribution, storage and transportation
