Equipment Requirements

General requirements for static equipment

The size of the static equipment included in this project should be proportionally reduced according to industrial equipment and adjusted based on the principle of coordinated aesthetics. The equipment structure should be consistent with industrial equipment. The detailed requirements are as follows:

①static equipmentmaterialselectstainless steelMaterial, equipment wall thickness not less than1.5mmMeet the installation and usage requirements.

②equipmentmanufactureThe variety, specifications, and properties of the steel used in the product comply with current standardsrelatedStandards and design requirements.

③ EquipmentassemblyThe varieties, specifications, performance, etc. of flanges, fittings, valves, etc. used in the product comply with current productsrelatedStandards and design requirements.

④ The variety, specifications, performance, etc. of fastening standard components such as connecting bolts of the equipment shall comply with the productrelatedStandards and design requirements.

⑤ The variety, specifications, and performance of the welding materials used in the equipment comply with the current productsrelatedStandards and design requirements.

⑥ The equipment usedshimThe variety, specifications, and performance of special materials should comply with the current standardsproductrelatedStandards and design requirements.

⑦ Considering the relative size of the height (length) and diameter of each device,criticalityModerately increase the diameter of the equipment to highlight the main equipment. Especially for the main equipment, the aspect ratio should be kept within a moderate range to ensure a coordinated appearance of the equipment.

General requirements for tower equipment

Considering that tower type equipment may be highly valued in practical installationsStrictly scaling down in proportion may result in excessive height or tower diameter being too small, in which caseModerately increase the diameter，But it is necessary to consider the appropriate aspect ratio.

The tower equipment of the same device needs to reflect the difference in relative dimensions of the equipment, and the minimum tower diameter shall not be less than150mm， The maximum height of the tower shall not exceed 4m.

General requirements for cold exchange equipment

（1）The external dimensions of the cold exchange equipment should be consistent with those of industrial equipment, and the equipment dimensions should reflect the differences in heat exchange capacity.

（2）The appearance of the cold exchange equipment should reflect the form of the heat exchanger, and the selection of the heat exchanger should be consistent with the industrial equipment, covering as many types of heat exchange equipment as possible.

（3) The design of fluid inlet and outlet ports should comply with process requirements and the rationality of actual operation; The flow direction of liquid phase fluid must be bottom in and top out, while materials that need to be condensed in the gas phase must be in and out.
