Tank Body/Cylinder: Temperature Range -20°C to 200°C

Component Specifications

Definition

The tank body/cylinder is the primary structural component of an impregnation tank, designed as a cylindrical pressure vessel that contains the impregnation medium under controlled pressure and temperature conditions. It provides the sealed environment necessary for forcing impregnating materials into porous substrates through vacuum-pressure cycles.

Working Principle

The cylindrical tank body operates on pressure vessel principles, maintaining structural integrity under alternating vacuum and positive pressure cycles. During impregnation, the vessel is evacuated to remove air from porous materials, then pressurized to force impregnating resins or solutions into the substrate pores. The cylindrical shape provides optimal stress distribution under pressure.

Materials

Stainless steel 316L (ASTM A240/A240M), carbon steel with epoxy lining (ASTM A516 Gr.70), or specialized alloys for chemical resistance. Wall thickness: 10-50mm depending on pressure rating.

Frequently Asked Questions

What pressure rating is required for impregnation tank cylinders?

Typically 0-15 bar range with vacuum capability down to 0.95 bar absolute. Specific requirements depend on the impregnation process and materials being treated.

Why is stainless steel commonly used for impregnation tank bodies?

Stainless steel (especially 316L) offers excellent corrosion resistance against various impregnating chemicals, maintains cleanliness, and provides durability for repeated pressure cycles.

How are impregnation tank cylinders tested for safety?

Hydrostatic pressure testing at 1.5 times maximum allowable working pressure (MAWP), non-destructive testing (NDT) including ultrasonic thickness testing, and visual inspection per ASME standards.
