Products Description

Industrial Welded Spiral Plate Heat Exchanges are manufactured by rolling two metal sheets to form spiral flow channels. All channel edges are fully sealed via welding with no rubber gaskets, making them suitable for harsh high-temperature and high-pressure working environments. Hot and cold media flow counter-currently through separate spiral channels for sufficient heat exchange. The fluid generates strong turbulence, delivering far higher heat transfer efficiency than shell-and-tube equipment. Plates can be fabricated from stainless steel, carbon steel and other materials to resist oil contamination, acid and alkali corrosion. The self-cleaning flow channels resist clogging and simplify inspection and maintenance. Featuring a compact structure that occupies only one-third of the floor space required by traditional heat exchangers, they are widely applied in chemical, grease, HVAC, metallurgical and waste heat recovery industries. They can process steam, thermal oil, corrosive liquid materials and other media with stable temperature and pressure resistance, supporting long-term stable operation on continuous industrial production lines.

Product Advantages

Anti-Clogging Performance

The unique spiral channel design reduces impurity deposition and clogging risks, making it compatible with media containing minor solid particles.

High Pressure Resistance

The fully welded monolithic structure withstands high operating pressures to meet the requirements of most high-pressure industrial production scenarios.

Industrial Welded Spiral Plate Heat Exchanges

Zero Leakage Risk

Traditional sealing gaskets are eliminated in favor of full welded sealing, fundamentally lowering the potential risk of medium leakage.

Efficient Heat Transfer

Media creates turbulent flow inside channels, greatly boosting heat transfer efficiency and minimizing energy loss during heat exchange.

Process Technology

Full Welded Forming

Mature integral welding technology guarantees robust overall structural strength and prevents structural loosening during operation.

Rolled Plate Forming

Specialized rolling processes produce uniform, regular spiral channels to maintain stable fluid flow conditions.

Surface Treatment

Special protective surface treatment improves corrosion resistance and extends the equipment's overall service life.

Non-Destructive Testing

Multi-stage non-destructive testing procedures detect potential internal defects to ensure reliable equipment operation after delivery.

Precautions

Prevent large foreign objects from entering internal flow channels, as they may scratch inner walls and degrade heat transfer performance.

Do not operate the equipment outside its rated working conditions to avoid structural deformation or leakage.

Avoid sudden exposure to media with extreme temperature differences, which may trigger structural cracking from abrupt thermal stress shifts.

Do not introduce highly corrosive media directly without prior confirmation of compatibility between the media and equipment materials.

Avoid heavy impact or knocking around the equipment to prevent hidden cracks at weld seams that may cause leakage.

Q: Are Industrial Welded Spiral Plate Heat Exchanges prone to clogging during regular use?

A: Clogging rarely occurs. Continuous spiral flow channels enable high-velocity turbulent fluid to scour plate surfaces without dead zones where impurities accumulate. Viscous fluids and liquids with minor impurities barely form scale deposits, so frequent shutdowns for cleaning are unnecessary under normal operating conditions.

Q: Will heat exchange performance gradually decline after 24-hour continuous operation?

A: Heat exchange efficiency remains stable long-term under standard media conditions. The spiral counter-flow structure ensures uniform heat distribution and eliminates local overheating that impairs efficiency. Heat transfer capacity will not drop noticeably as long as the media does not carry large volumes of stubborn sediment.

Q: Do Industrial Welded Spiral Plate Heat Exchanges produce loud operating noise?

A: Operating noise is extremely low. Fluid flows and turns gently inside spiral channels without violent impact or vibration. The equipment runs quietly inside production workshops, and harsh noise will not disrupt surrounding production activities.

Q: What service life can be expected when handling corrosive fluids?

A: The equipment is well-suited for corrosive media applications. Plate materials resist acid and alkali erosion, and the fully welded sealed structure eliminates crevice corrosion points to stop media infiltration into equipment interlayers, enabling a long service life under normal operation.
