Spiral Plate Heat Exchanger

Spiral Plate Heat Exchanger

Product Overview

Spiral plate heat exchangers are a type of heat exchange equipment suitable for gas-gas, gas-liquid, and liquid-liquid applications, as well as for condensation and liquid evaporation heat transfer. This product boasts high heat transfer efficiency, strong self-cleaning ability against scale, compact size, affordability, and reliable operation. It is used in industries such as chemicals, petrochemicals, solvents, food, light industry, textiles, metallurgy, rolling steel, and coking. They can be categorized into non-disassemblable (Type I) and disassemblable (Type II, III) spiral plate heat exchangers based on their structural design.

The nominal pressure PN for spiral plate heat exchangers is specified as 0.6, 1, 1.6, and 2.5 MPa (equivalent to the original 6, 10, 16, and 25 kg/cm²), referring to the working pressure that a single channel can withstand. The test pressure is 1.25 times the working pressure.

Basic Parameters

The material for the contact part of the spiral plate heat exchanger with the medium is carbon steel Q235A, Q235AF, and stainless steel acid steel SUS321, SUS304. Other materials can be selected according to customer requirements.

 Allowable working temperature: carbon steel t=0～+350℃，stainless steel and acid-resistant steel t=-40～500℃，the range of temperature rise and pressure reduction shall comply with the relevant regulations for pressure vessels. When selecting this equipment, appropriate process calculations should be made to ensure the fluid in the equipment channel reaches turbulent flow. (Generally, liquid velocity is 1m/Sec, gas velocity is 10m/Sec).

  A single unit does not meet the usage requirements; multiple units can be combined for use. However, the following regulations must be adhered to when combining them:

Parallel and Series Combinations: Same spacing between equipment and channels.

Mixed Combination: One channel in parallel, one channel in series.
