Non-disassemblable horizontal spiral plate heat exchanger
Product Overview
Spiral plate heat exchangers are heat exchange devices 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 fouling, compact size, affordable price, and reliable operation. It is used in industries such as chemicals, petrochemicals, solvents, food, light industry, textiles, metallurgy, rolling steel, and coking. Spiral plate heat exchangers can be classified into non-detachable (Type I) and removable (Type II, III) 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 acid steel SUS321, SUS304. Other materials can be selected according to customer requirements.
Operating Temperature Range: Carbon steel: t=0～+350°C, stainless steel and acid-resistant steel: t=-40～500°C, the temperature and pressure reduction range shall comply with the relevant regulations for pressure vessels. When selecting this equipment, appropriate process calculations should be performed to ensure the fluid in the equipment passage reaches turbulent flow conditions. (Typical liquid flow rate: 1m/sec, gas flow rate: 10m/sec).
A single unit does not meet the usage requirements; multiple units can be combined for use, but the combination must comply with the following regulations:
Parallel and Series Combinations: Same spacing between equipment and channels.
Mixed Combination: One channel in parallel, one channel in series.
