Mitundu yocheperako{{4} (<1.6 MPa) are typically used in gas pretreatment or cryogenic systems; medium-pressure types (1.6–10 MPa) are widely used in conventional chemical processes; and high-pressure types (>10 MPa) amagwiritsidwa ntchito nthawi zambiri pazinthu zovuta kwambiri monga kupatukana kwa cryogenic ndi high-pressure hydrogenation.

Gulu ndi Ntchito
In industrial applications, spiral wound heat exchangers can be categorized as conventional process, cryogenic, and high-temperature and high-pressure types. Conventional process types are used for general heat exchange needs, such as hot water or low-pressure steam systems. Cryogenic types are designed for ultra-low-temperature media such as liquefied natural gas (LNG) or liquid nitrogen, utilizing specialized insulation and cryogenic materials. High-temperature and high-pressure types serve high-temperature (>400°C) and high-pressure (>20 MPa) malo, monga kung'amba kwa petroleum ndi kaphatikizidwe ka ammonia, kutsindika kukana kwa dzimbiri komanso kukhazikika kwamapangidwe.
