High Temperature/Pressure Semi-Welded Plate Heat Exchanger for Metalworking and Steel Production/Power Generation and Thermal/Chemical Plants

Product Description

Product Description

1. Introduction
The semi-welded plate heat exchanger is a highly efficient heat exchange device that combines welding technology with gasket sealing. Its structure consists of two plates welded together to form sealed channels, while adjacent channels are sealed using gaskets. This design avoids the potential metal fatigue issues associated with fully welded exchangers, while also overcoming the temperature and pressure limitations of traditional gasketed units. It is particularly suitable for applications involving media with particles or fibers, as it effectively prevents clogging.

The semi-welded plate heat exchanger offers high heat transfer efficiency, a compact structure, and flexible operation. It is widely used in industries such as chemical processing, food and beverage, and pharmaceuticals, and is especially ideal for applications requiring higher operating temperatures and pressures.

2. Key Features
a. Hybrid Sealing Design: Combines welded and gasketed channels to balance durability and maintenance convenience.
b. Enhanced Pressure and Temperature Resistance: Suitable for demanding applications with higher thermal and pressure requirements.
c. Clog-Resistant Flow Paths: Welded channels are ideal for media containing particles or fibers, reducing the risk of blockage.
d. High Heat Transfer Efficiency: Corrugated plate design maximizes surface area and thermal performance.
e. Compact and Flexible Structure: Space-saving design with easy expansion or plate replacement.
f. Reduced Risk of Metal Fatigue: Partially welded structure helps avoid stress issues found in fully welded designs.

3. Applications
a. Chemical Industry – Handling aggressive or high-viscosity media, especially with particles.
b. Food and Beverage Processing – Suitable for fiber-rich liquids and pasteurized fluids.
c. Pharmaceutical Industry – For processes requiring sanitary design and reliable thermal control.
d. Pulp and Paper Industry – For fiber-containing slurries or heat recovery from waste streams.
e. Industrial Cooling and Heating – Where high temperature and pressure stability are essential.
f. Marine and Offshore Systems – Durable performance in harsh or variable conditions.
