Fully Welded Plate Heat Exchanger
A fully welded plate heat exchanger uses a permanently welded corrugated plate pack instead of gasketed heat-transfer channels. The structure improves containment for demanding fluids while retaining compact plate heat-transfer performance for petrochemical, refining, chemical, pharmaceutical, power, geothermal, and high-purity process duties.

When to select it
Select this design when leakage containment, high pressure, high temperature, corrosion resistance, or reduced gasket maintenance matters more than full mechanical access to every channel.
Engineering focus
A project should confirm pressure rating, temperature program, material compatibility, thermal expansion, cleaning method, welding quality requirements, and final hydrostatic testing.
Key Advantages
Gasket-free heat-transfer core reduces external leakage points and gasket replacement work.
Welded corrugated plate channels deliver high heat-transfer efficiency in a compact footprint.
Suitable for hazardous, high-value, corrosive, high-pressure, and high-temperature media when matched with proper materials.
Lower routine maintenance demand supports continuous process lines.
CIP cleaning and inspection planning can be matched to the fouling behavior of the process fluid.
Material options support stainless steel, titanium, Hastelloy, and other corrosion-resistant alloys.
