All industries
Chemical Processing
Materials and constructions selected for aggressive chemistries and demanding pressure-temperature duty.
Use cases
- Reactor heating and cooling
- Solvent condensing
- Acid and caustic services
- Inter-stage cooling
Recommended products
- Gasketed Plate Heat ExchangerHigh-efficiency plate-and-frame units with serviceable gaskets.
- Fully Welded Plate Heat ExchangerGasket-free plate construction for aggressive media and high temperature.
- Welded Plate-and-Block Heat ExchangerWelded plate-and-block heat exchanger with removable side panels for inspection and cleaning.
- Shell and Tube Heat ExchangerRobust pressure-vessel design for high pressure and a broad fluid range.
- Heat Exchanger Gaskets, Plates & Spare PartsPlate heat exchanger gaskets, replacement plates and frame accessories.
Typical operating conditions
- Process media: solvents, acids, caustics, brines, reactor loops
- Temperature range: -30 to 200 °C (higher on request for welded units)
- Design pressure: typically 10–40 barg, plate or shell & tube
- Flow rates: 5–500 m³/h per unit, single- or multi-pass
Common engineering challenges
- Chloride and acid stress corrosion on stainless surfaces
- Fouling from polymerization, scaling or particulate carryover
- Thermal shock during batch heating/cooling cycles
- Chemical compatibility of elastomer gaskets with process media
Recommended materials & construction
- AISI 316L / 254 SMO plates for chloride-bearing services
- Titanium Gr.1 / Gr.2 for strong acids and seawater cooling
- Hastelloy C-276 / Nickel 200 for aggressive process duties
- EPDM, NBR, HNBR or FKM gaskets matched to media and temperature
Typical delivery scope
- Thermal and hydraulic sizing based on client duty sheet
- Material and gasket selection with corrosion review
- Fabrication under ASME / PED / CE (as specified)
- Hydrotest, dimensional check, nameplate and documentation package
Ranges shown are indicative for this industry. Actual design is confirmed per project against your duty sheet.
