Reactors and pressure vessels
Jacketed, limpet-coil and agitated reactors, pressure vessels, receivers and columns in carbon and stainless steel, designed to ASME Section VIII Division 1 or IS 2825.
- ASME VIII Div 1
- IS 2825
- Carbon and stainless steel

What we build
Built to your process conditions, from a simple receiver to a fully agitated, jacketed reactor.
Jacketed reactors
A full or partial jacket around the shell for heating or cooling with steam, thermic fluid, water or brine.
Limpet-coil reactors
A half-pipe coil welded to the shell, suited to higher jacket-side pressures, with good heat transfer.
Agitated reactors
Reactors with a top-entry agitator, shaft seal and drive matched to the batch. See agitators and mixing systems.
Reactors with internal coils
Internal heating or cooling coils where a jacket alone cannot meet the duty.
Pressure vessels and receivers
Process vessels, receivers and separators for liquids and gases under pressure.
Columns
Vertical process columns fabricated to your process design, with the nozzles and supports specified.
Design and construction
Defined by your datasheet and the applicable code.
- Design code
- ASME Section VIII Division 1 or IS 2825. Jackets and limpet coils are designed to the same code as the shell.
- Materials
- Carbon steel; stainless steel 304, 304L, 316 and 316L; duplex and other alloys as specified.
- Internal finish
- As-welded, ground or polished, including finishes for pharmaceutical and food service. Stainless steel is pickled and passivated.
- Openings and fittings
- Process nozzles, manways, sight and light glasses and instrument connections, as your datasheet requires.
- Supports
- Legs, lugs, saddles or skirt, to suit the installation.
- Insulation and cladding
- Supplied on request.
Testing and documentation
Recorded as the work progresses and handed over with the equipment.
- Hydrostatic test of the shell and of the jacket or limpet coil
- Dye penetrant examination of nozzle and attachment welds
- Radiography or ultrasonic testing where the code or your specification requires it
- Material test certificates and welding records
- Final data book with drawings, calculations and test certificates
Applications
Built for pharmaceutical and API plants; chemical and specialty chemical plants; food and dairy processing; and oil, gas and petrochemical projects.
