Shell and tube heat exchanger

liquid/liquidwater/oilwater/water

Product Overview
Custom-engineered ASME- and PED-certified shell and tube heat exchangers for chemical, petrochemical and industrial manufacturing processes. TEMA-standard designs optimized for thermal efficiency in high-pressure, high-temperature environments.

Key Capabilities

• Custom thermal design: counterflow, parallel or crossflow; optimized baffle spacing, tube layout and pass configuration to maximize heat recovery efficiency.
• ASME & PED compliance: fabrication per ASME Section VIII and PED 2014/68/EU with full design calculations, material certificates and hydrostatic testing documentation.
• Engineered material selection: carbon steel, 304/316 stainless, duplex stainless, nickel alloys (Inconel, Hastelloy), titanium, copper alloys and other exotic materials as required.

TEMA Configurations

• Fixed Tubesheet (BEM, AEL, NEN): economical design with tubes welded to tubesheets fixed to both shell ends. Ideal for clean services where shell-side mechanical cleaning is not required.
  • Lowest cost per heat transfer area
  • Simple, rugged construction
  • Tubeside mechanically cleanable
  • Suitable for similar shell/tube temperatures
  • Maximum surface in given shell diameter
  • Optional expansion joint for thermal stress
  • TEMA class BEM, AEL, NEN
• U-Tube Bundle (AEU, BEU): single tubesheet with U-bent tubes allowing thermal expansion; bundle removable for shell-side cleaning without disturbing piping.
  • Accommodates thermal expansion
  • Removable tube bundle
  • No expansion joint required
  • Shell-side accessible for cleaning
  • Lower cost than floating head
  • Limited to even tube passes
  • Tubeside cleaning more difficult
• Floating Head (AES, BES, AET, BET): one tubesheet fixed, one floating to accommodate differential expansion; allows complete mechanical cleaning of both shell and tube sides.
  • Handles high thermal differentials
  • Both sides mechanically cleanable
  • Removable tube bundle
  • Suitable for fouling services
  • Any number of tube passes
  • Higher cost than fixed or U-tube
  • TEMA S, T, P, W rear heads

Applications

• Chemical & petrochemical: process cooling, reactor temperature control, condensers, reboilers, heat removal and product heating.
• Oil & gas refining: crude preheat, product coolers, intercoolers, vaporizers and heat recovery.
• Pharmaceutical: API synthesis control, solvent recovery condensers, bioreactor cooling, WFI heat exchangers.
• OEM integration: custom exchangers for process skids, modular plants and packaged systems.
• Power generation & renewables: condensers, feedwater heating, lube oil cooling, biogas/biodiesel/biomass heat recovery, geothermal and solar thermal applications.
