Shell & tube heat exchangers — HTRI thermal design to fabrication

Heat transfer, engineered end to end.

Shell & tube heat exchangers of every TEMA type are a core Steelcon product — thermally designed and rated with HTRI, mechanically designed to TEMA and ASME Section VIII, and built with the tube-to-tube-sheet, expansion and testing disciplines that exchangers demand. From a single condenser to multi-tubular reactors with thousands of tubes, in carbon steel, stainless, duplex, nickel alloys or clad construction.

Thermal to mechanical, under one roof

Thermal design & rating

Thermal design and rating with HTRI for single-phase, condensing and boiling duties — pressure drop, vibration and fouling checks included — from your process data or your licensor's datasheet.

Mechanical design

TEMA Classes B, C and R and ASME Section VIII; tube-sheets, flanges, expansion joints and supports calculated and verified in PV Elite and COMPRESS; nozzle loads and transport checked.

Materials

Carbon and low-alloy steels, stainless, duplex and super-duplex, Inconel, Hastelloy and other nickel alloys; explosion-bonded clad tube-sheets and channels; plain, corrugated or finned tubes.

Fabrication

Tube-to-tube-sheet joints strength- or seal-welded and expanded with in-house expanders; U-bends heat-treated after trials on samples for each radius; baffle cages, tie-rods and impingement plates built to drawing.

Testing & documentation

Shell-side and tube-side hydro tests held for one hour; pneumatic checks before expansion; PMI on all non-carbon-steel parts; IBR-approved for exchangers; full dossier with the equipment.

Exchangers in service

Re-tubing, bundle replacement, tube plugging, re-rating and repairs under our National Board R certificate — for exchangers from our works or from elsewhere.

Every TEMA type, built to the tube

Fixed tube-sheet

BEM / NEN — with expansion joints where the design needs them

U-tube

BEU / AEU — removable bundles for high-pressure and clean tube-side fluids

Floating head

AES / BES / AET — pull-through and split-ring designs for fouling services

Kettle reboilers

AKT / BKU — vapour disengagement space and weir designed for the duty

Condensers & reboilers

Vertical and horizontal condensers, vent condensers, thermosyphon and forced-circulation reboilers

Evaporator calandrias

Multiple-effect evaporator calandrias and column-mounted exchangers

Multi-tubular reactors

Formaldehyde and catalytic tubular reactors — to 3.5 m diameter and 8,800 tubes

Double-pipe & coil

Double-pipe and hairpin exchangers; internal, limpet and outside coils

Configurations

What to tell us about your duty

A thermal datasheet is ideal. If you are starting from the process, these points let our engineers propose a design in the first reply.

The duty Fluids on each side, flow rates, inlet and outlet temperatures, allowable pressure drops, fouling factors — or simply the process datasheet.

Design data Design and operating pressure and temperature for each side, TEMA class, construction code and stamping requirement.

The geometry TEMA type, tube OD and count if known, tube type and pitch, baffle type, shell ID and tube length — or leave the geometry to us.

Materials & finish Shell-side, tube-side, tube and tube-sheet materials; radiography scope; surface finish — or the fluids, and we will propose them.
