What we manufacture
Process equipment across the thermal and pressure envelope
Every unit is thermally rated, mechanically designed and detailed in-house, then fabricated under a documented weld and inspection plan. Tell us the duty and we will work back to the geometry.
Shell & Tube Heat Exchangers
Fixed tubesheet, U-tube, floating head and hairpin units for liquid, gas and steam duties — thermally rated to your process data sheet.
View shell & tube
Air-Cooled Heat Exchangers
Fin-fan coolers and condensers for sites where cooling water is scarce or expensive — the usual answer across Egypt and the Gulf.
View air-cooled
Pressure Vessels
Separators, receivers, accumulators, filters and knock-out drums designed to ASME VIII Div. 1 with full calculation and drawing packages.
View pressure vessels
Storage Tanks
Atmospheric and low-pressure tanks for water, fuel, chemicals and process intermediates — shop-built or field-erected.
View tanks
Mixers & Agitators
Top and side-entry agitators with impeller selection matched to the duty — blending, suspension, dispersion or heat transfer.
View mixers
Reactors
Jacketed and limpet-coil reactors with integrated agitation, heating and cooling — sized for the batch, not the catalogue.

One team from thermal design to hydrotest
Most equipment problems start on paper. Because our design office and our shop sit together, the drawing that goes to the floor is the drawing that can actually be welded, inspected and cleaned in service.
01
Thermal & process design
Duty, LMTD, fouling allowance and pressure drop worked from your data sheet to fix surface area, tube count and passes.
02
Mechanical design
Shell and head thickness, nozzle reinforcement, flange rating, tubesheet and support calculations to the governing code.
03
Fabrication
Rolling, forming, machining and welding to qualified WPS/PQR, with material traceability held against the mill certificates.
04
Test & documentation
NDT, hydrostatic or pneumatic test and a bound dossier: drawings, calculations, weld map, heat numbers and test records.

Materials
The right alloy for the service, not the easiest one to buy
Corrosion, chloride content, temperature and cleanability all pull the material choice in different directions. We will tell you plainly when carbon steel is enough and when it is not.
- Carbon steel — SA-516 Gr. 70, SA-106, SA-105 for general pressure duty
- Stainless steel — 304/304L, 316/316L, 321 for corrosive and sanitary service
- Duplex — 2205 and 2507 where chlorides defeat austenitics
- Copper alloys — admiralty brass, 90/10 and 70/30 cupronickel for seawater
- Titanium Gr. 2 — brine, bleach and aggressive cooling water
- Nickel alloys — Inconel and Incoloy grades for high-temperature duty

We model and animate our own designs, so you can walk through a bundle, a nozzle layout or a jacket arrangement at review stage instead of on the shop floor. These are our own units, from our YouTube channel.

Common questions
What buyers ask us first
Shell and tube heat exchangers, air-cooled (fin-fan) heat exchangers, pressure vessels, atmospheric and low-pressure storage tanks, mixers and agitators, jacketed reactors, and custom fabrication such as process skids and pipe spools. Thermal and mechanical design are done in-house, so we can start from a duty rather than needing a finished drawing.
We design and fabricate to the rules of ASME BPVC Section VIII Division 1, and you receive the calculations, material certificates, weld records, NDT reports and test certificates that evidence it. That is not the same as applying a certified U-Stamp, which additionally requires the manufacturer to hold a current ASME Certificate of Authorization and to have the work witnessed by an Authorised Inspector. Tell us at enquiry stage which your project requires and we will confirm the route in writing before you order.
Either. If you have complete drawings and a specification we quote and build exactly to them, and tell you before cutting plate if we spot something that will not pass a code check or cannot be welded as drawn. If you only have a duty, a footprint and a code, we do the process and mechanical design, issue drawings for your approval, then fabricate.
For a heat exchanger: the fluid and flow rate on each side, inlet and outlet temperatures, design pressure and temperature, and any allowable pressure drop. For a vessel, tank or reactor: volume, design pressure and temperature, the fluid, and any footprint or height limit. For a mixer: vessel dimensions, batch volume, viscosity, solids loading and what the mixing has to achieve. Partial information is fine — we will come back with specific questions.
Yes. If the shell is sound, retubing usually costs a fraction of a new unit and takes less time. We survey the exchanger, measure it ourselves and quote against what is actually there rather than an out-of-date nameplate. We also re-machine tubesheets, plug individual tubes during a turnaround, repair flange faces, and re-rate a unit whose process duty has changed.
Yes. We are based in Egypt and supply across the Middle East and North Africa, including Saudi Arabia, the UAE, Kuwait, Qatar, Oman, Bahrain, Jordan, Iraq, Libya, Sudan, Tunisia, Algeria and Morocco. Export documentation and packing for sea or road freight are arranged on request.
Request a quote
Send us the duty. We will send back a real proposal.
The more of the process side you can give us, the tighter the quote. If you only have a rough idea, that is fine too — start the conversation and we will help you pin the data down.
- Flow rates, inlet and outlet temperatures, and the fluids on both sides
- Design pressure and temperature, plus the governing code
- Any material, nozzle orientation or footprint constraints
- Data sheets, P&IDs or drawings if you already have them
