Heat Exchanger Manufacturer in Dubai

Shell and tube heat exchangers for the UAE’s process industries

Ultraweld Coat is a trusted Heat Exchanger Manufacturer in Dubai, UAE, designing and fabricating shell and tube heat exchangers for refineries, gas plants, petrochemical units and power stations. Each exchanger is built to the customer’s process data at our works in Pune, India and shipped to site in the UAE.

We manufacture in carbon steel, stainless steel, duplex stainless steel, titanium, Inconel and other corrosion-resistant alloys, so the materials can be matched to both the process fluid and the cooling medium.

Designing for Gulf operating conditions

Three local conditions shape most heat exchanger enquiries from the UAE.

• Seawater cooling: Gulf seawater is warm and highly saline, so the tube material on the cooling side has to resist chloride attack for the life of the unit.
• High ambient temperature: warm cooling water leaves a smaller temperature difference to work with, which means more heat transfer surface for the same duty.
• Fouling: scale and marine growth build up on tube surfaces, so designs need a fouling allowance and bundles that can be pulled and cleaned.

Frequently asked questions

How do heat exchangers work?

A heat exchanger passes heat from a hot fluid to a cooler one through a metal wall, usually the tube wall, without letting the two fluids mix.

Which tube material suits seawater cooling in the Gulf?

Titanium is widely used for seawater because it resists chloride corrosion very well. Duplex stainless steels are an alternative in some conditions. The final choice depends on water quality, temperature and budget.

Can heat exchangers be custom manufactured?

Yes. Every unit is designed around the customer’s requirements: size, materials, pressure rating, temperature and application.
