United Engineering Industries

Manufacturers of heat transfer equipments serving Oil & Gas, Power Generation Plants, HT/ LT Motors. We have wide range of Shell & Tube Heat Exchangers, Pressure Vessels, storage tanks as per as per the TEMA, ASME, API and IS standards.

United has completed projects in short period for supply of spares, re-tubing & maintenance of Oil Coolers & tube bundles for heat exchangers, LP Heaters already installed in commissioned plants.

We also have range of Finned Tubes an in- house facility. Currently, two ranges of finned tubes are under production. Finned tubes enable quicker dissipation and higher heat-Transfer coefficient is obtained in heat exchangers.

Crimped Fin: Spiral crimped Fin tubes are made under high mechanical tension bonding process; fin material is helically wound over the tube to get maximum contact of tube.
Maximum operating temperature for this fin type is 250°C.
Fin Material: Copper

Wire Wound:
These finned tubes have fins made of wire instead of strips. Continuous loops of wire are formed and are continuously soldered to the circumference of the tube to ensure 100% contact. Loops per turn and turns per foot can be altered as per surface area requirements. Due to continuous soldering of wire loops these finned tubes offer very high heat transfer efficiency with less air pressure drop.
Maximum operating temperature for this fin type is 180°C.
Wire Material: Copper: Bare & Tinned

We are now not only limited to heavy fabrication & heavy machining services but we are pioneers in supplies of Heat Exchangers & Industrial Coolers, End Shields, Fan Cover, Fan and other accessories of HT/ LT Motors.
United is a key supplier for all type of components of Motors for all OEM’s. Our manufactured Motor Bodies are used for various applications like energy efficient Motors, Air Cooled, Water Cooled Tube Ventilate Motors, Flame Proof Motor Body for Hazardous Area & Barrel Type Motor Body.

In this era of competition, Saving & Time is of the critical parameters and our supply scheme will fetch and benefit you in both ways. We are proud and glad to convey this supply scheme is one of its kinds globally, designed developed by United, Bhopal. The scheme has been adopted, appreciated and acknowledged by major motor manufacturers globally.
The key advantage of the scheme is:

Avoid assembly shop related issues esp. hole mismatch, improper fitting.- As it has been observed that many a times heat exchangers, end shield are being brought to our factory, match marking is being done at our works with the frame. Kit supply will eliminate the cost involved in moving the material and also save time.
One stop inspection point.
Minimize inventory.
Minimize follow-ups for different spares and avoid internal purchase orders for a project.
Save overall project execution time and faster delivery.

Phase segregated terminal boxes to eliminate phase to phase faults. In the event of a fault developing between phase and earth in one of the glass reinforced plastic terminal enclosure, the rapid buildup of pressure will cause the enclosure to fracture across the rear wall, thus releasing hot gases and flame into the steel phase segregated compartment.
If the fault level is low, fault products will be contained within the compartment.
If the fault level is high & excessive, then the Bakelite relief disc will fail and the fault product will pass into the motor interior where it will rapidly cool and disperse by venting into the machine space phase to phase fault are thus eliminated.
