1. Heat exchanger tubes in various copper alloys

Our product range comprises heat exchanger tubes as seamlessly drawn smooth tubes in various copper alloys in all relevant dimensions. High-precision surfaces and dimensions form the basis for the exceptional quality of our products. Our ability to supply tubes in fixed lengths eliminates the unnecessary waste entailed when customers must cut tubes to size.

  • Copper alloys impress with their excellent properties:
        – High heat conductivity,
        – Excellent corrosion resistance (even compared to stainless steel),
  • Specific alloys (special brass, aluminium-bronze, coppernickel) are adapted for ideal
        performance under various operating conditions.

Even copper alloys are still undergoing a process of continuous improvement to optimize their corrosion and erosion resistance.

Additional product characteristics:

a) Dimensional range:

  • diameter: 0.24 – 4.02 in. (6 – 102 mm)
  • wall thickness: 0.01 – 0.33 in. (0.3 – 9 mm)
  • length: up to 984 in. (25,000 mm)

b) Annealing conditions:

  • hard
  • annealed conforming to standards (soft, half-hard, blank, etc.)
  • according to customer specifications

c) Special forms:

MPG is one of the few suppliers in the world able to manufacture tubes up to a length of 984 inch. Condenser tubes can also be bent into a u-bended upon request.

2. Fin tubes type N and type M

Fin tubes start out as seamless or welded, cold drawn smooth tubes made of various materials (copper alloys, titanium, stainless steel, steel). Through a rolling process, the fins are created out of the tube’s walls – tube and fin are thus all of a piece.

This ensures optimal heat transfer. In these areas of application, tube types N and M
have proven their value for use in a number of processes:

  • Condensation,
  • Evaporation,
  • Cooling and heating of liquid and gaseous media such as water, oil, steam, air, coolants and others.

Fin tubes type N and M are also available in a bimetallic version.

3. Corrugated tubes

Corrugated tubes are made of thin-walled smooth tubes in various materials. Using a special manufacturing process, the outer and inner surfaces are embossed with spiral grooves all around. This results in increased heat transfer to the inner side of the tube – particularly in turbulent currents. Corrugated or cross-corrugated tubes also allow for better condensation run-off or for the targeted build-up of a liquid film on the outer side of the tube.

4. HCI high-performance fin tubes

MPG high-performance fin tubes, type HCI, are based on precision- made smooth tubes. The fins are formed without cutting, meaning that tube and fins are all one piece. The special structure of the outer and inner tube surfaces of MPG highperformance fin tubes affords optimal heat performance and the right properties for minimizing the use of materials and coolants. The three-dimensional moulded shape of the fins promotes better run-off of the condensate from the cooling surface. Interior structures minimize the depth of the laminar boundary layer and increase turbulence. The formation of the inner and outer surfaces is coordinated to provide a substantial increase in the tubes’ thermal performance.

5. Bimetallic tubes and safety tube-in-tube systems

Bimetallic tubes combine the positive properties of different materials for use in various media. When using materials that can be hazardous to human health or to the environment, safety always comes first. With our safety tube-in-tube systems, MPG offers added protection – through double walls and the possibility of monitoring leakage. Bimetallic tubes, in the form of fin tubes, are a safe and economical solution for heat transfer in aggressive media, since expensive, corrosion-resistant materials can be combined with less expensive ones.

7. Heat technology design and consulting

As energy resources become ever scarcer and thus more expensive, the rational conversion of energy using heat transfer takes on central economic importance. MPG products can contribute to optimizing heat transfer processes, thereby increasing efficiency. Take advantage of our wide-ranging knowledge in the optimization, design and construction of heat exchangers.
We can demonstrate the tangible efficiency benefits offered by our energy-generation products by measuring the performance of prototypes in our heat technology laboratory.
