Manufacturers of U Tube Bundle Heat Exchanger in Tirur

The U-tube head (U) is a very simple design requiring a bundle of U tubes, only one tube sheet, no expansion joints, and no rear-end head at all, allowing easy removal of the bundle. The thermal stress problem is eliminated because each tube is free to expand/contract independently. One disadvantage is, individual tube replacement is not possible except in the outer rows, and an even number of tube passes is required. Some tubes are lost in the center due to HEAT EXCHANGERS tube bend limit, and tube side mechanical cleaning of the bends is difficult. Flow-induced vibration could be a problem for tubes in the outermost row. It is the lowest-cost design because there is no need for the second tube sheet.

We also undertake the complete manufacture & supply of Tube Bundles / Tube Nests / U Tube Bundles only for existing heat exchangers.

Inter – Fitment is a major & critical point to be taken care off during the manufacture of the same, as the Tube Bundle is to be manufactured considering the tolerance of the existing heat Exchangers & not Code Tolerance.

For the same we either 1) Manufacture the Tube Bundle on manufacturer provided As Built Drawing or 2) Depute out Representative to the site for taking the actual dimension of the existing Tube Bundle and the Shell within which the same is fitting. Inter-Fitment guarantee is given by us.

We also undertake the complete manufacture of U Tube Bundles. For the same we have complete Set of Fixtures for the 3/2″ & 1″ OD Tubes. The minimum Bending Radius carried out by us so far is 1.5D. U Tubes manufactured by us meet the TEMA Acceptance Norms of 16 % thinning & 10 % Ovality.

Supply of Tube Bundles usually happen in cases of Oil Coolers, Inter-Coolers, After Coolers, U Tube Bundles, Strippers, Re-Boilers etc.

If Client gives us the Existing/Dummy Shell for the testing purpose then Existing/Dummy Shell is used or else Dummy Shell is fabricated for the same and supplied along with Tube Bundle after carrying out the testing.

U Tube Bundle Heat Exchangers can duplicate any existing bundle to include dimensions, materials and performance.

A heat-exchanger system consisting of a bundle of U tubes hairpin tubes surrounded by a shell. One fluid flows through the tubes, and the other fluid flows through the shell, around the tubes.

A U-Tube Heat Exchanger is the most common heat exchanger used in various industries with high pressure and high temperature.
