Coils:
Helical coils are frequently used for heating or cooling product in processing plant tanks and vessels. Tube coils provide an economical and straightforward method of obtaining heat transfer surface area. Tube coils are made by rolling lengths of tubing into helixes or double helixes in which the inlet and outlet are located side by side. Uneek Bending can supply various coils in various metals including titanium coils and duplex stainless coils, all of which can be supplied in segments or fully fabricated and hydrostatically tested.
Helical coils have a variety of different parameters:

Pitched or Closewound:
Pitched coils are wound at constant centre-to-centre pitch that is larger than the tube/pipe diameter. Larger or heavier pitched coils are normally provided with 3 or 4 supports. These supports are U-bolted to the tube. Closewound coils have a pitch equal to the tube/pipe diameter and are normally stitch welded together for rigidity.

Direction of Winding:
Direction is not normally important, but coils can be wound in either direction. the direction of winding is defined as clockwise or anti-clockwise up, when viewed from the top.

Single Start Coil / Multi Start Coil:
Most heating/cooling coils are single start but they can also be 2, 3, 4 or 5 start.

Coil sets:
Coils can be single helical, or they can be made in sets. With a double set, there is an inner coil and an outer coil. Normally, the inner coil is wound in the opposite direction to the outer coil so that the 2 coils can be connected at one end by a simple "crossover".

Ends:
There are many type of arrangements, but the most common are:

• 90°ends

• Ends are at top and bottom

• 2 x 90° ends at one end, with an internal riser

• Tangential ends

Flat Spiral Coils (Pancake)
Pancake coils are often used in heating applications where heat must only be applied at the lowest point of the vessel and thus a cylindrical coil is not optimal. Uneek Bending can produce these coils in a wide variety of sizes.

Suction Heater U-Tube Bundles
Uneek Bending can manufacture U-tube bundles to suit your needs.

Limpet Coils (Half Pipe Coils)
Limpet coils are half round heating/cooling tubes often welded to the walls of high pressure vessels. Uneek Bending manufactures large numbers of these coils for a variety of different industries.
