Custom Spirals

 

Custom spirals can be made from any of our standard polyurethane tubing sizes and can be bonded to create multi-core spirals. (For more information on bonded hose & tubing see our Technibond ® page.) We can create complete assemblies with fittings, couplers and covers, plugs, and Free Angle swivel fittings. Specifically for air tool applications, ask about internal lube lines and external capillary lines.

There are 4 standard items necessary for us to know to be able to quote your custom requirements on spirals. Color does not effect price, but should be indicated at time of order. A "drawing" will be issued detailing all spiral dimensions and pricing for your approval.

.   ID and OD of the hose.
.   Either total length or working length needed.
.   Tail lengths.
.   Fitting requirements.

 

Some of the terms we will use when quoting you will be:

Total Length- This will be the total length of the tubing before spiraling.
Working Length- Also known as Service Length . Defined by how far the spiral will stretch. Working length in standard spirals is approximately 80% of the total length. In Strong spirals, working length is approximately 60% of the total length. We are able to quote spirals by working length if you know how far you need the spiral to stretch from point A to point B. We are also able to quote by the number of turns.
Tail Length- Tail length dimensions are included in both total and service length dimensions. If necessary, we can quote compressed coils and add tail lengths to arrive at your requirements.
Compressed Coil, Turns or "C" Dimension- All refer to the amount of tubing which is actually spiraled. Our maximum "C" dimension is 64".
Coil ID- Our coil ID is determined by the size of the tubing being spiraled. This ID is small enough to allow the spiral to retract and prevent it from sagging while still providing optimum air flow without flattening the tubing.
Coil OD- Determined by Coil ID and OD of the tubing to be spiraled.

ATP has standard tooling that is selected per each size of tubing which allows for a maximum working length. Custom spiraling can be done on various tooling sizes per your requirements allowing various Coil ID's and OD's.

Dimensions are calculated by a computer. Actual dimensions may vary slightly. If dimensions are critical for your application, please advise us at the time of quotation so we may calculate accordingly.

We will make every effort to ensure the specifications of the spiral you order is accurate before production begins. However, due to their very special nature, custom spiral orders cannot be cancelled once production begins, and are not eligible for return except in the event of an error on the part of ATP or HWE.
