Heat shrinkable tubing rigid ratio 3:1 to 6:1, from Ø2 to 620mm

One of the strengths of the rigid tubing heat shrinkable is the width of its dimensional range. It is available in small sizes from 2 mm for the protection of fittings or small cables, but also in very large diameters exceeding 600 mm, used to coat whole ducts, ducts or mechanical parts. This diversity makes rigid tubing an extremely versatile product, suitable for both spot repairs and heavy industrial applications.

• Medium wall (semi-rigid) : final thickness ~1–3 mm. This tubing retains some flexibility but already offers good mechanical rigidity. It is often coated with adhesive for sealing. It is used outdoors or underground (wire protection, hydraulic ducting) where significant stresses are present. This medium wall is also the most economical solution : with equivalent diameter, it costs less than tubing thin or thick.
• Heavy wall (very rigid) : maximum thickness (3 to 5 mm). The tubing form a real shielding : It is reserved for the most severe environments. It is resistant to major shocks, corrosion, chemicals and allows maximum sealing (e.g. immersion). After tightening, the tubing thick acts as a moulded shell around the object, providing ultimate mechanical protection.

Made of polyolethin crosslinked rigid tubing retracts under the action of heat and takes the form of the support. What distinguishes it from a tubing thin, it is the large rise in thickness to the tightened : the ratio between the initial diameter and the final diameter, the final thickness may exceed 4 mm, transforming the tubing in a moulded shell that marries and protects the room.

Heat-retractable ducts are naturally associated with electrical wiring, but in the case of rigid ducts, more than half of the applications concern other domains. We find them for example

• in the protection of hydraulic or pneumatic pipes. For example in the business sector Career / BTP : in a maintenance operation on a quarry hydraulic line, a heat shrinkable tubing large diameter (400 mm) was used to cover a corroded area. Once restrained from the flame, it formed a protective envelope that extended the life of the pipe pending complete replacement.
• in the naval boilerhouse to protect pipes from salt water. Imagine a beam of sensor cables on an offshore platform, constantly struck by waves and salty air. One tubing to heavy wall acts like an envelope Waterproof black around cables, corrosion and shock insulation, a bit like a boat hull on sea pipes.
• for coating metal parts exposed to corrosion. For example in the railway building sector : on a wagon or under the rails, sheaths to medium wall protect wiring from vibration and dust. This is the equivalent of a polyoleon "ball-shield vest"thin for electrical wires, ensuring sufficient rigidity while maintaining a certain adaptability to the forms of the support.
• in mechanics to secure sensitive areas against shock or abrasion. So in heavy industry : Weld or replace parts on industrial machines where steam and oil can leak. One rigid tubing Waterproof (with adhesive) serves as mechanical insulation : It glues around the cable and forms a waterproof seal, preventing contact with liquids.

This expanded field of use explains their presence in sectors such as rail, heavy automobile, energy or maritime.

The rigid tubing heat shrinkable is not just an electrical product. It has become a transversal industrial tool, used as much for energy as for mechanics, pipeline protection or sensitive networks. Its wide range of diameters and versatility of application make it an essential reference for all those looking for robust, durable and adaptable protection.

For nearly 20 years, ACLP has been offering a variety of sheaths to medium wall or thick, with or without adhesive. ACLP offers you specific features among these sheaths : These are the medium walls with mastic, working sleeves for repair, thick walls with a shrink ratio up to 6:1, or sheaths medium wall in reel to isolate copper or busbar bars. Different formats exist : these products are offered in length 0.5m, 0.75m, 1m, or 1.22m.We can also cut to measure.
