Definitions

  • the present invention relates to a mechanical and thermal protection tube for cable bundles, gas pipes and tubular substrates in general.
  • the objective of the present invention is to achieve a protection tube that can be easily applied and, at the same time, is tightly fastened to the element to be protected.
  • the protection tube of the present invention is formed by a plurality of strands twisted together, and is characterized by the fact that it comprises threads of polymeric material of high shrinkage through the application of heat, its shrinking capacity being equal to or greater than 10%
  • said polymeric material is polyester, polyamide, polypropylene or polyethylene.
  • Said high shrinkage threads may be multifilament and / or monofilament threads.
  • a tube with a diameter large enough can be obtained so that its placement is easy on the substrate to be protected and, in addition, once placed on it, heat is provided by any suitable means and, when shrinkage of the threads used for this purpose occurs, the entire tube reduces its diameter, being solidly adjusted to the substrate and avoiding sliding on it, although its shape is irregular or with curved areas.
  • a protection tube according to the present invention was manufactured with the following parameters:
  • Type of thread polyester monofilament (PES) of rectangular section 0.28 x 0.56 mm. Shrinkage of 17% in hot air at 16O 0 C for 30 minutes.
  • PET polyester monofilament
  • the tube obtained has the following characteristics: Weight: 10.4 gr / m.l.
  • Diameter at maximum expansion 16 mm.
  • Return diameter without shrinkage 10 mm.
  • Return diameter after shrinkage at 175 0 C for 1 minute 9 mm.
  • a protection tube according to the present invention was manufactured with the following parameters:
  • Threads per spool 32 spools of 1-wire monofilament, 32 spools of 2-wire multifilament.
  • Type of thread 32 spools with polyester monofilament (PES) with a diameter of 0.22 mm in circular section. Shrinkage of 17% in hot air at 16O 0 C for 30 minutes. 32 spools with polyester multifilament (PES) of 500 dtex. Shrinkage 15% in hot air at 18O 0 C for 15 minutes.
  • PET polyester monofilament
  • the tube obtained has the following characteristics: Weight: 22 gr / m.l.
  • Diameter at maximum expansion 50 mm.
  • - Return diameter without shrinkage 22 mm.
  • a protection tube according to the present invention was manufactured with the following parameters: Number of reels: 80 Threads per reel: 2 - Density: 17 stitches in 3 cm.
  • Type of thread polyester multifilament (PES) of 1,100 dtex. Shrinkage of 18% in hot air at 18O 0 C for 15 minutes. Shrinkage force at 18O 0 C for 15 minutes 400 cN.
  • the tube obtained has the following characteristics: Weight: 24 gr / ml
  • Diameter at maximum expansion 24 mm.
  • Return diameter without shrinkage 15 mm.
  • - Return diameter after shrinkage at 175 0 C for 1 minute 13 mm.
  • the protection tube of the present invention can be obtained by means of braiding techniques, knitted fabric by warp, knitted fabric by collection or openwork fabric.
  • the dimensions and shapes of the threads can be variable, such as monofilament of circular, oval, rectangular or other section, multifilament with straight or textured filaments, with or without twist, etc.
  • the percentage and arrangement of the high shrinkage threads in the tube can be variable within the fabric structure of the protection tube.
  • the dimensions of the protection tube in terms of diameters, shrinkage capacity, thickness and others may vary depending on its final application.
  • the heating and shrinking system of the tube can be any of those known and commonly used, such as hot air application, infrared radiation, thermal radiation, etc.
