Definitions
- the present invention relates to a method for treatment of mechanical and thermal protection pipes for sheathing bundles of cables, pipes metallic, rubber, and others.
- Knitting technology has been known since long time. This technology is used for manufacturing protective pipes, both mechanical and thermal, for sheathing cable harnesses, pipes and others.
- the raw material used to manufacture these protective pipes are various wires, such way that in each needle of the machine knitting a determined number of threads is put in place.
- the hose tends to curl at the ends of the pipe forming small circumferences.
- the hose When leaving the machine, the hose has no expandability of the diameter, i.e. the diameter does not increase, adjusting only to a shape that have the internal diameter of the pipe.
- the hose coming out of the machine, has a longitudinal expandability, the diameter of it can be reduced.
- WO-A-91/14034 relates to a pipe knitted fabric and its manufacturing process.
- a knitted hose made of monofilaments in elastic plastic material.
- the ends of these pipes tend to open which is resolved by forming a layer of a solid material adhering to the filaments of the hose reducing the tendency to open but allowing the rotation of the monofilaments between them so as to maintain the expansion characteristic of the pipe.
- the hose is introduced into a bath and afterwards it is heated preferably at 150 ° C.
- EP-A-0134864 also relates to a pipe knitted fabric and its manufacturing process.
- the problem to be solved was the difficulty that arises when placing the hose around the cables or analogues.
- This document also provides pipe heating treatment formed by multiple filament yarns.
- the document EP-A-327 085 also describes a treatment for heating such pipes.
- the process for the treatment of protection is such that during the heating stage, the protective pipes are also subjected to a longitudinal tension included between 0.1 kg. and. 5 kg for a period of time between 10 seconds and 45 minutes.
- Temperatures and weather will depend on material of the tube to be treated, which will be heated to a temperature between 130 ° C and 190 ° C.
- son to multiple filaments are incorporated into said pipe before the heating the protection hose.
- said wires are incorporated into said pipe. textured material before heating the protection.
- the pipe is impregnated with resin before heating it.
- This impregnation with resin is realized only when the pipe includes yarns of textured material, which have a high absorption, or multiple filament yarns, which also have absorption, although less important than that of the threads of a textured material.
- This impregnation further strengthens the stability dimensional and a higher degree of hardness and flexibility high can be given.
- the single filament yarns have a diameter of between 1.1 mm and 0.3 mm.
- the pipe is impregnated with silicone or acrylic resin.
- the son of a single filament are of a plastic material chosen between polyester, polyamide and polytetra-fluorethylene (PTFE), while the filament yarns and the yarns of a textured material are polyester or polyamide.
- PTFE polytetra-fluorethylene
- the pipe can be cut longitudinally after heating it. Thanks to application of the method of the invention, the pipe does not not deform, it can be applied to objects already mounted.
- the process is applied to said protective pipe of the invention for a period of time of five minutes, by heating the pipe to a temperature of 170 ° C and subjecting it to a tension of 2 kg. Once this time period completed, we get a pipe with a internal diameter of 20 mm, with the above characteristics cited.
- the process is applied to said protective pipe of the invention for a period of two minutes, by heating the pipe to a temperature of 150 ° C and subjecting it to a tension of 0.6 kg.
- this one impregnates with acrylic resin.
- the process is applied to said protective pipe of the invention for a period of two minutes, by heating the pipe to a temperature of 150 ° C and subjecting it to a tension of 2 kg.
- the process is applied to said protective pipe of the invention for a period of time of five minutes, by heating the pipe to a temperature of 300 ° C and subjecting it to a tension of 2 kg. Once this time period completed, we get a pipe with a internal diameter of 20 mm, with the above characteristics cited.
- the protective hose after the process indicated has been applied to it, can be cut longitudinally. Thanks to the application of the the invention the pipe does not deform and can be applied to already mounted objects.
