Hose products need to handle high temperatures and environmental stress to prevent immature hose failure and security risks. Thermoplastic hose offers a wide diversity of added value over their rubber counterparts. Because a thermoplastic hose built with a high level of contact power between the layers of core, pigtail and coat. This contact generated because thermoplastic materials can re-melted during the manufacturing process allowing for both a chemical and mechanical bond.
A thermoplastic hose process that makes the difference
Polyhose’s unique bonding process creates projections on the outside of the core. That boost up into the braid while the coating material forced down into the braid from the outside. Each hose has specific effective characteristics, such as increased scratch resistance or consistent long lengths to decrease leak points. These hoses simply handle the high temperatures and environmental stress break down rubber hoses. Causing immature hose failure, unexpected safety risks and downtime, as well as, lost credit clean up and on-site job repairs.
In the past, the majority of hoses made from rubber but today, a thermoplastic hose may outlive conventional rubber products for several reasons.
- Rubber hose can crack from the low-temperature atmosphere; therefore, it may not work well in freezers and cold weather.
- Thermoplastics are constructed to handle low temperatures.
- Rubber may fatigue from the consistent flexing motion capable in many applications.
- The thermoplastic hose can have a fibre brace bonded between the hose and the coat designed to handle constant flexing, even at higher pressures.
In addition, these hoses attempt good chemical/corrosion resistance and can form for easy routing or bonded together to create a single unit from multiple hoses.
Hose core tube
Thermoplastic hoses are designed with safety and cleanliness in mind. The erosion resistant core control long-term system cleanliness with axis free construction to ensure zero lubricant contamination. And with fibre reinforced thermoplastic hose, there’s small to no epidemic due cutting because they do not require a hose saw. While cleanliness built in thermoplastic core tubes, some Polyhose hoses also maintain non-conductivity, keeping the operator safe from electric shock.
Hoses are extremely vulnerable to external damage once the jacket has been compromised. The jacket of a hose has one main job. It must protect the structural representation of the organization and the braided reinforcement. If it is cracked it allows the braid to exposed to the environment, chemicals and abrasives that are harmful to its integrity. Unlike rubber, a thermoplastic jacket will not decorticate, which can lead to jacket failure and wire weakness.
Most thermoplastic hoses character a UV and ozone resistant cover which resists cracking and UV damage, thus extending the service life of the hose. Polyhose also produces speciality jackets, offering increased resistance to the elements and/or flexing, a variety of colours and lay lines can customize, enabling customers to colour-code their systems and provide specific information on the hose itself.
Long continuous lengths of hose
The manufacturing process of thermoplastic hose grant for long continuous lengths due to the material being “cured” on the line and a self-supporting core tube. Rubber hoses require a secondary curing process and an axis to hold the core tube dimensions. The Polyhose have made continuous lengths of 3200m in the past – important for offshore oil applications such as marine (umbilicals). For hose assembly places, the long lengths mean minor scrap, minimized leak points and fewer reel changeovers during production.
By installing one bonded hose aspect multiple hoses, companies lower material cost, reduce installation time and weight of finish assembly. Thermoplastic hoses remove the problem of tangling in multiple hose applications and eliminate the abrasion damage caused hoses rubbing. They also improve management of the hose and increase the overall strength, eliminating some of reasons hoses fail in field. A bonded hose particularly beneficial in lift truck, hydraulic crane and aerial lift applications. Polyhose Thermoplastic hoses consist of two identical hoses permanently joined for the entire length of the hose, offering a compact system for easy installation and smooth operation. Multi-Line hoses dwell of two to ten hoses in various combinations of sizes and types. Where needed, hoses can separate to permit for routing.
Thermoplastic hoses with specific reinforcement have shown to reduce noise on machines. This important to operator comfort and environmental noise pollution.
