I. Introduction
Sinomin rubber flexible hose is provided with multi-layer rubber and metal, non-metal reinforcement phase and formed through special technical composition. The wear-resistant layer is the innermost layer, selecting high-quality, and high wear-resistant rubber to be treated through nano material formulation, which may be resistant to abrasion due to medium and resistant to wear. Adoption of high-quality S/S is made for framework layer, making in into metallic bellow with specific inner diameter and with special structure. The framework features flexibility to maintain the characteristics of rubber flexible hose. Meanwhile, it may protect the flexible hose from sagging due to the destroying load and pressure. The reinforcement layer is formed, through composition of special steel curtain wire and high strength curtain fabric, to withstand fluid static pressure during operating. The bonding layers are bonded with the rubber as an integral. The heat preservation layer is provided with energy-saving heat-preservation material. The thickness may be designed depending on the customers' requirements. The outer protective layer is designed according to heat-preservation layer, as a protective case, of which is woven with S/S wire or the other super high molecular non-metallic material.
II. Features
1. Good Flexibility and Impact Resistance
The hose features good bending performance, high strength, rigidness, and impact resistance. It features low linear expansion coefficient and creepage resistance as similar as steel pipe, The internal lining material has the best impact resistance and absorption performance of plastic, of which flexibility can greatly provide reliability of transferring system.
2. High Wear Resistance
The wear resistance is higher than that of steel pipe, S/S pipe, and wear- resistant metallic spraying by 4-7 times. It is more ideal to transferring raw salty materials for such small sized slurry as power coal ash, water coal slurry, tailing ore etc., which may greatly prolong service life of hose and may enhance the transferring efficiency by 20% or so.
3. Wide range of applicable temperature: -50 - 95.
4. High tensile strength: The connecting points of the hose and hose fittings are provided with lifting rigs for hose distribution.
5. Scale-inhibiting and Energy-saving
Good lubrication and non-adhesive may uneasily result in scale. The flow resistance is very small due to corrosive and wear resistance as well as without scaling on the inner wall of hose. It features small friction coefficient. It may keep constant flow velocity and flow rate, of which inner wall diameter is designed to lower than that of steel pipe by 150%. Especially, it is suitable for transferring high-viscosity slurry mixture and easily scaling power materials.
6. Corrosion Resistant and Anti-aging
It is unnecessary to apply corrosion protection coating materials during construction of hose. It may be resistant to erosion due to many kinds of chemical medium except for several medium. Apply oxidization inhibitor and carbon black UV absorbent into the formulation of raw material to feature outstanding anti-aging performance and good weather resistant performance. It features strong weather resistant and anti-aging performance due to stability of properties.
7. Easy Installation
The hose has good flexibility, of which is only 1/6 of that of carbon steel or S/S. It is very easy to loading/unloading, transportation, installation and use. It may accommodate all kind of ground foundation. It may be directly bent to be laid, with easy and simple connection, which may greatly save the consumption of labor force and material in the process of installation.
