2019-04-13
The spiral protective sleeve is manufactured from PP, PE, or PA using a hot‑state winding and extrusion‑shaping process. It is a new type of product designed to replace traditional metal spring guards used for protecting hoses. Alternative names include spiral protective sleeve, hose protector, and oil‑pipe protector. This production line is dedicated to manufacturing spirally reinforced flexible hoses and comprises two extruders, a forming machine, and a cooling water tank. The hose wall features both soft and hard material spirals that enhance its pressure resistance. The resulting hose exhibits excellent properties such as crush resistance, corrosion resistance, negative‑pressure resistance, bend resistance, and superior flow characteristics. It is suitable for conveying gases, liquids, and granular materials, and finds applications in industries, agriculture, construction, and irrigation systems.

Purpose
This production line is dedicated to manufacturing helically reinforced flexible hoses and comprises two extruders, a forming machine, and a cooling tank. The hose wall features both soft and rigid helical reinforcements to enhance pressure resistance. It exhibits excellent resistance to compression, corrosion, negative pressure, and bending, while ensuring smooth flow. This hose is suitable for conveying gases, liquids, and granular materials, and finds applications in industries such as manufacturing, agriculture, construction, and water‑conservation irrigation.
Spiral protective sleeve
Spiral protective sleeves are rubber‑tube protection products manufactured from polypropylene or nylon materials through specialized processing techniques. The products typically feature a spiral shape and are also referred to as spiral rubber tube protectors.
Spiral sleeves are suitable for hydraulic hoses, providing protection for the internal components. They not only enhance aesthetics and improve restraint but also extend the service life of the internal components by more than three years.
PE carbon‑reinforced spiral‑wound pipes have seen rapid development in recent years, offering excellent toughness and corrosion resistance. They can withstand long‑term exposure to acids and alkalis, resulting in a long service life.
* Controlled by a PIC or a temperature controller.
* High extrusion rate, low melt temperature.
* A dedicated screw design enables high efficiency and high output.
* The high-hardness, low-noise helical gear design delivers reliable performance and long service life.
