Composite Spiral Sheath Production Line

Applications The composite spiral jacket extruder is a newly developed integrated dual-extruder system by Shuangda, capable of producing spiral jackets in two colors and customizable to fit complete production lines. This production line is designed for manufacturing spiral-reinforced flexible hoses, comprising two extruders, a forming machine, and a cooling water tank. The hose wall features both soft and hard material spirals that enhance pressure resistance. These hoses exhibit excellent properties such as crush resistance, corrosion resistance, negative-pressure tolerance, flexibility, and good fluid flow, making them suitable for transporting gases, liquids, and granular materials across industries including industrial, agricultural, construction, and irrigation sectors. Spiral Jacket A spiral jacket is an external protective sleeve made from PP or nylon materials through specialized processing techniques. Typically shaped in a spiral form, it is also referred to as a spiral rubber hose protector. Spiral jackets are commonly used to protect hydraulic hoses, providing both aesthetic appeal and secure restraint while extending the service life of the hose by more than three years. PE carbon‑reinforced spiral‑enhanced pipes have seen rapid development in recent years and are currently regarded as superior conduits for protecting power cables. Their material boasts excellent chemical stability, outstanding electrical insulation and voltage resistance, high toughness, and strong corrosion resistance, enabling them to withstand long-term exposure to acids and alkalis. As a result, these pipes offer extended service lifetimes. 1. Temperature control via PIC or temperature‑regulating instruments. 2. High extrusion output with low melt temperatures. 3. Screw design optimized for high efficiency and productivity. 4. Helical gear design delivering high hardness, low noise, enhanced performance, and prolonged service life. 5. Standard DC speed control; optional variable-frequency and electromagnetic speed controls available. 6. Extruders can be interchanged according to different materials being processed.

Spiral sleeve

Spiral protective sleeves are rubber tubing protection products manufactured from polypropylene (PP) or nylon materials through specialized processing techniques. These products typically feature a spiral shape and are also referred to as spiral rubber tubing protectors.

Spiral sleeves are suitable for hydraulic hoses, providing protection for the product. They not only enhance aesthetics and improve restraint but also extend the product’s service life by more than three years.

PE carbon‑reinforced spiral‑wound pipes have experienced rapid development in recent years and are currently among the best protective conduits for power cables. Their material boasts excellent chemical properties, offering superior insulation and high voltage resistance, as well as outstanding toughness and corrosion resistance, enabling them to withstand long‑term exposure to acids and alkalis. Consequently, these pipes enjoy a long service life.
