Products Description
Manufactured by composite processing with a built‑in high‑strength steel‑wire spiral support framework and outer modified plastic material, the Steel Wire Spiral Plastic Duct provides excellent flexibility for free bending and stretching to suit diverse complex pipeline layouts. Operable within an ambient temperature range of ‑30℃ to 85℃, it offers wear resistance, anti‑aging performance and corrosion resistance. It is mainly deployed in industrial scenarios such as ventilation, smoke exhaust, dust‑particle conveying and equipment air exhaust. Lightweight for convenient cutting and installation, some transparent models enable direct visual inspection of internal medium flow. It has reliable negative‑pressure resistance to prevent collapse and deformation during suction operations, alongside strong tensile strength. Telescopically foldable with a small footprint, it fits ventilation and dust‑removal applications for factory workshops and mechanical equipment.
Product Structure
Spiral Steel‑wire Framework
A continuously wound high‑strength steel‑wire structure, acting as the core supporting component that reinforces the pipe body against negative pressure and compressive deformation.
01
Inner Conveying Pipe Wall
A smooth, wear‑resistant high‑molecular‑material layer that comes into direct contact with conveyed media. It ensures smooth material passage without wall adhesion or residue buildup.
02
Intermediate Composite Layer
A transitional composite structure connecting the inner and outer layers. It improves inter‑layer bonding strength to prevent delamination and separation during long‑term service.
03
Outer Protective Pipe Wall
An anti‑aging, wear‑resistant outer material layer that shields against external abrasion, impact and mild corrosive damage.
04
Sealed Connection Ports
Matching connection structures at both ends of the hose, enabling fast, leak‑free sealed connection with on‑site equipment ports.
05
Process Technology
Steel‑wire Coating Process
The steel‑wire framework is fully and evenly encapsulated inside the pipe wall to avoid rusting from exposed steel wires and enhance overall bonding strength.
Integrated Extrusion Molding Process
Multi‑layer materials are co‑extruded and integrally molded. Tight, void‑free bonding between layers prevents delamination over long‑term service.
Inner‑wall Polishing Process
Special polishing treatment is applied to the inner wall for a smooth, burr‑free surface, minimizing wall adhesion and residue when conveying powder and granular materials.
Synchronized Cooling and Shaping Process
Multi‑stage synchronized cooling and shaping is implemented during production to achieve uniform pipe‑body roundness and avoid local collapse.
Application Scope
Industrial Dust Removal & Ventilation
Used as ventilation and dust‑suction pipelines for workshop dust‑removal equipment. It easily adapts to bending offset requirements during equipment movement.
Sanitation Suction Operations
Matched with sanitation sewage‑suction and dust‑suction equipment. It resists pipeline collapse and blockage when sucking sewage and particulate waste.
Powder Material Conveying
Used for pneumatic conveying of powder and granular materials inside factories. Its smooth inner wall prevents material residue and pipeline blockage.
Agricultural Irrigation Water Delivery
Suitable for field and garden irrigation scenarios. It resists cracking and damage under outdoor dragging conditions.
Company Case
Precautions
Do not operate beyond the product‑specified negative‑pressure limit, as this may cause deformation failure of the steel‑wire framework and lead to pipe‑body collapse and damage.
Do not directly convey strongly corrosive media; standard non‑customized versions will suffer rapid corrosion and subsequent leakage.
Avoid prolonged exposure to intense sunlight during long‑term idle storage. Otherwise, aging of the outer‑layer material will accelerate, resulting in premature cracking and embrittlement.
Keep away from exposed sharp burrs and rebar ends during service to prevent long‑line scratches and direct damage to the pipe body.
Do not operate outside the product‑adapted temperature range; otherwise, pipe‑wall material performance will degrade rapidly and cause softening and damage.
fAQ
Q: Will it collapse under high‑negative‑pressure working conditions?
A: When operated within the designed negative‑pressure range, the pipe body remains fully unobstructed with no collapse or deformation.
Q: Can Steel Wire Spiral Plastic Duct convey corrosive materials?
A: Standard versions are compatible with most mildly corrosive media. Upgraded anti‑corrosion customized versions are available for strongly corrosive scenarios.
Q: Does it age quickly under long‑term outdoor service?
A: Standard models deliver basic anti‑aging performance. Weather‑resistant upgraded customized versions extend service life for long‑term outdoor applications.
Q: Can worn Steel Wire Spiral Plastic Duct be repaired and reused?
A: Temporary repair is feasible for minor local damage. Direct replacement is recommended for severely worn hoses to avoid unexpected rupture during operation.
