Spiral Reinforced PVC Suction Hose is an industrial hose specially designed for suction conditions. Its core structure is a spiral plastic reinforcement layer embedded in the flexible PVC pipe wall, which has both flexibility and anti-collapse ability.
Feature and structure design
1. Multi-layer composite structure
Inner layer: food grade or industrial grade PVC, smooth surface to reduce flow resistance and prevent material adhesion.
Reinforcement layer: plastic is wound in a spiral form to provide radial support force and resist the collapse of the tube caused by negative pressure.
Outer layer: wear-resistant PVC coating, added ultraviolet and anti-aging agents to adapt to outdoor environment.
2. Key performance parameters
Temperature range: -10°C to +65°C, beyond the range is easy to lead to plastic deformation or brittle fracture. Small bending radius, good flexibility.
Core advantages of Spiral Reinforced PVC Suction Hose
Firstly, Anti-collapse and pressure resistance
The spiral reinforcement structure keeps the lumen open when suctioning viscous fluids (such as sludge and oil), which is better than ordinary PVC hose.
Secondly, Wide chemical compatibility
PVC , the substrate is resistant to acid, alkali, grease and most solvents (avoid contact with strong oxidants such as concentrated nitric acid and ketone solvents).
Thirdly, Lightweight, flexible and easy to operate
Compared with rubber hose, it reduces weight by 30%, and the manual pipe is efficient and suitable for frequent moving scenes (such as construction site, farmland).
Fourthly, Economy and durability
The cost is lower than rubber, and the anti-aging formula extends the outdoor service life (typical life of 3~5 years).
Typical application scenarios
Firstly, Environmental water treatment: sewage suction, sludge transfer, river dredging (corrosion-resistant outer layer + anti-clogging lining)
Secondly, Industrial conveying: transfer of acid and alkali liquid in chemical plant, oil suction, pneumatic conveying of granular materials (chemical resistant coating + anti-static design)
Thirdly, Agricultural irrigation: farmland drainage, manure suction, mobile sprinkler system (wear-resistant outer layer + uv protection)
Fourthly, Food and medicine: sanitary transmission of food slurry and pharmaceutical intermediates Construction site: foundation pit drainage, concrete pumping auxiliary suction
Spiral Reinforced PVC Suction Hose has become the main type of pipe in medium and low pressure suction scenes due to its lightweight, anti-collapse and cost advantages. Correct selection and standardized use can maximize its efficiency and prolong its life.
