【Product Overview】

The large-diameter cloth and spiral steel wire suction and discharge rubber hose is a special dual-purpose rubber hose for large-flow suction and discharge in water conservancy projects, mine infrastructure and municipal flood control, specially developed for complex negative pressure suction and positive pressure discharge working conditions. Adopting multi-layer composite integrated high-temperature vulcanization process, the layers are tightly bonded without delamination, bulging, cracking or leakage during long-term water and mud transportation. The external metal spiral wire reinforcement effectively resists negative pressure suction, preventing the hose from collapsing and deforming during operation. The hose is flexible, fatigue resistant, acid and alkali corrosion resistant, weather and UV aging resistant, no cracking or hardening after long-term outdoor use. Complete standard flange specifications, supporting non-standard diameter, special length and color customization to match various water pumps and engineering equipment.

【Product Structure & Core Material Description】

The large-diameter rubber hose adopts a scientifically stable multi-layer composite structure for high-strength suction and discharge working conditions. The first thickened wear-resistant and corrosion-resistant inner rubber layer is made of high-quality natural synthetic rubber, anti-scour and anti-corrosion with smooth inner wall reducing transportation resistance; The second single or multi-layer cloth winding reinforcement layer improves basic pressure resistance and tensile strength; The third high-strength cord braided layer strengthens the skeleton structure against stretching and twisting; The fourth external metal spiral steel wire reinforcement layer is the core anti-negative pressure structure to prevent hose collapse; The fifth weather-resistant outer rubber layer resists sun exposure and aging to protect the internal structure. The overall structure is sturdy and durable, suitable for harsh engineering construction environments.

【Product Custom Length & Diameter Description】

The large-diameter rubber hose has high customization flexibility to meet different construction distance requirements. Length customization: hoses below φ25 can be produced in 100-meter whole length without joints to reduce leakage risks; specifications above φ32 can be customized to any length according to actual construction needs. Diameter customization: complete conventional specifications, conventional diameter up to 1000mm, super large diameter can be specially customized for super long-distance large-flow drainage and dredging projects.

【Core Product Performance Advantages】

1. Dual positive and negative pressure dual-use: cloth, cord and spiral steel wire triple reinforcement, no collapse under negative pressure and no deformation under positive pressure; 2. High pressure and explosion proof: small deformation under pressure, tensile and fatigue resistant, bursting pressure far higher than working pressure, no pipe bursting or leakage; 3. Wear and corrosion resistant: thickened inner rubber resists sediment wear and sewage acid-base corrosion; 4. Aging and weather resistant: outer rubber resists sun exposure and high and low temperature, no cracking after long-term outdoor use; 5. Flexible and easy installation: good bending performance, convenient laying on complex terrain, tight flange sealing; 6. Complete customizable specifications: super large diameter, long whole length and non-standard flanges available for all large-flow engineering.

【Wide Application Scope】

Widely used in multiple industries. Mining for water supply and drainage and tailings transportation; agriculture and water conservancy for farmland irrigation and river water diversion; construction engineering for construction and tunnel drainage; municipal environmental protection for flood control, river dredging and sewage sludge transportation, essential rubber hose for large-flow water delivery projects.
