Large-diameter helical steel‑wire‑reinforced rubber hoses are flexible conveying hoses with a rubber matrix and a multi‑layer fabric‑and‑helical steel‑wire carcass. They combine excellent pressure resistance, weatherability, and flexibility, and are specifically designed for high‑flow, medium‑to‑low‑pressure fluid‑transport applications.
Large-diameter helical steel‑wire‑reinforced rubber hose is a flexible conveying pipe that uses rubber as the matrix and multiple layers of fabric reinforcement combined with helical steel wire as its skeleton. It offers excellent pressure resistance, weatherability, and flexibility, and is specifically designed for high‑flow, medium‑to‑low‑pressure fluid‑transport applications.
Material: Oil-resistant, wear-resistant nitrile rubber (NBR) or acid- and alkali-resistant ethylene propylene diene monomer rubber (EPDM)
Function: Directly contacts the conveyed medium, providing sealing and chemical‑resistance properties to ensure the purity of the medium.
Reinforcement skeleton layer
Fabric layer: Composed of multiple layers of high-strength polyester canvas laminated together, providing basic tensile and swell resistance.
Helical steel wire layer: High-carbon galvanized steel wires are helically wound, forming the core pressure-bearing structure that resists both internal and external pressures, thereby preventing the pipe from collapsing under suction or overexpanding.
Function: The multi-layer composite structure significantly enhances the hose’s pressure resistance, deformation resistance, and impact resistance.
Outer rubber layer
Material: Wear-resistant, weather-resistant chloroprene rubber (CR) or polyurethane (PU)
Function: Resists ultraviolet radiation, ozone, mechanical abrasion, and chemical corrosion; adapts to demanding outdoor and marine environments; and extends the service life of hoses.
Product Usage
In the petrochemical sector: long-distance transportation of crude oil, refined petroleum products, and drilling mud; oil loading and unloading at port terminals; and bilge oil pumping from ship holds.
Municipal water conservancy projects: urban flood control and drainage, river channel dredging and sediment transport, and sludge discharge from wastewater treatment plants.
Mining and metallurgical industries: transportation of mine tailings slurry and smelting slag; pipeline transport of ore‑processing plant pulp and concentrate powder.
Agricultural irrigation sector: large-scale farmland drainage and irrigation, and wastewater discharge from livestock farms.
Marine Port Engineering: seawater conveyance in coastal areas, port dredging operations, and ballast water replenishment for vessels.
Industrial production scenarios: fly ash conveyance in power plants, cooling water circulation in steel mills, and discharge of acidic and alkaline waste liquids in chemical plants.
Core Technological Advantages
High‑flow conveyance: Pipe diameters can exceed 305 mm, meeting high‑flow transport requirements with efficiency significantly surpassing that of conventional steel pipes.
Excellent flexibility: It can accommodate installation on complex terrains, reducing the number of bends and joints, thereby lowering installation costs and the risk of leaks.
Excellent weather resistance: The outer rubber layer is aging-resistant and UV‑proof, enabling long-term stable operation in environments ranging from –40°C to 80°C.
Easy installation: Lightweight and highly flexible, it can be quickly connected and laid, making it ideal for emergency response and temporary conveyance applications.

Factory workshop
Jiuxing Rubber & Plastic is a 100% manufacturing enterprise specializing in hydraulic hoses and industrial hoses, covering all fields including oil and gas, agriculture, transportation, construction, mining and forestry.
Laboratory
Our factory has introduced a complete set of laboratory testing equipment. We possess advanced laboratory capabilities and can conduct product quality inspections and research and development work to ensure stable and excellent product quality.
After purchasing raw materials, we will test each batch to ensure it meets the technical requirements of our products.
After production is completed, we will test each hose, including its working pressure and burst pressure, and conduct pulse tests for each order to ensure 100% qualification of the factory-finished products.
We strive to provide customers with top-quality hoses and do everything possible to ensure their quality.
Product packaging and transportation
I. Order Confirmation
After the order is placed, the customer service and the business team will immediately verify the product specifications, quantity, delivery date, and special requirements. After production is completed, a full inspection will be conducted to ensure that the size, performance, and appearance meet the standards. Only after passing the inspection can it proceed to the packaging stage.
II. Professional Packaging
According to the customer's requirements, the hydraulic hoses will be packed in cardboard boxes or wooden boxes. After the hoses are produced, we will pack them. Usually, woven bags and plastic films are used for packaging. Special packaging can be provided according to the customer's requirements. Special packaging is the requirement of the Edible ACC Ording customers.
