Introduction
In industries where hygiene, durability, and odor neutrality are non-negotiable, odorless steel wire-reinforced hoses have emerged as a revolutionary solution. As a leading Chinese factory with advanced technical capabilities, QINGDAO RENATO PLASTIC CO., LTD specializes in manufacturing high-performance hoses that meet global standards. This article explores the unique properties of our odorless steel wire hoses, their diverse applications, and the technical specifications that set our products apart.
This is an odorless PVC steel wire discharge hose. The hose is transparent, with a built-in steel wire reinforcement structure and a diameter of 38 mm. It is suitable for scenes where materials need to be discharged, such as industrial drainage, agricultural irrigation drainage, etc. Its odorless characteristics ensure the cleanliness of the use environment.
Key Features of Odorless Steel Wire Reinforced Hoses
1. Odorless Design
Material Innovation: Our hoses use food-grade thermoplastic polyurethane (TPU) or FDA-compliant PVC for the inner tube. These materials undergo a proprietary stabilization process to eliminate plasticizer migration, the primary source of chemical odors.
Certified Safety: Compliant with FDA 21 CFR 177.2600, EU REACH, and RoHS standards, ensuring zero VOC emissions.
2. Superior Durability
Reinforcement: High-tensile 304/316L stainless steel wire spiral or braid provides crush resistance and maintains shape under pressure.
Temperature Resilience: Operates in extreme conditions (-40°C to +135°C standard; customizable up to +200°C).
Abrasion Resistance: Outer cover made of hybrid polymers with UV and ozone resistance for outdoor use.
3. Chemical Compatibility
Resists acids, alkalis, oils, and solvents (pH 2–12), making it ideal for aggressive industrial environments.
4. Flexibility and Ease of Use
Minimum bend radius of 5× the inner diameter (ID) prevents kinking, even in tight spaces.
Applications Across Industries
1. Food and Beverage
Steam Transfer: Safely conveys steam for sterilization without contaminating products.
CIP (Clean-in-Place) Systems: Resists high-pressure cleaning agents and maintains odor neutrality.
2. Pharmaceuticals
Sterile Fluid Handling: Used in purified water distribution and API (active pharmaceutical ingredient) transfer.
Bio-Reactor Connections: Meets USP Class VI standards for biocompatibility.
3. Automotive and Manufacturing
Paint Spray Systems: Ensures odor-free airflow in automated painting lines.
Coolant Transfer: Resists glycol-based fluids and extreme temperatures.
4. Environmental Technology
Wastewater Management: Transfers corrosive chemicals in treatment plants.
Semiconductor Manufacturing: Compatible with ultra-pure water systems.
