Large Diameter Steam Rubber Hose

JIDONGDA Large Diameter Steam Rubber Hose is suitable for various harsh high-temperature steam conditions. Its inner layer uses heat-resistant synthetic rubber, combined with multiple layers of high-strength fiber/steel wire composite reinforcement, ensuring stable performance under high temperature, high pressure, and repeated thermal shock.

A full range of hose diameters are available to meet various flow requirements, making it a flexible alternative to rigid metal hoses in temporary connections, equipment cleaning, and pipeline bypass scenarios.

As a high-quality supplier rooted in China, JIDONGDA's factories have achieved a closed-loop production process from rubber compounding to finished product assembly, strictly controlling quality at each stage to ensure the safety and service life of industrial customers both domestically and internationally.

Performance Testing and Quality Control

1. High Temperature Resistance Test: Medium is saturated steam, applicable temperature 150℃~220℃; no softening, bubbling, or delamination after 72 hours of continuous operation

2. Pressure Resistance Test: Working pressure 0.6–1.6MPa, burst pressure ≥ 3 times working pressure; employs alternating water pressure and steam impact testing.

3. Pulse Fatigue Test: Simulates steam start-up and shutdown thermal shock, cycle count ≥ 20,000 times, pass standard: no delamination, no leakage.

4. Full Inspection Airtightness Test: All flange joints undergo 100% airtightness testing, factory standard: zero leakage under rated pressure.

Real Industrial Application Case

Case Study: Steam Sterilization Pipeline Retrofitting in a 2000-ton/day Food Processing Plant. A large dairy factory in Southeast Asia had existing rigid metal pipes used for steam sterilization in its production line, which presented problems such as limited flow, difficult disassembly and retrofitting, and high construction costs.

In 2024, the factory purchased a custom-made Large Diameter Steam Rubber Hose from JIDONGDA, with a working pressure of 1.0MPa, a temperature resistance of 180℃, and a multi-layer fiber-reinforced structure. The effects after one year of continuous use are as follows:

1. The large-diameter design increases steam delivery flow by 35%, shortens sterilization time, and increases daily production capacity;

2. Excellent flexibility reduces pipeline modification and construction time by 60% compared to metal pipes;

3. Quarterly inspections showed no leaks, no bulging of the inner rubber layer, and no aging or damage to the outer layer;

4. Overall pipeline maintenance costs are reduced by 28% annually.

The customer has made three consecutive repurchases and recommended this product to its partner paper mill, establishing a long-term and stable supply partnership.

FAQ

Q1: What is the difference between EPDM inner rubber and fluororubber inner rubber in large-diameter steam hoses?

A1: EPDM offers high cost-effectiveness and is suitable for steam below 200℃, widely used in the food, paper, and conventional chemical industries. Fluororubber can withstand ultra-high temperature saturated steam of 200–220℃ for extended periods, resisting trace amounts of chemical steam corrosion, making it the preferred choice for petrochemical and high-temperature power plants. Both materials have passed our factory's 72-hour high-temperature aging test standard.

Q2: Can this Large Diameter Steam Rubber Hose be installed outdoors year-round?

A2: Yes. The outer layer uses a special ozone- and UV-resistant rubber formula, resistant to sun, rain, and atmospheric aging. For long-term outdoor installation, we recommend the steel wire spiral reinforced version to improve compression resistance and extend service life.

Q3: How can we confirm the burst safety of a custom-made flanged large-diameter steam hose?

A3: All custom-made flanged hoses undergo burst testing (minimum 3 times working pressure) and all have completed airtightness testing. We can provide a complete set of test reports for high-temperature aging, pulse fatigue, and hydrostatic testing for project acceptance and safety archiving.
