Overview
Product Overview
The Twin Welding Hose for Oxygen and Acetylene by Quanyi Rubber is a professional-grade dual-line composite hose engineered specifically for high-efficiency gas welding, flame cutting, and metal heating operations. Designed with a twin-bonded structure, it eliminates line tangling while allowing smooth mobility and easy color-coded gas identification (Red for Acetylene/Fuel Gas, Blue for Oxygen).
Manufactured from a high-purity rubber-plastic composite material, this hose incorporates specialized cold-resistant and flame-retardant additives. It effectively resists accidental sparks, molten slag contact, and high-temperature burns while maintaining flexibility without hardening in winter or softening in summer. The structural core is reinforced with double polyester yarn braiding, providing superior tension strength to handle dynamic pressure loads up to 30 Bar (3.0 MPa) and burst pressures up to 120 Bar (12.0 MPa).
Compared with traditional rubber hoses, our rubber-plastic composite formulation is 30% lighter, significantly reducing operator fatigue during long shifts while delivering superior weather, UV, and ozone aging resistance (maintaining a crack-free exterior for over 5 years outdoors). Fully compliant with national standards for gas welding equipment, it is the ideal flexible line for fabrication shops, construction yards, and industrial machinery maintenance.
