Twin Line Welding Tube, also known as Twin welding hose, is mainly used to transport oxygen and acetylene in welding machine, architecture and lacquer factory. It consists of two hoses, red and green. The green one delivers oxygen, and the red one delivers acetylene. The twin-line hose design is used to distinguish between oxygen and acetylene, while delivering different gases to welding equipment for efficient and safe welding and cutting.
Advantages of Twin Line Welding Tube
- Firstly, Reduce procurement costs: the integration of two pipes reduces the amount of material used, which is more economical than buying two hoses separately.
- Secondly, Reduce maintenance frequency: wear-resistant outer layer and pressure-resistant structure reduce the failure rate, long-term use can reduce the replacement frequency and maintenance costs.
- Thirdly, Standard color matching (red-acetylene, blue/green-oxygen) can intuitively distinguish gas types and reduce the risk of operational errors.
- Fourthly, Combine the oxygen (blue/green) and acetylene (red) hoses into one pipe to avoid the problem of traditional two separate hoses being tangled, greatly reduce the time spent on pipeline sorting on site, and improve the convenience of moving and operating.
