PVC twin welding pipe is one of the best-selling PVC hoses nowadays. The tube body is made of PVC raw material, which is lighter than rubber material and easier to carry and control. During production, if two pipelines are connected together, customers can separate them according to their needs. Blue and red are the most common colors for twin welding hoses. According to industry standards, blue generally represents pipelines transporting oxygen, while red represents pipelines transporting acetylene. The reason for making pipes of different colors is to facilitate users to better distinguish and prevent confusion in transporting gases.
Material Structure

Effectively resist external impacts and ensure the high quality of the hose.
Both the inner and outer layers are made of PVC raw materials, while the inner layer is made of corrosion-resistant and chemical resistant materials. And the outer layer is designed with UV protection. All of these enhance the aging resistance of the pipes and extend their service life.
The middle layer adopts a high-strength fiber multi-layer winding design, which not only increases the pressure resistance of the pipe, but also effectively improves the explosion-proof force.
Feature

High pressure resistance: It can withstand working pressure and has wear resistance characteristics, ensuring long-term reliability.
Temperature adaptability: Supports a working temperature range of -10 ℃ to 65 ℃, meeting the requirements of conventional industrial scenarios.
Lightweight design: Lightweight, easy to handle, operate, and construct, reducing labor costs. Diversified connection methods: Supports welding, threaded or flange connections, adapting to different device interface requirements.
Environmental safety: free of harmful substances, in compliance with environmental standards, non-toxic release during use.
Application Scenarios

The PVC twin welding pipe is widely used in welding machines, metal cutting equipment, construction and paint factories, suitable for gas transportation such as oxygen (O ₂), acetylene (C ₂ H ₂), etc.
