It’s generally used for welding. The red hose is to transfer inflammable gases. For example, acetylene. While the blue or green hose is to deliver oxygen. While the usages include ship building, nuclear power, chemical, tunnel and aerospace.
Twin welding hose connect the oxygen hose and acetylene hose. This can effectively avoid the 2 hose tie with each other. While once the 2 hose tie with each other, the oxygen and acetylene may mix. Then it will cause serious accident, even fire and explosion. Thus the twin hose can make the welding work more safe.
Product Features
Aging resistant
Because of the special synthetic rubber, our hose has better aging resistance. Thus it can serve outdoor for over 5 years without any crack on the surface. But the normal hose will crack within 2 years.
Pressure resistant
The hose can work at 20 bar. While the burst can be 60 bar. These are greatly beyond the demand. Higher burst pressure can protect the hose from the damage caused by improper operation. However, the traditional rubber hose will burst once the pressure increases.
Flexible in any weather
Special formula offers the hose great weather resistance. Thus it will never soften in summer and harden in winter. Besides, it remains flexible in cold weather.
Light in weight and abrasion resistant
The material and structure can effectively reduce the wear during use. Besides, the hose is light in weight. While the weight is just 50% of steel wire hose. Thus the wear will be small.
Twin welding hose color guide
When purchase twin welding hose, you can see there are different colors. Then which one is for oxygen and which one is for acetylene? In fact, the acetylene hose is red. While the oxygen hose can be green or blue. Because acetylene is flammable, the hose should be striking. While red is bright enough for this purpose. In another hand, red is often used to show some danger.
Frequently Asked Questions
1. What are the common applications for twin welding hoses?
These hoses are widely used in various industries, including shipbuilding, nuclear power, chemical processing, tunnel construction, and the aerospace sector.
2. Why should I use a twin welding hose instead of separate hoses?
The twin design effectively prevents the two hoses from tying together. Keeping them separated prevents the mixing of oxygen and acetylene, which is crucial for safety and avoids fire or explosion accidents.
3. How long does the hose last under outdoor conditions?
Thanks to our special synthetic rubber, the hose has excellent aging resistance and can serve outdoors for over 5 years without surface cracking.
4. What is the pressure rating of the hose?
The hose operates at a working pressure of 20 bar, with a burst pressure of up to 60 bar, ensuring durability against high-pressure demands.
5. What do the different hose colors signify?
The red hose is specifically for flammable acetylene gas, chosen for its high visibility, while the green or blue hose is used for oxygen delivery.
