Since 2010, Riyang has been committed to the research, development, manufacturing and sales of butt fusion machine.

Riyang products line includes butt fusion machine, hdpe pipe fitting machine, electrofusion machine, plastic sheet welding, socket fusion machine, pipe welding tools etc.

Insist On Quality

Riyang fusion machine is known for its excellent of engineering, ease of use and the ability to survive in the toughest conditions. Over the years, we have been continuously improving the details and quality of the machine. Before delivery, each machine must pass the "CTBD" inspection process, and all products are designed and manufactured in accordance with international standards and directives (ISO). Many of the original machines are still running in the field.We often work with front-line operators to improve the best method for Riyang fusion machine to work on the job site and workshop under the premise of ensuring the safety of the operator.

After 15 years of hard work, Riyang fusion machine has been applied to more than 60 countries and regions in the fields of polyethylene pipe manufacturers, gas construction projects, irrigation projects, mining and civil installations etc.

How could we select the right equipment for our project?
How long should it take to make a fusion joint?
How much temperature on the heater surface needed to butt fuse the pipes?
Why the heater surface temperature is different from that shown on the digital temperature control?
How much material should be faced from the pipe end before melting?
What should we do after facing the pipe ends?

Riyang could offer a variety of pipe fusion machine size up to 3000mm O.D. And each machine has the model number that indicates the maximum pipe size it can fuse. For example, butt fusion machine V630 could fuse maximum pipe 630mm O.D., and from the specification chart, you could always find the minimum size it can fuse. If you have specific requirements for your projects, please consult with Riyang sales.

How could we calculate the soaking time?
How could we calculate the cooling time?
After welding, could we lay down the jointed pipes on the ground for cooling process?
What is the power needed for Riyang pipe fusion equipment?
If the pipes are not properly aligned, what should we do?
What is the “drag pressure”?
How could we measure the “drag pressure”?

The proper soaking time varies depending on the pipe material, pipe diameter and wall thickness. You could always find the soaking time from Riyang operation manual for polyethylene welding machine.
