The difference between PEX and PERT pipe

Polyethylene (PE) pipes are popular choices for floor heating systems due to their durability, flexibility, and resistance to corrosion. Two types of PE pipes commonly used in floor heating systems are PE-RT and PE-X pipes. While both types of pipes have many similarities, there are some key differences to consider when choosing the right pipe for your floor heating project.
1.PE-RT (polyethylene of raised temperature resistance) pipes are known for their excellent heat resistance and are designed to withstand high temperatures and pressures. They are also highly flexible and can be easily installed in tight spaces, making them a popular choice for floor heating systems. PE-RT pipes are ideal for underfloor heating systems that require long continuous lengths of piping.
2.PE-X (cross-linked polyethylene) pipes are also designed to withstand high temperatures and pressures, but they are typically less flexible than PE-RT pipes. PE-X pipes are ideal for underfloor heating systems that require a lot of bends and turns in the piping layout. They are also a popular choice for installations that require pipes to be run through walls or ceilings.
3.(1)One of the key differences between PE-RT and PE-X pipes is their method of cross-linking. PE-RT pipes are cross-linked by adding chemicals to the polymer during the manufacturing process, while PE-X pipes are cross-linked using high-energy radiation or a chemical process. This difference in cross-linking methods can impact the durability and flexibility of the pipes.
(2)Another difference to consider is the cost of each type of pipe. PE-RT pipes are typically more expensive than PE-X pipes due to their higher heat resistance and flexibility.

4.In summary, both PE-RT and PE-X pipes are great options for floor heating systems. PE-RT pipes are ideal for long, continuous runs of piping, while PE-X pipes are better for installations that require a lot of bends and turns. Consider the specific needs of your project and consult with a professional to determine which type of PE pipe is right for you.
