The difference between PERT pipe and PEX pipe.

PERT and PEX are two types of plastic pipes that have gained popularity in recent years due to their flexibility and durability. PERT stands for Polyethylene of Raised Temperature Resistance and is a type of flexible plastic pipe that can withstand high temperatures, making it ideal for use in underfloor heating systems. It is also commonly used for hot and cold water plumbing systems.

PEX stands for cross-linked polyethylene, which is a more rigid plastic pipe that is often used for water supply lines in residential and commercial buildings. PEX is known for its flexibility, making it easy to install in tight spaces and around corners.

Both PERT and PEX pipes are lightweight and resistant to corrosion and chemicals, making them ideal for use in a variety of applications. They are also affordable and offer a long lifespan, making them a popular choice for many homeowners and builders.

First, the material of the pipe is different:

1. The raw material of PERT pipe is heat-resistant polyethylene PE-RT, which is melted at high temperature and then extruded into a material. The raw material of the pipe is non-toxic, and there is no cross-linking during the intelligent manufacturing process.

2. PEX pipe is a general term for a series, including PE-Xa, PE-Xb, PE-Xc, etc. The production process requires polyethylene for silane crosslinking.

Second, the maintenance methods are different:

1. PERT can be repaired by hot melt connection, and the pressure resistance performance after repair is the same as the original pipeline.

2. The PEX series pipelines can only be repaired by external pipe clamps.

Third,the scope of use is different:

1. In addition to floor heating, PERT can also be used in edible fluid production lines such as drinking water and beverages.

2. But PEX pipe is not good, because it is a cross-linked pipe and has certain toxicity.

When it comes to choosing between PERT pipe and PEX pipe, there are a few things to consider. PERT pipe is known for its flexibility, durability, and resistance to high temperatures. It is a great option for hot water applications, but it can be difficult to install due to its stiffness. PEX pipe, on the other hand, is known for its ease of installation and low cost. It is suitable for both hot and cold water applications, but it may be less durable over time. 

In general, PERT pipe may be a better choice for high-temperature applications, while PEX pipe may be a better choice for low-cost and easy installation. It is important to carefully evaluate the specific needs of your project before making a final decision. Consulting with a professional plumber or contractor can also be helpful in choosing the right type of pipe for your project.
