About PERT-EVOH PIPE

 

PERT, PERT-EVOH PIPE (Polyethylene terephthalate-ethylene vinyl alcohol copolymer pipe) is a type of multilayer pipe. It is used for water and gas supply applications.

 

The main advantage of PERT-EVOH pipe is that it is resistant to both chemical and mechanical degradation. This makes it an ideal choice for use in aggressive environments.

 

PERT-EVOH pipe is also flexible and has a high resistance to impact. This makes it easier to install than other types of pipe.

Application of PERT, PERT-EVOH PIPE

     

Pipes are used in cold and hot water supply system and floor heating systems. The PERT-EVOH-PIPE lamination process is a new technology that offers the potential for the production of high performance plastic pipes. The process involves   the use of an EVOH resin and a PERT (polyethylene terephthalate) resin in a co-extrusion process. The two resins are laminated together to form a pipe with an   inner  layer of PERT and an outer layer of EVOH.

 

The benefits of this new technology include:

 

1. Increased Strength and Durability – The laminated pipe has increased strength and durability due to the high performance properties of the EVOH resin.

2. Improved Chemical Resistance – The laminated pipe has improved chemical resistance due to the presence of the EVOH resin.

3. Reduced Pipe Thickness – The laminated pipe has a reduced thickness compared to traditional plastic pipes, which results in weight savings and lower manufacturing costs.

4. Enhanced Heat Resistance – The laminated pipe has enhanced heat resistance due to the presence of the EVOH resin.

Features of PERT-EVOH PIPE

▪ PERT pipe: Monolayer with PERT.

▪ PERT-EVOH three layer pipe: Outer EVOH(oxygen-barrier) layer, adhesive, inner PERT layer

▪ PERT-EVOH pipe has all the same advantages as the regular PERT pipe and with a few extra.

①Enhanced thermal resistance and mechanical strength

②Thermal conductivity is more cost effective than metal pipes, therefore, saves insulation material cost.

③Easy cutting and convenient installation.

④Wonderful oxygen resistance. The outer layer of EVOH prevents diffusion of oxygen.

Why PERT-EVOH PIPE is so popular?

PERT-EVOH pipes are made of two different materials: polyethylene terephthalate (PERT) and ethylene vinyl alcohol (EVOH). PERT is a strong, durable material that is often used to make pipes for hot water systems. EVOH is a food-grade plastic that is often used to line food storage containers.

The combination of these two materials makes PERT-EVOH pipes ideal for use in food and beverage applications. The PERT layer provides a barrier to oxygen and other gases, while the EVOH layer prevents bacteria from growing. This makes PERT-EVOH pipes ideal for transporting food and beverages.

 

Knowledge of PERT-EVOH PIPE

PERT-EVOH pipes are made of polyethylene terephthalate (PERT) and ethylene vinyl alcohol (EVOH). PERT is a semi-rigid polymer while EVOH is a waxy, slightly brittle plastic. The two materials are co-extruded to form a pipe with an inner layer of PERT and an outer layer of EVOH.

The PERT-EVOH pipe was developed to address the issue of oxygen permeability in water pipes. Oxygen permeation can cause corrosion of metal pipes and leaching of lead from lead pipes. PERT-EVOH pipes are not susceptible to these problems because the EVOH barrier prevents oxygen from diffusing into the water.

PERT-EVOH pipes have been used in Europe for over 20 years and are now being used in North America. The pipes are available in diameters from 16mm to 630mm.

Here are some tips on how to maintain your PERT-EVOH pipes:

Inspect the exterior of the pipe for cracks or damage. Cracks can allow water to enter the pipe and cause leaks. Damaged

PERT-EVOH pipes are a type of pipe that is often used in the construction industry. These pipes are made from a combination of polyethylene and ethylene vinyl alcohol, which gives them their unique properties.

PERT-EVOH pipes are known for being strong and durable, as well as being resistant to both chemical and physical damage. However, like all pipes, they will eventually need to be replaced or repaired.

There are a few things that you can do in order to extend the life of your PERT-EVOH pipes. First, you should make sure that they are installed properly. Second, you should regularly inspect the pipes for any signs of damage. Finally, you should clean the pipes on a regular basis to prevent build-up from occurring.
