Question 1

What is a barrier pipe used for?

Accepted Answer

Barrier pipes are used for plumbing and heating systems to prevent the contamination of drinking water with chemicals and gasses from the surrounding environment. The barrier layer in the pipe prevents the diffusion of these harmful substances into the water supply.

Question 2

What is the difference between barrier pipe and MDPE?

Accepted Answer

The main difference between barrier pipe and MDPE (medium-density polyethylene) is that barrier pipe has an extra layer of protection to prevent the permeation of gasses and other substances through the pipe walls. This makes barrier pipe ideal for use in gas and oil pipelines, while MDPE is typically used for water supply and drainage systems.

Question 3

What diameter is the barrier pipe?

Accepted Answer

Barrier pipe comes in various diameters, typically ranging from 15mm to 63mm. The specific diameter you need will depend on the application and requirements of your plumbing system.

Question 4

Does barrier pipe need insulation?

Accepted Answer

It depends on the specific application and local building codes. In general, a barrier pipe is designed to prevent oxygen from entering the system and causing corrosion, but it may still need insulation to prevent heat loss and maintain proper temperature. Consult with a professional plumber or building inspector to determine if insulation is necessary for your barrier pipe installation.

Question 5

Can you use compression fittings on the barrier pipe?

Accepted Answer

Yes, you can use compression fittings on barrier pipes, but it is important to use the correct type of fitting. Barrier pipe has an outer layer that prevents oxygen from entering the pipe and causing corrosion, so it requires fittings that are specifically designed for use with barrier pipe. Make sure to check the manufacturer's instructions and use the appropriate fittings for your specific type of barrier pipe.
