PPR Fiberglass Composite Pipe

Multilayer pipes that consist of three layers – an external layer, an internal layer, and a middle layer made of polypropylene and fiberglass – are known as PPR Fiberglass pipes. These types of pipes are preferred for hot water applications due to their increased pressure durability and lower thermal enlargement.

Polypropylene pipes are a popular choice for water supply systems due to their low cost and long lifespan. Thanks to their non-corrosive structure and non-toxic substances, they are safe to use for both hot and cold water. Glass fiber composite pipes are also widely used in heating systems, as they have a low elongation coefficient and can withstand high temperatures. Glass fiber pipes offer an easier installation than foiled pipes, as they do not require additional processes such as cleaning or shaving

Key characteristics of PPR Fiberglass pipes:

• They are welded as normal PPR – exterior layers do not have to be removed prior to welding
• Increased range of working temperatures – shape retention in the range of 0-90°C
• More than 50 years of durability in 10bar and 70°C
• Increased stability (larger distances between bearings)
• Low thermal expansion (α= 0.05)
