About VIALLI GmbH

VIALLI GmbH is a manufacturer registered in Munich of piping systems for hot and cold water supply. The product range includes pipes, fittings, valves and protective caps made of PP-R, PP-RCT, PEX-a as well as composite pipes with fiberglass or aluminium layers according to DIN 8077 and DIN 8078. Production takes place in Germany with extrusion, including three-layer co-extrusion for composite pipes, as well as injection molding for fittings. Products are used in drinking and hot water supply, heating, solar and air conditioning technology, irrigation, and commercial and industrial construction. Services include consulting from product selection through to installation, as well as a tooling program with welding sockets, pipe peeling machines and electrofusion welding machines. The company distributes its products via a dealer network across Europe, parts of Asia and the Middle East.

Materials and Production Processes

PP-R

Polypropylene Random Copolymer

Base material for pipes and fittings in plumbing and heating systems with high corrosion and temperature resistance.

PP-RCT

Polypropylene Random Crystalline Temperature

High-temperature-stable piping material for industrial heating systems and hot water networks.

PPR-FG

PPR with fiberglass layer (three-layer co-extruded, DIN 8077/8078)

Composite pipe with a low expansion coefficient and increased stiffness, suitable for solar and heating systems.

PPR-A

PPR Stabi with aluminium layer (DIN 8077/8078)

Oxygen-tight composite pipe with an aluminium core for heating, solar and drinking water systems as well as high-pressure irrigation.

PPR-UV

PPR with UV coating

UV-resistant version for outdoor applications.

PEX-a

Cross-linked polyethylene (PEX-a)

Flexible, temperature- and pressure-resistant pipe material for hot/cold water systems and pipe-in-pipe applications.
