Drinking water delivery
MLC Uni Pipe & SAC Uni Pipe PLUS
Uponor Uni Pipe - the way forward for hygienic plumbing installations
Uponor UK offer two systems within its Uni Pipe range for safe and reliable drinking water installations:
- Multi-Layer Composite (MLC, Uni Pipe)- with over 3.8 billion metres of MLC sold since 1982, you can rest assured that this solution which combines the benefits of a metal and plastic pipe in one is the ideal choice for your next plumbing installation. The key features of this product include a 100% diffusion tight aluminium core for enhanced stability and a flexible polyethylene outer case.
- Seamless Aluminium Composite (SAC, Uni Pipe Plus)- developing the MLC range even further, Uponor's central innovation team in Germany have created the world's first composite pipe with a seamlessly extruded aluminium layer- SAC. This essentially ensures it is more flexible and bendable in tight installation situations in comparison to MLC. Other benefits include:
- Available as straight lengths and coils
- Reduced installation times
- Less components required, which reduces costs
- Uni Pipe Plus straight lengths feature a special aluminium layer that is more rigid than conventional MLC
- Provides a visually attractive, on-wall mounting solution
Pre-insulated MLC pipe is also available on request for special projects
