Based on pipes made in special technology, along with a broad range of fitting elements and accessories which make every type of connection possible, Tweetop PERT is a complete installation solution.

Tweetop PERT system offer includes pipes and fittings in 16 – 75mm diameters with a set of essential accessories and installation tools dedicated to specific applications of the system.

Tweetop PERT system based on multilayer pipes joined by pressed connections is currently one of the most advanced and innovative solutions available on the market. This is determined by two factors – the construction of the pipes and the connection technology. Tweetop PERT pipes have a multilayer structure – their core is made from an ultrasonically welded aluminium pipe. After adding two layers of the raised temperature polyethylene (PERT) material to the inside and outside of the aluminium pipe, we obtain a multilayer pipe capable of simultaneous work under the influence of pressure and temperature rated at 10 bar and 95°C. This unique combination of plastic material and the conventional aluminium insert allows Tweetop PERT pipes to keep the advantages of both, traditional and plastic pipes while eliminating their disadvantages.

Tweetop PERT system is ideal for both new investments and renovations of old installations in residential, public and historical buildings.

  • durability – elastic material structure is very resistant to constant impacts of pressure and temperature, system components can operate for minimum 50 years
  • energy-saving – due to low pressure losses and low thermal conductivity
  • hygienic – PERT plastics are non toxic ,neutral in relation to water and can be recycled
  • versality  – Tweetop PERT system is recommended for use in following types of installation:
    • cold/hot utility water
    • central heating (radiator connections)
    • surface heating
    • compressed air
    • ice water
    • technological and industrial
  • flexibility with no shape remembrance  – multilayer pipes are more flexible than any other known pipes and can be bended without any supports. Bending radius is on the level of 4-5 x Dn
  • thermal stability (0.025mm/mK) – very low thermal expansion coefficient (0.025mm/mK), is comparable with values characteristic for steel or copper pipes
  • resistance for oxygen diffusion – both pipes and fittings are totally resistant for oxygen diffusion
  • total impermeability of connections
  • possibility of making connection with any other pipe by using threaded couplings
  • high chemical resistance
  • low weight
