Pipe Rehabilitation (Lining Products)

• Mandals Inversion Lining (general pipe rehabilitation)

  

• Mandals Tube In (rehabilitation of drinking water mains)

  

Mandals Inversion Lining is used for renovation of leaking transfer pipes (drinking water, methane gas, sewer, chemicals or other). It consists of a strong, circular woven polyester weave covered by thermoplastic polymer. It is inserted into the host pipe by reversion through use of compressed air or water. An epoxy resin introduced prior to installation will fix the lining to the pipe wall. Alternatively, the liner could stay loose in the pipe by terminating it with end couplings. All materials used are of premium quality, giving an outstanding service life of at least 50 years.The main advantages of this pipe renovation system are

• Cost savings (no need to invest in new pipes or excavation of such)
• The liner flexibilty vs. diameter variations of the original pipe
• Easy to pass even sharp bends also in longer lengths
• Reduced “out of service time” of the pipe system
