Advantages of PE-ST-PU-PE pipes and ST-PU-PE pipes:

• efficient thermal insulation – connections without thermal bridges (in case of the insulated joint)
• possibility of insulating a joint – complete insulation tightness
• no corrosion in the external casing pipe

Additional advantages of PE-ST-PU-PE pipes:

• high smoothness of the PE pipe internal surface resulting in lower resistance of flow
• high resistance to abrasion caused by liquids containing suspended solids
• high chemical resistance to the vast majority of substances present in transported media
• no encrustation – hydraulic parameters are constant in time
• no corrosion of the carrier pipe
• excellent thermal insulation – low thermal conductivity coefficient
• longer life in comparison to steel pipes
