10 The Primus Line system Technology and benefits

11 Parts The Primus Line system consists of... a flexible high-pressure liner and patented end fittings 11

12 Composition of the Primus Liner Composition of the Primus Liner External Layer Abrasion-resistant PE Protection of the fabric during insertion Internal Layer DN 150 DN 500 Based on PE or TPU NSF/ANSI 61, KTW W 270, AS/NZS 4020:2005 Kevlar Seamless, woven aramid fabric Accommodates the operating pressure independently from host pipe Wall thickness of 6 mm Liner is not glued to host pipe (no steaming or curing processes) Installed with annulus space 12
