FURTHER INFORMATION ON INSTALLATION & MORE

INSTALLATION • Introduction • Production • Installation • Advantages • Quality assurance • Summery and conclusion The close-fit-liner is inserted into the old pipe through existing manholes or small installation pits The liner is pulled into the existing pipe by a winch Re-deforming with steam and pressure Cooling down of the Sure. FIT® under pressure to ensure a close-fit position

THE MEMORY EFFECT • Introduction Above 80 °C the memory effect is activated … • Production • Installation • Advantages • Quality assurance • Summery and conclusion 2 h - 120 °C Round shape restored!

INSTALLATION • Introduction • Production • Installation • Advantages • Quality assurance • Summery and conclusion Installation lengths limited by the reel capacity which depends on the Sure. FIT® diameter and SDR DN 80 → > 1000 m DN 400 → ~ 111 m

JOINING TECHNOLOGY • Introduction • Production • Installation • Advantages • Quality assurance • Summery and conclusion Secure joining technology by welding Electro-socket welding Sure. FIT® has different measurements than standard pipes (e. g. : Sure. FIT ® DN 150 → standard pipe OD 160) Special welding procedure with expander required! Welding is only applicable when the round cross-section is fully restored!

JOINING TECHNOLOGY • Introduction • Production • Installation • Advantages • Quality assurance • Summery and conclusion Fittings: For most dimensions standard e-couplers are suitable. Some DN require special transition fittings.
