IPR Overview

Benefits of Trenchless Solutions – Cured In Place Pipe

Cured In Place Pipe (CIPP)▪ CIPP is the #1 trenchless technology

used in the US for rehabilitation of sewer pipelines

▪ Involves inserting a felt tube, saturated with a thermosetting polymer into the damaged pipe. Steam heat is used to expand and cure the tube creating a new, long-lasting liner inside the pipe.

▪ IPR installs more than 1.5 million LF annually

RS Technik by HammerHead Advanced CIPP Process:

▪ Water & Pressure Pipes▪ Repairs pipes from 6”- 36”▪ NSF/61 Approved for

drinking water▪ Olin epoxy;

environmentally safe & Styrene-free

IPR Products & Services

RS Technik by HammerHead Advanced CIPP Process:

▪ Over 20 years experience and 40 million feet installed▪ RS Lining Systems first introduced RS Technik by HammerHead®

technology to the Americas in 2005.▪ In 2011, RS BlueLine® product received NSF61 certification for

potable water and first installations took place in Canada and the USA.

▪ In 2016, HammerHead® Trenchless Equipment acquired RS Lining Systems expanding equipment, services and solution offerings for pipe repair and replacement.

Real Time Data Logging

• Data Logging

• Logged in short time intervals (typ. 10 secs)

• Stored on a USB flash drive and backed up on an SD Card

• Batch files are downloaded and imported into an Excel spreadsheet template for reporting

• Remote Communications

• Remote monitoring, programming and troubleshooting by factory technician or contractor’s personnel


CIPP Pressure Pipe Considerations• Pipe diameter and thickness

- Operating pressure

• Site access• Existing pipe condition and • alignment

- Cleaning requirements- Bends, offsets

• Project scope- Economies of scale

• Quantity and location of setups• Line depth

- Access pits


CIPP Pressure Pipe Considerations• Fittings

- End seals- Service connections- Bends, valves, FHs, etc

• Temporary water service- Above ground temporary pipeline

designed for the system capacity and distribution needs.

• Testing requirements- Hydrostatic testing

- ASTM F1216: 1.5 times operating pressure OR operating pressure plus 50 psi (whichever is less)

• Traffic control

Design Considerations▪ Application: potable water and sewer▪ Pipe Type: DI, CI, PCCP, AC, PVC and

more▪ Pipe Condition:

✓ Access: small pit (5’x5’) at valves, hydrants, bends

✓ Bends: up to 45 degrees✓ Up to 10° deflection✓ Installation lengths: by project,

average 300-500 feet



CIPP Standards and Certifications• ASTM F1216 - Rehabilitation of Existing

Pipelines and Conduits by the Inversion and Curing of a Resin-Impregnated Tube

• ASTM F2994 - Standard Practice for the Utilization of Mobile, Automated Cured-In-Place Pipe (CIPP) Impregnation Systems

• AWWA Manual of Water Supply Practices M28, “Rehabilitation of Water Mains”

• NSF/ANSI Standard 61 - Drinking Water System Components – Health Effects

RS Technik by HammerHead Design Criteria

RS Technik by HammerHead Rehab Process

• Setting temporary bypass and water supply

• Creating access points to host pipe to facilitate installation of liner, fittings and connections

• Pipe cleaning and inspection

• Verification of pipe and liner dimensions

• Liner impregnation process

• Installation of liner into host

pipe

• Post-lining inspection

• Pressure testing

• Post-lining cleaning and

disinfection

• Reconnection of services and

connections

• Surface restoration

Installation Methods

Air Inversion Water Inversion

Pressure Test/Post Lining Cleaning & Disinfection


Robotic Service Connection Reinstatement


Pipe Flanges: Pre-

fabricated flange pieces are

attached and secured to the

host pipe.

Liner Installation: The

liner(s) are installed and

cured. The liner is trimmed

back inside the flange

pieces.

Finishing – End Seals: The

flanged ends are re-coupled

in-line with a new short spool

piece of pipe.


Objectives for Pressure Pipe Rehab

• Stop water loss / leaks

• Structurally renew existing pipeline

• Improve hydraulic characteristics

• Extend service life of existing pipeline

• Improve water quality

RS Technik by HammerHead – Spartanburg, SC

Project Details:

• Heavy traffic area downtown

Spartanburg

• Railroad crossing splits ROW from

City and DOT

• Water main breaks within 12

months made rehab time critical

• Project must be completed by June

30

• 1800’ Class IV structural liner

• 10” diameter DIP

• By-pass and temp water required

for fire service & several

businesses

RS Technik by HammerHead – Spartanburg, SC

• Completed on-time and on budget!

– Took 5 installations longest 350 ft.

– Short runs due to DOT and Railroad

• Line was inverted following ASTM F1216

• Cured utilizing ASTM F2994 (~ 6 hours)

• 6 man crew

• Passed hydrostatic test with flying colors!

– No discernible leakage at hydrostatic pressure test:

– 150psi for 1+ hour

• No businesses shut down during project

• By-pass utilized storm sewers, hardly noticeable
