Special Specifications

Other Considerations

PDH Questions

• Materials Procedure is in development

• Pipe Diameters of 30” and up

• Round Pipe, Oval Pipe, Boxes, Arches etc.

• Bypass pumping required

• Small construction

equipment footprint

1. Determine the exact dimensions and conditions

2. Thorough cleaning of host pipe.

3. Invert Repair (if needed)

4. Set up equipment, start spinning.

5. Special consideration for aluminum

6. Material Requirements:Vertical and Overhead Repair Material (701-08)

ASTM testing based on a pressure test

3” to 54” in diameter

Classifications by dimension ratio (DR=Do/t)

Special sizes available upon request*

Based on outside diameter

Do not bolt/anchor both ends of the liner

Cut the inlet flush with the headwall

Can use a “nose cone” for tight fits

Can place the grout tubes on the side of the liner, or inside the liner if needed.

Can usually handle a bit of scraping from the host pipe

ASTM Testing based on deflection of 3%

10” diameter up to 11 feet

Based on Inside diameter

Special sizes cannot be made

Classification by Ring Stiffness Coefficient (RSC)

Greater thickness (different wall structure) than solid wall

Cut/Grind and Rework the pipe over a tarp for easier clean up

Can be made into an “ovalized pipe” Ovalization should be secured by anchoring to a

headwall

Can bolt/anchor both ends

Do not leave the profile open

Rate is approximately 1” every 2 seconds

Depending on;

Temperature settings on the welding gun

Thickness of weld

Surrounding temperature

What are the three energy transfer medias allowed by NYSDOT for Cured In Place Pipe? (CIPP)

Hot Water

Steam

Ultra Violet

What Does CCCP stand for?

Centrifugally Cast Concrete Pipe

What are the two methods for Welding HDPE?

Butt Fusion Welding

Extrusion Welding

What are the two types of HDPE relining pipe? (NYSDOT Item # 706-11)

Profile Wall (ASTM F894)

Solid Wall (ASTM F714)

What are the most common mistakes made with specification 602?

Lack of complete scoping of project

Lack of adequate ROW

Remembering that excavation is NOT included in 602

Failure to understand the steps involved in the selected relining process.
