"CULVERT RENEW"^® Specification

Large Diameter Closed Profile, Culvert/Sewer Pipe

I. THE PRODUCT: The pipe is a helical-spiral manufactured with a smooth internal and external surface, inside diameter sized, hollow-wall closed profile, HDPE pipe. Standard profile pipe shall exhibit a pipe stiffness of 46 psi when tested in accordance with ASTM D-2412, and in accordance with municipal and highway specifications including AASHTO design specification, section 18, paragraphs 18, 4.0, 18, 4.1, etc. Low profile pipe stiffness shall be in a manner to develop the tensile strangth of the pipe; and to manage thermally induced seasonal contraction. It is capable of being pushed (or jacked) into the host pipeline, and being pulled into the host pipeline without joint separation. The connection is the Thread-Loc^® connection which threads the helical spiral together forming an integral joint. The OD and ID joint surfaces are substantially flush with the pipe OD and ID.

II. THE MATERIAL: The material from which the pipe is extruded shall be high density polyethylene "pipe grade" material listed by the Plastic Pipe Institute (PPI) as a PE 3408 resin; and exhibiting the physical properties described within the polyethylene material standard, ASTM D-3350, with a cell classification of 345464C as follows:

The manufacturer shall provide certification that the pipe was manufactured from one specific resin in compliance with these specifications.

III. DIMENSIONS: Pipe sizes, inside diameter, and typical dimensions shall conform with those listed. The outside and inside diameter shall be hydraulically "smooth" and of consistent pipe dimension along the pipe length.

V. INSTALLATION: For slip lining or insertion renewal, the pipe shall be installed in compliance with the manufacturer's guidelines. Completion of the joint shall be effected by use of a strap wrench device with a suitable (4 foot minimum) bar or lever to tighten the pipe. The pipe shall be kept level with support slings, rollers or other devices as approved by the owner or engineer. Chemical grouting or mastic sealing of the joint shall be done to manufacturer's recommendations.

Direct burial, bedding, backfill, and general installation requirements should comply with the specifications and guidelines of ASTM D-2321.
