Standard Specification for Steel-Reinforced Polyethylene (SRPE) Corrugated Pipe

Abstract

This specification covers the requirements and methods of tests for steel-reinforced polyethylene (SRPE) corrugated pipe, couplings, and fittings for use in surface and subsurface drainage applications.

Nominal sizes of 300 to 1800 mm (12 to 72 in.) are included.

Materials, workmanship, dimensions, pipe stiffness, impact resistance, joining systems, and form of markings are specified.

SRPE corrugated pipe is intended for surface and subsurface drainage applications where soil provides support to its flexible walls.

Its major use is to collect or convey drainage water by open gravity flow as culverts, storm drains, etc.

Note 1—When SRPE corrugated pipe is to be used in locations where the ends may be exposed, above ground, consideration should be given to protection of the exposed portions due to combustibility of polyethylene and the effects of prolonged exposure to ultraviolet radiation, as well as corrosion of steel reinforcement.

This specification only deals with this pipe’s materials requirements.

The structural design of steel reinforced thermoplastic culverts and the proper installation procedures are given in the AASHTO LRFD Bridge Design Specifications, Section 12, and AASHTO LRFD Bridge Construction Specifications, Section 26, respectively.

Upon request of the specifying agency or engineer, the manufacturer shall provide profile wall section detail required for a full engineering evaluation.

The values stated in SI units are to be regarded as standard.

Within the text, the U.S. Customary units are shown in parentheses and may not be exact equivalents.

The following precautionary caveat pertains only to the test method portion, Section 9, of this specification: This standard does not purport to address all of the safety concerns, if any, associated with its use.

It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use
