HANCOR SURE-LOK
F477 PIPE SPECIFICATION
Scope
This specification describes 4" - 60" (100 - 1500mm)
Sure-Lok pipe for use in nonpressure drainage applications.
Pipe Requirements
Sure-Lok pipe shall have a smooth interior and annular exterior
corrugations.
- 4" - 10" (100 - 250mm) shall meet AASHTO M252, Type
S.
- 12" - 60" (300 - 1500mm) shall meet AASHTO M294, Type
S.
- Manning’s “n” value for use in design shall
be 0.010 to 0.012.
Joint Performance
Pipe shall be joined with the Sure-Lok (bell-and-spigot) joint
meeting AASHTO M252 or AASHTO M294. The joint shall be silt-tight
and non-rated watertight. Silt-tight joints shall meet laboratory test per ASTM D 3212 except that the joint be tested using 2.0 psi (14 kPa). Gaskets shall be made of polyisoprene
meeting the requirements of ASTM F477 with the addition that the
gaskets shall not have any visible cracking when tested according
to ASTM D1149 after 72-hour exposure in 50 PPHM ozone at 104°F
(40°C). Gaskets shall be installed by the pipe manufacturer
and covered with a removable wrap to ensure the gasket is free from
debris. A joint lubricant available from the manufacturer shall
be used on the gasket and bell during assembly.
Fittings
Fittings shall conform to AASHTO M252 or AASHTO M294.
Fabricated fittings, where accessible, shall be welded on the interior
and exterior at all junctions.
Material Properties
Virgin material for pipe and fitting production shall be high density polyethylene meeting
ASTM D3350 minimum cell classification 324420C for 4" - 10"
(100 - 250mm) diameters or 335400C for 12" - 60" (300
- 1500mm) diameters. The 12" - 60" (300 - 1500mm) virgin pipe
material shall be Hancor Resin 8™, which is a slow crack-resistant
material evaluated using the notched constant ligament-stress (NCLS) test. Average NCLS test specimens must exceed
24 hrs. with no test result less than 17 hrs.
Quality Assurance
Where requested, all corrugated polyethylene pipe meeting or exceeding AASHTO M294 shall only be provided by manufacturers listed by the Plastics Pipe Institute (PPI) as having met the requirements of the PPI sponsored third-party certification program. All AASHTO M294 pipe shall be clearly marked with a certification program mark or logo representing that the supplied pipe is in compliance with all applicable standards.
Installation
Installation shall be in accordance with ASTM D2321 and Hancor's published installation guidlines with the exception
that minimum cover in trafficked areas for 4" - 48" (100 - 1200mm) diameters shall be one foot (0.3m)
and for
54- and 60-inch (1350 and 1500mm) diameters shall be 1.5 ft (0.5m).
