For Plastic Gravity Sewer Pipe

TYPE OF PIPE

This specification covers polyvinyl chloride
(PVC) gravity sewer pipe and fittings manufactured in accordance with ASTM Standard D-3034 and intended for use in drainage of sanitary and industrial wastes, storm water, and similar liquids. The pipe shall be made by continuous extrusion of green unplasticized PVC plastic and marked HAWK, as well as other markings prescribed by the ASTM Standard.

MATERIAL

Both pipe and fittings shall be made of PVC plastic having a cell classification of 12454-B as prescribed in ASTM D-1784. It shall be highly resistant to hydrogen sulfide, sulfuric acid, gasoline, oil, and other chemicals commonly found in sewage and industrial waste. It shall have a smooth internal surface for minimum flow resistance. When properly bedded and back-filled it shall withstand normally encountered loads without rupturing or leaking at the joints. In normal atmospheres, the pipe shall have a self extinguishing flammability characteristic.

CHEMICAL RESISTANCE

The resistance of the pipe and fittings to chemical reagents shall be tested in accordance with ASTM D-543 "Test for Resistance of Plastics to Chemical Reagents" and changes, if any, in weight or tensile strength must not exceed the limits specified in Table 2, ASTM D-1784.        

FOR CEMENTED JOINTS

The solvent cement used in cemented joints shall meet the requirements of ASTM D-2564 "Standard Specification for Cement for Polyvinyl Chloride (PVC) Plastic Pipe and Fittings." It shall produce a watertight joint that will have sufficient strength within five minutes after assembly to permit normal installation handling and moving.

FITTINGS

All fittings shall be of the same material as the pipe and shall be consistent therewith in strength, dimensions and utility. Adapters shall be provided for transitions to other pipe products.

DIMENSIONS

Dimensions of pipe and fittings up to 15" in diameter shall conform to ASTM D-3034 for "Type PSM Polyvinyl Chloride (PVC) Sewer Pipe and Fittings". Nominal laying lengths shall be 13 feet. Other lengths are available on special order.

JOINTS

Pipe Joints are to be made either by the use of solvent cement or an integral bell with elastomeric gasket.

FOR GASKETED JOINTS

Gasketed joints shall be used where service conditions may subject the installation to expansion, contraction, angular displacement of deformation of the pipe. To facilitate the assembly of gasketed joints, each pipe bell end shall have an internal groove to hold the gasket in place while inserting the spigot end of a mating pipe or fitting. Spigot ends shall have a chamfer and smooth external surface so that they may be readily mated with bell ends without cutting or deforming (pinching) the gasket.

The pipe joint meets ASTM D-3212 for joints for drain and sewer pipes using flexible elastomeric seals, and the seals meet ASTM F-477 for elastomeric seals. All gaskets are factory installed and have a steel reinforcing ring (Locked-in).
