Abstract:

This specification covers ductile iron gravity sewer pipe centrifugally cast with push-on joints. This also covers trench load design procedures for both cement-lined pipe and flexible-lined pipe. Maximum depths of cover tables are included for both types of linings. Each pipe shall be subjected to a hydrostatic test and maybe performed either before or after the outside coating and inside coating have been applied, but shall be performed before the application of cement-mortar lining or of a special lining. The standard acceptance tests and additional control tests shall also be performed.

Scope:

1.1 This specification covers 4 to 64-in. ductile iron gravity sewer pipe centrifugally cast with push-on joints. This specification may be used for pipe with other types of joints, as may be agreed upon at the time of purchase.

1.2 This specification covers trench load design procedures for both cement-lined pipe and flexible-lined pipe. Maximum depth of cover tables are included for both types of linings.

1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
