About this file
This is a technical specification document for ductile iron process pipe prepared by Herbert, Rowland & Grubic, Inc., applicable to the West Pump Station Replacement Project in Pennsylvania under the Northwestern Chester County Municipal Authority. The specification establishes requirements for ductile-iron pipe, malleable-iron, cast-iron fittings, and related accessories for the project's force main piping and sanitary sewer piping systems. The piping must comply with AWWA C115, C150, and C151 standards with a Thickness Class 53 rating and 250 psi pressure rating. Interior lining options include Protecto 401 or Tnemec Permashield 431, while buried service piping requires asphaltic coating at 0.04 inch thickness and exposed service piping follows painting specifications. Fittings must comply with AWWA C110 and C153 standards for ductile iron, with groove joints conforming to AWWA C606 and mechanical joints following AWWA C111. Gaskets must be suitable for sewage applications, specifically American Turoseal Flange Gaskets with no substitutions permitted, and bolts and nuts must be 316 stainless steel.
Installation requirements mandate compliance with ASME B31.3 for exposed service piping and Section 33 31 23 specifications for buried service piping, with all piping run straight along alignment with minimum joints. Field work includes surface preparation through commercial sand blasting to SSPC SP 6 standards, progressive bolt tightening using torque wrenches, proper slope installation for venting and draining, and support installation per Section 40 05 07. Manufacturers must have minimum three years of documented experience, submit certificates of compliance, and provide shop inspection and testing results. Quality control requires post-installation inspection for coating or lining damage, pressure testing as specified in Section 33 05 05.31, laying tolerances of 1/4 inch in 10 feet, and cleaning of pipe interior throughout installation and after completion.
