requirements of this Section.
2.2 PIPEAND FITTINGS
A. Dimensions
1. The nominal inside diameter of the pipe shall be true to the specified pipe
size in accordance with ASTM D2513. Standard laying lengths shall be 40
feet + 2 inches.
2. Fittings such as couplings, wyes, tees, adaptors, etc. for use in laying pipe
shall have standard dimensions that conform to ASTM D2513.
3. Pipe and fittings shall have the Standard Dimension Ratio (SDR) rating
indicated on the Drawings.
B. Pipe and fittings shall be produced by the same manufacturer from identical
materials meeting the requirements of this Section. Special or custom fittings
may be exempted from this requirement.
C. Pipe and fittings shall be pressure rated to meet the service pressure
requirements specified. Whether molded or fabricated, fittings shall be fully
pressure rated to at least the same service pressure rating as the joining pipe.
D. Molded fittings shall meet the requirements of ASTM D3261 and this
Specification. At the point of fusion, the outside diameter and minimum wall
thickness of fitting butt fusion outlets shall meet the diameter and wall
thickness specifications of the mating system pipe. Fitting markings shall
include a production code from which the location and date of manufacture
can be determined. Upon request, the manufacturer shall provide an
explanation of his production code.
E. Perforated pipe shall meet the same physical properties and requirements of
standard solid pipe. Hole spacing and orientation are presented on the
Drawing. Sections of perforated pipe shall be fused together with perforations
aligned between each section of pipe.
F. Marking
1. Each standard and random length of pipe and fitting in compliance with
this standard shall be clearly marked with the following information:
a. Manufacturer’s Name or Trademark;
