The following manual is available from the American Water Works Association

Ductile-Iron Pipe and Fittings (AWWA Manual M41) – This manual provides both technical and general information to aid in the design, specification, procurement, installation, and understanding of ductile iron pipe and fittings. It is intended for use by utilities and municipalities of all sizes, as well as, design engineers and consultants.

NAPF 100-02: Push Joint Pipe (ANSI/AWWA C111/A21.11)
A single rubber sealing type joint employs a circular rubber gasket. This push-on type joint is simple to assemble and fast to install. Eliminates the need for bolts, nuts and glands. The rubber gasket fits the inside contour of the bell which seats the gasket. The plain endo of pipe is slightly beveled to ease assembly.

Push Joint pipe is highly recommended wherever there is a need for an easily assembled tight joint for ductile iron pressure pipe. It is particularly well suited for water or other liquid service, providing an almost bottle tight environment.

100-03: Mechanical Joint Pipe (ANSI/AWWA C111/A21.11)

Mechanical joint is a time-saving, easily installed joint that insures long-term, trouble-free performance. Uncomplicated, this joint comprises a gland, gasket and bolts. It requires no mecanical skill to install, is unusully easy and fast to assemble. No special tools are required for installation other than a standard ratchet wrench. When properly installed, this joint will maintain a perfect seal indefinitely without further maintenance.

Mechanical joint is recommended for any gas, water or other fluid service, and where a virtually bottle-tight joint is a requirement. Parts are interchangeable with fitting accessories. Mechanical joint pipe is generally available thru 24" and fittings through 48".

The plain end of mechanical joint pipe has the same outside diameter as other push-on type joints. As a result, it can be fitted into such joints in the field merely by beveling the plain end pipe.

We manufacture and supply ductile iron pipe fabrications from 80mm-1200mm. We supply all sizes possible from short double spigots to longer double flanged pipes. All our pipework is available in BS EN545 blue and BS EN598 red.

1The use of the products and performanceNot only does ductile iron have high tensile strength and percentage elongation,but also have fine ductility and other excellent as anti-high-compression,

Anti-oxidation,anti-corrosion,etc.so the ductile iron pipe fittings are widely applied to such compressive pipes as water pipeline.oil pipeline,gas pipeline,sand pipeline,sewerage pipeline etc
