AMERICAN Ductile Iron Pipe continues to expand and improve its offerings, most recently with the addition of MT Push Pipe and GS Push Pipe for trenchless applications.

MT Push Pipe 4" through 24" AMERICAN’s new “bell-less” ductile iron pipe has now been used as a trenchless carrier pipe for both water and sewer and for gravity and pressure applications. Our new MT Push Pipe is a specially designed and manufactured push-on joint pipe that offers a uniform outside diameter for the entire length of the pipe. The uniform outside diameter of the MT Push Pipe allows it to be effectively used in micro-tunneling and pipe rehabilitation for gravity or pressure applications up to 350 psi. Standard joint lengths of up to 19.5 feet are available.

GS Push Pipe 4" through 16" AMERICAN’s new GS Push Pipe offers a simple yet innovative approach for direct jacking, trenchless pipeline replacement, and micro-tunneling installations of gravity service lines. GS Push Pipe is a “bell-less” ductile iron pipe with a uniform outside diameter across the gasketed joint. The joint provides an efficient transfer of jacking loads from one pipe section to the next while providing a positive seal for gravity or low head applications up to 100 feet (43 psi). Standard joint lengths of up to 19.5 feet are available.

AMERICAN Responds to AWWA Article on Leachability of Regulated Metals from Cement Linings

The March 1998 issue of Journal AWWA contained an article concerning contamination of Portland cement used in insitu linings of water piping as practiced by contractors for various water utilities throughout the United States. The article was not about factory-lined ductile iron pipe and fittings supplied by ductile iron pipe and fittings manufacturers, although, by inference, it might cause concern about our products also. However, for two specific reasons, customers using AMERICAN Ductile Iron pipe and fittings should have no concerns about contaminating their water because of AMERICAN products. Here are the reasons:

1.

The authors of the AWWA article have confirmed that contamination of Portland cement comes from the use of hazardous waste fuel to fire the kiln producing the cement. AMERICAN does not use Portland cement in cement linings for pipe or fittings produced in kilns that use hazardous waste fuel.

2.

All AMERICAN cement-lined pipe and fittings are certified by NSF to meet or exceed all requirements of ANSI/NSF 61. To maintain this certification, an NSF representative inspects our plant annually and chooses samples for testing. NSF subjects these samples to leaching tests to determine the presence of contamination by the regulated metals (discussed in the AWWA article) as well as other contaminants.

To reiterate, there is no need for contamination concerns with the use of AMERICAN products.
