performance of SRPE pipe

[cvg]

anybody have any experience they can relate with the design, installation, cost or performance of steel reinforced polyethylene pipe (SRPE)?

Specifically:
[ul]
[li]n-value[/li]
[li]design method[/li]
[li]agency acceptance[/li]
[li]pipe bedding[/li]
[li]deflection criteria[/li]
[li]leakage[/li]
[li]long term performance[/li]
[li]comparison with RCP[/li]
[/ul]

Never heard of this pipe. Who makes it? The n value should be the same as HDPE unles the 'steel' protrudes into the inside of the pipe.

CVG,
I got a visit from the Contech guys a few months ago and provided me with information on this pipe material . I thought they said that this was relatively new to the US. You may want to contact them to get contact information from places(DOTs) that are using this material.

I have manufacturer information already. I also have local approval letters from our state DOT and one county. The state has apparently installed thousands of feet of this pipe. I have not talked to their engineers yet. I am looking for any information from agencies or consultants on this forum with direct experience with this pipe. I have been told it has been used for years in Australia and perhaps other countries. But I haven't been given any specific info for that.

I'd call the DOT guys and ask about it. Is this a steel fiber reinforced concrete pipe? or steel wire reinforced concrete pipe?
