    reservoir piping Material

    Go to WwW.performancepipe.com for helpful design information on HDPE pipe. We were formerly Driscopipe and Plexco. The site is a little confusing right now but try back later if it is too difficult to navigate. I agree with all statements here, I would recommend that who ever does the...

    Asbestos Cement Pipe Fittings

    Also try JCM, Romac and Smith Blair. All make mechanical fittings for use on HDPE. Depending on the circumstances you may need to install a thrust anchor on the HDPE to prevent it from pulling out of your connection. I imagine you will probably find a repair sleeve will work well - but it is...

    Plastic pipe and U.V. resistance

    HDPE that is produced with 2% carbon black will provide an almost unlimited outdoor storage life. HDPE pipe that is not black will have a limited service life in the sun. HDPE is inherintly better than pvc against uv degredation. The real design issue, as stated by smckennz, is how hot the...

    HDPE Deflection

    go to www.performancepipe.com formerly driscopipe and plexco. Cold field bend radius of HDPE is function of DR and OD. MINIMUM Bend radius for common drs are as follows: DR9 or thicker = 20 times od DR 9 to DR13.5 = 25 times od DR 13.5 to DR 21 = 27 times od greater than DR 21 = 100 times...

    siphon collapse

    1PE, Check out our website, www.performancepipe.com. Request an engineering CD. There are some calculations for unconstrained buckling on the CD plus many more design calcs. If you have questions call me. Kevin Deal Performance Pipe 936-321-8940

    HDPE Pipe Abrasion Resistance

    mrf, Some good comments from others here regarding HDPE. I work for a polyethylene pipe manufacturer. [thumbsup2] I have not seen the studies myself but have been told many times that HDPE can outperform steel in terms of abrasion resistance. If needed I can try and find that data. Of...

    Potable Water Distribution Line Design

    cuzisthe1, Wow, interesting repair. If a repair is being made under water, the only real option is mechanical fitting. Depending on the DR you may need a stiffner inside the HDPE pipe. This will prevent the pipe from toe-ing in and allow for restraint. Again, make sure that the fitting is...

    Soil Resistance on Buried Pipe

    Stanier, I tried to send you an email but it was returned. What is your email address? Thanks.

    Restrained joints in casing

    If you use HDPE pipe inside the casing or for the casing itself, you will not need to restrain any joints at all. (Except for the PVC to HDPE connections, of course) Installation may be easier with HDPE as well. check out www.driscoplex.com, good luck.

    Siphon pipe-- maintain empty or full?

    I agree completely with dicksewerrat. Plastic pipe would not corrode and eliminate your issue. Consider HDPE or pvc.

    Submerged HDPE water pipe costs?

    Gungadin, I happen to work for an HDPE pipe manufacturer and am familiar with those types of projects. Check out our website for literature and technical information www.performancepipe.com . For cost estimates on the pipe you can get them from one of our distributors who are listed on the...

    PRESSURE SURGE

    Stanier and Pumpdesigner, There is a fusion equipment manufacuterer that makes a product called the DataLogger. This allows the user to record the critical parameters during each Polyethylene pipe fusion. Have heard from many that this is a great tool. Here's the link ...

    PRESSURE SURGE

    Thank you for your comments Stanier, very informative. Just FYI, Driscopipe and Plexco have combined to form Performance Pipe, a division of Chevron Phillips Chemical. The new website is www.performancepipe.com A lot of helpful engineering information can be found on this site about HDPE pipe...
