Direct Pipe Pipeline Coating

Pipeline Coating on a Direct Pipe Application

          First let's talk about what Direct Pipe is....I think this video explains it pretty well:

     Isn't that fascinating??  Amazing technology.  Drill the hole and drag the pipe all in one fell sweep. My understanding after having a conversation with one of the engineers out there who has specified that this technology be used is that with Direct Pipe, the hole is much smaller.  It is still a big larger than the pipe itself, but the extra 'space' in the hole is nowhere near what it is when pulling through a bore hole.  He told me that the hole will still be filled with mud which will act as a lubrication.  In addition, the pipe is pushed into the hole rather than being pulled through the hole. 

     I couldn't say what the cost different is between Direct Pipe and standard directional drilling applications. 

     So, just like any directional drilling or road bore application, when selecting your field joint material, you really need to be sure you are choosing the correct product.  For the project I'm talking about, the engineer has elected to use DIRAX to coat the field joints on this line.  It will be about a 3000 foot section of 48" pipe when all is said and done and I have absolutely no doubt that the DIRAX will perform perfectly.  How can I know?  I know because DIRAX has performed perfectly every other time it has been installed -- yes -- even on 48 inch pipe!

     Utilizing a fiber reinforced, heat shrinkable, high density, radiation crosslinked polyethylene backing, the DIRAX is practically impenetrable.  Installed on top of a thin, wet layer of S1301M epoxy primer, DIRAX also exhibits incredible peel and shear resistance.  Without requiring any special equipment -- and with incredibly short cure times (thanks to the way DIRAX is installed), your life has never been simpler.  Give us a call so we can discuss or schedule a demonstration for you.
