Bumper System for Bundled Road Bores (BBS)

     Another successful bundled road bore using JSI's patent pending BBS bumper system.  This time our product was used on a project up in the Northeast USA.  We completed training on the morning of job kick off (though rain required we train in a warehouse instead of out on the right of way).  As you'll see in the photos below, we are installing on some scrap pipe for training purposes only.

We lightly preheat the surface of the pipe to be certain it is above the dew point and to be certain we are efficiently using the epoxy bonding agent in a very thin layer.  Other than preheating and wiping the pipe coating surface clean so that there is no dust, oil, dirt, grease, etc -- we do NOT damage the factory applied coating in any way. 

The epoxy bonding agent is applied to the preheated pipe surface.  The epoxy bonding agent is applied in a very thin layer.  Microns thick rather than mils.  We want a thickness at which we see the solid color of the epoxy we are applying.  The epoxy should be everywhere that the system will be -- and beyond so that inspectors can verify proper application, even at a later date.

Specially formulated bumper is wrapped around the pipe and secured temporarily using tape.  The bumpers will have been cut at an angle so that they fit together properly; forming a round circular shape.

The main sleeve is then wrapped around that bumper (centered) and the closure is secured.  It is critically important that the sleeve is one that has been proven successful in road bore applications; otherwise you are likely to end up with a pile of material that has torn off the pipeline in your bore hole.  

Main sleeve is then shrunk; starting over the bumper and moving to either end.  The sleeve should always be shrunk circumferentially (around the pipe) in a manner that prevents any air entrapment.  The sleeve will conform very nicely to the bumper profile.

For pipelines 12" and larger we recommend utilizing two installers; one on each side of the pipe - working in tandem.  

Here we see the profile of the bumper showing nicely and properly.  This is looking like a very good installation.  Good job to the crew!

We now see that the leading edge sleeve has been applied to the left side of the system.  This offers extra protection to the front end of the system.  

In this installation, the leading edge strip is on the right side of the system.  Another great install by this crew.  BBS Installation Certification cards are on their way to you!  In addition, we are available 24/7 for teleconference, video conference or any possible trouble shooting that may arise.  

Bumpers on Road Bore Conduit Pipe

Conduit Pipe Road Bore Bumpers

     In reality, pipe that will serve as a conduit (meaning it will be filled with cables and hoses rather than transporting fluid) is on different than oil and natural gas pipelines when it comes to the importance of an external anti corrosion coating.

     In both cases, it is imperative that the steel pipeline be protected with integrity from corrosion that can be caused by water and oxygen.  To spend all of that money for these steel conduits, only to have the steel pipe rust away within a few years (leaving your cables and hoses exposed water) would be absolutely insane.  As a result, conduit pipelines (when buried) are almost always coated with the very same types of coatings that are used on pipelines.  Most often, that coating is a fusion bonded epoxy.

     But when pulling through two (or more) different conduit pipes through the same bore hole; at the same time - it is critical that you do something to prevent one pipe from crashing into the other pipe.  This can really test the impact resistance of your coating and potentially create holidays in the factory applied (or field joint) coating. 

     In those cases, we always recommend our proven BBS bumper system.  Used on pipelines large and small, BBS is the only product on the market with proven before and after evaluations.  In addition, BBS has been used on everything from a two pipe pull through to a massive eleven pipe bundle.

Bumpers for Multi-Pipe Directional Drills

Boring Multiple Pipelines at a Time in Same Hole

  

     As the ground in the USA continues to be ever more filled with our aging pipeline system, in some parts of the country, finding proper right of ways has become more and more difficult.  One way that some companies are choosing to get around this major problem, is to utilize directional drilling technology to lay pipelines without needing to disturb some existing lines.  In some cases, to make things even simpler, many companies are turning to bundled directional drilling applications to lay more than one pipe at a time into the same bore hole.  In cases like this, how can you prevent the different pipelines being dragged through the hole from colliding and damaging one another?  I'm glad you asked; the answer is the BBS - Bore Bumper System. 

     Used on everything from two pipeline bundles to eleven pipeline bundles (yes, we've actually seen this), our BBS bumper system has been used on everything from 4" pipe to 24" pipe.  The system itself historically has been used on pipelines up to 48" (but we've yet to see a bundle that incorporates a 48" line in it).  After numerous uses, the story is always the same; the BBS bumper system if fast and easy to install....and it works like a champ - preventing pipe collisions during the pull through AND during the bore staging.

     We've been fortunate in that we've had the opportunity to inspect this bumper system after it has traveled through the bore hole.  Did the bumper move?  No.  Did the bumper slide?  No.  Did the bumper disappear?  No.  Were there pipe collisions resulting in damage to the factory applied ARO?  No.  Every line came out of the hole exactly like it went into the hole (except for the mud of course). 

     So, if you're bidding a project that needs to include some bore bumpers - look no further - take a close look at our proven, fast and easy to install BBS system.  steve@jsicoatings.com

Pipe Bore Spacers Case Study

Pipeline Bumper Case Study:  20" & 16"

     We were recently given an opportunity to get involved with yet another bundled road bore.  This was a slightly unusual case here in the USA because this pipeline was factory coated with a polypropylene coating and was being installed onshore.  Given our long and successful track record, our product was specified to be the bumper installed on each line to prevent the lines from damaging one another during the pull through. 

     The job went perfectly and we've even already shipped bumpers for the second phase of the project.  Installing on both a 20" and a 16" line was simple.  Utilizing our specially designed bumper system, we locked in place a bumper that is 2" wide and 1" tall.  We do have 2" tall bumper as an option.  In numerous case studies, however, with pipe up to 20" and beyond, it has been shown again and again that with proper bumper spacing, the 1" tall bumpers are sufficient to protect the factory applied coating. 

     So without further ado, let's take a look at some photographs:
