Cluster Spacers for PipelinesMultiple pipes being pulled through a bore at the same time (often called a bundled directional drill) require special preparation to be certain that there won't be significant pipe on pipe violence occurring during that pull. In such a case, a system that serves to keep a safe distance between the assorted pipelines is highly recommended. Sometimes that system is called a Cluster Spacer (though we call ours a bundled bore system: BBS).
Directional drilling is incredibly expensive. Drilling a hole large enough to fit several different pipelines through at a time is even more-so. It is pointless to spend all of that money on the bore itself and then allow the pipeline coating to be so damaged that you're creating problems for years to come. You have to protect your investment. That is where our cluster spacer system comes into play.
