All the pipe that were used were  produced in the USA, each pipe is coated with a plastic resin where only the ends are left bare. Once the pipes have been welded together a welding inspector visually looks over every pass of welds before the next welder lays down another bead. After the inspector visually inspects every weld, a two man crew x rays the welds to find if any welds may have been damaged from the next welders bead that passed over the one below. Once the x ray comes back certifying a good weld, another crew of individual comes in and sand blast the each area that will be covered in a epoxy that was put on by the factory. Next the pipe crew has a machine which has a coil that wraps around the whole circumference of the pipe that a small voltage is passed through the coils to detect any bare metals spots that will be patched before they are lowered into the trench. Next a crew uses dozers with side booms to lower the pipe into the ground, the side booms have a cradle that uses plastic rollers to protect the pipe from being scrateched before it is lowerd to its finale resting place. Next the survey crew comes in and shoots each weld which  is documented in the data collector as to who made the pipe, who weere the welders, the welding inspector, as well as the x rays techs. All this inforamation is keyed into an attribute table in the data collector, that way the pipes location can be relocated to with in .003 of a foot. The machine that backfills the trench is called a padder, the padder removes all the big rocks before the soil is used for backfilling. Next the pipes are cleaned of debris by the use of different kind of apparatuses that are called "pigs" after the pipe has been cleaned of debris the pipe is filled with 2500 to 2800 psi pressurized water which needs to maintain that form of pressure for a spefic amount of time. The pipe will never see that kind of pressure when it begins service but the steel pipe is actually designed for around 3000 psi. And you know who is responsible for all these safety procedures the company whose product is being transferred through that pipe. That company spends 100,000 of thousand of dollars just in the inspection of those pipes to insure that each pipe will last decades. Also the pipes are cleaned using a pig on a strict maintenance schedule to ensure that pipe is flowing at optimum performance. That way when an accident occurs it can be detected and fixed immediately to be put back into service. If the public knew what i seen first hand it would of put a lot of those people who thought that the pipes where put together without strict safety procedures. Then when the dust settles it would be about what is really the whole problem to a pipes location which is money nothing more.The oil companies are constantly replacing old pipe that has been in service for decades the pipes are no different then the arteries that are in our own bodies a peroferin wax eventually builds up making the pipe to expensive to be repaired so it must be replaced. I could say more I won't but we have only seen the tip of the ice berg when it comes to transporting crude over land someone knows something that the rest of us will never fully know until it's being piped over thousand or miles of new pipeline.</blockquote>
