Part 1 covered the basics. Here are ten more words you'll hear once you've been on the spread a few days.
Point of Intersect (PI). is the exact location where the direction of a pipeline changes (at a horizontal or vertical bend)
RCE. Rock Construction Entrance rock laid at the entrance to the right of way where it intersects a road.
Two tone. When the right of way and temporary work space purchased by the company is too narrow the excavated soil is used to make a second travel lane higher than the first.
Spacer. The pipe gang hand who sets the gap between joints during fit-up, so the root pass has the right spacing.
Soft shack. A shack covered in a thick tarp moved from weld to weld used to protect the semi-automatic welding operations.
Pre-heat. Heating the weld area to a set temperature before welding. It slows cooling and helps prevent cracking. The temperature comes from the welding procedure.
Lap. Pipeline version of random, when the pipeline section is longer than required, typically cut off during tie-in weld fit-up.
Lower-in. Lifting the welded, coated pipe off the skids with sidebooms and setting it into the ditch.
Alignment sheets. The drawings that show the route from above and in profile, with stations, PIs, crossings, pipe specs, and coating changes. They're the map for the whole job.
Design factor. The number used in the pipe design formula that limits how hard the pipe can be stressed, based on where it runs. Pipe near homes and towns gets a lower design factor, which means a thicker wall or a lower pressure.
Keep it straight in the field
Every one of these ends up tied to a station and a weld number. A tally book keeps that record in your pocket.
