General Info: PIPE LASERS are designed for one function...guiding the laying of pipe from one point to another in a straight line. By carefully aligning the laser beam to the correct grade and line, pipe sections can be set end to end using the laser beam seen at the end of the last pipe on a "pipe target" as a reference point.

The slant of the laser beam can be accurately adjusted to follow the design specifications of the project. Many plans give the slant of the pipe as SLOPE. Most PIPE LASERS express their readings as PERCENT GRADE, which indicates the elevation difference in 100'. Therefore, the SLOPE number must be multiplied by 100 to get % Grade. Further information can be found at SLOPE vs %GRADE.

Once the grade is set, the laser beam must be directed on LINE from the beginning point to the termination point. Usually, a TRANSIT is set up over the top of the PIPE LASER and aimed at the termination point. The TRANSIT scope is then turned downward to sight in front of the first piece of pipe. The PIPE LASER beam is adjusted right or left to meet the vertical crosshair of the TRANSIT.

Most current PIPE LASERS have a RF or IR remote to drive the line left or right from the front end of the pipe work. Because the laser beam is static and presents a possible safety hazard if focused in the eye, laser placards and operator cards are required on the jobsite (see OSHA regulations).
