Location of pipe alignment guides
Whenever possible, install the expansion joint close to an anchor. Locate the anchor or first pipe alignment guide no more than 4 pipe diameters from the expansion joint. The second guide should be located no more than 14 pipe diameters from the first guide.
The chart on page 23 gives the recommended pipe alignment guide spacing along the balance of the line. For any pipe size and pressure, the recommended pipe alignment guide spacing can be readily determined. Find the pressure on the bottom scale; extend a vertical line from this point until it intersect the sloping line representing the pipe size involved; from this intersection extend a horizontal line to find pipe alignment guide spacing in feet on the left-hand scale.
