Of all the irrigation types available, hand move sprinkler systems are still one of the most popular and prominent. The typical sprinkler pipe system is made up of mainline pipe, lateral pipe, risers, and the sprinkler itself. The mainline and lateral pipe are also known as coil or tubing and is most commonly made from aluminum. You will find older steel pipe and newer PVC versions as well. In the Salinas Valley the mainline size is primarily 6”. The lengths of the mainline are 30’, 33.3’, 40’, and 43.3’. 

When discussing mainline pipe is it referred to by its diameter and then length. For instance, 6 x 40 would be a 6” diameter pipe 40’ in length. The lateral pipe used in the Salinas Valley is 3” in diameter and 30’ in length. The tubing is sold with plain ends and the connection end is welded on based on the requirement. Hook and latch and drop lock are the major connection end types used. A newer, non-leak version, called RainTite is starting to become more and more popular as well. The PVC version of this system is called Certalok Yelomine pipe and has been used widely in many different areas and starting to make a presence in the valley.
