The derrick supports the crown block and provides a place to stack pipe that is pulled out of the hole. The depth rating of the derrick is related to the size of the rig. The height of the derrick is commonly referred to in multiples of pipe joints (a joint of pipe is approximately 30 ft long). Rigs that can stack double joints of drill pipe are called double derricks, and those that stack three joints are called treble derricks. Part way up the derrick are the monkey board (3) and pipe fingers. The derrickman handles the top end of each stand of pipe from the monkey board during trips.
Trenches are normally four to six feet deep and up to 400 feet long, depending on the number of pipes in a trench. One advantage of a horizontal loop system is being able to lay the trenches according to the shape of the land. As a rule of thumb, 500-600 feet of pipe is required per ton of system capacity.A well-insulated 2,000-square-foot home would need about a three-ton system with 1,500 - 1,800 feet of pipe.Pipe sections are joined by thermal fusion.s a rule of thumb, 500-600 feet of pipe is required per ton of system capacity.
