ABSTRACT
This guide describes the design, selection considerations, and installation procedures for the placement of polyethylene pipe or conduit below ground using maxi-horizontal directional drilling equipment. The pipes or conduits may be used for various applications including telecommunications, electric power, natural gas, petroleum, water lines, sewer lines, or other fluid transport. Horizontal directional drilling is a form of trenchless technology. The equipment and procedures are intended to minimize surface damage, restoration requirements, and disruption of vehicular or maritime traffic with little or no interruption of other existing lines or services. Mini-horizontal directional drilling (min-HDD) is typically used for the relatively shorter distances and smaller diameter pipes associated with local utility distribution lines. In comparison, maxihorizontal directional drilling (maxi-HDD) is typically used for longer distances and larger diameter pipes common in major river crossings. Applications that are intermediate to the mini-HDD or maxi-HDD categories may utilize appropriate “medi” equipment of intermediate size and capabilities. In such cases, the design guidelines and installation practices would follow those described for the mini- or maxi-HDD categories, as judged to be most suitable for each situation.

SCOPE
1.1 This guide describes the the specification and re-construction of in-situ pipelines and conduits 2 in. to 63 in. (50 mm to 1600 mm) diameter) by the pulled-in-place installation, into an existing conduit, of circular, radially reduced, Shape-Memory-Polymer Tubular (SMPT) that after installation, re-expands (by “memory”) to press against the ID of the host pipe, thus coupling the interior pipe, by friction fit, as reinforcement to the host pipe. The added SMPT pipe wall restores leak tightness and adds its strength to the host pipe (Dual-Wall Composite-Pipe). It becomes a continuous compressed-fit dual-wall pipeline. Depending upon the SMPT compound used, the re-constructed pipelines or conduits are suitable for pressure and nonpressure pipeline applications such as process piping, raw and treated water transmission, water pipe systems, forced-mains, industrial and oil-patch gathering and transmission pipelines, sanitary sewers, storm sewers, and culverts.

ABSTRACT
This guide describes the design, selection considerations, and installation procedures for the placement of polyethylene pipe or conduit below ground using maxi-horizontal directional drilling equipment. The pipes or conduits may be used for various applications including telecommunications, electric power, natural gas, petroleum, water lines, sewer lines, or other fluid transport. Horizontal directional drilling is a form of trenchless technology. The equipment and procedures are intended to minimize surface damage, restoration requirements, and disruption of vehicular or maritime traffic with little or no interruption of other existing lines or services. Mini-horizontal directional drilling (min-HDD) is typically used for the relatively shorter distances and smaller diameter pipes associated with local utility distribution lines. In comparison, maxihorizontal directional drilling (maxi-HDD) is typically used for longer distances and larger diameter pipes common in major river crossings. Applications that are intermediate to the mini-HDD or maxi-HDD categories may utilize appropriate “medi” equipment of intermediate size and capabilities. In such cases, the design guidelines and installation practices would follow those described for the mini- or maxi-HDD categories, as judged to be most suitable for each situation.
