Lateral Lining Solutions
The Performance Liner® Lateral System is a unique cured in-place process that allows the installer the freedom to position the liner anywhere in the pipe by inverting through a cleanout. The liner can be directed either upstream or downstream using LMK’s patented guide shoe. In addition, this versatile system is capable of being installed in pipes under foundations, inside walls or in vertical applications. LMK’s Lateral Lining system is truly a no dig situation for renewing lateral pipes since the entire process can be completed through a cleanout. Gasket sealing O-rings are placed at the upstream and downstream ends of the liner providing a verifiable, non-leaking lateral liner that is compatible with all types of piping.
LMK’s lateral liners also include compressible material at the upstream end of the liner, producing a smooth tapered transition to the old pipe. This process renews laterals from 4-8 inches in diameter in continuous lengths up to 130 feet. Inversion tanks come in two sizes (36 inch or 18 inch) and are equipped with a camera port so the lateral liner can be visually inspected under pressure for proper placement prior to the liner being cured.
Standard practice for rehabilitation of existing pipelines and conduits by the inversion and curing of a resin-impregnated tube.
Significance and Use
Purchase the full version of this standard by visiting the ASTM website here.
This practice is for use by designers and specifiers, regulatory agencies, owners, and inspection organizations who are involved in the rehabilitation of conduits through the use of a resin-impregnated tube inverted through the existing conduit. As for any practice, modifications may be required for specific job conditions.
This practice describes the procedures for the reconstruction of pipelines and conduits (4 to 108-in. diameter) by the installation of a resin-impregnated, flexible tube which is inverted into the existing conduit by use of a hydrostatic head or air pressure. The resin is cured by circulating hot water or introducing controlled steam within the tube. When cured, the finished pipe will be continuous and tight-fitting. This reconstruction process can be used in a variety of gravity and pressure applications such as sanitary sewers, storm sewers, process piping, electrical conduits, and ventilation systems.
The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. For specific precautionary statements, see 7.4.2.
