It is a jointless, seamless pipe lining within an existing pipe. As one of the most widely used rehabilitation methods, CIPP has applications in sewer, water, gas, chemical and district heating pipelines ranging in diameter from 0.1 to 2.8 meters (2–110 inches).
Pipe replacement by pipe bursting. Trenchless rehabilitation includes such construction methods as spiral wound lining, sliplining, thermoformed pipe, pipe bursting, shotcrete, gunite, cured-in-place pipe (CIPP), grout-in-place pipe, mechanical spot repair, and other methods for the repair, rehabilitation, or replacement of existing buried pipes and structures without excavation, or at least ...
Insituform's inception was prompted by the invention of cured-in-place pipe (CIPP) by Eric Wood of the United Kingdom in the early 1970s. Its name comes from the Latin phrase "in situ form," which means to "form in place." The first CIPP tube was installed in the UK in 1971 and is still in service today.
It involves installing a smaller, "carrier pipe" into a larger "host pipe", grouting the annular space between the two pipes, and sealing the ends. Sliplining has been used since the 1940s. [1] The most common material used to slipline an existing pipe is high-density polyethylene (HDPE), but fiberglass-reinforced pipe (FRP) and PVC are also ...

Sprayed in place pipe (SIPP) technologies is a trench-less rehabilitation method used to repair existing pipelines, that involves a robotic lining system that develops and manufactures proprietary lining polymeric. SIPP is a jointless, seamless, pipe with in a pipe with the capability to rehabilitate pipes ranging in diameter of .1 to 2.8 ...
A liner is a casing string that does not extend to the surface, being hung instead from a liner hanger set inside of the previous casing string but usually within about 300 feet (91 m) of its bottom. Other than the obvious cost savings, the liner installation allows larger drill pipe or production tubing to be used in the upper portions of the ...
Cement-mortar lined ductile iron pipe is a ductile iron pipe with cement lining on the inside surface, and is commonly used for water distribution. Cement-mortar lined ductile iron pipe is governed by standards set forth by DIPRA ( Ductile Iron Pipe Research Association ), and was first used in 1922 in Charleston, South Carolina .
