2. Cured-in-place pipe - Wikipedia

   en.wikipedia.org/wiki/Cured-in-place_pipe

   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).

3. Sliplining - Wikipedia

   en.wikipedia.org/wiki/Sliplining

   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 ...

4. Sanitary sewer - Wikipedia

   en.wikipedia.org/wiki/Sanitary_sewer

   Vertical pipes, usually made of precast concrete, called manholes, connect the mains to the surface. Depending upon site application and use, these vertical pipes can be cylindrical, eccentric, or concentric. The manholes are used for access to the sewer pipes for inspection and maintenance, and as a means to vent sewer gases.

5. Drain-waste-vent system - Wikipedia

   en.wikipedia.org/wiki/Drain-waste-vent_system

   A sewer pipe is normally at neutral air pressure compared to the surrounding atmosphere.When a column of waste water flows through a pipe, it compresses air ahead of it in the system, creating a positive pressure that must be released so it does not push back on the waste stream and downstream traps, slow drainage, and induce potential clogs.

6. Plumbing - Wikipedia

   en.wikipedia.org/wiki/Plumbing

   A pipe is typically formed via casting or welding, whereas a tube is made through extrusion. Pipe normally has thicker walls and may be threaded or welded, while tubing is thinner-walled and requires special joining techniques such as brazing, compression fitting, crimping, or for plastics, solvent welding.

7. Effluent sewer - Wikipedia

   en.wikipedia.org/wiki/Effluent_sewer

   Effluent sewer systems, as well as all sewer systems, can use two methods to transport wastewater to a treatment facility. These methods are gravity and pumping, also called pressure systems. Gravity systems use pipes that are laid on a slight downhill slope to transport wastewater. Effluent pumping systems have pipes that are buried at a ...

8. Heat-shrinkable sleeve - Wikipedia

   en.wikipedia.org/wiki/Heat-shrinkable_sleeve

   The first heat-shrinkable sleeves were introduced [when?] as polyethylene pipeline coatings started to replace bituminous or tape coatings in the oil and gas industry. At the time, the processing for polyethylene to make the sleeve backing was new technology and the adhesives used in sleeves were much the same as those used on pipeline coating.

9. Sleeve (construction) - Wikipedia

   en.wikipedia.org/wiki/Sleeve_(construction)

   For example, a 4" pipe, with 1" of thermal insulation makes a 6" penetrant (1" pipe covering on each side of the pipe), plus two pipe sizes = an 8" sleeve, creating a 1" annulus. In case of insulated piping, the size of the insulation must be taken into account for the intended firestop certification listing .
