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). The process of CIPP involves inserting and running a felt lining into a preexisting pipe that is the subject of repair.
Petroleum-based pipe dope is not intended for use on threaded PVC, CPVC or ABS pipe and fittings since it will deteriorate the plastic. Builders in the US are expected to use thread compounds that meet ASTM F2331 - Standard Test Method for Determining Chemical Compatibility of Thread Sealants with Thermoplastic Threaded Pipe and Fittings Materials or thread seal tape on PVC, CPVC and ABS threads.
Cleaning methods encompass solvent cleaning, hot alkaline detergent cleaning, electro-cleaning, and acid etch. In industrial settings, the water-break test is a common practice to assess machinery cleanliness. This test involves thoroughly rinsing and vertically holding the surface.
Hydraulically activated pipeline pigging (HAPP) is a pigging technology applied for pipeline cleaning. The basic principle is that a pressure drop is created over a by-passable pig held back against a pipeline's fluid flow. The pipeline fluid passing through the pigs cleaning head is accelerated by this pressure drop, forming strong cleaning jets.
The intent of this foaming action is to coat the inside of the drain pipe to dislodge more of the substances that form the clog. Because liquid alkaline drain cleaners are essentially a base dissolved in water, this is denser than water and can sink to the source of the clog. [citation needed]
Roto-Rooter's sewer cleaning service allowed homeowners to avoid digging up lawns and landscaping to reach underground sewer pipes. This breakthrough was a revolutionary concept. In the 1930s and 40s, Roto-Rooter featured an illustration of a mound of dirt over a recently excavated sewer pipe with the caption, "Why put a grave in your yard?"

Tube cleaning describes the activity of, or device for, the cleaning and maintenance of fouled tubes. [1] The need for cleaning arises because the medium that is transported through the tubes may cause deposits and finally even obstructions. In system engineering and in industry, particular demands are placed upon surface roughness or heat ...
