What is trenchless pipe rehabilitation?

Pipelines running under the surface of a city carrying water, gas, or oil need pipeline rehabilitation due to aging or corrosion. The repair is done using trenchless rehabilitation that involves the repair or replacement of underground pipelines that have been damaged. The old ways of underground pipeline leak repair may be impractical and costly. They are also disruptive and cause adverse effects on the environment. Therefore trenchless technology is carried out with very less or no digging at all. It is faster, less disruptive, and eco-friendly. Here is a list of reasons why pipeline installation companies hire people to do the rehabilitation. Structural repair needed  Infiltration to be removed The capacity of the pipeline needs to be increased Damage caused due to aging  Damage caused due to natural disasters Failure due to manufacturing default  Damage caused by excavation Damage caused by corrosion Pipeline installation companies may use casing insulators to pr...

What is the difference between tubing and casing?

Tubing is used to transport oil or gas and   casing insulators   protect these tubes. The casing pipeline keeps the main pipe safe. When the pipelines are crossing through any barrier, a   link seal   helps to seal the penetration. The   end seal   helps to ensure that nothing enters between the space between a carrier pipe (tubing) and a casing pipe. Link seal is oil, gas, fire, and extreme temperature resistant. Casing insulators  help in preventing: Contamination of freshwater, Instability in upper formations, Isolating zones that have different pressures while drilling. Casing insulators  are horizontal in shape. Casing pipes are made from steel. Located near r i vers, highways, railroads, and other such areas, pipelines are inside casings. Casings size can be 20inches to 7inches run through drilling hole sizes of 24 inches, 17 and a half inches,12 and a half inches, and 8 and a half inches. Tubing is usually cylindrical in shape. It can be ro...
