Steel casing pipe, also known as encasement pipe, is most commonly used in underground construction to protect utility lines of various types from getting damaged. Such damage might occur due to the elements of nature or human activity. Steel casing pipe is used in different types of horizontal underground boring, where the pipe is jacked into ...
A conductor Pipe is a large diameter pipe that is set into the ground to provide the initial stable structural foundation for a borehole or oil well. [1] The Conductor pipe is the first string of casing and is the largest diameter casing to be installed in a well. It can also be referred to as a drive pipe because it is often driven into the ...
Casing is a large diameter pipe that is assembled and inserted into a recently drilled section of a borehole. Similar to the bones of a spine protecting the spinal cord, casing is set inside the drilled borehole to protect and support the wellstream. The lower portion (and sometimes the entirety) is typically held in place with cement. [1]
The energy consumed in manufacturing ductile iron pipe was 19.55 MJ per kg and volume of emissions released during manufacture was 1.430 kg CO 2 per kg, compared to 68.30 MJ per kg of energy and 4.860 kg CO 2 per kg emissions for PVC pipes, and 1.24 MJ per kg and 0.148 kg CO 2 per kg for concrete pipes of the same diameter.

Tube well. A tube well is a type of water well in which a long, 100–200 millimetres (3.9–7.9 in)-wide, stainless steel tube or pipe is bored underground. The lower end is fitted with a strainer, and a pump lifts water for irrigation. The required depth of the well depends on the depth of the water table.
Multi-screen casing completion: the MLS is installed inside of a multi-screened steel or PVC well. Each well screen segment has a sand or gravel pack between it and the borehole wall, and is thus isolated from monitoring zones above and below by a grout or bentonite seal. The MLS is then constructed inside of the multi-screened well.
Copper fittings for soldered joints. Pipe fittings: 1) Copper (solder); 2) Iron or brass (threaded); 3) Brass (compression); 4) Brass (compression to solder); 5) Brass adapters. PVC fittings. A fitting or adapter is used in pipe systems to connect sections of pipe (designated by nominal size, with greater tolerances of variance) or tube ...
Casing string. In drilling technology, casing string is a long section of connected oilfield pipe that is lowered into a wellbore and cemented. The purpose of the casing pipe is as follows: prevent the collapse of the borehole. prevent formation fluids from entering the borehole in an uncontrolled way (blow out)
