Caing pipe is large diameter pipe that serves as the structural retainer for the walls of oil and gas wells , or well bore . It is inserted into a well bore and cemented in place to protect both subsurface formations and the well bore from collapsing and to allow drilling fluid to circulate and extraction to tak place . Steel casing pipes have smooth wall & minimum yield strength of 35000 psi .
Tubing is the pipe used for the transportation of crude oil and natural gas from an oil or gas layer to the surface after drilling is complete . It is made to withstand the pressure generated from the extraction process . Tubing is manufactured in the same way as casing ,except that an additional process know as “upsetting ” is applied to thicken the pipes .
