Tubing is a kind of 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 known as “upsetting” is applied to thicken the pipes.
In addition, steel tubing pipe generally is sized to satisfy the expected rates of production of oil and gas. That is because if tubing is too large, we will have an economic impact beyond the cost of tubing oil and gas itself, however, if API tubing is too small, it will restrict the production of oil or gas, and if things continue this way it will impact subsequent economic performance of the well. Generally, tubing is manufactured in the same way as casing, except an additional process known as “upsetting” which is applied to thicken the pipes.
Tubing is the special-purpose pipe that used in the oil, gas and water well to extract the oil, gas and water to the surface. The tubing conforms to API Specification 5CT, 5B and other related standards, authorized to use the API monogram.Standard, EUE and bimetal anticorrosion tubing are available at all sizes in grade J, N, C, L, T, P which all of them conform to API latest specification.
