API 5CT J55 Casing Tubing is a API 5CT Oil Casing Pipe & mainly used for oil well drilling

In addition to the method of construction, the pressure capacity, cost, and the application of each kind of pipe vary from the other.

Based on the NPS and schedule of a pipe, the pipe outside diameter (OD) and wall thickness can be obtained from reference tables such as those below, which are based on ASME standards B36.10M and B36.19M.

First of all, they have many differences in manufacturing processes, which are as follows:Concentricity, Welding performance, Grain size, Strength, Corrosion resistance

Seamless pipes are manufactured by extruding the metal to the desired length. Thus, they do not have any joint in its cross-section throughout its length.

Cold Drawn Seamless Mechanical Tubing (CDS) is a cold drawn 1018/1026 steel tube which offers uniform tolerances, enhanced machinability and increased strength and tolerances compared to hot-rolled products.
