API 5CT L80 Pipe
API 5CT L80 is a grade that is governed by the American Petroleum Institute. The API 5CT L80 Pipe is designed with a chemical composition consisting of carbon, silicon, manganese, phosphorous, sulfur, copper, chromium, nickel, and aluminum. The superior content embedded in the API 5CT Grade L80 Pipes gives them enhanced resistance to corrosive and oxidative media across stress-induced environments. The L80 Pipe can be designed in a range of shapes and dimensions. These pipes possess a wall thickness ranging between 4mm up to 16mm. The high-strength API L80 Pipe is designed with an outer diameter in the range of 12mm to 508mm. These pipes possess schedules between SCH 10 to SCH 160 and XXH. The API 5CT L80 Carbon Steel Line Pipes are designed possessing superior strength. These pipes are utilized to transport high pressure and temperature fluids and gases in the system.
The API 5CT Grade L80 Octg Pipe are common pipe grades that are utilized in oil and gas production systems. The pipes are designed in three major categories. API 5CT Octg Pipe is made up of drill pipe, casing pipe, and pipe grade that is used for tubing type of pipe. The versatile API 5CT Gr. L80 Octg Tubing goes on the inside of the casing pipe as it is a module through which the oil passes through the line. The L80 Tubing is designed with a minimum tensile strength of 655mpa and has a yield strength between 552 to 655mpa. The API 5CT Tubing is generally found in segments of 30 ft with a threaded connection on both ends.
The API 5CT Grade L80 Type 1 Casing And Tubing is a special type of casing that provides protection to piping components in this grade. The versatile grade of API 5CT Casing protect petroleum, oil drilling pipes against wear and tear in harsh environmental systems. The robust L80 Casing shouldn’t be tempered in temperatures below 1150 degrees F, to prevent them from becoming brittle. The dimension of the casing is between 114.3mm to 406.4mm.
