Drilling Low Carbon Alloy Steel API 5ST Coiled Tubing
CT100 Seamless Low Carbon Alloy Steel API 5ST Coiled Tubing
The coiled tubing provided by Tiptop meets the highest industry standards and can replace many conventionally operated pipelines. It can be used in a variety of industrial applications, such as milling, drilling, rock fracturing, sidetracking, production tubing, low bottom pressure drilling, wellbore cleaning, nitrogen injection, sand control, cementing, mechanical isolation, logging and perforation. The length of a coil of coiled tubing can reach several kilometers. When it is used, people will wrap it on the spool and straighten it, then push it into the wellbore, and then rewind it to the spool for transportation and storage. We can provide steel grades of CT70, CT80, CT90, CT100, and CT110.
