Sourcing from all the good API 5CT casing pipe manufacturers in China, Octal is working on providing high quality casing pipe with most competitive price. Especially for the the grades J55/K55, N80-1 and N80Q casing. Moreover, Octal is engaged in providing various premium connection casing pipe, for the server working conditions. API LTC and STC Make-Up Procedure - Torque or Vanish Point I see API used on drill pipe all the time, just not shoulder. I meant ultra SF not STC for failed joint. Is it not taboo to put PTFE tape on API connections to get a seal without having to apply much torque. Can it not cause connection to gall when you back-off and tape unwinds not to mention possibility of unzippering thread depending on amount.

The American Petroleum Institute (API) recognizes the basic types of joint connections:Asymmetrical and Trapezoidal thread buttress coupling; Coupling without the extreme-line casing with trapezoidal thread; Rounded thread (long and short) coupling; The long thread casing (LTC) has 8 threads per inch compared to short thread casing (STC). Tubing Torque for Long-Thread Chart Download Tubing The long thread casing (LTC) has 8 threads per inch compared to short thread casing (STC). Tubing Torque for Long-Thread Chart The Long-Thread Chart of Tubing Torque specifies the Outer Diameter (OD) in inches, the weight measured in lb and ft, and the grades of casing pipes that differ in hardness, yield, and tensile strength.
