Question: 1 / 400

Can you thread schedule 10 steel pipe?

Yes, but only with special equipment

Yes, for small applications

No

Schedule 10 steel pipe is considered to have a thin wall and is typically not designed for threaded connections due to its reduced strength and wall thickness. The process of threading involves cutting into the pipe material, which can compromise the integrity of a thin-walled pipe. Therefore, threading schedule 10 pipe could result in leaks or even failure under pressure because the threads may not be robust enough to withstand the demands placed on them in a gas fitting application.

In practice, thicker-walled piping is preferred for threading because they maintain structural integrity and provide a more secure thread connection. Using schedule 10 pipe in applications requiring threading is generally not advisable, aligning with the answer choice that states threading schedule 10 steel pipe is not permissible.
