The approximate length of the threaded portion for a standard 2" steel pipe used for gas lines is typically 1 inch, or 1-0". This standard length is established to ensure a sufficient engagement of the threads when joining sections of pipe, which is critical for maintaining gas tightness and structural integrity.

In practical applications, having a threaded length of around 1 inch allows for proper sealing with fittings and helps to accommodate variations in material thickness and thread depth. This practice ensures that gas lines remain safe and effective.

Other choices may imply either too little or too much threaded length, which could lead to inadequate connections or unnecessary complications in assembly. Specifically, a length of 0-6" might suggest a degree of variability not practical in these applications, while 1-6" may be excessive beyond what is needed for a secure fit. An option indicating a length of 2-0" exceeds the standard threading requirement and could complicate installation or lead to fitment issues with standard fittings.
