How should threaded steel piping for underground use be prepared?

Threaded steel piping intended for underground use must be threaded with sharp cutting dies. Using sharp cutting dies ensures clean, precise threads that create a strong, reliable connection between pipe sections. This integrity is crucial, as leaks can pose serious environmental risks and lead to contamination of the surrounding soil and groundwater.

Additionally, sharp dies produce clean threads that facilitate a tighter seal, which is vital for maintaining the integrity of the underground storage system. Properly prepared threads can enhance the lifetime of the piping and reduce maintenance issues caused by improper installation or corrosion at the joints.

Using blunt cutting dies, for instance, could create rough threads that might not seat properly, leading to potential leaks. Non-threaded joints do not accommodate the necessary connection method for steel piping, and threading loosely for easy adjustments compromises the structural integrity needed to withstand environmental factors and operational pressures.
