Why Use Nitrogen for Pressure Testing?

Nitrogen and regulation
Dry (oxygen free) nitrogen (OFN) is used to achieve the pressures required for the pressure tests because it is inert. You must never use oxygen for pressure testing - pure oxygen at high pressure reacts violently with oil and will explode.

What gas is used for pressure testing?

In many high pressure testing applications for leak testing, gaseous nitrogen is utilized as a medium due to its low investment cost. Many of our customers in the oil & gas industry use nitrogen to perform tests on BOPs, SCSSVs, Christmas trees and drilling equipment.

Why is nitrogen used in air conditioning?

Nitrogen is used in air conditioning to purge oxygen out of the copper tube to prevent the formation of scales on the inner surface of the copper tube due to oxidation that can cause damage to the air conditioner during operation.
