Pollution prevention and control measures of hydrostatic testing
Date:2020-06-24      View(s):461      Tag:Pollution prevention and control measures of hydrostatic testing

Hydrostatic testing of pipelines involves pressure testing with water to verify their integrity and to detect possible leaks. Chemical additives (typically a corrosion inhibitor, an oxygen scavenger, and a dye) may be added.


In managing hydro-test waters, the following pollution prevention and control measures should be implemented:


(1) using the same water for multiple tests to conserve water and minimize discharges of potentially contaminated effluent;


(2) reducing the use of corrosion inhibiting or other chemicals by minimizing the time that test water remains in the equipment or pipeline;


(3) selecting the least hazardous alternative with regards to toxicity, biodegradability, bio-availability, and bio-accumulation potential; and


(4) dosing according to local regulatory requirements and manufacturer recommendations.
