Hydro testing is a method used to ensure the strength and integrity of pipes and to detect leaks. This process involves filling the pipe with water until it reaches a pressure higher than its normal operating pressure, then maintaining it for a certain period while checking for any leaks or deformations.

Hydro testing is crucial to ensure that the pipe can withstand operational pressure without failing. This testing helps identify potential weaknesses or defects in the pipe, such as cracks, corrosion, or imperfect joints, before the pipe is put into actual system operation.

The common problem encountered in hydro testing and its solution from Eonchemicals is:

Problem Hydrotest Pipa : Pitting Corrosion 

Pitting corrosion

is a serious issue that can arise during hydro testing in the piping industry, where localized corrosion in the form of small holes or “pits” forms on the pipe surface. This problem is caused by the water used still containing chlorides or other contaminants.

Pitting corrosion is dangerous because it can penetrate the pipe wall and cause leaks or structural failures without clear early indications, reducing the pipe’s lifespan and increasing the risk of accidents.

To address this issue, it is essential to use high-quality, contaminant-free water during hydro testing, as well as to use anti-corrosion chemicals to minimize the risk of corrosion during and after testing.

Solution: EonTrim PHT

This is a pipe hydraulic pressure test fluid concentrate, a chemical that provides excellent wetting effects and repels tramp oil effectively, as well as offering highly efficient heat transfer. Additionally, this product has good stability, the ability to quickly settle impurities, provides rust protection, and has a long lifespan when used as a medium in hydraulic pressure testing of pipes.
