Various Applications

Helium Leak Detection services performed for the following applications

Pipeline/Heat Exchanger Inspection

We also offer service of testing of minute leaks using Helium gas for equipments like Columns, Reactors, Exchanger, Vessels, Pipelines and Oil Platforms by positive pressure method. Typically, in these cases, we pressurize the equipment / pipeline with Nitrogen / Helium in the ratio of 90:10 to the testing pressure required by the client and check for leaks in all probable areas. Even minute leaks can be identified using our Sensitive Helium Spectrometer. We use specially designed booster pumps for high pressure testing application We have undertaken such jobs for two new offshore platforms top sides, a flare platform and an interconnecting Bridge for L & T Ltd. INDIA.

Condenser Tube Leak Identification

This will be done, when the unit is in partial isolation or full shut-down provided vaccum pump should run and to arrange steam passing

Critical Valve Leak Testing

We do critical valve leak testing inspection by Helium Leak Testing

Hydrogen Cooled Generator Leak Inspection

In thermal power plants , we carry out Hydrogen cooled generator leak identification either unit is offline/ online, we will also undertake stator conductor inspection when the unit is offline. Our Engineers are well trained in carrying out the test and to interpret the results accurately. The job will be carried out by ASNT Level II Certified Engineers.

About Arudra HLD

STATE OF THE ART - inspection technique to detect leaks

Arudra Engineers introduces a state-of-the-art inspection technique to detect leaks in the negative pressure parts of Steam Condensers,.Air-in-leakage is one of the worst obstacles of the Condenser's vacuum system, which undermines the performance of the equipment.Air-in-leak results in blanketing tube surface from the steam side thereby reducing heat transfer efficiency, as air is a bad conductor of heat. Also the back pressure increase due to air in leakage causes an increase in dissolved oxygen in the condensate resulting in deposition in water wall and super heater tubes of the Boiler, turbine blades thereby leading to generation loss, extra fuel consumption etc.

Hence an early detection of leaks and arresting them would definitely improve the performance of the condenser. It is very important that the negative pressure part system of the condenser / turbine should not be neglected at any cost.

We follow highest safety Standards, HSE policy and job will be carried out by ASNT LEVEL II Certified Engineers and Detailed Service Report Will Be Issued after the job completion.



WORKING PRINCIPLE OF OUR HELIUM LEAK DETECTION TECHNIQUE

Our procedure involves spraying of a tracer gas – Helium on all the suspect areas. Helium being a lighter gas than air, gets sucked into the system due to difference in pressure in case a leaking spot is present.

Helium which got sucked into the negative side of the Condenser is then sucked out through the air removal system along with the non-condensables and a sample of this ejected mixture is passed through our Mass Spectrometer to identify presence of Helium.

As the Spectrometer is extremely sensitive, even minute leaks can be identified instantaneously.
We will categorize the leaks as Small, Medium, Large and Very Large. This classification will help in planning the maintenance program.
