Fugitive Emission Testing a 1” ball valve

One ball of size 1”, Class 150 was tested for fugitive emission at 19 bar operating pressure and 200 C temperature using Helium as the Test fluid with 500 numbers of Mechanical Cycles and two thermal cycles as per ISO 15848-1. Sniffing probe method was used to measure the leakage flow rate from the stem seal and body bonnet seal.

Low temperature Testing of 450 mm NB butterfly valve

Valve size of 450mm NB with pressure class of ANSI 150 was tested for seat and shell leakage at 19 bar operating pressure with ambient temperature and –52 deg C using Helium and Nitrogen as test fluids for intervalve (India) Pvt. Ltd., Pune. Test was performed as per customer specification 23858- ODL-3PS-PV00-0002. Sniffing probe method was used to measure the leakage flow rate from the stem seal and body bonnet.

Proof of design Testing of 900 mm NB butterfly valve

900 mm size Butterfly was tested at FCRI on 27/10/2007 to 12/11/2007 for a total number of endurance cycles of 5000 at 10.5-kg/cm2 pressures as per the ANSI/AWWA C504-87 standards. Along with this test, performance test, disc strength test, seat leakage tests were carried out and the valve was passed all the tests.

Fugitive Emission Testing a 2” control valve

Control valves of size 2”, Class 600 were tested for fugitive emission at 105 bar operating pressure and 200 C temperature using Helium as the Test fluid with 20000 and 100000 numbers of Mechanical Cycles and two / four thermal cycles as per ISO 15848-1. Sniffing probe method was used to measure the leakage flow rate from the stem seal and body bonnet seal

Endurance / Proof of Design Testing

Endurance testing of Hydraulic cylinder

Endurance testing of a 75 mm size hydraulic cylinder with operating pressure of 140 bar with servo system 68 as operating fluid is being tested for M/s Rane, Chennai for proof of design as per SAE standard. The cylinder will undergo 100000 cycles with full stroke against the rated pressure

Design / Fabrication of Facility

Design, development & commissioning of cyclic pressure facility

The cyclic test will be done with an exclusive facility for cyclic application of pressure inside the test specimen. The set up comprises of a pressure and flow generating mechanism, a system for applying the pressure as per the test requirement, a recording mechanism for recording the test history, control mechanism for controlling the application of pressure, cooling system to maintain oil temperature within allowable limits and safety mechanism for over pressure

Design, development & commissioning of Jet cavitation erosion facility

This facility produces a submerged cavitating jet, which impinges upon a stationary specimen, also submerged, causing cavitation bubbles to collapse on that specimen and thereby to erode it. This is done as per ASTM G 134

Design, development & commissioning of Burst test facility

Test bed comprising of a hydro-pneumatic pressure booster, pressure gauge and associated instrumentation. This will be operated pneumatically and can be controlled manually. This set up can be used for hydrostatic test as well as burst test. The operating pressure will be 1600 kg/cm2 with a nominal flow rate of 150 cc/min

Design, Fabrication & commissioning of Snout level control system

A snout level control system was designed, fabricated, commissioned and handed over to Nuclear Power corporation, Mumbai. The level of water in the tank was controlled by the flow rate through weir connected to the outlet piping. In the present case , a system was designed to have the required flow as inflow to the system. The water coming to the tank was collected in the outlet tank through the weir provided. The minimum level of water required for the rated flow will be obtained for different configuration of the weir. Simulation of different configuration of the weir were carried out to have optimum performance.

Pump / Sump Studies

Experimental study on the Circulating water intake system

Objective of the experimental study is evaluating the effects of sump geometry, location of suction piping and anti vortex devices on the vortex free running of the pump. The effect of step at the inlet, salinity and temperature on the generation of vortices at varying flow rate through the pump will also be studied. Two bell profiles will be tested with varying the length of the bell portion. The effect of submergence will be studied for varying flow rate for all the cases of sump profile and bell profile will also be studied.

Specialised Testing

Gravel test on meter cluster

The meter cluster under test was placed at a distance of 350 mm from the gravelometer used for the test. Gravel test was performed with a line pressure of 4 bar air, 10-12 mm gravel size. The test meter was placed perpendicular to the plane of the gravelometer. A single stone was made to hit the meter by putting it in the hood for about 3 secs. This whole set up was made to run for about 1 minute. The test was conducted at ambient temperature of 25 ± 2.5 °C
