Universal Snubber Test Facility

About

Universal Snubber test Bench facility has been designed, manufactured, assembled and supplied by M/s Neometrix Engineering Pvt. Ltd based on Noida, India.
Hydraulic Snubber used in sodium piping systems is designed for seismic loading to reduce the seismic induced forces on these piping systems. Nearly 500 numbers of Snubber are installed on various sodium piping with diameters ranging from 15 NB to 800 NB. Load capacity and stroke length of this Snubber vary from 17.5 KN to 240 KN and 140 mm to 245 mm respectively depending on the support locations and size of the piping system.
Performance of this Snubber has been tested at factory as a part of quality assurance program during manufacturing. The Snubber is connected to the piping by means of yoke type clamps. In service inspection (ISI) of the installed Snubber needs to be conducted to ensure no degradation of their performance during the service life in the reactor.
ISI of Snubber is done as per the guidelines of ASME BPVC Section XI Division 3 :- “Rules for Inspection and Testing of Components of Liquid Metal Cooled Plants”. Sample sets of specific number of Snubber are selected for the performance testing during inspection intervals specified as per the ISI program of the plant. A Snubber test facility needs to be installed for this purpose. This document gives the conceptual design and working principle of Snubber test facility for in service performance tests of the Snubber used in the plant.

  • 2. It is used to test HP Pump of HTFE-25. It is designed for functional testing of HP Pump. a. Free Flow Test b. Load Test

    • Key Features

      ....
    • It has separate power packs for both the fluids i.e. ATF Power pack for ATF Fluid, OX Power Pack for OX-27 Oil.
    • This Rig is designed for high temperature Application. It works on 200 deg. Celsius.
    • Two Dedicated heating systems have been integrated with this Rig to raise the temperature of OX-27 Oil.
    • In both Power Packs insulated tanks are being used, which is good for safe operation and safety of operator.
    • This rig is designed in such a way, that it’s OX power pack is in its left side, ATF Power pack is in right Side and test bed is in Centre.
    • A big Test bed have been provided for smooth testing of UUT’s.
    • All piping is being insulated for safe operation and maintenance.
    • It comprises with DAQ System.
    • This rig can test several components at a time, together or separately.
