Snubber Testing and Refurbishment Services
Comprehensive Maintenance & Testing Solutions
For over five decades, Curtiss-Wright has been a trusted supplier in the nuclear industry, providing reliable support for large-bore hydraulic snubbers.
Our snubber field services include snubber testing and outage support, repair, rebuilding, and refurbishment of large-bore hydraulic snubbers. We use the TESTAN testing machine and True Test-in-Place (TTIP) technology which avoids unpinning of the snubber or disengaging components from the support structure. This innovative approach significantly reduces maintenance costs and personnel dose. We also offer removal and remote testing of snubber control valves, if TTIP technology is not available.
All Curtiss-Wright technicians are qualified in accordance with ASME NQA-1, and work under the guidelines of ASME Section XI and 10CFR50 Appendix B.
