ELIMINATE your FME concerns when machining COLD TAPS, WET TAPS AND HOT TAPS.  Contact us to discuss how our specially designed portable EDM machine can help your plant solve this important issue when installing vent valves.




We continue to develop better ways to provide you the best and most up-to-date resources and control for FME during that time when you have to install valves and can not drain the system.  We provide the latest self contained EDM equipment which can be transported by 2 people to any area of your plant.  Low risk to your plant systems and the most tested positive control of your FME material is here.  Let us visit your plant and discuss our cost savings and of course nearly FME free process to support the next vent valve install.  Contact us to discuss your needs and help solve your FME problems.

McWilliams qualifications were performed to comply with ASME Section XI, IWA-4461.4 and IWA-4461.4.1 (1998 edition, 2000 Addenda). This provides for pre-qualification of thermal metal removal processes, to eliminate the need for metallurgical evaluation following metal removal during production processes.

The test was run by Herquth Laboratory on September 26th, 2008.  It showed a particle size of less than 30 microns that was created by this EDM process.  (Ref. Lab No.  602954-602957)
