Machining on a train bridge mid-construction is demanding. Field System Machining (FSM) has completed several train bridge field machining projects in the past few years, and has recently taken on the tougher challenge of machining on train bridges in active service.
2011 was a banner year for Field System Machining - one of our busiest ever - and while we did our best to please everyone, we were forced to turn away new and old customers alike because we received so many work scopes too close to the outage start date.
During a recent project at a gold mine FSM's on-site machining crew worked six days per week, six weeks in a row, to machine a 125 RMS phonograph finish into twenty-plus autoclave covers and flanges of various sizes.
Industrial fans play a major role in building climate control. Without being able to move chilled air through large commercial buildings or being able to move hot air out of the building, unbearable climate situations occur. Recently we were called upon by a long-time HVAC contractor customer to
Field System Machining (FSM) was recently asked to perform cold cast iron welding at a major American hydroelectric plant equipment repair facility. Since 1978, we've pioneered or refined numerous innovative welding techniques. For example, our revolutionary FSM 01-625 cold cast iron w
Three companies were asked to bid the field machining repairs to New Page Biron Mill's 78 Super Calendar. Two companies declined to bid - Field System Machining bid the work and completed the project in May 2011, completing one half-shift early of our quoted nine shift completion time.
How old are our nation's bridges? The rail crossing on the Illinois River at Morris, Illinois, was first erected in 1888. The 1888 bridge was replaced by a lift bridge in the 1930s. The rail line is abandoned just below the Illinois River, and trains that cross the bridge today serve only the hea
Field System Machining recently completed bolt hole repairs to two steam turbine LP hood crossover flanges, which had damaged threaded blind holes. The blind threaded bolt holes were over-bored, threaded inserts were manufactured in our shop, the over-bored bolt holes were tapped, and the inserts
Field System Machining recently completed on-site portable field machining on a pressure vessel at the Kennametal Engineered Products Group in Rogers, Arkansas. The scope grew as the project continued because the pitting in the pressure vessel was deeper than the client originally believed. About
