Fabricated Horizontal Vacuum Belt Filter Assembly for the Energy Industry

At A & S Fabricating, we have specialized in heavy custom metal fabrications since 1969, providing exceptional quality machining for the largest and most unconventional projects. An engineering firm in the energy sector contracted us to fabricate the horizontal vacuum belt filter assembly shown here. Each component of this assembly was of an enormous size, and when fully completed, weighed nearly 50 tons. To create this assembly, our customer supplied motors, a belt, and rollers, and we supplied and painted the steel frames and some of the components. The steel in the structure was composed of A36 structural steel alloy, in forms that included beams, tubing, angles, pipes, and 3/4” thick plate. To construct these frames, we employed our facility’s full fabricating capabilities, including our saw cutting, shearing, CNC burning, plasma cutting, bending, welding, and assembly services. We provided secondary finishing that included sandblasting and 3-coats of Tnemec spray Endura-Shield paint. Our 110,000 square foot shop can accommodate huge projects such as these, and when completed, the finished assembly measured 123’ in length, 14’6” in width, 8’11” in height, and weighed 97,400 lbs. The pieces were thoroughly tested and inspected for quality, ensuring that our customer’s specifications were strictly followed. Our client appreciated the results, enlisting our services for several additional project partnerships.
