The J.D. Rush Company contracts with our subsidiary, Tryad Service Corporation, to offer our customers pre-designed mill slot perforating. Using multi-spindle milling machines for slotted liners and round hole drilling machines to drill base pipe, we offer a multitude of patterns on 1.900” – 16” casing. Our slot size capabilities range from 0.012” to .500” and ¼” – ½” round holes. All of our machines use a continuous flow of biodegradable coolants to maintain the pipe’s metallurgical integrity.

Tryad can slot or round hole perforate a wide range of materials, such as carbon grades, alloys, stainless steel, and chrome. We are capable of creating complete turnkey packages as easily as we can slot or perforate customer-owned materials.
