Lowery Information

We have over a hundred years combined machining knowledge to produce our product, whether it's milling, lathe work or to make tooling to produce our products. Some of our employees have been working for us for thirty years. Most of our smaller tubing heads are made out of ductile iron. They are cast using ASTM 65-45-12. Our foundries are located in the Midwestern part of the United States, this ensures our customers we only use domestic foundries so a good quality casting is what you are buying when you buy a Lowery well head, meeting a National U.S. standards. Slips are the most integral part of the wellhead; they hold the casing or tubing to ensure a good grip on the pipe. We use solid bar a hot finish 1018, 1020 conforms to ASTM A 576 is a low carbon steel which has good case hardening properties. ASTM stands for American Society for Testing Materials. After machining our slips they are then heat treated to a Rockwell C scale for hardness testing to a 47-52 and .020 to .025 deep. This heat treat process ensures that our slips are going to perform to their maxim load weight. We require only domestic made material so we can hold these types if tolerances which gives our customers a quality product they deserve. Our casing heads are made from heavy wall tubing a grade of 1026 hot finished seamless tubing that meets ASTM standard of A 513. Here again we request domestic material so we can meet the standards we have been giving our customers the last thirty years.
