Designed for 20″ to 30″ pipe sizes, these HD-2 and HD-3 hold-down pipe clamps were shipped to a gas pump station in South Dakota. The hold downs were fabricated from carbon steel with PTFE, 25% glass filled liners on the saddle portion and base of the pipe clamp. We fabricated a total of 22 hold down pipe clamps and shipped this rush job within one week.

This presentation will cover Pipe Clamps, including Hold-Down Clamps, Riser Clamps, Clevis Hangers, Yoke U-Bolt Clamps and Structural Supports. Learn how the appropriate type of pipe support is chosen based on the different design conditions. Find out how Finite Element Analysis is used in the design process and view the custom pipe supports designed for extreme applications.
These F-Type variable spring cans were designed with PTFE, 25% glass filled slide plates for a local oil refinery. Slide plates are used to reduce the friction between the load flange of the spring and the pipe support. This allows for easier adjustment of the spring’s installed height. These variables include external travel stops. The external travel stops are sometimes referred to as universal travel stops and can be utilized to adjust the installed load (also called the cold load) to other installed loads within the working range of the spring. 113 variable springs were supplied for this job. The variables have an installed load ranging from 95 lb. to 11,000 lb. and an operating load ranging from 90 lb. to 10,703 lb. They are part of a plant expansion and will be used to support horizontal piping in an oil refinery.


These are custom designed big ton variable spring assemblies manufactured for a chemical plant in Brazil. They are fabricated from A-36 carbon steel, with monel rods, nuts and hardware. They measure 18″ L x 26″ H x 26-1/2″ W and are capable of supporting loads up to 60,000 lb. with down travel of .52″. These big tons employ the use of rollers for adequate mobility and are painted to protect against corrosion.
