New Webinar: Pipe Supports for Beginners- Constants & Variables

December 6th, 2012 Comments off

View the recording at: http://info.pipingtech.com/webinar-beginners/

This webinar series was created to explain the basic principles of different types of pipe supports in the simplest way possible. It is geared towards “non-engineers” who want to have a better understanding of pipe supports. This particular presentation will give you a brief introduction to pipe supports and will then solely concentrate on constant and variable spring supports. It will explain the various designs, applications, and details of each support using simple terms and a lot of visual aids. The presentation will conclude with general guidelines of the maintenance and ordering process of constants and variables.

How To: Remove Travel Stops from a Constant

Custom Constant Spring Hangers and Pipe Clamps

The constant spring hangers are manufactured from A36 carbon steel and have custom 4-bolt pipe clamps due to heavy loads. The dimensions are 40″ length x 18″ width x 85″ height and are designed for a 1,784 lb. load with 10″ of travel. The constants will be used to support radiant inlet manifolds and have a unique paint applied due to the highly corrosive condition. The entire pipe hanger assembly went through load and travel testing prior to shipping.

U-Type Constants with Rollers to Reduce Friction

Rollers

This constant utilizes sealed cam follower roller bearings in place of slide plates that are generally used between the moving table and stationary frame. The rollers help to reduce the friction on the table, reduce residual loads which improve constant deviation, and help to restrict table movement in horizontal directions. These U-Type constants are fabricated from A36 carbon steel with dimensions of 28″H x 37″L x 17″W. The boxing, bolting patterns and loading table location are custom designed per customer specifications. The design also includes a graphite plate bonded to the top of the load flange to reduce the friction between the constant load flange and the saddle support above it. The supports are designed to carry 3015 lb. of piping load with an upward travel of 6″. The constants underwent standard load and travel testing before being shipped to an energy plant.

C-Type Constant with Special Lugs

C-Type Constant with Special Lugs

This PT&P 100 C-Type constant spring support was designed in conjunction with special lugs to fit inside of a trolley. The lugs will provide for movement up and down, as well as extensive horizontal movement. This constant was fabricated entirely from A-36 carbon steel with a hot-dipped galvanize finish. The constant measures 16″ wide x 25″ long x 56″ high. It is designed to carry 16,164 lb. of piping load with a travel of 3 1/2″ downward. The lugs will fit within a trolley by a single pin connection. This configuration will prevent swinging by maintaining the constant in an upright position, which will ensure proper functionality and eliminate any load deviation.

Slide Plate on Constant

These custom designed constants will be utilized for a heavy load of 109,000 lb. They are designed for a downward travel of 1 1/2″. In order to support the heavy load and low take-off, the constants are designed with an inner and outer spring coil with the outer coil measuring 56″L with a 18 3/4″ O.D. These U-Type constants are fabricated from A36 carbon steel with a hot-dipped galvanize finish.

The dimensions of the constant are 31″H x 90″L x 32″W. The image above shows a PTFE, 25% glass filled slide plate on top to reduce the friction between the constant load flange and the structure above the support. The constant also includes slide plates between the table and the frame of the constant to reduce the friction on the table and improve constant deviation.
