The Pipe Support Blog

This week, Piping Technology hosted a meeting at a local Indian restaurant in Houston for the Houston Caesar II User Group and SPED members.  While attendees enjoyed a delectable Indian meal, we presented a technical overview on pipe support engineering and design featuring a variety of products including variable springs, pipe clamps, and pre-insulated supports. The presentation also featured various design tools including finite element analysis, 3D modeling, and STAAD analysis.

The cold shoes are fabricated from a combination of carbon steel, micarta insulation, and stainless steel. They measure 18" x 12" x 10" and are designed for 7" of lateral movement with temperatures as low as -162°C. A total of 16 supports were manufactured and PMI tested. This was a rush order completed in just under 12 weeks for a LNG plant.

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.

Big Ton Spring Supports for a Chemical Processing Plant

A total of 18 big ton springs of various sizes were fabricated from A516 Gr. 70N carbon steel. The big tons were designed in a rectangular configuration in order to match the existing vessel saddle supports and the concrete foundation below the springs. PTFE, 25% glass filled slide plates will be welded on the load flanges to allow horizontal movement in addition to the vertical movements specified. The largest of the big ton assemblies has an operating load of 79,000 lb. with a travel of .706" down.
