Please join us for a webinar Thursday, June 7th at:
10:00 am CDT or 2:00 pm CDT
Subject: Constant Spring Supports Design and Application Webinar
** Webinar is worth 1 PDH Credit for TX Professional Engineers
Date: Thursday, June 7th, 2012

This Webinar will focus on the different types of constant spring supports. Learn about the special features available, in addition to the design of a constant support. View how the different cam/coil configurations produce a unique response to an applied load. Discover the step by step process used to size a spring for your application. Learn about the different attachments, testing, and installation and maintenance procedures. View examples of failed supports provided by our Field Service Division and learn why they failed and how to prevent it. Gain knowledge of the valuable tips used when deciding to adjust or replace a constant spring support, as well as shutdown and isolation procedures.
The featured presenter, Jerry Godina has over 13 years experience as a pipe support designer and manages PT&P’s engineer training development program. He also inspects existing supports, consults on site remediation projects and oversees installation on a regular basis.

A total of 232 variable spring supports were custom designed for a natural gas processing and separation plant. This project included various spring sizes from PTP-1 30 C-type to PTP-4 160 F-type assemblies. The variables are fabricated from carbon steel, galvanized and coated with a special 3-coat paint system to protect against corrosive byproducts such as sulphur. The F-types include 304 stainless steel and PTFE, 25% glass filled slide plate assemblies.


These fabricated clamp-on pipe shoe assemblies were custom designed for a gold mine project in the Dominican Republic. They are composed of a clamp-on pipe shoe subassembly combined with a carbon steel pipe extension. A total of nineteen pipe shoes were fabricated for 3″, 4″ and 6″ diameter pipes. The extensions were designed at various heights to position the pipe line at the correct elevation for a sloping line. When a design includes a closed off section, PT&P’s standard is to incorporated vent holes in order to prevent moisture build-up. They are painted with a two-coat paint system to protect against corrosion and include stainless steel tags to easily identify the product code.

These custom designed pipe shoes were fabricated for main steam piping in a gold mine project. A total of forty-three pipe shoes ranging in size from 20″ to 36″ diameter were designed for temperatures up to 650°F. The shoes ranged in length from 17″ to 24″, width from 20″ to 32″ and height from 3″ to 7″. They are manufactured from carbon steel and have a two-coat paint system to protect against corrosion.

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.

251 variable furnace springs were designed and fabricated for fertilizer production at a chemical plant in Virginia. The furnace cans are carbon steel and painted with red-oxide primer to avoid any potential hazards where exposed to high temperatures. This project included figures: PTP-1-120, PTP-2-150, PTP-2-180, PTP-4-100 and PTP-4-200 variable furnace springs with operating loads ranging from 1,042 lb. to 15,512 lb. A load test on all variable springs was conducted prior to shipment.

Fronek Anchor/Darling Enterprises, a division of PT&P designed and fabricated hydraulic snubbers for a geothermal facility in California. The Fig. 510 AD snubbers ranged in size from 34-3/4″ to 37-5/8″ piston-to-piston and were designed for a 50,000 lb. maximum load, 5″ cylinder size and a 6″ stroke. The Fig. 511 AD snubbers ranged in size from 56-15/16″ to 59-5/16″ P-P and were designed for a 20,000 lb. maximum load, 2-1/2″ cylinder size and a 6″ stroke. Hydraulic snubbers are designed to protect the piping system when a sudden, heavy load is applied (such as an earthquake of high intensity), which can cause serious vibrations leading to complete destruction. A custom three-bolt pipe clamp fabricated from carbon steel was designed to fit in a limited space. A cycle test throughout the full stroke from zero to fully extended was performed prior to shipment.
