100-C Constant Spring Supports with Double Lug Suspension

These figure 100 C-type constant springs were manufactured from A36 carbon steel for an oil refinery in Canada. Each constant was designed for 7" of travel with a load of 35,144 lb. They measure 21.5" W x 42" L x 80" H, and were specially designed to match a competitor’s dimensions in order to fit in the required application.

Ever wondered just how important it is to regularly walk through your plant to ensure proper functionality of all pipe supports in the piping system? Understanding the critical nature of properly functioning pipe supports and how they contribute to the overall system, one should thoroughly inspect each component for proper operation during different phases of the life of the unit.

Insulated Pipe Supports for Temperatures as Low as -260°F

These cryogenic supports (also known as cold shoes) are fabricated from 20 PCF polyurethane insulation, weigh 650 lb. each and are designed for 30" diameter pipe. They are comprised of a carbon steel base plate and bearing plate, a vapor barrier and an aluminum jacket. The supports are designed for temperatures as low as -260°F, and measure 27" length by 44" height. A total of thirty-four supports were fabricated for natural gas applications, including storage and transport.

A "U-Type" and 6 "C-Type" constant spring supports were designed to support piping in a corrosive environment located off-shore in Malaysia. The U-Type measures 21" x 25" x 57" and C-Types range in size from 11-5/8" x 17" x 4" to 18-3/4" x 32" x 80".



The constants are fabricated from A36 carbon steel with a fluorocarbon coating on the pins. The frame, housing, and all components were coated with a 3-coat paint system to resist corrosion. Standard load and travel tests were performed prior to shipping the constants on a rush basis.

ASME Code Pig Launchers and Receivers

Safety Locking System

One starter key per launcher/receiver is kept in a box located in the control room. Each lock is executed with two keys. When the first valve is opened with this starter key, it releases the second key. This key is transferred to next valve which releases second key from that valve and so on and so forth. This process guides the operator through the specified sequence for opening and closing valves with unique a key for each step.
