PT&P custom designed C-type constant spring supports for an oil refinery in the Virgin Islands. They are fabricated entirely from 304 stainless steel to support piping in a highly corrosive environment. The design loads are 7,000 lb., 9,500 lb., and 11,000 lb. with movements of 2-1/2″ and 3″. The constants measure 29″ L x 22″ W x 20″ H. Standard load and travel testing was conducted prior to shipment.

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.

These slide plate assemblies are comprised of 3/32″ thick PTFE, 25% glass filled slide plates bonded to 1/4″ thick hot dipped galvanized carbon steel backing plates. They measure 139″ long by 11-1/2″ wide, and were designed for a pressure of 2000 psi at -320°F to 500°F. PTFE, 25% glass filled material provides a low coefficient of friction, is easy to install, does not require surface treatments, or grouting, and is unaffected by weather conditions. These type of slide plates are typically installed on top of a concrete pillar under a large vessel.

Piping Technology and Products supplied these cryogenic and axial stop cold shoes for an LNG facility in Australia. A total of 28 assemblies were fabricated with carbon steel, stainless steel and Micarta® G-10 insulation blocks. They were a wide range of lengths from 24″ to 36″, widths from 6 3/4″ to 30″ and heights from 9″ to 10 1/4″. The pipe shoes will support pipes ranging in diameter from 6″ to 48″ NPS in cryogenic temperatures as low as -162°C. A special paint system was used for the carbon steel components to resist rust. PMI testing was performed on the stainless parts prior to shipping.
Over 40 constant spring supports were custom designed to support production pipes in an oil refinery. This picture shows a Fig. 200 U-Type constant spring support.
This picture shows a Fig. 100 B-Type constant spring support.
The constants range in size from 22″ to 30″ in height, 35″ to 85″ in length, and 12″ to 31″ in width. Their load capacities range from 1,800 lb. to 20,800 lb. with a vertical movement ranging from 7″ to 11-1/2″. All constants were fabricated from A-36 carbon steel and painted with a 3-coat paint system. Each constant went through standard load and travel testing per MSS Standards prior to shipment.

These variable spring hangers were designed for a 10″ pipe line in a solar electric generating system. All assemblies were fabricated from A-36 carbon steel with a hot-dipped galvanize finish. The picture on the left shows a structural steel assembly supporting a PTP-1 variable spring and a Fig.80 heavy 3-bolt clamp designed for a 3,789 lb. load. The picture on the right shows two PTP-2 variable spring hangers welded to a structural steel beam designed for a 675 lb. load. Each pipe hanger assembly went through standard load and travel testing prior to shipping.

These 200 E-Type horizontal constant spring supports are fabricated from A-36 carbon steel with a hot-dipped galvanize finish. The pins made for constants operation are A-322-4140 high strength carbon steel. The constants range in size from 22-3/4″ to 26-1/4″ heights, 60″ to 90″ lengths, 18″ width, and 19-1/2″ to 23-1/2″ in coil housing diameters. They are designed for 23,160 lb. to 33,700 lb. loads and 6-1/2″ to 14″ of total travel. A total of sixteen assemblies were custom designed for a fired heater radiant manifold. Each pipe hanger assembly went through standard load and travel testing prior to shipping.
