PT&P designed cryogenic trunnion supports for ethylene loss recovery lines at a plant in Texas. The trunnions were fabricated from 2″ dia. stainless steel pipes and have a maximum height of 3′. They include 6″ x 6″ permali® blocks measuring 2″ thick each. The permali® block isolator is a laminated phenolic material from layers of wood impregnated under vacuum and heat with synthetic resin. The temperature range for these supports is from ambient to -300°F.Read More
Custom designed cryogenic pipe supports were fabricated for an LNG facility in Africa. The shoes range in diameter from 30″ to 72″, 45″ to 88″ in height, 42-1/2″ to 85-1/2″ in width, and 28″ to 33″ in length. The insulation is a high density polyurethane foam (PUF) ranging from 5″ to 6″ thick. The shoe and bearing plates were fabricated from carbon steel with a HDG finish. The jacket was fabricated from aluminized steel and includes a vapor barrier.

The featured presenter, Jerry Godina has over 15 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.
PTP-2 160 C-Type variable spring support assemblies were designed and fabricated for an oil sands mine in Canada. The variables are 8″-12″ diameter, 16″ to 32-1/2″ overall length, and designed for an operating load of 5590 lb. with an upwards travel of 0.787″. The variables were fabricated from carbon steel with a hot-dipped galvanized finish and standard load and travel testing was completed prior to shipment.Read More
These custom designed sway braces and variable spring assemblies were designed for hanger duct work in an aerospace development facility. The assemblies measure 67-1/2″ long with a 14-1/8″ O.D. The variables are a modified F-type spring with a pivoting base and non-standard coil combination, including a nested spring design. The assemblies include fully adjustable travel stops and custom end brackets. They are fabricated from carbon steel and designed for load ranges between 1100 lb. and 9250 lb. with a spring rate of +/- 2.78″.Read More
These custom designed PTFE slide plate and pipe shoe assemblies are fabricated from A 516 Gr. 70 carbon steel and painted to protect against corrosion. The slide plates are comprised of 3/32″ PTFE, 25% glass filled material bonded to 10 gauge backing plates. A total of twenty guided cradle supports were designed for pipes ranging in diameter from 8″ to 30″.Read More
These custom adjustable pipe saddle supports were designed for an oil refinery in Michigan. They will support 24″ and 30″ diameter pipes and range in height from 40″ to 42″. The pipe saddles can be vertically adjusted by turning the middle section of the seamless pipe and the base plates have been pre-drilled to accept anchor bolts. They are fabricated from carbon steel with a red oxide finish to protect against corrosion and were shipped within two weeks.Read More
PT&P designed and fabricated forty-seven hold-down pipe clamps for a coal fired power plant in Louisiana. The hold-downs are fabricated from carbon steel and range in size from 2″ to 10″ in diameter. The HD-3 is an arrestor type hold down used when there is very low thermal movement. Its radius is lined with a belting material that is well designed to absorb shock from vibration.Read More

Our technical experts take you through piping, design considerations, effects on overall configuration, preliminary piping design, initial layout, the total system, introduction to pipe stress analysis, detailed piping design, and how all of this influences pipe support and pipe hanger design.Read More
This PTP-100 Type-G constant spring support is 96″ long by 40″ high and will support a 12,818 lb. load. It has an actual travel of 0.3″ and total travel of 1-1/2″. The G-type constant is comprised of two standard constant spring housing sub-assemblies joined together with an intermediate bridge assembly. The bridge assembly is customized to handle up to 26,000 lb. of hydro load. The G-type assembly allows for use in applications with limited space. Special identification tags were installed in addition to PT&P’s standard name plates per the customer’s request. Standard testing was performed and witnessed by an outside inspector prior to shipment.
