They are fabricated from A36 carbon steel and underwent standard load and travel testing prior to shipment.
PT&P designed G-Type variable spring supports for a chemical plant in Texas. The variables are comprised of two standard spring housing joined together with an intermediate bridge assembly. The bridge assembly is customized to match existing site conditions which allows for use in applications with limited space or interferences. The variables are fabricated from carbon steel with a hot-dipped galvanized finish. The assemblies were designed for a total operating load of 23,522 lb. with a downward design travel of 3/8″. Each assembly underwent a standard load test prior to shipment.
Fronek Anchor/Darling Enterprises, a division of PT&P, designed snubbers for a LNG facility in Texas. These Fig. 511 AD hydraulic snubbers range in size from 76″ – 85″ piston-to-piston and are fabricated from carbon steel. They are designed for a maximum load of 32,000 lb., 6″ stroke and have a 4″ diameter cylinder. 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 damage and possible failure of the piping system. A cycle test throughout the full stroke from zero to fully extended was performed prior to shipment
PT&P designed cryogenic trunnions with 2″ thick G-10 block insulation for an LNG facility in Australia. The trunnions are fabricated from 10″, 12″ and 24″ diameter pipe. The upper sections are fabricated from stainless steel pipe and plate while the lower sections are carbon steel. These insulated supports are designed for temperatures down to -300°F and operating loads of 4,990 lb.
PT&P manufactured cryogenic pipe supports for a 30″ diameter pipeline in an LNG facility located in the UAE. These cold shoe anchors prevent axial and lateral movement at temperatures down to -300°F. The bearing plate is fabricated from carbon steel and the 5″ thick insulation is a combination of high density polyurethane foam (PUF) and Permali®.
PT&P custom designed variable spring supports for catalyst tubes in a furnace for an ammonia plant in Canada. The furnace springs are fabricated from carbon steel and painted with a red-oxide primer to help prevent corrosion. This project required special coils that were within +/- 5% of the calculated spring rate. Over 245 springs underwent calibration test prior to shipment. PT&P has been supplying furnace springs for over 25 years and can customize them to meet your specifications.
PT&P custom designed Fig. 900 bolt cradle supports with slide plates in 3 weeks for a combined cycle facility in Virginia. The supports are fabricated from carbon steel with a hot-dipped galvanized finish. They are 20″ long and range from 1’2-3/8″ to 1’6-7/8″ in height. The cradle supports are designed for an operating temperature range from 300°F to 530°F and are capable of supporting loads ranging from 1,340 lb. to 3,774 lb. with 0.05″ to 3.33″ of axial movement.
Piping Technology & Products designed and fabricated 107 variable spring hanger assemblies for an Oil Sands Expansion Project in a central processing facility in Canada. We fabricated these C-type variable springs from hot-dipped galvanized carbon steel. The design loads range from 3,343 lb. to 3,417 lb., and each assembly underwent a series of tests and detailed quality control inspections prior to shipment.
Piping Technology designed hot shoes with sliding bases for a power plant in Mississippi. The assemblies will be installed on 28″ diameter pipe and include 1-1/2″ thick calcium silicate insulation. Manufacturing fabricated these supports from galvanized carbon steel with a polyethylene base. They are capable of an operating load of 7,200 lb., temperatures up to 1,200 degrees F and an axial movement of +/- 4-1/2″. The shipment was met three days prior to the critical field need date.
The compact spring is ideal for applications with large loads and limited space.
– Minimizes excessive loads on sensitive equipment
– Same load for smaller working range while consuming 25-50% less space
– Ideal for locating under equipment flanges
– Reduces design time, maintenance cost and accidents
These springs are the solution for satisfying excessive nozzle loads for load sensitive equipment, such as pumps, compressors, turbines, blowers, heat exchangers, pressure vessels and storage tanks. In addition, the entire spring support can be made from corrosion resistant stainless steels or other suitable alloys making it ideal for combating aggressive environments like seawater, marine air and harsh chemicals.
A total of forty-five fabricated pipe shoes were designed for large diameter piping in an LNG facility. The saddles are fabricated from 516 Grade 70 carbon steel to withstand low temperatures and have a hot-dipped galvanized finish. They were designed for 30″, 36″ and 48″ diameter pipe sizes.
PT&P designs thirty F-type variables spring supports for a petroleum facility in Canada. The springs are fabricated from carbon steel and with a hot-dipped galvanized finish. The assemblies are internally guided and have a 3,455 lb. operating load. A standard travel test was conducted on the variables prior to shipment.
