PT&P custom designed these personnel protection shields for a power plant in Wyoming. The personnel protection shields are used when insulating the line is not necessary, but operating temperatures require safeguarding personnel from coming into contact with the pipe. These shields are designed for an 8” diameter pipe operating at 1050°F. They are fabricated from carbon steel and range in lengths up to 36”.
Piping Technology & Products, Inc. recently designed and fabricated F-type variable spring supports for a plant in Peru. The variables are fabricated from carbon steel, hot-dipped galvanized and a gloss aliphatic polyurethane topcoat was applied for corrosion protection. PTFE, 25% glass filled, slide plates are bonded to the top of the load flange to reduce the friction caused by lateral movement. The variables range from 9.5″ to 11.5″ in height and are designed for a travel range of 1/8″ upward to 3/16″ downward. To ensure quality, standard load testing was performed prior to shipping.

PT&P custom designed these Pipe Spools for a plant in Texas. pipe spools are relatively short assembly, consisting of a pre-determined length of pipe welded to a specified fitting (tee, elbow or reducer) or valve (gate or ball), with flanges typically welded at each end of the pipe. The materials used are carbon steel A36 for flanges and plates, A 106 for pipe, and for stud/nuts A193 B7. This order contained 2 pipe spools, ring retainer, pad eyes, & mount supports. Operating loads were 2200 lb. with standard shipping.
Piping Technology and Products, Inc. recently designed and fabricated B-Type variable spring supports for a plant in Texas. The operating loads range from 4,000 lb. to 17,000 lb. The variable springs are fabricated from galvanized carbon steel, have neoprene coated steel spring coils, and are designed to operate in environments up to 750°F. They have an overall height range from 3 ft. to 8 ft″. To ensure quality, standard load tests were performed prior to shipment.
Pipe Sizes: 2″, 3″, 4″, 6″, 10″, 12″, and 16″
Length: 4″, 6″, 10″, and 12″ (can provide sizes up to 48″)
Material:
Vinyl Resins
Design:
Up to 400°F
Testing:

PT&P fabricated 323 FRP wear pads for an oil refinery in Texas. The wear pads are for pipe sizes of 2″, 3″, 4″, 6″, 10″, 12″, and 16″, and vary in lengths of 4″, 6″, 10″, and 12″. They were fabricated from vinyl resins, and are designed for operating temperatures up to 400°F. The FRP pads are secured to the pipe using an epoxy adhesive to protect the uninsulated pipe from the metal support structure. Standard visual and dimensional tests were performed prior to shipment.

Closure Flange Support Hinges for Supporting Medium to Heavy Duty Blind Flanges
Presently, blind flanges are used to provide an airtight cover to various piping systems that include pipelines in the oil industry, heat exchangers, ships, tanks, etc.
Routine maintenance requires the heavy duty blind flange to be removed for cleaning and repairs. However, for these types of flanges, it is quite difficult to disassemble, clean and repair. It typically requires employing a forklift, crane, or other lifting devices. This can require excessive man-hours, and the alignment of the flanges can remain unpredictable.
PT&P introduced a closure flange hinge with specially designed self‐locking bolts and two self-lubricated hinge studs to support the blind flange when all the fastening bolts are removed for maintenance or replacement. The blind flange can be opened like a “door” with little effort. Our product opens up to 180 degrees, providing full accessibility to work on the pipeline, heat exchanger, or other equipment.
To solve the issues, PT&P invented two versions of closure flange hinges for blind flanges: temporary / removable hinge and permanent / fixed hinge
PT&P recently designed 159 permanent and removable hinges for up to 72″ diameters, We can accommodate for larger sizes upon request.
PT&P custom designed, fabricated and provided installation oversight for sixty-five personnel protection shields for a refinery in Texas. The personnel protection shields are used when insulating the line is not necessary, but operating temperatures require safeguarding personnel from coming into contact with the pipe. These shields are fabricated from carbon steel with a two-coat paint system. They are 11” diameter, and range in lengths up to 48”.
15,000 – 30,000 lb. Load | -112 F | +/- 2″ Movement
Over 300 pre-insulated pipe supports were custom-fabricated for a cryogenic pipeline at an LNG facility in Louisiana. High-density polyurethane foam was used for insulation, with thicknesses ranging from 2” to 4”. The cold shoes are for pipe diameters ranging from 6” to 24” and are fabricated from carbon steel with a hot-dipped galvanized finish. They are designed for temperatures down to -112°F, movements of +/-2”, and operating loads ranging from 15,000 to 30,000 lb. Standard quality control tests were performed prior to shipment.
PT&P designed Micarta® block assemblies for placement beneath the saddle support of a vessel at an oil refinery in Texas. These insulated supports measure 2” x 12” x 81” and include PTFE, 25% glass-filled material bonded to the top of the Micarta®. Micarta® consists of glass fabric with an epoxy resin, which provides great insulating characteristics and superior physical properties. The blocks are designed to prevent cryogenic temperatures down to -454°F from transferring past the base of the support to the supporting steel or foundation. Visual and dimensional tests were performed prior to shipment.
