This custom designed variable spring assembly is comprised of a standard PTP-1-160 type F variable spring with a supplementary extension and load flange with a stainless steel slide plate. The variable is fabricated entirely from carbon steel with a hot-dipped galvanize finish. The extension is schedule 40 pipe, 8″ in diameter and 12-5/16″ in height. The slide plate is fabricated from A240 grade stainless steel and is welded to the top of the load flange. This support will be used underneath a 16″ diameter pipe with a dummy leg. It is designed for 1/16″ vertical travel and 1/8″ horizontal travel for an oil refinery in Algeria.Read More
The slide plate assemblies are fabricated from stainless steel, phosphorus bronze, and carbon steel. The 2″ thick carbon steel base plate is securely anchored to a concrete foundation, and the stainless steel slide plates are affixed to the base plate by countersunk attachment bolts. The phosphorus bronze slide plates, with machined grooves on the underside are placed on top of the stainless steel plates.
To allow for lubrication between to the contact surfaces of the two slide plates, grease is added through a fitting on the side of the bronze slide plate. The fitting allows access to a channel in the center of the bronze slide plate that leads to the grooves. A hole is located in the 2″ thick base plate to allow for grout to be poured through after installation.Read More
The slide plate assemblies were fabricated from a combination of stainless steel for the low-friction sliding surface and 2-3/4″ Marinite® insulation to isolate the higher temperatures. A fabric reinforced isolator pad was placed between the slide plate and the I-beam for vibration control. The slide plates were tested for both load and heat transfer and will be utilized in a chemical plant.Read More
The top sheet of graphite measures 1/2″ x 11 1/2″ x 115 1/2″. This particular design also includes a bottom sheet of graphite with the same dimensions, but only 1/4″ thick. Each individual graphite sheet is bonded to a hot dipped galvanized backing plate with a 1/2″ lip all around for full welding. In an application where the pipe has large amount of movement due to thermal expansion, slide plates can be utilized to eliminate friction between the pipe support and the supporting member. Graphite is used when the slide plate must function at high temperatures. These particular graphite slide plates are designed for 1000ºF.Read More
Piping Technology & Products, Inc. designed and manufactured PTFE, 25% glass filled, slide plates for cable trays located on a floating structure. The slide plates are used to reduce the friction between the cable trays and the structural steel it is resting on. These particular slide plates are bonded to stainless steel backing plates that are bolted to the structure.Read More
The Bronzphite® slide plates shown above are constructed from graphite and phosphorus bronze with dimensions ranging from 3″ x 3″ to 6″ x 36″. They are designed for up to 500ºF and a total travel of up to 30″.
In general, Bronzphite® is a self-lubricating bearing plate made of a high quality bronze with graphite filled grooves. The solid graphite inserts are arranged in various patterns and sizes to meet customer specifications. This type of slide plate is best suited for high loads, low velocity applications and in places where the use of oil or grease in undesirable or unfeasible.Read More
Piping Technology and Products, Inc. recently designed and fabricated more than 75 pipe shoe and Bronzphite® slide plate assemblies for an oil refinery in Texas. Each assembly consists of two pipe clamps, a base plate and a maintenance free Bronzphite® slide plate. The pipe shoes with sizes ranging from 18 to 24 are fabricated from A387 alloy steel. They are designed for 965°F and 2 of horizontal movement.
The 3 x 3 Bronzphite® (graphite impregnated bronze) slide plates are self-lubricating bearing plates made of a high quality bronze with graphite filled grooves. They are designed for heavy loads, low velocity applications, and for situations where the use of oil or grease is undesirable or unfeasible.Read More
PT&P designed and fabricated eighteen graphite slide plates for a refinery project in India. These plates are made of graphite sheets with thicknesses of 6mm and 12mm. The overall dimensions of the plates are 3/8″ x 19-11/16″ x 19-11/16″ and 3/8″ x 61″ x 61″. The plates will be tack welded on top of big ton spring supports in the refinery to minimize frictional effects.

These ½ x 7 x 12 Bronzphite® plates were bolted to a 2 ¾ x 11 x 16 backing plate with a 5mm recess. The recess allowed the Bronzphite® plates to be countersunk and bolted to the backing plates. The Bronzphite® plates were designed to withstand 14Mpa working compression and a maximum temperature of 230˚F.Read More
Piping Technology & Products, Inc. designed and manufactured PTFE, 25% glass filled, slide plates for a chemical plant in Port Arthur, Texas.
These slide plates are constructed of PTFE, 25% glass filled, bonded to stainless steel backing plates. The top plates range from 123 ¾ square inches to 481 ¾ square inches and the bottom plates range from 69 square inches to 616 square inches.
