Bronzphite® Plates for a Construction Company in Dubai

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.

PT&P Custom Designs and Fabricates Big Ton Springs Equipped with Lifting Lugs

Big Ton Springs

Big Ton Springs

Piping Technology & Products, Inc. specially designed and fabricated big ton springs equipped with side lifting lugs to support piping of a 102-megawatt, refinery co-generation power plant in California.

Under typical circumstances, this type of job application would utilize variable spring hangers, but because of the restricted space, the hangers’ size would be too small to support a hot load of 19,068 lbs and cold load of 17,212 lbs.  In order to satisfy both the required loads and space, PT&P engineers designed and fabricated figure 500 big ton springs equipped with side lifting lugs. The lifting lugs were attached to allow the big ton to suspend as a variable spring would in the field.

The big ton springs are comprised of A-36 carbon steel and built at 13″x 23″x 9-1/2″ with a downward travel of .232″. The job was completed within two days to meet the customer’s quick turn requirements.

Introducing PT&P’s Maintenance Free Slide Plates, Bronzphites®

Piping Technology and Products is a supplier of maintenance free slide bearing plates, Bronzphite®, whose high strength bearings and impregnated graphite, together create a concoction ideal for maintaining excellent wear resistance and durability under severe operating conditions. PT&P has supplied Bronzphite® for a number of companies in the oil, gas and power industry.

PTFE, 25% Glass Filled, Cut and Bonded to a Polyslinger

PTFE, 25% Glass Filled, Cut and Bonded to a Polyslinger

PTFE, 25% Glass Filled, Cut and Bonded to a Polyslinger

Piping Technology & Products, Inc. cut and bonded a PTFE, 25% glass filled, ring (see fig.1) to a polyslinger which will be utilized at a Chemical plant in Texas.

The polyslinger was a total weight of 33 lbs and its lip measured at 26″ O.D. The PT&P worker cut the PTFE, 25% glass filled, at 24″ I.D. with a thickness of 3/32″ and then bonded it to the lip of the polyslinger with an epoxy resin adhesive. PTFE, 25% glass filled, is used as padding, intended for reducing metal-to-metal friction.

Are polyslingers a necessity for you? Get pricing on one today!

How to Size a Spring Hanger

Piping systems are used to transport gases, liquids and suspended solids between units of a plant. The temperatures of the contents and the pipe when the plant is in operation are often quite different from the ambient temperature of the surroundings. The heat transferred during changes in temperature causes metal pipe to expand and contract. Piping designers must provide for movement due to temperature changes and forces caused by pumps, gravity and other elements of the piping system.Read PT&P’s “How to Size a Spring Hanger” Technical Bulletin for more information.

PT&P Specially Designs and Fabricates Constants for a Radiant-Tube Support System
Constant Springs

These constants are an essential component of the radiant-tube support system for a reforming furnace. Piping Technology custom designed these units to fit in the limited space available inside the furnace. The bolting patterns for the constants needed to be flexible enough that they could be attached to the supporting structure with any of the support system designs being considered.

Slide Plates: The “Sandwich” Concept
Piping Technology & Products, Inc. uses the “sandwich” concept when applying slide plates to our customers ‘ systems. Figure 1 shows a “sandwich” composed of two identical slide plates, one on top and another on the bottom. Each slide plate (which is like the bun of the “sandwich”) and a low coefficient of friction material which is bonded to the metal backing plate.

Slide Plates

Figure 1

Figure 1
In a typical application a slide bearing plate is welded to a structural steel member which is strong enough to provide the required support, but whose coefficient of friction is too high.

Slide Plate

Figure 2

Figure 2 shows an application in which a slide bearing plate is welded on top of one steel beam supporting the other beam. When the top beam moves (due to thermal expansion, for example) it slides across the surface of the bearing plate without contacting the supporting another beam. To return to our “sandwich” metaphor, the top half of the “sandwich” is bonded to the sliding beam, and to the bottom half to the supporting beam.
