What is a slide plate?
Added on Wed, Nov 3, 2010
A slide plate is a component that can be fabricated from a variety of materials including graphite, PTFE, 25% glass filled, stainless steel, and bronzphite. The purpose of slide plates is to produce a low-coefficient of friction between a... Read More
What is the use of a slide plate?
Added on Wed, Dec 1, 2010
The purpose of slide plates is to produce a low-coefficient of friction between a stationary support element and the moving pipe support component to reduce the forces generated as a result of pipe deflections during operation. Slide Plates... Read More
How do you install slide plates?
Added on Wed, Dec 1, 2010
For PTFE, 25% Glass Filled Slide Plates: Prior to Welding: Locate the slide plate base in the appropriate position on the existing steel surface. Place a protective covering on the PTFE, 25% glass filled. Where seal welding is not required, follow... Read More
When do I use a slide plate with a pipe shoe?
Added on Wed, Mar 23, 2011
Slide plates are primarily utilized on pipe shoes whenever axial and/or lateral movement is present and the frictional forces must be reduced. Bolted Clamp Pipe Shoe with Slide Plates Read More
How is PTFE used below the pipe saddle?
Added on Thu, Jun 16, 2011
The PTFE is generally used as a slide plate either affixed to the supporting steel or the bottom of the pipe saddle. This PTFE component acts to provide a low coefficient of friction between the saddle and the supporting steel. Stainless Steel... Read More
When do you provide sliding bearings for steel beams?
Added on Wed, Jun 22, 2011
Slide bearings are provided to decrease excessive friction forces that would be generated with direct steel to steel contact. Structural Steel Components with PTFE, 25% Glass Filled Slide Plates Read More
Why are slide plates sometimes required in a piping system?
Added on Thu, Feb 17, 2011
Slide plates are sometimes required when there is any movement at the pipe support location which would generate unacceptable friction loads. Graphite Slide Plates Read More
How high of a temperature can we use graphite slide plates?
Added on Thu, Jun 16, 2011
The bolted design graphite slide plates can be used in temperatures up to 1,000°F normal atmospheric conditions. Graphite Slide Plates Read More
What are reasons why the PTFE or Graphite pads peel off the backing plates?
Added on Thu, Nov 3, 2011
In the majority of cases, bond between the material and its backing plate would become degraded in the presence of high temperatures. With PTFE, if the heat reaches to 350˚ F, the glue becomes weaker. For Graphite Slide Plates, the maximum... Read More
For applications above 400 degrees F, what material is recommended for slide plates?
Added on Thu, Nov 10, 2011
Graphite material is recommended for temperatures higher than 400 degrees F for slide plates. Graphite Slide Plates Read More
Are there improper ways to install PTFE slide plates that would cause them to debond, degrade, or crunch?
Added on Thu, Nov 3, 2011
When seal welding the backing plate, the heat can cause this problem. PTFE Slide Plates Read More
How long are each of the slide plate elements designed to last for and do they require much maintenance and replacement?
Added on Thu, Nov 3, 2011
Slide plates are designed to last 20-30 years, you just need to ensure that the sliding surfaces remain clear of debris. Stainless Steel Slide Plates Read More
Does an increase in load generate a reduction in the friction coefficient in PTFE?
Added on Thu, Nov 3, 2011
Yes, with the increase of load, it takes less axial force to overcome the force of friction of PTFE. Variable Springs with PTFE Lined Pipe Stands Read More
What is the maximum temperature recommended for PTFE plates?
Added on Thu, Nov 10, 2011
The maximum recommended temperature is up to 400˚F. See the slide plate selection chart. PTFE Slide Plates Read More
Does weather, such as rain, snow, cold or heat have significant impact on corrosion or the friction coefficient of slide plates?
Added on Thu, Oct 27, 2011
For carbon steel backed PTFE slide plates, if they are exposed to excessive moisture can corrode if they are not galvanized or painted. However, if using stainless steel slide plates then weather is not an issue. Angled Pipe Shoes with PTFE Slide... Read More
Can PTFE slide plate material be used against PTFE or should it be used as PTFE to stainless?
Added on Thu, Nov 10, 2011
PTFE slide plate material can be used in both combinations. PTFE, 25% Glass Filled, Slide Plates Read More
What is the purpose of and benefit of using glass filled slide plates?
Added on Thu, Nov 3, 2011
Glass filled slide plates last longer than virgin PTFE. PTFE, 25% Glass Filled Slide Plates Read More
For offshore platform applications, do you recommend stainless steel base material for the sliding plate?
Added on Fri, Nov 25, 2011
Yes. We do recommend stainless steel slide plates over the galvanized material for it's longevity for the offshore application. Stainless Steel Slide Plate Read More
Is there a difference in thermal expansion rates between the slide plate and backing plate taken into account to prevent delaminating?
Added on Fri, Nov 25, 2011
Expansion rate between the slide plate and backing plate is not taken into account because the area of the slide plate is generally not large enough to experience any of these effects. PTFE, 25% Glass Filled Slide Plates Read More
Which slide plate material would you recommend for high cycle applications?
Added on Fri, Nov 25, 2011
We would recommend that you use the PTFE, 25% Glass Filled, slide plate if it is within the recommended temperature range (up to 400 degrees). PTFE, 25% Glass Filled Slide Plates Bonded to Stainless Steel Backing Plates Read More
How can we use slide plates effectively for steam lines?
Added on Fri, Nov 25, 2011
You would need to use the insulation type slide plate, ie: marinite, to insulate from the heat with PTFE on top of the structure to absorb the impact load if you have any steam hammers. Slide Plate Assemblies with 2 3/4" Marinite Blocks Read More
How do we decide whether to use the 7/16" or the 11/32" application of PTFE?
Added on Fri, Nov 25, 2011
The PTFE standard assembly is a PTFE to PTFE and 10 gauge backing plate combination which as a whole is 7/16" thick. Some customers require the 11/32" application of PTFE and this thickness can only be achieved when you utilize a stainless steel... Read More
Once installed, have you seen any problem with sand and grit getting onto the slide plates and causing problems?
Added on Fri, Nov 25, 2011
We have only seen this in applications when the upper slide plate is the same size as the lower slide plate. We recommend that the upper slide plate is larger than the lower plate in order to avoid this occurrence. As long as this bottom slide... Read More
In a cold climate where slide plates are used outdoors, is there a life span or other special things to consider?
Added on Fri, Nov 25, 2011
Consider the bottom surface is always covered by the top slide plate and is really never exposed to the elements. The life span should not be a consideration unless they are mechanically damaged. PTFE Slide Plate Installed in the Field Read More
