ProTek Composite Wear Pads

APP’s ProTek Composite Wear Pads are designed to prevent metal-to-metal contact in steel piping systems.

APP’s ProTek Composite Wear Pads are in stock and designed to prevent metal-to-metal contact in piping systems. They effectively isolate the pipe from contact with I-Beams, guides or concrete supports. These areas are the most susceptible to corrosion and cost millions to repair and maintain. Our wear pads are the most cost effective solution to piping system corrosion.

Wear Pad Installation (pdf)
The wear pad can be installed before or after paint/coating is applied, during fabrication or in the field.
Wear Pad Manufacturing
The wear pad is manufactured to the exact outer diameter of the pipe for a precise fit and seal. The inside is pre-roughened ID to NACE 1 coating specification to provide anchor profile for epoxy.
Epoxy Adhesive (EX-100)
The epoxy system has 2,500 psi of shear strength and ensures an impermeable seal for the lifetime of the pipe. MSDS (pdf)

    ProTek Composite Wear Pads FAQs  See All FAQs »

    • Which products do you keep in stock?

      We carry our ProTek Wear Pads, ProTek Pipe Shoes and ProTek U-Bolt for standard pipe sizes. We also inventory metallic hardware for pipe support applications.

    • Which composite wear pads do you stock?

      Our goal is to make sure we can meet the demanding delivery times necessary to execute big and small projects in your industry. We keep 200-500 of each standard ProTek Composite Wear Pad size in-stock at all times so that we can help you get a major project started or fulfill the immediate needs of turnarounds.

    • What is your standard ProTek Composite Wear Pad size?

      Our ProTek Composite Wear Pad dimensions are available in the same dimensions used for metallic wear pads. This allows our composite wear pads to be a direct replacement on specifications and requires only minimal change to existing pipe system designs. Most ProTek Composite Wear Pads are:

      • Thickness: 1/4”, which requires only minimal changes to the BOP (Bottom of Pipe) dimension
      • Length: 12” or 14” long to allow for ease of installation and protection during expansion and contraction

      While the standard degrees of coverage were designed for pipe resting on an I-beam, actual degrees of coverage vary based on pipe size and application. However, the interaction between the pipe and I-beam is only a few degrees, and our standard is based on pipe size in order to cut down on material cost and help keep prices low.

    • How strong is your wear pad system?

      One of our clients approached us with issues encountered on a 36” line filled with crude that was sitting on a metal beam. They wanted to know if our composite material would be able to handle this load. They asked us to perform a compressive test to prove it could handle 26,000 pounds. We tested our standard (1/4” thick, 30 degree coverage, 12” long) wear pad on a 10” diameter 1” thick pipe. We had to stop the test at 54,000 pounds when the massive pipe began to ovalize. However, the wear pad remained intact! Because our composite material is flexible and not brittle, the point of contact with the steel grew as the pipe ovalized. Thus, as the pipe ovalized, the increased footprint of our wear pad allowed for even greater support.

    • How long does it take to install a composite wear pad?

      On average, a wear pad should take no more that five minutes to install using entry-level personnel. Our wear pad installation instructions are nine steps and one page long. Our two-part epoxy system is housed in a two-part cartridge that is placed in a two-part epoxy applicator and dispensed through a static mixing nozzle. Once again, we use this system to minimize the occurrence of human error. Most two-part epoxy systems use two containers and are mixed by hand using an exact mix ratio that can easily be mixed incorrectly. Our system is as easy as squeezing a caulking gun.

    • Can your composite pipe supports be installed on painted pipe?

      Yes, this is one of the key features of our composite pipe support system. Our epoxy system is compatible with any cured coating surface, though a word of caution: our epoxy will sometimes bond to the paint better than the paint does to the pipe. If shortcuts were taken during the coating process, our epoxy has been known to remove the coating from the pipe. If the coating is properly applied this will not be an issue. When using our ProTek Composite Pipe Shoes no preparation is necessary since they are banded to the pipe.

    • How does installation differ between composite pipe supports and metal pipe shoes?

      Composite pipe supports require no welding to install — our products are either epoxied or banded to the pipe so installation does not require a certified welder or hot permit and the pipe can be an active line. Composite pipe supports weigh a fraction of what metal pipe shoes do and typically, only one person is needed for install and there is no need for a forklift or other lifting assistance. Thanks to the above reasons, it takes far less time and effort to install composite pipe supports which will save your budget and the bandwidth of your installers.
