Engraved Device Covers

Engraved Device Covers


     Joint Specialists is pleased to announce we are now able to offer Custom Engraving Products and Custom Engraving Services.  These engraved device covers have typically been a real challenge in the marketplace.  High prices, slow turnarounds and poor customer service have been (unfortunately) the primary industry standards for this space, and JSI is now dipping our toes into the water.

     Committed to shipping orders complete within 24 hours after receipt of an order (often same day), JSI is ready to take this headache off of your plate.  In addition to engraved device covers, we are offering engraved switch plates and other basic markers.  These are often used in HVAC systems, Hospitals, Schools, Data Centers and electrical applications (including cathodic protection systems and dozens of other applications).  There could be rare situations where we are only able to get a partial shipment out within 24 hours.  

     Device covers and switch plates are available in just about any size from a 1/2" x 1/2" plate to a 24" x 12" plate.  In addition, we are able to offer any number of different color schemes in terms of both the plate and the lettering.  

     So the next time you need metal and plastic name plates for your electrical and industrial usage -- keep us in mind and give us an opportunity to quote you.  I'm certain you'll be pleased with our pricing, service and delivery.

ScarGuard Abrasion Resistant Overcoat (ARO)

 Scarguard Abrasion Resistant Overcoat

ScarGuard adding an ARO to a length of pipe

     ScarGuard is a composite fiberglass fabric material that has been pre-impregnated with a high performance flexible resin.  This resin is activated by water and offer a very fast cure time once that water has been introduce.  When fully installed (and cured) ScarGuard offers a pipeline excellent abrasion resistance on top of factory or field applied coatings.  Many end users are requesting their entire line be coated with ScarGuard prior to directional drilling and road bore applications.

     It is important to note:  ScarGuard is not a stand alone "coating" it is simply added physical protection for plant and field applied coatings of all varieties.  

     ScarGuard is excellent at protecting your pipe from gouges and other coating damage during a pull through.  The material is very tough and has excellent abrasion resistance.

Installation of Powercrete R65/F1

Powercrete R65 is a 100% solids epoxy coating used for corrosion and abrasion protection on clean, bare steel surfaces and adjacent coatings. Here is a summary of the installation process based on the provided data sheet:

  1. Scope: Powercrete R65 is applied over clean, bare steel and adjacent coatings. It comes in a pre-measured kit with two parts: Part A (base) and Part B (curing agent).

  2. Surface Preparation: Clean the surfaces using Acetone, MEK, or a suitable solvent to remove grease, oil, salts, and contaminants. Abrade the surfaces by abrasive blasting to achieve a near-white ISO Sa 2½ or white ISO Sa 3 surface profile. Sweep blast adjacent FBE coatings. Evaluate surface preparation using ASTM D 4417 Method C.

  3. Preparation of Adjacent Coating: Clean and abrade 50 mm (2 inches) on either side of the cutback (bare steel area) of the adjacent coating. Remove the gloss and obtain a minimum of 2 mils (50 μm) angular profile.

  4. Preheating (optional): Preheating the cutback area can accelerate curing and eliminate moisture. Preheat the cutback area to approximately 40°C (104°F) to eliminate condensation or up to a maximum of 60°C (140°F) to accelerate curing.

  5. Mixing: Warm parts A and B to a minimum of 20°C (68°F). Pour all of part B into part A and mix thoroughly using a slow mixing paddle for 2 to 3 minutes. Avoid introducing air into the mixture.

  6. Application: Ensure that the ambient temperature is above 10°C (50°F) and the dew point is above 3°C (5°F). Slowly pour the mixed epoxy onto the pipe. Use trowels, brush, or a roller to apply the required minimum thickness of the coating to the field joint, covering at least 50 mm (2 inches) of the adjacent coating. Tape may be applied to create a straight edge.

  7. Dry Film Thickness: The recommended dry film thickness for a single coat is 20 mils (500 μm).

  8. Curing Times: The curing rate and drying times vary based on pipe and ambient application temperature. Refer to the curing rate chart provided in the data sheet for Powercrete R65/F1 to determine when to perform a Shore D check.

  9. Storage: Store Powercrete epoxy products in a dry, well-ventilated area in their original sealed packaging. Avoid exposure to adverse environmental conditions.
