Repairing Powercrete Coatings

 How Do You Repair Powercrete Pipe Coatings?

     When epoxies coated pipe is in the field being welded up; there is often going to be some amount of damage that has occurred at some point.  That could be during transit.  Pipe could get damaged one of the times it is moved.  Weld spatter can cause damage adjacent to a girth weld.  Equipment or crew members can cause damage accidentally as well.  When those things happen; fear not -- we have solutions. 

     So for starters, we are going to look at various options for making repairs to epoxy pipe coatings; whether that is FBE, DD or any of the other options that are out there today.  

MAJOR DAMAGE

     In a case where there is a large area of damage; it must all be re-coated.  Depending on how large the damaged area is; we'd be looking at:

• using a Powercrete R65/F1 1#, 2# or 4# kit to re-coat the area (after that area has been cleaned, etc)
• using a shrink sleeve to encapsulate the entire damaged area (after cleaning the pipe surface, etc).
• use Powercrete J in a 2# or 4# Kit
• use Powercrete R95 in a 2# or 4# Kit

MODERATE DAMAGE

     For moderate damage, you can actually use the very same methods

• using a Powercrete R65/F1 1#, 2# or 4# kit to re-coat the area (after that area has been cleaned, etc)
• using a shrink sleeve to encapsulate the entire damaged area (after cleaning the pipe surface, etc).
• use Powercrete J in a 2# or 4# Kit
• use Powercrete R95 in a 2# or 4# Kit

MINOR DAMAGE & PINHOLES

     For minor damage and pinholes, we would recommend you use Powercrete R65/F1 in 50ml repair cartridges.  A case of the repair cartridges includes:

• 25 each of the 50ml cartrdiges
• 50 each of the static mixing tips
• 1 each of the dispenser gun

Powercrete Repairs

Repairing Powercrete Coatings

     Repairing Powercrete products is a fairly simple proposition; not altogether different than the process of installing it in the first place.  In this case, I'm talking about repairing Powercrete J, Powercrete R65/F1 and Powercrete R95 products; though some of this would also apply to a Powercrete DD repair.

     In addition, there are cases where a Powercrete J (or R65 / F1 / R95) might be installed, but it it latter discovered that the required coating thickness was not reached (in one or more places) and an additional layer is needed in order to meet the spec.

     So in all of those cases, we must start over.  We must create an anchor pattern on top of the previously installed Powercrete product (J / R65 / F1 / R95).  That anchor pattern can be achieved using a brush blast - or it can be achieved using 60 or 80 grit sandpaper.  Then the pipe can be lightly preheated and more epoxy applied.

     We would want that anchor pattern to on every bit of surface area where the Powercrete will be applied.

     In terms of what Powercrete product could be used there are a few options:

- Powercrete R65/F1 is available in 50ml cartridges specifically designed for minor repairs.  A case of R65/F1 50ml cartridges contains 25 cartridges, 50 static mixing tips and 1 dispenser gun. 

- Powercrete R95 50ml cartridges are also available.  These are sold in cases of 12 cartridges, 24 static mixing tips and 1 dispenser gun

- Powercrete R65/F1 1# Kits are the perfect size for making repairs.  Just like a 2# or 4# kit; but smaller. 

- Beyond all of that; we see folks use Powercrete J in 2# kits (or Powercrete R65/F1 and R95) in 2# kits used as repairs.  It all depends on what the spec you are working from requires.
