Coating
We offer an array of options for coating pipe bends. We supply holiday-free polyethylene (YJ and UB) coated pipe bends as well as several types of post-bend spray-on coating, both external and internal. Compass Bending also provides tape wrap, shrink sleeves and polyurethane foam insulation. Insulated bends can be provided with tape, shrink sleeves or hardshell (spray-on polyurea) as the outside layer. We can supply coating materials and patch kits to ship to site for repairs and for covering field joints.

Notes
- Prior to coating, pipe bends are prepared with sand blasting to SSPC-SP6 or SSPC-SP10 depending on coating requirements.
- Appropriate primers are applied as required (e.g. prior to tape wrap).
- All coated bends (including YJ and UB pipe) are patched if necessary and holiday tested before shipping.
- We will bend Perma-Pipe Ultrabond IIISE (UB IIISE) only by special request with a waiver.
- YJ1 and UBRA coated bends are patched with K60 shrink sleeves. YJ2K and UB IIISE coated bends are patched with GTS-PE shrink sleeves. We can also use Stopaq wrapping products for patching when required.
- We can supply shrink sleeves and epoxy patch kits for site repairs and field joints.
- We can supply insulation half-shells, shrink sleeves, and tape wrap to be shipped loose to site for field installation.
- We keep the coating manufacturers’ spec sheets on file as well as installation guides, general information, and MSDS sheets. Call us for copies.
- All coatings applied by us come with quality assurance inspection reports.
- Canusa GTS-80 shrink sleeves have been discontinued, replaced with GTS-PE.
