AUTOBond: (Fusion Bond Epoxy)

The AutoBond™ Fusion Bond Epoxy (FBE) Joint Coating System is an automated field joint coating system that provides quick and precise FBE application. Using custom software and assisted by a specially designed application head, we can accurately customize the applied film thickness as per the specific requirements of each job. Fusion Bond Epoxy (FBE) has become a trusted solution for infrastructure projects in the harshest environments in the world. Now, the AutoBond™ makes it possible to provide that same level of superior corrosion protection to the field joint with quick and easy application


  • Reduces environmental footprint
  • Minimizes worker exposure to harmful materials
  • Consistent film thickness across entire joint area
  • Fewer repairs than manual application; superior corrosion protection
  • Consistently achieves productivity targets

Liquid Epoxy:

KEYMAYprovides specialty coating services for major pipeline and facility projects in Canada. We comply with or exceed all CSA Z245.30 standards for surface preparation, induction heating, coating application, and in-field quality control inspection. The key advantages in engaging KEYMAY as a Subcontractor include: first-rate performance record in pipeline coating, technological advantages, HSE excellence, and reduction in financial, environmental and project risks.

Liquid epoxy’s can be applied using brush, roller or spray applications.

Foam Insulation:

KEYMAY provides an injection moulded spray foam insulation system that provides continuity of insulation between the factory applied coating and the field joint. This system uses a polyurethane foam designed to provide exceptional thermal qualities for pipelines that operate at higher temperatures. Combined with a liquid epoxy and a heat shrink sleeve, KEYMAY ties the field joint to the mainline coating for continuous protection against heat loss and corrosion.

2 & 3 Layer HDPE Shrink Sleeves:(No pictures yet)

Shrink Sleeves offer superior corrosion protection for pipelines using a tubular or wrap around sleeve that is applied in the field on the girth weld. Shrink sleeves are highly resistant to mineral acids, they are tough but at the same time flexible and resistant to vibration and movement of the pipe.

2-layer systems are a sleeve that consists of an outer layer made of polyolefin which are usually polyethylene (PE) or polypropylene (PP) and a layer of heat activated adhesive. These can be installed on all pipe sizes that consist of PE, PP or Fusion Bond Epoxy (FBE) coated pipelines.

3-layer systems, are like 2-layer in which they have an outer layer of polyolefin and a heat activated adhesive, but in this application, they require a third layer which consists of a two-part epoxy primer which is applied prior to the sleeve being installed.

Shrink sleeves are popular today because of their ease of installation, excellent protection, and are cost effective.
