Wellhead And Pipeline Spray Foam Insulation

Application: Wellhead Insulation

spi-wellhead-headerTHE CHALLENGE:

Cold weather creates freeze-up of exposed piping. Loss or decreased flow is essentially lost revenue. There are two typical solutions, both of which are either costly or ineffective.

1) Methanol injection is costly. A secondary concern is the need for constant monitoring of the methanol to ensure levels are maintained.

2) Typical snakeskin/wrap insulation is inefficient due to the gaps and breakdown caused by weather and rodents. Wrap insulation becomes a home for rodents. Mice attract snakes and other predators, which are an obvious hazard (injuries, hantavirus) for workers, not to mention the further damage to equipment, wiring and the wrap.

SOLUTION:

Applying Spray Polyurethane Foam completely encapsulates piping while leaving all valves and controls exposed, allowing necessary access. Spray Polyurethane Foam has outstanding R-value which prevents freeze-up. Methanol consumption is thereby reduced or even eliminated. Mice, rodents, birds, etc are unable to penetrate this product, therefore reducing any associated hazards. The foam insulation remains intact allowing it to maintain a constant temperature. This allows for greater production; translating to increased profits!

PROCESS:

  • Piping is wrapped with poly film to allow for removal of insulation if necessary.
  • Sprayed Polyurethane Foam is applied to a thickness of 2-3?.
  • Excess foam is trimmed around all valves and controls.
  • A polyurea top-coat is applied to a thickness of 0.40-0.60?.

MATERIAL SPECS:

2 Pound Closed Cell Foam – Class 1 Flame Spread. R Value of 6.3 per inch applied. This closed-cell spray foam provides superior energy economy and durability while significantly reducing unmanaged moisture and air infiltration.

Polyurea Top Coat – Polyurea elastomer ideally suited for use on well-head insulation projects. It has excellent abrasion resistance, even at high temperatures; remains flexible at low temperatures; is highly resistant to impact over a wide temperature range; and is resistant to water and a wide range of chemicals.
