Foam insulation for field joints on insulated pipeline
I am involved in a project that involves a buried/submersed 12" pipeline that will be insulated. It has 4 one inch heat trace lines bonded to it for skin effect heating. The main body of the pipe is insulated in the coating plant. The field joints will be filled in the field using portable equipment in a truck. The field joint area will be cover with sheet metal that is temporarily banded around the area to be filled. As a coating consultant, we are seeing several issues with the foam application, but have little information about how to ensure the foam is being correctly installed. The applicator is not giving us any inspection parameters to ensure proper density, cure, temperatures, environmental conditions, pressures, ratios, etc. Where do we get this information? Are there industry standards that we can start with?Thanks, Richard Norsworthy 214-912-9072 |

Rich, There are many technical documents on the installation of closed cell SPF available to download for free at spray foam.org. In the field, you need to use a foam with the correct physical properties that can handle the climate you are spraying, Also would need to know what temperature the heat trace lines are. Most SPF can handle around 190 degrees F without scorching. Feel free to call to discuss 571-239-5221 |
