Last month we spoke about the progress of the ASTM B117 hot salt fog test and the part it plays in providing some of the technical background to all that we say about Enviropeel's ability to prevent corrosion - and we presented the 4500 hour report last year for your information.
Still going strong at 7500 hours
Now we have removed another sample flange from the hot salt fog cabinet at 7500 hours and we couldn't be happier with the result.
As you can see in the photograph, there is a marked deterioration in the control flange but the only difference that is visible between the six month and the nine month Enviropeel protected flanges is an increase in corrosion outside the protected area, on the sealing cap that prevents the corrosion that would occur if the pipe end was left open.
