Inspection of the scraping result

Inspect the scraping result, i.e. the swarf must be completely removed and the
markings applied before with the FRIALEN marker may no longer be visible.
For bundled coil pipes control the scraping result with regard to the swarf
thickness or remained marks on the pipe very carefully.
The blade (2) is adjusted for a swarf thickness of 0,3 – 0,4 mm (approx. 0.0118
– 0.0157 inches). For the scraping of FRIALEN safety fittings the wear limit is
max. 0,5 mm (approx. 0.0197 inches) and must not be exceeded. Please note
differing requirements of other fitting manufacturers.
If the marker lines are not completely removed, the scraping process should
be repeated.
An abrasion of the blade can enlarge the swarf thickness inadmissibly. This
abrasion occurs because of multiple usage and outside influences (sand, soil
etc.). Therefore the strength of the swarf must be measured regularly - e.g.
with a calliper gauge. Scraper blades are worn parts and have to be replaced
(see chapter 8).
NOTICE
An incomplete scraping or a differing swarf thickness may result in a leaking
fusion joint.
