CHROME CARBIDES
Chrome carbide collars are made for the SK/metric connection system. The outer part of the collar is made of S355 (ST52) steel while the inner part in steel alloy and chromium carbides to ensure high resistance to abrasion. Mainly used for the production of double wall pipelines and in particularly critical points of the pipeline.
