Chain knockers with hardened chains promise a long service life. Their specially hardened chains are particularly abrasion-resistant, so that they do not wear out as quickly as sanitary chains in case of hard blockages. The chain knocker with hardened chains are therefore particularly suitable for hard incrustations on the pipe walls. In smooth pipes such as cast iron or GRP pipes, smooth chains should always be used, while in pipes with rougher surfaces such as stoneware and concrete pipes, but also in hard steel pipes, hardened chains with cams are the better choice.
