WATCH THIS TECHNOLOGY IN ACTION

Carl Hamm, the supplier of steel and customized piping components, and Esser Twin Pipes have cooperated to combine two of their respective premium products into a pipe system that is engineered for underground shaft construction or for laying pipelines through boreholes. The tight sleeve connection - ZSM - from Carl Hamm is an axially non-positive and detachable pipe connection. Due to the quick assembly/disassembly and space-saving design, the use of ZSM systems ensures considerable cost savings through the whole lifecycle. The patent-protected tight sleeve system is successfully used internationally in a wide range of installation applications in the mining industry. Previously, this connection was installed using unhardened steel pipes. In order to create an alternative to conventional piping systems, pipes from the ESSER TWIN 700 series were chosen. Their inner wear layer has a hardness of 63 HRC, which ensures high resistance to abrasive media. Compared to conventional pipe systems made of unhardened mild steel, ESSER TWIN PIPES offer greater cost- effectiveness due to reduced replacement and maintenance downtime. The combination of ZSM connection and ESSER TWIN PIPES is the optimum of durable pipelines and space-saving, tension-resistant connection geometry. It is widely applied in backfilling operations as well as for the transport of building materials. Both applications exert high pressure on the piping components due to the conveyed materials; excellent quality of system components is vital. ESSER is an experienced and reliable partner for any R&D project. We continuously work on the improvement of our products and have developed unique expertise in many markets and applications.
