Unzertrennliche Verbindungen
Die zugfeste Steckmuffen Verbindung
Die zugfeste Steckmuffenverbindung – kurz ZSM – gehört zu den längskraftschlüssigen und lösbaren Rohrverbindungen. Sie wird in Schachtleitungen im Untertagebergbau und im Tiefbrunnenbau eingesetzt.
Unser patentgeschütztes Steckmuffensystem stellt aufgrund der schnellen und einfachen Montage/Demontage, des minimierten Platzbedarfs sowie des günstigen Preises eine interessante Alternative zu anderen gängigen Verbindungssystemen dar.
The Tensile-Resistant Socket Joint
The ZSM (short for Zugfeste Steckmuffenverbindung, German for “tensile-resistant socket joint”) is a positive-locking and detachable pipe connection. It is used in shaft pipelines for underground mining and deep well construction.
Our patented socket system is an attractive alternative to conventional connection systems due to its quick and easy assembly/disassembly, minimal space requirements, and cost-effectiveness.
The Success Story of ZSM
The ZSM connection (Zugfeste Steckmuffenverbindung) was introduced in 1992 as a simple, fast, and leak-tight joint, initially used in well construction. During the 1990s, its potential was recognized, and it was further developed in cooperation with Rheinbraun (now RWE Power). This innovation revolutionized Rheinbraun’s well operations, leading to the exclusive use of ZSM piping in all their wells.
In 2003, the first riser pipe in the German hard coal mining industry was installed with ZSM technology at the Heinrich Shaft in Essen. Since then, the ZSM connection has been continuously refined and successfully applied in a variety of international installations.
ZSM
Reliable and Detachable Pipe Connections for Various Applications
Safe solutions for a wide range of piping systems.
- Pressure Pipes
For pipelines transporting liquids under pressure, this system provides tight and secure connections—even under high-pressure conditions. - Casing Pipes
Used for lining boreholes in well drilling; they offer strong and stable support to maintain structural integrity. - Filter Pipes
Designed for filter systems, they provide leak-tight connections to ensure the effectiveness of the filtration process. - Non-Pressurized Pipes
For pipes that do not carry pressurized liquids, this system offers reliable connections that are easy to assemble and disassemble.
Fields of Application
ZSM connections are versatile and used across numerous industries and applications.
- Underground Mining
