FLEXTRON:
ELECTRO-
POLISHED
CORRUGATED
HOSES

The flexible solution with the purity of ultron

Flextron from Dockweiler is manufactured from mechanically corrugated stainless steel tubes. High-quality stan-dard material is stainless steel 1.4404. A stainless steel wire braiding is added for higher pressure resistance. The unique combination of electropolished surface and flexible corrugated hose minimizes the risk of contamination and enables gas transport under full UHP conditions throughout the system.

Advantages

Advantages of Dockweiler stainless steel corrugated hoses at a glance:

Highest purity requirements – from the gas tank to the production facilities
Fast and flexible connection of system components
Particle generation is reduced to a minimum
Smoothed surface minimizes the required flushing and evacuation time
homogeneous passive layer for optimum corrosion protection
A wide variety of connection ends allow installation into the overall system
Tightness guaranteed as with a weld seam: with ZeroCon connection
Oscillations and/or vibrations in the system can be decoupled with Flextron
Optimal for compensating installation tolerances as well as narrow dimensions

General Fields of Application

Dockweiler Flextron was developed for use in the semiconductor industry and fine chemistry. In these industries, the highest demands are placed on the purity of the process media. Only Flextron's electropolished surface makes it possible to meet these requirements right down to the last point of the supply system:

Process gas supply
Mechanical decoupling of machines and plant components
Sets new standards in UHP media systems
