Press connector fittings made of non-alloy steel for high-temperature steel pipe heating applications

Jump to:
+44 (0)204 582 6495 Website

Application

Intended for use in industrial applications for thick-walled steel pipes, as a replacement for welded, threaded and rolled-groove connections in new installations and repairs such as:


  • Closed heating and cooling circuits.
  • Sprinkler systems.
  • Fire extinguishing systems.
  • Compressed air systems.
  • Systems for technical gases.


Not suitable for drinking water installations or combustible gases. The connectors may only be pressed with Megapress press rings and jaws.

Description

Press connector fittings with connectors made from non-alloy steel, grade 1.0308, for seamless, welded, galvanized and powder-coated black steel pipes, which have been industrially painted in accordance with DIN EN 10255, DIN EN 10220/ 10216-1 or DIN 10220/ 10217-1.


Sealing element:

A cutting ring, 1.4301 (304) grade stainless steel separator ring and an FKM profile in matt black are included in the bead of the press connector. The cutting ring cuts into the pipe during pressing and ensures a force-locked connection.


The fluoroelastomer (FKM) sealing elements are factory-fitted to the press connectors with increased cross-section to ensure that pipe surfaces with slightly uneven surfaces are sealed off.


During insertion of the pipe, and later during the pressing, the separator ring protects the sealing element from damage.


Press connectors:

The press connectors are equipped with the Viega SC-Contur, which is a safety technology certified by the German Technical and Scientific Association (DVGW), and ensures that the connection is guaranteed to be leaking in an unpressed state. In this way, inadvertently unpressed connections are noticed immediately during a leakage test.


Features and benefits:

  • Protection against external corrosion due to the zinc-nickel coating.
  • Universal use. Presses thick-walled steel pipes (3/8 to 4 inches), irrespective of whether the pipe is seamless, welded, uncoated, galvanized or resin-varnished.
  • Wide range of fitting arrangements available.
  • SC-Contur leak path technology.
  • A white dot and black rectangle indicates that the product is not suitable for drinking water.
