Engineering and production at our facility in Spreitenbach

Your specialist for special requests

Torgen (Switzerland) GmbH in Spreitenbach is able to respond at short notice to requests concerning all types of flexible connections.

With its welders qualified, the company, which has been established for more than 20 years, is qualified to connect metal hose connections and metal bellows with standard connections, e.g. Mapress, 3-part screw connections, nozzles, as well as with special parts supplied by the customer.

In our own production, with black/white separation, your special requests become possible through TIG/TIG round fine welding technology.

In addition to competent advice, our customer-oriented service also includes 3D designs. Design, calculation proofs (EN10380, EJMA 9) are part of our core competence. Leak tests with helium and pressure tests are a matter of course. This means that high vacuum up to 1000 bar can be tested internally.

Future-oriented

“Many innovative ideas are turned into successful and marketable solutions together with the customer”.

Efficient and future-oriented cooperation ensures advantages for all sides

👉 EJMA is the international standard for safe, durable, and system-critical piping systems.
Anyone who prioritizes operational safety and regulatory compliance cannot do without EJMA.

EJMA (Expansion Joint Manufacturers Association) is the globally recognized standard for metal expansion joints and the central basis for piping system planning, design, and calculation.

Using EJMA, engineers can ensure that metal expansion joints reliably accommodate thermal expansion, pressure variations, temperature changes, and cyclic loads, and perform safely throughout the entire service life of the installation.

Benefits of EJMA-Compliant Design

  • Safe and accurate design and calculation of metal expansion joints
  • Fatigue life calculation based on load cycles and stresses
  • Operational safety and compliance with standards guaranteed
  • Prevention of material fatigue, leakage, and piping failures

Applications

EJMA is applied worldwide in system-critical piping systems, including:

  • Power plants and nuclear facilities
  • District heating and district cooling networks
  • Industrial and chemical plants
  • Data centers
  • Research and high-tech facilities

Why EJMA Matters

Without EJMA-compliant design, piping systems may fail, leading to plant downtime, high repair costs, and safety risks.
EJMA is the international standard that ensures safe, durable, and code-compliant piping systems.
