Delivery Programme

The pipe connection systems, fittings
and special designs according to customer specifications or drawings for plant construction of the family company LINNEMANN GmbH, have many advantages.

These become evident above all by the extensive range of material alternatives, etc. so that many application requirements can be met. It is extremely helpful for the designer
to have access to a wide range of components from one provider. The design and material variety can be demonstrated by the main components of pipe connections:
Different demands are made depending on the system beginning with the flange material. Glass is used where process transparency is demanded, approvals for foodstuffs prescribe high grade steel. Aluminium is the lower costs alternative:
- high grade steel flanges
- glass flanges/glass blind flanges
- aluminium flanges

The connection determines the design:
- Welding flanges
- Clamp flanges
- Screw-in flanges

Transitions partly with different standards or cross-sections demand
- Adapter piece
- Intermediate piece
- Reducing piece
Gaskets must be provided according to the adapter systems, pressure conditions or temperatures:

- NBR gaskets
- FKM gaskets
- EPDM gaskets
- VMQ gaskets
- PTFE gaskets
- Silikon gaskets
- Viton gaskets
- Metal gaskets
- Stainless steel gaskets
- Elastomer O ringsFraunhofer IGB, Plasma technique and thin layers

- Glass intermediate piece with 2 plastic
  clamping rings
- Stainless steel angle with 3 stainless steel

- Glass/metal intermediate piece with a
  plastic clamping ring
- Stainless steel - flexible hose
And in addition to the handling and area of application, the material is also decisive in the choice of clamping rings:

Stainless steel clamping rings for pressure safety
- Clamping ring FL-Standard
- Clamping ring FL-Extra
- Clamping ring FL-Stabil
- Clamping ring FL-Stabil safety catch
- Clamping ring FL-Solid

Stainless steel clamping rings for vacuum
- Clamping ring FL-Compact 20 bar
- Clamping ring FL-Spezial
- Clamping ring FL-Optimal
  (also in aluminium)
- Clamping ring FL-Massiv
- Clamping chain FL-Ultra
- Quick release clamp FL Rekord
