Chemical technique
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 rings
- Glass angle
- Glass reducing piece with plastic clamping ring
- Glass intermediate piece with 2 plastic clamping rings
- Stainless steel angle with 3 stainless steel clamping rings
- 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
Plastic clamping rings in glass pipe systems
- Clamping ring FL-Optimal KE
ISO-K clamping screws etc. for high vacuum strength with large flange diameters
The section diagram of a vacuum pump shows from bottom to top clamping flanges ISO-K with screws, outlets with small flanges KF with clamping ring, butterfly valve bolted with clamping flanges, clamping flange, small flange pipe connections.
