Rubber Steel Ring Gaskets


Rubber steel  Ring gaskets  have  a very specific and focussed  application range in the field of Gaskets - Wherever safe sealing of media with an extremely low leakage rates and low joint loads  at relatively low temperatures is required, Rubber-steel Ring gaskets provide the best possible solution.

The different steel supporting rings provide increasing pressure stability and helps easy handling of the Rubber- steel Ring gaskets - even under the complex assembly conditions.

With Rubber providing an excellent adaptability to the sealing surfaces even in the most difficult service conditions, a safe sealing is ensured.

We can do the selection & design the best possible Rubber-steel Ring gasket for your operating conditions.  

Benefits :

 

• Need of Minimum Torque
• Not necessary to retorque.
• Used with mis-matched or misaligned flanges as the pressure is dispersed evenly
because of  flexibility of Gasket Material
• With Rubber providing Excellent Resilience , Perfect seal  is assured irrespective of  fluctuating pressures and temperatures.
• Wide Range of Rubbers are available to suit any application.

 

Applications :

• Pipelines for water, gas, sewage, oil and chemicals.
• For enamel coated flanges.
• Plastic flanges
• For Mining
 Industry

 

Rubber-Steel Ring Gasket : Profile STG
Profile STG

STG profile Rubber-steel Ring gasket consists of a carbon steel ring which is completely enclosed in Rubber. Thus the steel ring is protected against corrosion and media. As a result of the vulcanisation high adhesion is guaranteed between the Rubber and the steel ring.

 Salient features:

  • Offers excellent reliability against pressing or pushing out because of the steel reinforcement
  • Simple, safe and cost-effective gasket assembly compared with non-reinforced Rubber gaskets due to the dimensional stability
  • Extremely low leakage rate as a result of the homogenous Rubber coating, therefore particularly suitable for pipeline systems with environmentally endangering media
  • Low demands made on the flange surfaces due to the soft, adaptable sealing surface, sealing is even possible with slightly damaged flanges
  • Depending on diameter usable up to approx. 25 bar with a tightening surface pressure of 2 N/mm2 up to max. 15 N/mm2

 

                                                
Typical applications:

 

Gas and drinking water supplies

Chemical industry - both with aggressive and environ mentally endangering media

Flue gas purification plants and cooling circuits in power plants

Sewage networks
 
Pipeline construction with vacuum-operated pipelines as well as pipeline systems with fully Rubberised or enamelled  flange sealing surfaces

Enamelled pipeline and apparatus flange connection

 

Rubber-Steel Gasket PROFILE STG2


Profile STG2

 

The STG2 profile Rubber-steel gasket is a further development of the STG profile Rubber-steel gasket. On the inner diameter it has two stable sealing lips and on the outer diameter the shape of the WG profile Rubber-steel gasket.

Salient features:

 

  • Reliable tightness even with the slightest fastening torque, therefore the STG2 profile Rubber-steel gasket is particularly suitable for flanged joints made of plastics, to which high forces should not apply
  • Greater tightness as a result of the self-sealing effect of profile STG2 the sealing lips with internal pressure load
  • No overstressing or creeping of the flexible sealing lips compared to Rubber-steel gaskets with solid profile extension such as an O-ring or tapered ring
  • Optimal compensation of flange irregularities as a result of the flexible sealing lips, particularly if all-over sealing cannot always be guaranteed as with glass-fibre reinforced flanges
  • Certain compensation of smaller flange distortions
  • Depending on diameter usable up to approx. 25 bar with a tightening surface pressure of 2 N/mm2 up to max.  15 N/mm2

 

Typical applications:

 

Plastic and glass-fibre reinforced flange joints    
Sealing vacuum-operated pipeline systems in the chemical industry
Gas and drinking water supplies
Sealing torsionally soft flanges

 

 

 

 

Rubber Steel Gasket PROFILE STS


Profile STS

The STS profile Rubber-steel gasket consists of a centring,
 supporting ring and a sealing ring made of Rubber with
 integrally moulded sealing lips. The centring supporting
 ring is available in stainless steel or
 plastic.

 

Salient Features:

 

Trouble-free replacement of the Rubber sealing ring – as
 a result the WS profile Rubber-steel gasket can be used
 repeatedly

Safe use and good handling of the sealing material
 Rubber - even for large nominal diameters

High impermeability as a result of the self-sealing effect
 of the sealing lips with internal pressure load, the internal pressure widens the sealing lips and is primarily

conducive towards impermeability

Manufacturing of special dimensions without any
 additional tooling costs, for an inner diameter of approx. 400 mm and up

Depending on diameter usable up to approx.
 25 bar with a tightening surface pressure of
 2 N/mm2 up to max. 15 N/mm2

 

Typical applications:

 

Sealing of tank flange connections

Sealing of special flanges

Sealing of cooling and condensate pipelines in power

 

 

 

 

 

 

Rubber Steel Gasket PROFILE STL



Profile STL

 

The STL profile Rubber-steel gasket consists of a bichrome plated St37 supporting ring and a Rubber sealing ring with
 integrally moulded sealing lips. The supporting ring is also
 available in stainless steel or plastic.

 

In contrast to conventional gaskets the Rubber sealing ring of
 the STL profile Rubber-steel gasket is in the off-load. This
 means that the supporting ring absorbs all the forces which
 are too high for the Rubber sealing ring. A further advantage
 is that the Rubber sealing ring is shut up on the outside by
 the supporting ring. As a result of the sealing in the off-load
 both very high internal pressures and additional forces from
 the pipeline system are allowed. The WL profile Rubber-steel

gasket combines the advantages of a Rubber gasket with
 those of a
metal gasket.

 

Salient Features:

 

No overloading of the Rubber sealing ring is possible if
                                                               pipes are installed vertically

Reliable sealing even with strong pressure cycles or
 shocks

Simple and safe assembly, assembly faults due to
 applying too high and varying tightening torque will be
 minimised (most frequent reason for the failure of a
 Rubber-steel gasket

Trouble-free replacement of the Rubber sealing ring,
 therfore reusable
 

Advantages as a result of the flexible sealing lip, as
 aleady explained with the STS profile Rubber-steel gasket

 

Manufacture of special dimensions without any additional tooling costs, for an inner diameter of approx.
  400 mm and up
 

Very large application range, depending on diameter
  usable up to approx. 100 bar with a tightening surface
 pressure of 12 N/mm2 up to max. 250 N/mm2 with a
 supporting ring made of steel

 

Applications :

High-pressure pipelines, e.g. gas pipelines for gas
  supplies, gas pressure regulator systems

 

Pipeline construction, e.g. underground pipelines

 

Flue gas purification plants and cooling circuits in power
 plants

 

Pipeline and appliance construction with partially Rubberised flange sealing surfaces
