Influence of quality


Spiral wound Gaskets SPV2J

• Construction: – Metal strip and soft material spiral wound. Inner supporting is necessary. Depending on the installation space an inner and/or outer ring is required.– Metal strip/inner ring: stainless steel, nickel etc., outer ring St galvanized – Filler of soft material: PTFE, graphite, mica– Structual shape: rings, oval, with sealing zone , with ribs

• Operative range: – pressure: up to 250 bar – Temperature: depends on material up to 500°C and higher– experienced in refineries, Chemical plants, pipeline engineering.

– Good sealing behaviour (TA-Luft suitable)


Spiral wound Gaskets

• Construction:Standard with sealing zone

• Dimensions:– DIN- and ANSI-flanges– all diameters up to 2000 mm

• Characteristic values:Spiral wound gasket layers of PTFE (u) Grafit (u) PTFE (k) Grafit (k)

Influence of quality

Dictance oft soft material to metal windings

Tolerance of thicknes of inner- and outer ring to avoid metal to metal contact

Number of metal windings

Number of soft windings

Number of welding points on metal windings

Loose inner- and outer ring to realize ability to adapt at surface

Detail marking


Why Kempchen?

• seamless outer ring up to 1500 mm diameter

• higher temperature stability because of usage of graphite foil with a purity level of minimum 99%

•high variety of material due to a comprehensive raw materials warehouse

• high flexibility because all necessary manufacturing technology is available (turning, winding)


Corrugated gaskets with layers

• Design: – corrugated metal ring, thickness 1, 3 mm, with layers bonded on both sides. Sheet thickness 0,5 mm.– material of supporting ring: 1.4541; 1.4571; 1.4828; 2.4066; 2.4360. and much else– layers: PTFE, graphite, mica, cord of glass fibre or mineral fibre– forms: rings, ovales, frames, also with division bars, holes and fish plates

W1A-3


Corrugated gaskets with layers

• Disadvantages: – assembling under vacuum– sensitive handling (diameter > 1000 mm)– contact in thread– not suitable for self-cutting

• Advantages:

- vacuum-sealed- safe pressed soft material- high form stability- high temperature stability- high chemical resistance- fulfills all established regulations- small diffusion section


Why Kempchen?

• traceable marking

• development together with Shell which is field-proven for many years

• safe and repeatable compound of layer and core by automation

• only usage of graphite foils with quality of 99%

• safe and repeatable corrugated pitches by presicion tools


Influence of structure


Core of Kammprofile


Kempchen

• Due to special manufacturing processes the grooved tops and valleys run exactly parallel

• automatic, safe, reproducible connections of core and layer

• high flexibility due to stockable raw material variety

• reliable service due to the fact that everything is made in own production

Agenda

Leakage rate

The specific leakage rate of a gasket depends on:

• Medium, presse and temperature

• Gasket type

• Sealing material

• Bolt force and surface pressure

• Quality of flange

•Installation – Method of screwing– real pressure of sealing surface


Reduce leakage to protect environmental

Use the best available techniques for permanently minimised fugitive emission

Philosophy


Comparison of leakage rate


Comparing in depence of leakage rate


Agenda

•Strategy






Task:Analysing surface


KemAnalysis is…

A procedure to analyse sealing surfaces to assess thesurface pressure distribution.

•Knowlegde about:- loss of bolt load during installation - deformation of flange

•Influence of:- uneven sealing surfaces on the sealing behaviour- damages on the sealing behaviour

•Determining:- necessary repairing measures- the best possible sealing configuration

Summary

Verifying the quality and performance of your gasket supplier

Choose the right gasket for your application in relationship with your supplier

Use original material from leading manufacturer
