Rubber:

The Basic Elastomers:

Natural Rubber (NR):
The original

gum rubber

possesses several excellent mechanical properties. It has good tear and

abrasion resistance

, high resilience and good low temperature

flexibility

. Its use is limited in

gaskets

by very low chemical resistance (especially to solvents and oil which greatly reduce its strength), poor resistance to sunlight and ozone (which causes cracking) and the restricted temperature range.
Natural Rubber (NR): - Neoprene is the registered trade name of Du Pont.
The oldest of the bulk produced synthetics. More correctly referred to as

polychloroprene

. It is superior to NR and SBR in resistance to ozone, sunlight and weather. It also has a degree of resistance to attack by petrol, mineral oil and other light hydrocarbons and can be made flame resistant. It only has moderate low temperature flexibility and tends to suffer from poor compression set especially when hot.
Hypalon (CSM): - Hypalon is the registered trade name of Du Pont.
Chlorosulphonated

polyethylene

. Possesses excellent resistance to ozone and good resistance to flame, mineral oil, heat, weather and acid, making it ideal for use outdoors or near sparking electrical equipment.
Styrene Butadiene (SBR):
A synthetic equivalent to

natural rubber

. The two are usually compounded together to produce an elastomer with similar mechanical properties to NR but with better high temperature performance, flexibility and a slightly greater resistance to attack from animal and vegetable oils.
Nitrile (NBR):
A copolymer of butadiene and acrylonitrile. Especially resistant to mineral oils and aromatic and aliphatic hydrocarbons and alcohols - depending on the actual nitrile content of the elastomer. High and low temperature performance can be good. Oil resistance can be increased by compounding, at the expense of low temperature flexibility. Ozone, sunlight and weather resistance is poor.
Ethylene Propylene (EP):
Often supplied in a diene modified form (EPDM). It has good mechanical properties and is resistant to ageing, weathering, ozone, oxygen, steam and water. It is especially resistant to phosphate ester based hydraulic fluids but is not recommended for use with

petroleum oils

or fluids. Good resistance to mineral acids.
Butyl (IIR):
A copolymer of isoprene and isobutylene. Similar to EP in its ability to cope with phosphate ester based

hydraulic fluids

and

mineral oils

. It is highly impermeable to gas and moisture and has good general

chemical resistance

including

mineral acids

. Resistance to

petroleum oils

and fluids is low.
Silicone (SI):
Unlike the other elastomers which are based on the carbon atom, silicones are semi-organic and based on silicon-oxygen chains. They are resistant to water, ozone and sunlight and can be made to perform at very low or high temperatures (-100°C to 250°C).

Silicone

is odourless and tasteless and will not support bacterial life. It should not be use for steam at high pressures or with oils, petrols or other hydrocarbons.
Viton (FPM): - Viton is the registered trade name of Du Pont.
A copolymer of vinylidene fluoride and hexafluoropropylene. It will cope well with petrol, oils, chlorinated solvents, concentrated alkalis and fuming acids. Ozone and weather resistance are excellent and high temperature performance is good. It has poor low temperature flexibility and should not be used with some esters or ketones.

Corrugated gaskets

are manufactured from

corrugated metallic rings

in a wide range of materials. They are a

universal gasket

for a range of applications but are particularly suited to applications involving

narrow flanges

or where bolt loads are low.

Corrugated rings

are often supplied with a soft facing layer offering either full or partial coverage of the core. The layer, normally

graphite

or

PTFE

, improves the

sealability

of the product and ensures high integrity even at

low gasket loadings

. Due to the

sealing

characteristics of faced

Ring Type Joints:

Metallic Ring Joint Gaskets:
Metallic Ring Joint Gaskets PDF - 360 KB

Metallic ring joint gaskets

are heavy duty,

high-pressure gaskets

largely used in offshore

petrochemical applications

. They are precision-engineered components designed to be used in conjunction with precision-machined

flanges

. All our

Ring Joints

are manufactured according to ASME B16.20 and API 6A.

The

gasket material

is selected on a number of grounds primarily; chemical compatibility with the media and the hardness of the

flange

. The

gasket material

ideally needs to be roughly 30 Brinell less than the

flange material

to ensure sufficient deformation of the

gasket

without damaging the

flange facing

.

Worn, pitted or corroded

flange sealing surfaces

can impede the sealing ability of

RTJ gaskets

. In such instances, a serrated octagonal

RTJ gasket

, covered with

flexible graphite

, can provide a temporary or emergency solution until the

flange

can be repaired or replaced.
The following Ring Type Joint styles are available:

Serrated Metal Gaskets:

Maxiprofile:
Maxiprofile PDF - 573 KB
The

Klinger Maxiprofile

is a

composite gasket

, which utilises a

serrated metal

core with a

soft facing material

. The metal core is machined on each contact face with concentric serrations which provide high pressure areas, ensuring that the soft coating flows into any imperfections in the

flange

even at relatively low bolt loads. The result is a

gasket

, which combines the benefits of

soft cut materials

with the advantages of

seal integrity

associated with

metallic gaskets

.

Expanded graphite

is the most

common facing material

used for

Maxiprofile gaskets

. However, other materials can be used, such as

PTFE

for chemically aggressive duties or mica for high temperature duties.
General properties of Maxiprofile gaskets:
  • Have a wide range of seating stresses under which the

    seal

    is effected and maintained
  • Can be used when there is insufficient bolt load to

    seal

    conventional gasket materials

  • Easy to handle and fit
  • Suitable for a wide range of operating conditions

KLINGER Maxiflex:
KLINGER Maxiflex PDF - 201 KB
KLINGER Maxiflex PRO PDF - 165 KB

Spiral wound gaskets

have the ability to recover under the action of fluctuating loads caused by process fluid pressure and temperature changes,

flange face temperature

variations,

flange rotation

, bolt stress relaxation and creep.

The

gasket-sealing

element consists of a pre-formed

metallic winding strip

with layers of a softer, more compressible

sealing material

which, during compression, is densified and flows to fill imperfections in the

flange surfaces

when the

gasket

is seated. The metal strip holds the filler giving the

gasket mechanical resistance

and resilience.

spiral wound gaskets



Maxiflex Spiral Wound Gaskets

can be manufactured using a range of filler materials according to different service conditions.

Outer guide rings

are fitted to centralise the

gasket

between the bolts and to act as a compression limiter.

Inner rings

are fitted to reduce the gap between the inside diameter of the

gasket

and the bore of the

flange

. This reduces turbulence, erosion damage and protects the

gasket sealing element

from the contained media.

MERUS Technical Information

Merus Ring (Industrial Use):

Lime scale:
In a dissolved form, lime scale and corrosion as well as other salts can be found in almost any water. Calcite, is the main cause of scale and is the most common form of calcium carbonate which occurs naturally as an ingredient of Chalk, Limestone and Marble.
For every 6mm of lime scale build up, 40% more energy is used.
Corrosion:
Rust or Iron oxide is often found in steel or iron pipe work, or system with iron components. This leads to poor water quality, high maintenance costs, or premature failure of equipment.
Algae and Bacteria:
Algae can be found in open systems, such as cooling towers, fountains or ponds, and it will proliferate primarily in warmer surroundings.
Legionella:
Water suppliers provide water, free of microbiological contamination, however press reports indicate that Legionella is being identified and organisations are at risk of contamination.
The Solution – MERUS®:

Merus

has been working at the root of the problem for more than ten years. All conventional technologies on the market – whether chemical or physical work only at point of installation. The

Merus

unique oscillation technology can achieve the desired results.

The

merus rings

do not require servicing or maintenance. Trial installations of the

Merus ring

can be carried out easily, quickly, without any alterations to the

piping

and without any operational or financial risk.

The demands of the

marine industry

coupled with our indepth knowledge of your needs means we can reduce concerns on

Lime scale

, rust and

waterborne bacteria

without the need of chemicals.

Corrosion:
Rust or Iron oxide is often found in steel or iron pipe work, or system with iron components. This leads to poor water quality, high maintenance costs, or premature failure of equipment.
Marine Growth, Algae and Bacteria:

Marine growth

is a constant concern for various marine applications such as seawater intakes where mussel and crustacean growth can be found. Algae and bacteria (including legionella) are found in open systems such as swimming pools and many other applications.

Merus Ring (Petrochem Use):

Scale:
Most conveyed crude oils contain big amounts of paraffin wax. This leads to scaling in oil and gas lines, causing the same problems as

lime scale

in water.
Corrosion:
Crude oil contains very aggressive substances corroding pipes and machines throughout the whole refining process. H2S produced by SRB’s or originating from the well itself make it even more difficult to slow down or prevent corrosion.
Emulsions:
While transporting oil and water mixtures in pipe work emulsification occurs . For environmental and financial reasons this has to be separated out.
SRB:
Sulphur reducing bacteria will occur in a lot of crude oils, they are responsible for extensive corrosion within the

oil and gas industry

.
Biofilm:
In technically used water, especially in open systems, there is a high possibility for algae or bio film to develop. Microorganism spawn and form scale in pipes and machines. This so called bio film reduces heat transfer and in some cases even clogs up whole systems. There is even bacteria which will support corrosion.
