Corrugated metal gaskets have been proven to be both reliable and cost-effective for the application on flanges
and heads where bolt loading is sufficient. They operation principle is based on different degrees of hardness of
adjacent materials. The sealing effect is produced by the constant load to which a gasket is exposed. They are
used in applications, which require mechanical strength, thermal conductivity, as well as temperature and corrosion
resistivity. They can be classified into flat, serrated and corrugated types, and are particularly useful when
compressibility is not a factor and where sufficient clamping force is available. Metal gaskets feature greater
mechanical strength, better heat transfer and resistance to higher temperatures and pressures, and can offer
advantages over the clad type gaskets in certain applications.
The Corrugated metal gaskets with soft layer on both sides are used in low-pressure applications, in large diameter
flue gas ducts at high temperatures. The use of corrugated gaskets eliminates the problem of difficult handling with
large non-metal gaskets used in those applications.They are suitable for gas pipes and valve caps, or wherever
acids, oils and chemicals are found. They can be used at lower pressures and higher temperatures.
Advantages:
Outstanding mechanical strength and thermal conductivity
Capable of withstanding high temperatures
Almost no limitations regarding size
Solid construction provides stability even for large diameters and ensures trouble-free handling and installation

The metal gaskets are produced in several types to meet the most demanding applications,Corrugated Metal Gaskets, gasket,seal
W201 Flexible Graphite Ring
W201D Die Formed Graphite Rings
Die-formed Graphite Ring is made of low-sulphur expanded graphite without any fillers or binders. They are
compressed in precise moulding tools to the required density. Due to the high purity of the material (>99%), no
special corrosion protection is required. In general, it has square section and also has V-shaped and wedge-
shaped section, the rear two kinds style are suitable for high pressure sealing.
W201R Reinforced Graphite Rings
Moulded from pure flexible graphite with reinforcement, the insert materials stainless steel foil or mesh etc. are
available on request. To protect against oxidation, the stainless steel cap is necessary.,Flexible Graphite Ring, graphite product,graphite material
Wealson offers carbon and graphite felts in a variety of widths and thicknesses to meet a wide range of
applications. These products are easy to cut and install. The felts can be sewn in place using carbon cordage. Felt
material is generally used as thermal insulation in inert and vacuum furnaces. For special applications, this felt is
available with graphite coatings which will reduce the permeability of the felt and improve its resistance to erosion.
Wealson's felt can be surface coated with graphite foil bonded or combined with carbon/carbon face plates to
provide an insulation system that is utilized with operations such as rapid gas quenching, resulting in longer useful
life of the insulation system. Additionally, Wealson's carbon and graphite felt is available in a rigid form that can be
manufactured into various shapes, including: Baffle, Cylinder, Ring and Board.

Wealson Carbon Black is a tiny powder that is caused by incomplete combustion of carbonaceous raw materials
(petroleum or coal tar). The appearance is pure black fine grain or powder. Carbon Black does not dissolve in
water, acid or alkali, and it can turn into carbon dioxide while burning in the air.
Wealson manufactures carbon black from N100 to N700, including N115, N121, N220, N234, N330, N339, N375,
N550, N660, N762, and etc. Wealson Carbon Black, as the brand name, is complied with the standard of GB3778-
2003/ASTM, its major applications are used in tyre, rubber and plastic as reinforcing filler.,Carbon Black, carbon black,carbon material,carbon product
Camprofile or "Grooved" Gaskets manufactured by Wealson can be used in all industrial applications where high
pressures and temperatures are maintained and consequently high bolt loads need to be controlled, such as
industrial power plants, the primary circuits in nuclear installations, Petrochemical and Chemical industries. It is used
either between flanges or in heat exchanger units in nuclear applications.
Wealson is a manufacturer of gaskets for heat exchangers, compressors, condensers, pumps, valves, and general
industrial applications in all sizes & shapes.
We manufacture standard size gaskets, non-standard size and custom gaskets from metal and other composition
sheet material for the petroleum and natural gas industry, power generation, food service and pharmaceutical
industries as well as the commercial transportation industry. We operate nationally and internationally via direct
marketing as well as through a network of distributors and dealers.

Pure PTFE fiber braided packing is a braided packing made of PTFE yarn without soaking any PTFE dispersion
and lubrication but with greatly enhanced ability to seal high speed shafts with the addition of inactive and heat-
resisting agents. It is recommended for chemical engineering, foodstuff, pharmaceutic where contamination is not
allowed. Also it can be applied to seal all chemicals except molten alkali metals.<BR>Main specification of Pure

Metal Jacketed Gaskets manufactured by Wealson, as the name suggests, are comprised of a metallic outer shell
with either a metallic or non-metallic asbestos free filler. The filler material gives the gasket resilience, while the
metal jacket protects the filler and resists pressures, temperatures and corrosion.
Metal Jacketed Gaskets are manufactured using hand made techniques, and are available in a wide range of sizes
and configurations.
They are traditionally used for heat exchanger applications, pumps and valves, however the resilience and recovery
properties of these gaskets are limited. Metal Jacketed Gaskets require smooth flange surface finishes, high bolt
loads and flange flatness in order to seal effectively.
A wide range of materials are available to suit specific temperature and corrosive conditions.
Metallic: Aluminum, Brass, Copper, Soft Iron, Stainless Steel, Monel, Nickel, Inconel
Non-Metallic: Flexible Graphite,Asbestos, Non-asbestos, PTFE,Ceramic

Wealson offers a complete line of standard and custom gaskets produced to the highest standards.
PTFE gaskets are excellent in applications involving solvents,corrosive chemicals and high temperatures.
There are different types of PTFE gaskets for each particular sealing application: ring, full face, flange and
envelope gaskets.
A PTFE envelope gasket is a gasket that is split or machined from the outside diameter wall to 1/16 of an inch from
the inside diameter. Envelope gaskets can be supplied slit/v-type or milled/square cut with or with out a filler.
A ring gasket has a thickness, inside and outside dimension.
A full face gasket has a thickness, inside and outside dimension along with bolt holes.
A flange gasket is primarily the same as a full face without the bolt holes.
These gaskets are available in standard and metric pipe sizes up to 60" outside diameter., PTFE Gasket, gasket,seal
