Perfect resistance.
Orobica Plast-Gom is highly experienced in elastomer technology and specialized in the production of gaskets for plate heat exchangers. Its technical division works alongside customers and designs different types of gaskets to satisfy the market, based on a simple drawing or an existing sample. All the departments are equipped with technological machinery and highly qualified staff, who first make the moulds and then the gaskets, which are vulcanized by compression or injection technology. The company is capable of making gaskets of any material, shape or size and for any type of heat exchanger. The gaskets are mounted using glue or clips. Orobica Plast-Gom also collaborates with world-renowned research labs to improve existing mixtures as well as study and test new specific elastomers. This means that it can guarantee more efficient, durable and reliable gaskets even when used in heavy-duty industrial applications, therefore cutting maintenance time and running costs.

These seal rings are normally used in sets as valve stem or reciprocating pump packings. A set is usually made up of a male and female end rings for ease of seating in the gland.
Two standard 'V' forms are used. The first 60° and 90° levels for low and medium pressure service, and the second has 90° levels only, for high pressure service. In both cases a central gap is formed to give the flexure required under pressure.
The number and combination of rings per set is dependent upon the pressure and the depth of the gland. |

| Broad chemical resistance, except against liquid alkaline metals and fluorine gas under pressure. Good sliding qualities, low wear and tear. Temperature range from -200 °C to +260°C. PTFE has hardness of approximately 95 °Shore and installing these O-rings in split grooves is recommended or alternatively the use slit or sheathed types due to the low elasticity. |
|
| All SENTINEL® Filter Bags utilize the patented SENTINEL® seal. It's all plastic, polypropylene, polyester or Santoprene® construction, provides a flexible, chemically resistant seal which adapts to any filter housing. This unique design employs a pressure activated sealing lip which responds to increases in differential pressure. As the pressure increases, the seal of the ring improves, insuring by-pass free performance over all ranges of pressure, temperature and micron rating. The elevated bag handles make removal of the bag from the vessel quick and easy. When a SENTINEL® Filter Bag is installed into an Eaton Filtration Housing, the ring snaps into place, holding its position until the housing is closed. |

Resilient Metal Seals
Metal-to-metal seals: the innovative route in static sealing
Process developments over the past thirty years, demanding ultra high vacuum, high temperatures and pressures, have driven the need for advanced technology seals. Michel Le François, Research and Development Manager of Sealing Technology business Garlock, explains how metal-to-metal gaskets have evolved to comply with the most demanding requirements.

THE MATERIAL
Butyl: The polymer butyl (IIR - isobutylene isoprene - rubber) is an elastomer with a small number of double bonds, produced through co-polymerisation of isobutylene and isoprene.
EPDM: The polymer EPDM, ethylene-propylene rubber, is produced through co-polymerisation of ethylene, propylene and diene monomer, producing a polymer made up of saturated linear macromolecules with a paraffinic structure.
In addition to the base polymer, both EPDM and Butyl contain reinforcing carbon black, fillers, process chemicals, antioxidants and vulcanising agents. After mixing the ingredients into a homogenous plastic compound, two layers of the rubber are rolled out in a calender to form a double sheet. Vulcanisation is then carried out. The long rubber molecules in the material are cross-linked through heat and pressure, creating an elastic membrane.
RESISTANT TO THE ENVIRONMENT
The vulcanisation process means that the material differs from all thermoplastic products, in that its properties are not affected by varying temperatures. The product is chemically stable and always returns to its original dimensions after stretching.
The cross-linked molecular structure gives EPDM and Butyl rubber their unique properties. Ageing or changes in characteristics are negligible despite decades of exposure to the atmosphere, sunlight, UV radiation, chemical fallout, water or major temperature fluctuations.

Rings & Bushing
Manufacturing a customized seal ring in link with specifications, and machining it to the required degree of flatness are not major engineering challenges. The problem is that the ring must remain flat to function regardless of application and environment. Wear resistance, toughness, corrosion resistance, and resistance to thermal shocks are the key material properties required for long-lasting, all-perfect pump function.
The unique combination of all these material characteristics has made cemented carbide the most widely used material in pump seals and bearing in the sewage, mining and process sectors. Moreover, there is further potential to tailor cemented carbide for a vast range of environment applications.
Cemented carbide can be made harder than the hardest steel, but yet remain tougher then ceramics. |

VITOSEAL multi-purpose vinyl foam sealing tapes - ensure permanent air- and water-tightness, sound absorption, heat and cold insulation
VITOSEAL consists of an one-side self-adhesive vinyl foam with a paramount resistance to ageing and weathering conditions.
The flexible and elastic consistency of these products permits an easy adaptation of uneven surfaces, allowing thus an optimal sealing.
The water-tightness is already achieved at a compression of about 30 %. VITOSEAL vinyl foam tapes show an elevated vapour diffusion tightness. In general, they are resistant to water, fungal attacks and oxidation; in addition, they are resistant to diluted acids and weak alkaline solutions in commercially available brands with normal concentration.
These tapes should not be applied in direct contact with plexiglass. When entering into contact with plexiglass, it is advisable to change over to other foams.
