Rubber linings

LLC “Antikor Prom Service” offers a wide range of rubber lining materials produced in Germany by Steuler-KCH.

As materials are selected according to technical and economic criteria, rubber linings by Steuler-KCH become more widely applicable. Selection parameters are: temperature, size, anticorrosion properties and in certain cases such properties as abrasive resistance.

The application of rubber protection is economically useful. In combination with appropriate base material (usually steel) it provides a proper surface protection and is safe and reliable mean against corrosion.

Rubber lining has many advantages, such as:
  • High corrosion resistance
  • High resistance to mechanical loads
  • Excellent chemical resistance to acids, alkalis, salts
  • Excellent resistance to diffusion in corrosive environment
  • Long-term exploitation
  • High elasticity
We also apply soft or hard rubber lining on the production and construction sites of the Customer or in workshops, according to Your requirements. Our credo is – achieve the best results in the shortest terms.
Types of rubber protection

Natural rubber (NR) and polyisoprene rubber (IR). Are used not only in manufacturing of hard rubber, but also for soft rubber. As well as hard, soft rubber stands out for its effective exploitation properties, but its chemical resistance is lower. Soft rubber protection is mostly used in environments subjected to abrasive wear, but not to chemical attacks.

Chlorbutyl rubber (CIIR) and brombutyl rubber (BIIR), isobutylenisoprene rubber (IIR) (known as butyl rubber). It may be vulcanized only into soft rubber. However, vulcanized material has basically the same chemical resistance that hard rubber, based on natural caoutchouc. Another special property – high resistance of the material to vapor diffusion, sulphur trioxide, hydrofluoric acid diffusions and others. Isobutylen-isoprene rubber is known also for its effective weather and wear resistance.

Polychlorprene rubber (CR). May be vulcanized only into soft rubber, which in its turn is characterized by effective chemical stability, wear and weather resistance. Its resistance to halogenating oxidizing substances is not as high as in butyl rubber. Polychlorprene rubber performs higher fat resistance. Relatively high chlorine content over 25% also improves its self extinguishing properties, but its anti diffusion properties are much lower than of butyl rubber.

Chlorsulfonated polyethylene (CSM). May be used only in manufacture of different types of soft rubber. They are known for its high resistance to oxidative effects (for example, chlorine bleaching solution). In some cases soft rubber is produced of nitrile butadiene rubber (NBR). NBR-coatings stand out for their resistance to the largest number of organic chemicals.

Soft rubber:

Rubber lining Kerabutyl® BS. Vulcanized rubber based on chlorbutyl caoutchouc. It is used to protect steel and concrete constructions of chemical attack. It has perfect resistance to different acids and solutions. It is often applied as hydro isolative material in reservoirs and pits. It is used to protect channels, gas conduits, storage facilities, reservoirs.

Self-vulcanized systems, KERABUTYL® BBS and VULKOFERRAN have effective adhesion, and are easy applied to the surface under high temperatures, moreover it is resistant to high temperatures and very aggressive environments. Disadvantages: require vulcanization.

Kerabutyl VC rubber. Vulcanized rubber based on chlorbutyl rubber and polyvinyl chloride. It is used to protect steel and concrete constructions of acid corrosion. It has excellent resistance to concentrated hydrochloric acid.

Vulcoferran 2206 rubber. Self-vulcanized rubber based on brombutyl rubber. It is used in steel surface protection of chemical attack. It stands out for its good chemical resistance and high resistance to vapor diffusion. It is applied in protection of scrubbers in power stations, phosphoric acid plants, reservoirs, reactors, pipelines.

In some cases soft rubber is produced of nitrile butadiene rubber (NBR). NBR–lining stands out for its resistance to the largest number of organic chemical substances. Stirolbutadiene rubber (SBR).

Hard rubber:

Excellent chemical resistance to alkalis and acids, except oxidizing substances. Its field of application includes protection of flue gas absorbers in waste incineration plants, and also storage reservoirs and reaction reservoirs, with high exploitation temperatures.

Vulcoferran 2194 rubber. Hard rubber material with graphite filling based on polyisoprene-styrene-butadiene rubber. It is vulcanized in autoclave with hot water or steam. It is used to protect steel constructions of chemical attacks. It stands out for its chemical resistance to alkaline and acid environments.

Vulcodurit D3 rubber. Hard rubber material based on natural rubber. It is vulcanized in autoclave with hot water or steam. It is used for protection of steel elements in waste incinerators, in waste water treatment facilities, has a building technology institute admission as protection material of storage steel reservoirs for poisonous chemicals. Vulkodurit D3 is also applicable for in nuclear power stations with exposure limit up to 1 MGy. Vulcodurit D3 stands out for excellent chemical resistance, high diffusion resistance and good mechanical properties.

 

Example of correct application of rubber:
Our rubber linings have wide field of application:




  • For protection of medium and large steel technological equipment, like storage reservoirs, absorbers, bulk transportation tanks, evaporating apparatus, pipelines.
  • Technological equipment, effected to aggressive, corrosive fluids and gases, HCL, phosphoric acid and flue gas purifiers
  • Pressure vessels and vacuum enclosures
  • Concrete vessels and pits
  • Railway, road tanks
  • Reaction tower
  • Pipelines in chemical industry
  • Chemical industry: production of chlorine, colors, lime
  • Transportation industry: road tanks. Flue gas desulphurization, waste incineration, coal-fired power stations

Main fields of application:

Pre-vulcanized rubber lining:

  • Storage reservoirs
  • Phosphoric acid production

Self-vulcanized rubber lining:

  • Absorbers for flue gases desulphurization
  • Power stations and waste incinerators
  • Phosphoric acid production

As a protection against attack of acids, caustic and brine solutions, different chemical substances or vapors a rubber lining thickness 3-6mm is applied. In case of mechanical loads (pressure, abrasion) protective layers appropriately strengthen.

We apply rubber exactly there where you need!

In reservoirs or pipes – our rubber materials ®VULCOFERRAN, ®GENAKOR and ®VULKODURIT will always protect of chemical or thermal stress. To reach the best results – this is our credo. Removal of the existing covering and shot-blasting - is basis of surface rubber protection process. To provide the effective adhesion of rubber to steel primer and adhesive are applied onto the steel surface, then, rubber sheets are applied manually onto the surface, using special coating materials.

Lining in workshops and other places are performed by our trained specialists. We also carry out vulcanization and testing by ourselves - this is the only way to guarantee the compliance of our lining to our quality standards.

The quality is provided by professional work on each stage –from materials manufacturing, selection of special components, rubber and coatings to control of the finished work.

Rubber linings in the construction sites

  • Steam vulcanization (pressure, temperature)
  • Steam vulcanization under standard pressure
  • Hot-water vulcanization
  • Cold vulcanization

The rubber lining is carried out on site, if sizes of the parts to be protected are too big for vulcanization in the autoclave. We use vulcanized sheets and self-vulcanized rubber material on site.
