Step 2: What is the application?

What kind of requirements does the application set for the hose?

Please visit our website for more information on this topic.

Clean / food contact

Do you need to be sure that the hose does not add any flavor, smell or color to the transferred chemical? In this case the hose needs to be food contact safe. The strictest regulation comes with German BfR (previously BGA). Also U.S. FDA regulation and EU regulation provide a framework for manufacturers.

If the hose meets the requirements, it&#;s marked with standard icon or there&#;s a mention on the datasheet.

Teknikum&#;s clean chemical hose is Teknikum MULTI-TEK&#; SD UPE Clean with blue cover and Teknikum MULTI-TEK&#; SD UPE Pro with black cover.

Also, take a look to our special Teknikum FOOD-TEK® Food quality hoses.

Oil-free chemicals / sulfuric acid / aging

EPDM (ethylene propylene diene monomer rubber) hose is compatible with basic substances, such as fireproof hydraulic fluids, ketones, hot and cold water, and alkalis. It is incompatible with most hydrocarbons &#; oils, kerosene, aromatic, gasoline, as well as halogenated solvents.

Benefits? EPDM provides outstanding resistance to heat, ozone, steam and weather. It can also withstand sulfuric acid up to ~65-70% concentration. Although the raw material is naturally an electrical insulator, our compound mix provides electrical conductivity for safety.

Note! The electrical conductivity of chemical hose assemblies must always be checked. Conductivity is determined by measuring the electrical resistance through the assembly from connector to connector. Electrical resistance must be measured from all installations for the transfer of flammable substances and from objects where static electricity is generated or used in potentially explosive atmospheres.

Teknikum provides hose Teknikum CHEMO-TEK® SD EPDM for this kind of use. The hose meets the requirements of EN : and is ATEX compliant.

Most chemicals / powdered solids / color pigments

UPE hoses made with chemical resistant UHMWPE-film (Ultra High Molecular Weight Polyethylene) are suitable for 98% of industrial chemicals. As lining material UHMWPE is odorless, tasteless, and nontoxic, as well as highly resistant to abrasion.  The hoses meet the requirements of chemical hose standard EN :.

Benefits? Our recommended multi-purpose hose for chemical industry. The inner lining is great in the transfer of powdered solids. For example, the substance of a color pigment is very fine and contagious. The UPE lining lasts this well and does not cause blockages in the transmission line. It can be also used for the transfer of dry tea due to the slippery surface.

Our high-quality hose series Teknikum MULTI-TEK&#; offers suitable options for most industrial chemicals in various forms.

Oil-based chemicals / petrochemicals

Typically oil creates a challenge for rubber hoses. For oil based substances and petrochemicals we have developed the high-quality Teknikum FUEL-TEK® hose series.

These hoses meet the chemical hose standard EN : for transportation of all oil-based materials. Our hoses are suitable e.g. for gasoline, diesel oil and oil mixed water.

Bio-based chemicals / natural gas

These chemicals include e.g. bio-based aromas for fragrances and flavours, resins, lubricants, natural fertilisers, some industrial and household cleaners and solvents as well as drop-in biofuels and other fuels produced from biomass sources.

Typically RME (biodiesel) creates a challenge for rubber hoses, but some synthetic compounds are suitable. With this application a case specific check is always needed &#; please consult our lab for a suitability recommendation.

Teknikum recommends hose Teknikum FUEL-TEK® D Lypo for lead-free and E10 gasoline. For natural gas we offer Teknikum FUEL-TEK® SD Gas LPG/LNG.

Corrosive chemicals / concentrated acids

When transferring the most aggressive chemicals, hoses inner lining must be made out of PTFE (Polytetrafluoroethylene) or FEP (Fluorinated ethylene propylene). This kind of hose withstand for example fuels, solvents, oils and corrosive chemicals. FEP and PTFE both share the useful properties of low friction and non-reactivity, but FEP is superior to PTFE in applications involving exposure to detergents.

Teknikum offers Teknikum FLUOR-TEK® SD PTFE and Teknikum FLUOR-TEK® SD FEP.

Ceramic Hose

Good quality high wear resistant ceramic lined rubber hose, In the newly developed ceramic hose, ceramic tiles are used to eliminate a disadvantage in conventional ceramic hoses. It has higher abrasion resistance while maintaining flexibility. Ceramic hose has the circular disk shaped ceramic tip as compared with the conventional ball shaped ceramic tip and shows several times higher abrasion resistance.

Feature & Quality:

• Wear-resistant: Ceramic lining hose is 12 times more wear-resistant than stainless steel hose.
• Impact resistant: Virtually impossible to destroy the ceramic segments.
• Flexible: Minimum bend radius is roughly 12 times of the hose I.D.
• Corrosion-resistant:Compatible with most chemicals found in slurries.
• Widely of end-connections: Suitable variety Fittings and Flange.
• Long Length: Purchase any continuous length up to 65 FT.
• Widely hose diameter: 28 to 300 mm in hose diameter.

The Flexible Hose with ceramic tiles:

Flexmic are used to use the flexible hose with ceramic balls to reduce the internal costs. Our R&D experts were developed the ceramic tile has roughly five times longer useful life than flexible hose with ceramic balls.

How to selection ceramic hose:

The right selection means choosing a product suitable for technical requirements of certain application or device along with assurance of safe and faultless performance.Due to above mentioned reasons,we advise you contact us and help to choose the right ceramic hose.

The essential information for the right ceramic hose selection as follows:

• Medium: Substance conveyed
• Internal diameter: 25~300mm
• Pressure: Maximal working pressure
• Temperature: Both inside and outside temperature
• Hose endings: Type of fitting, thread size, type of sealing
• Way of assembling the hose fittings: Clip, band, clamp
• Length of the hose: Assembly the complete length along with fittings
