Chemical hoses for industrial and analytical applications
When it comes to plastic products and hose technology, Reichelt Chemietechnik is your contact for high-quality and reliable solutions. Our range includes numerous rubber hoses and rigid tubing, including a variety of chemical tubes. Made from different polymers, chemical hoses open up numerous areas of application.
The products are available in a chemical-resistant version and also are used in the beverage and food industry, for example in dairies and bottling plants. For industrial applications, various pressure hoses in double-jacket or with integrated steel wire braids are used. Ventilation and suction hoses, which can withstand both pressure and vacuum loads, are needed for conveying large volumes of gas. In explosion-proof areas ("Ex protection", "spark protection"), where static discharge and spark formation must be avoided, antistatic tubes that are electrically conductive are the tool of choice. And in welding technology, special welding products - so-called oxyfuel hoses - are used.
However, this list only provides a rough overview of the hoses offered in the field of chemistry, as the list of specialty hoses is far from complete. One thing is for sure: no matter how specific your application may be, Reichelt Chemietechnik is your contact for the right hose solution.
Chemical-resistant hoses in numerous variations: Focus on materials
Nowadays, many technical polymers are available as tube materials. Which one is suitable for your application depends on various parameters. Does the material need to be chemically resistant? If so, against which media? What about the pressure and temperature load? Is the flexibility and coloration of the hose line relevant?
These are just a few questions you should ask yourself before choosing tubing. Which materials are offered for chemical hoses and what individual benefits they bring will be detailed further.
EPDM
The elastomer EPDM (ethylene propylene diene monomer rubber) is resistant to many acids, alkalis, alcohols, and solvents. Chemical tubing made from this material are soft, flexible, and also resistant to aging, weather, and ozone. The temperature resistance varies by hose design, ranging from about -40 °C to +130 °C. EPDM is also used for hot water and steam hoses as well as compressed air hoses and brake tubes.
EPDM technology also includes high-performance hoses for process technology, chemical technology, and medical technology. FDA-compliant pump tubing made from the material compound EPDM/PP have a fixed place in laboratory analytics, pharmaceutical technology, and medical technology. They are also manufactured as micro tubes, some equipped with two or three stoppers.
EVA
EVA (ethylene vinyl acetate copolymer) tubes are of particular importance for chemical and beverage technology, as their gas permeability is extremely low. EVA is also characterized by high chemical resistance and excellent mechanical strength – yet remains flexible. Depending on the tube dimension, operating pressures up to 20 bar at +20 °C can be achieved, and the temperature resistance of the copolymer ranges from -30 °C to +60 °C.
FKM Fluoroelastomer FKM, also known as FPM and available on the market, along with its close relative, FFKM, is probably the most chemically resistant elastomer on the market. It is therefore no surprise that FKM is used as a pressure and chemical hose and these versions are widely used. In addition to the chemical resistance mentioned above, the temperature resistance of -20 °C to +200 °C is also noteworthy. FPM hoses are also suitable as pump , pressure and gas hoses, as their gas permeability is particularly low. Food-grade and FDA-compliant versions are also available.
FEP
The fluorinated plastic FEP (fluoroethylene propylene) is characterized, like most other technical fluoroplastics, by high chemical resistance, pressure resistance, and temperature resistance. However, unlike PTFE (polytetrafluoroethylene) or PVDF (polyvinylidene fluoride), FEP hoses can also be used at very low temperatures. Thus, the permissible temperature range is about -170 °C to +200 °C. Another advantage that fluoroethylene propylene has over other fluorinated plastics is its high translucence. Unlike PVDF or PTFE, which are often very milky-white and not very translucent, FEP is almost transparent and clear.
FEP is an important part of tube technology. Additionally, chemical, corrugated and composite hoses made of plastic are available. These are used for conveying liquids and gases in laboratories, technical centers, and pilot plants. But it is also used for medical, biological, and analytical research applications, especially in the field of biotechnology.
MFA
MFA (modified fluoralkoxy) chemical tubes withstand extreme mechanical and thermal loads. They are also highly chemically resistant, even against oxidizing acids and mineral acids. They are also resistant to organic media such as (aliphatic) hydrocarbons, aldehydes, esters, ketones, and amines. They are also available as corrugated tubing, which can be used from -200 °C to +240 °C.
NBR
The rubbery and flexible elastomer NBR (acrylonitrile butadiene rubber, Perbunan®), also known as nitrile rubber, is often used as a material for fuel hoses, as it is resistant to mineral oils and aliphatic hydrocarbons, such as gasoline or diesel. Various types are offered from NBR - double-jacket, hot goods, drinking water, paint spray, suction and pressure hoses as well as gasoline and oil hoses are available. But NBR formulations are also used for food hoses, tank truck, filling station, water and washing machine hoses. The temperature resistance, depending on the product type, ranges from about -20 °C to +100 °C.
It is worth mentioning in this context the NBR water hoses in thin-walled design, which can also be provided for the largest dimensions of up to 90 mm inner diameter with an outer diameter of 95.6 mm.
PEEK
PEEK (polyetheretherketone) is a real high-performance plastic, which is used, for example, in aerospace and aviation. It is exceptionally temperature-resistant, chemically resistant, and has the best mechanical properties. PEEK chemical tubes are mainly offered as high-pressure capillary hoses and can withstand a maximum working pressure of 420 bar at +20 °C. They thus represent the ideal hose technology for analytical applications, such as in laboratory analytics and HPLC. The maximum working temperature is also noteworthy: In the range of -40 °C to +250 °C, briefly even up to +300 °C, the capillary hoses can be used.
PFA
Chemical hoses made of PFA (perfluoroalkoxy) have their place in apparatus engineering, process technology, chemical technology, and process engineering as well as in laboratory analytics and (small) industry. It is another representative of the hard fluoroplastics. The chemical resistance is, as with PTFE and FEP, excellent. A special feature, however, is the extremely wide temperature range in which tubing made of PFA can be used, namely from -260 °C to +280 °C. Thus, not only very hot media can be conveyed, such as flue gases and chemical vapors, but also very cold ones, such as liquid nitrogen. They are also produced as corrugated tubes, optionally equipped to be antistatic (electrically conductive). But they are also used as laboratory tubing in small dimensions, also available in electrically conductive or antistatic versions.
PTFE
PTFE (polytetrafluoroethylene) is a real all-round plastic. Hardly any chemical can attack the fluoroplastic - only elemental fluorine and molten alkali metals are capable of doing so. With a working temperature range of -200 °C to +260 °C (briefly up to +280 °C), they are also extremely temperature-resistant. It is therefore hardly surprising that the universal plastic is used for a wide variety of chemical hoses.
PTFE tubing comes in color-coded, thin-walled, and micro-thin-walled variants. The product line includes capillary tubes in inch dimensions, corrugated tubes, suction and pressure lines, and high-pressure components. These products are also manufactured with antistatic properties (electrically conductive) for use in explosion-protected areas ("Ex protection"), with discharge resistance of <106 ohms. Our selection features various PTFE chemical transfer lines, available for purchase in lengths starting from one meter.
PVDF
The material PVDF (polyvinylidene fluoride) is used for chemical tubes that are of great importance in pharmaceutical technology, process technology, laboratory analytics, and food technology. Naturally, they are at the forefront in the production area of chemical technology. They are high-temperature resistant, mechanically of the highest strength, and dimensionally stable. At the same time, PVDF hoses are highly resistant to inorganic and organic media. The Reichelt Chemietechnik program includes both PVDF chemical hoses, spiral hoses, corrugated tubes, pressure pipes, and heat shrink tubes. In addition to technical hose versions, there are also those available that meet the regulations according to BfR (Federal Institute for Risk Assessment) and are thus considered physiologically safe.
PVC
PVC (polyvinyl chloride) is the polymer of choice when an inexpensive chemical tube is needed for low to moderate critical operating conditions. The elastomer is inexpensive, flexible, and at the same time pressure-resistant. The chemical resistance is not comparable to that of fluorinated plastics, but still sufficient for many industrial applications. Thus, PVC tube systems are resistant to aliphatic hydrocarbons, such as lubricants and fuels, various acids, alkalis, amines, and also hot water. Special PVC gasoline and oil tubes are available for the conduction of oils, fats, gasoline, diesel fuels, and other (aromatic) hydrocarbons. The working temperature range is about -20 °C to +70 °C, depending on the hose type.
TPE
The group of chemical hoses also includes TPE (thermoplastic elastomers) food hoses as well as TPE-S hoses for medical and pharmaceutical technology. They have excellent resistance to many acids and alkalis, aliphatic hydrocarbons, fats, oils, and highly concentrated alcohols. They are free of plasticizers and of great importance in pharmacy, the food industry, and medical analytics. The temperature range is exceptionally good for an elastic polymer, at -40 °C to +120 °C. TPE hoses comply with EC Directive 10/2011 as well as USP regulations and are thus considered physiologically safe. Sterilization is possible by autoclaving, but can also be done using hot air, ethylene oxide, or gamma rays.
