Why stainless steel for service water distribution

Process water, demineralised water, rainwater and pool systems are typically more chemically demanding than drinking water.

Molybdenum for resistance

AISI 316L contains 2–3 % molybdenum, significantly increasing resistance to pitting and crevice corrosion in chemically demanding media.

Wide pH range

AISI 316L reliably operates in media with pH ≥ 6.5. From demineralised water to industrial process liquids.

Chloride resistance

Certified for media with chloride content up to 600 mg/l. Significantly above the 250 mg/l limit for drinking water.

Temperature resistance

Industrial water at 110 °C presents no challenge for stainless steel. Unlike plastics, which lose strength under these conditions.

One material for everything

From rainwater through pool technology to industrial processes. AISI 316L covers the full spectrum without the need to change material.

Compatibility with water treatment

Stainless steel is inert to reverse osmosis, ion exchange and softened water. No degradation even with long-term contact.

Industrial process water is more demanding than drinking water. Higher temperatures, chlorides, aggressive pH — that is a challenge for the material.

TAVINOX PRESS in AISI 316L with molybdenum handles conditions where other materials fail.

Frequently asked questions about utility and industrial water distribution

What chloride limit does stainless steel piping have for utility and industrial water?
TAVINOX PRESS stainless steel piping made of AISI 316L is certified for chloride content up to 600 mg/l in industrial and process applications – significantly above the 250 mg/l limit applicable to drinking water under EU standards. The increased resistance is ensured by the 2–3 % molybdenum content in 316L steel, which protects the piping against pitting and crevice corrosion. For swimming pool environments with higher chloride concentrations, 316L is mandatory, not 304L.
Is stainless steel piping compatible with reverse osmosis and demineralized water?
AISI 316L is chemically inert to demineralized water, reverse osmosis water and ion-exchanged water – there is no material degradation or ion release into the medium. The TAVINOX PRESS system is suitable for distribution systems in laboratories, water treatment plants and industrial processes requiring highly pure media. The condition is maintaining pH ≥ 6.5, while strongly acidic environments below this value require individual assessment.
Can stainless steel piping be used for rainwater distribution?
Yes. TAVINOX PRESS is certified for the collection and distribution of rainwater from cisterns at operating pressure up to 10 bar and a maximum temperature of 25 °C. Both materials – AISI 316L and AISI 304L – are suitable for rainwater applications. Due to the variable chemical composition of rainwater (acidity, content of organic substances), disinfection with hydrogen peroxide is recommended. Chlorine disinfection is permissible up to 25 ppm for 24 hours, followed by flushing to a residual content below 2 ppm.
Which stainless steel piping material is suitable for swimming pool and water park distribution systems?
AISI 316L is the mandatory material for swimming pool and water park distribution systems – 304L is not suitable for these environments. Pool water contains increased amounts of chlorine and chlorides, which would cause pitting corrosion in steel without molybdenum. AISI 316L with 2–3 % molybdenum content withstands chloride concentrations common in pool technology. The TAVINOX PRESS system is available in 316L steel for sizes 15–108 mm in press connections and 133–323 mm in grooved connections.
What is the Leak Detect system and how does it protect utility water distribution systems?
Leak Detect is a safety feature of the TAVINOX PRESS system that indicates an unpressed joint before the pipeline is put into operation. An unpressed fitting allows the medium to pass through from a pressure of 0.1 bar and is visually marked by a blue indicator. This means the installation error is detected during the pressure test, not during a failure in operation. Leak Detect is a standard feature across the entire range at no extra cost and does not require any special tools.
How should TAVINOX stainless steel piping be connected to existing carbon steel systems?
The combination of TAVINOX PRESS stainless steel piping with carbon steel must be made via a brass dielectric fitting with a minimum length of 50 mm. The flow direction must always go from carbon steel to stainless steel – in the opposite direction, accelerated galvanic corrosion occurs. Combination with copper and other corrosion-resistant steel is unrestricted and does not require a transition piece. This rule applies to all utility and industrial water systems during reconstruction of existing piping.
