Stainless Steel
Low weight, high strength
Despite their small and practical weight, CAINOX stainless steel products are very robust and offer the advantage of being a strong material that is easy to handle and install. CAINOX drainage products are manufactured in AISI 304 grade stainless steel, and for the most demanding environments in AISI 316L grade.
Flow rate, hygiene and easy maintenance
With the right treatment, stainless steel has an exceptionally smooth surface that ensures excellent flow capacity, which in turn minimises dimensions. This, combined with the ease of cleaning and maintenance, makes stainless steel the ideal choice for drainage installations.
Quality, long service life and lifetime savings
CAINOX stainless steel solutions are also competitive in price. Calculating installation time, maintenance and service life, over a realistic period of say 50 years, stainless steel solutions are unrivalled.
Environmentally friendly
Stainless steel is 100% recyclable and non-toxic. Should the system require replacement parts, disposal of the materials is not an ecological problem.
Fire safety
Stainless steel withstands extremely high and extremely low temperatures. Able to withstand temperatures in excess of 800°C, stainless steel is classified as a fire resistant material.
Design
If you are looking for an elegant, high-tech style, stainless steel is the best choice. Stainless steel is a classic and timeless material in terms of design.

Corrosion resistance
Austenitic chromium-nickel steel (AISI-304) is the most widely used of the stainless steel grades, as it has very good corrosion characteristics, and is therefore used in various sectors, for example in the food industry, shipyards, chemical and pharmaceutical laboratories, breweries and dairies, as well as in hospitals and industrial kitchens.
If a higher acid resistance is required and there is a risk of corrosion, chrome-nickel steel with a molybdenum alloy can be used. (AISI-316 L)
Resistance to deformation
The resistance to deformation of stainless steels (AISI-304 and AISI-316L) is of high structural quality at any temperature.
It is also resistant to deformation caused by shocks or heavy loads and therefore tends to deform slightly but not to break.
Fire resistance
Stainless steel is non-flammable
Classification: Stainless steel tubes
DIN 4102: Fire class A1 - non-flammable
DIN 1986, T4: non-flammable.
This means that stainless steel pipes and drains do not require fire insulation.
In case of fire in stainless steel installations, the gases produced are not harmful.
Temperature resistance
Due to their low coefficient of expansion, stainless steel products for sewage pipes are not affected by temperature changes. Furthermore, these products do not need to be installed at specific temperatures.
The following table is based on laboratory investigations with pure chemical materials and should therefore be considered as a universal method.
A = Very good constancy for the limit values of materials
B = Moderate constancy
C = Limited or variable constancy
D = Minimum constancy

NOTE: Concentration levels and duration of contact have a direct effect on the resistance of stainless steel to certain chemicals. A small dosage of corrosive chemicals with an adequate volume of water will improve the corrosion resistance of the stainless steel. Each application should be carefully reviewed to determine the suitability of the stainless steel for the conditions.
The products offered by CAINOX meet all standardisation requirements and norms.
