Product description

Notes
The pressure figures are based on straight tubes.
The appropriate wall thickness needs to be calculated for tubes with bends as stipulated in DIN EN 13480-4.
Description
In modern pipework technology, the highest demands are placed on surface coatings. Our answer to these demanding requirements are Zistaplex pipes, which are equipped with an organic EPOXY ≤ 50 μm top coat in addition to the galvanised surface. This innovative Zistaplex surface impresses with its outstanding processing properties, particularly in terms of flexibility. Another advantage of Zistaplex pipes is their compatibility with DIN and SAE fittings and the fact that they can be formed without removing the coating. The coated precision tubes in accordance with EN 10305-4 are available in many different dimensions. You too can benefit from the outstanding corrosion protection and excellent forming properties in the construction industry, agriculture and forestry, mechanical and plant engineering and other sectors.
