Seamless steel tube

Seamless steel tube SR EN 10216-1

Fields of application

Galvanised pipes made from carbon steel are destined for cold and hot water transport networks, for heating installations (where the pressure does not exceed 50 bars), also for tehnological installations. The superior quality of the used material, allows to estimate a minimum lifespan for the product of 15 years, respecting the proper anticorrosion protection measures.

Aspecte

The exterior and interior surfaces of the pipes must be smooth, corresponding to the fabrication procedure. The pipes' inner and outer surfices must not show fissures, overlays of material, bubbles, non-metallic inclusions or other defects visible with the naked eye. Small bumps, dents, jags and traces from cleaning surface defects, with the condition that the deepness of these will not exceed the negative tolerance of the wall thickness.

For pipes with an inner diameter under 15 mm smoothness of the interior surface is not guaranteed.

Delivery conditions

The pipes are delivered with cold hardening or heat treatment. Those with heat treatment (normalized) are delivered with oxides formed in the technological process of manufacturing. At request they can be delivered also in other terms of the surface aspect (normalized in neutral atmosphere N.A.N. pickled, etc.)
