Steel round tubes 33,7 x 4 mm (1") - Heavy
Stahl (Material)
Product information
Welded black steel threaded pipe – EN 10255 Heavy
These steel threaded pipes are welded steel pipes in accordance with EN 10255, Heavy series. The pipes are manufactured from non-alloy steel and, due to their increased wall thickness, are suitable for threaded connections subject to higher loads. Production is carried out using a longitudinal welding process, resulting in a round pipe with uniform wall thickness distribution and mechanical properties compliant with the standard. Delivery condition is black (raw) without additional corrosion protection.
Main features
- Standard: EN 10255
- Series: Heavy (increased wall thickness)
- Manufacturing: Longitudinally welded steel pipe
- Profile shape: Round pipe, suitable for threading
- Surface: Black / raw
Note: Due to the manufacturing process, the pipes feature a longitudinal weld seam which is process-related and does not constitute a quality defect. Surface characteristics such as mill scale, minor scratches, discoloration or transport marks may occur. Sawed or cut pipe ends are unfinished and not deburred. Threads may be factory-applied depending on the version or intended for further on-site machining.
Material properties:
- increased wall thickness for more durable threaded connections
- good weldability
- material-typical strength properties
- uniform wall thickness distribution according to Heavy series
Technical specifications
- Standard: EN 10255
- Series: Heavy
- Manufacturing type: Longitudinally welded
- Surface: Black / raw
- Thread: Suitable for pipe threads according to common standard systems
- Lengths: Standard lengths or custom cut
Dimensional and weight tolerances comply with EN 10255. The black delivery condition does not provide permanent corrosion protection. For outdoor or corrosive environments, an appropriate surface treatment is required.
Applications
- Piping and installation engineering
- Threaded connections with increased mechanical load
- Technical constructions
- Plant and supply engineering
Delivery is made as a welded steel pipe in accordance with EN 10255 Heavy series. Production-related deviations within permissible standard tolerances are possible.

Solides Konstruktionsrohr nach Maß
Das Stahl Rundrohr bzw. Konstruktionsrohr wurde ordentlich zugeschnitten und kam gut geschützt an. Die Wandstärke und Verarbeitung wirken zuverlässig, das Rohr lässt sich gut für stabile Konstruktionen einsetzen. Besonders positiv war für mich, dass die Länge genau wie bestellt gepasst hat. Für Metallbau und Werkstattarbeiten eine gute Wahl.
