Ends of the API 5L X70 PSL2 Pipe

Ends of tubes are smooth, without threads.
From 60.3 diameter beveled according to standards:
DIN, EN – a = 40° – 60°, c = to 2 mm
ASME – a = 75° ± 5°, c = 1,6 ± 0,8 mm

Marking of API 5L X70 PSL2 Pipe and tube bundles

Tubes with diameter up to 1 ½” are marked with label on the bundle. Tubes with larger diameter than 1 ½” are implemented according to directives or upon request.

API 5L X70 PSL2 Pipe – surface protection

Line pipes are supplied without temporary protection against corrosion. Upon request it is possible to deliver tubes with agreed upon anticorrosion protection. The tube ends may be enclosed by a plastic plug.
