API 5L X65 PSL1 Pipe – delivery condition and surface

Usually, API 5L X65 PSL1 pipes are supplied as hot rolled. Only tubes with DN 6 -10, perhaps tubes of other dimensions are supplied as cold drawn and after forming they are heat treated. This is done as per the previous agreement. The tube surface meets corresponds to the means of manufacturing.

API 5L X65 PSL1 Pipe – straightness

Tubes are visually straight.

Ends of the API 5L X65 PSL1 Pipe

The ends of the 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 X65 PSL1 Pipe and tube bundles

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

API 5L X65 PSL1 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.
