API 5L X70 PSL1 Pipe – delivery condition and surface
Usually, API 5L X70 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 X70 PSL1 Pipe – straightness
Tubes are visually straight.
Ends of the API 5L X70 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 X70 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 X70 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. API X Grades – some of the sturdiest pipes and tubing available designed for extreme environments or exceedingly high-pressure environments
