PSL refers to the product specification level where PSL2 provides a more extensive chemical composition complete with a mandatory minimum fracture toughness.
Surface
(a) All surfaces have been 100% visually inspected. The surface condition complies with API 5L Annex E . (b) External surface of pipe shall be coated with a layer of varnish.
NDT
All pipes will be ultrasonic tested on pipe body and pipe end as per API 5L Annex E, Table E.2 and para E.3.3. Coverage:
(a) longitudinal: 100% of the pipe surface
(b) pipe ends not scanned by automatic ultrasonic system shall be inspected by manual UT or Magnetic Particle Examination.
Hydrostatic test
(a) Test pressure may not exceed 2970 psi in accordance to API 5L requirements (b) Holding time: minimum 5 seconds
Certifcation and traceability
