API 5L 3.2 Certified Pipe

Under this specification, the grades covered are A25, A, B. The following “X” grades are also covered: X42, X46, X52, X56, X60, X65, X70, X80. The two digits following “X” signify the Minimum Yield Strength of the pipe that has been produced in this grade.

We, at Trio Steel, stock the complete range of pipes in both PSL1 and PSL2 in seamless.

Other details:

Surface
1. All surfaces have been 100% visually inspected. The surface condition complies with API 5L standards.
2. 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 standards:
1. longitudinal: 100% of the pipe surface
2. pipe ends not scanned by automatic ultrasonic system shall be inspected by manual UT or Magnetic Particle Examination.

Certification and traceability
All dimensions will be supplied with a 3.2 certificate according to EN 10204, endorsed by recognized and independent inspection agency. Marking shall be in SI units (X52) accordance with API requirements & mill standard.

Dimensional control
All dimensions will be supplied according to API 5L clause 9.11; In addition, the following tolerances apply:
1. Pipe body: +/- 0,75%
2. Pipe end: +/- 0,5%
3. Wall thickness: +15%, -12,5%
4. Length: -0 / +100mm

Pipe Ends

Pipe Ends are bevelled. End angle shall be 30°- 0°/+5°, root face shall be 1.6mm +/- 0.8mm and fitted with bevel protectors.

Protection

Pipes are varnished on the outside.
