REPORTS
At American Steel Pipe, all reports are computer generated and available following final shipment. Your sales representative will be happy to discuss any of these reports in more detail with you. Reports available on Line Pipe manufactured to API 5L specifications:
- Chemical analyses
- Mechanical property tests
- Fracture toughness tests
- Data regarding skelp properties
- SR-15
- Additional specific tests as requested by customer
HYDROTEST
Line Pipe is hydrotested to at least 85 percent of the specified minimum yield strength (SMYS) for 18" or smaller diameter pipe, and 90 percent of the SMYS for 20" diameter pipe and larger. Pipe is tested with the weld line facing up, and the trained HydroTest operator inspects the entire line of pipe for defects.
ULTRASONIC INSPECTION
American Steel Pipe provides our primary nondestructive quality assurance through the ultrasonic evaluation of the weld and heat affected zone of each pipe.
Certified Training
The performance of the equipment and the application of this procedure is the responsibility of personnel qualified at ASNT-TC-1A, Level III. All additional American personnel who perform this testing are certified to ASNT-TC-1A, Level II.
