API 5L Line Pipe Inspection & Testing
We conduct inspections and testing throughout the production process to verify material
properties, pipe integrity, dimensional specifications, and more.
Chemical Composition Testing
We conduct chemical analysis on the pipes to verify the steel's composition and confirm compliance with the specified grade and relevant requirements.
Mechanical Testing
We can conduct tensile strength, yield strength, elongation, and impact tests as required to verify the mechanical properties of the line pipe.
Hydrostatic Testing
We conduct hydrostatic testing on line pipe to verify the pipeline's pressure-bearing integrity and to detect potential leaks or defects.
Non-Destructive Testing
We can arrange ultrasonic testing, magnetic particle testing, and other applicable non-destructive testing (NDE) methods to inspect the pipe body and welds, depending on the type of pipe and project requirements.
Dimensional & Visual Inspection
We can inspect outer diameter, wall thickness, length, straightness, end condition, surface quality, and other dimensional characteristics in accordance with applicable standards.
Weld & Surface Inspection
For welded line pipe, we inspect the welds in accordance with applicable manufacturing and inspection requirements. Prior to final delivery, the surface condition and pipe end quality are also verified.
Quality Documentation & Material Traceability
