Metal Pipe Inspection

Applicable materials: Suitable for various metal pipes such as carbon steel, low-alloy steel, alloy steel, stainless steel, duplex steel, aluminum alloy, copper alloy, titanium alloy, nickel based alloy, etc.

Applicable products: including seamless steel pipes, welded steel pipes, boiler pipes, pressure vessel pipes, fluid transport pipes, structural pipes, heat exchange pipes, petroleum casings, pipe fittings, and pipeline accessories.

Applicable scenarios: Used for incoming inspection of pipe raw materials, factory quality acceptance, engineering completion acceptance, regular inspection of in-service pipelines, process performance evaluation, failure analysis, and quality arbitration testing.

Chemical composition analysis: determination of the content of carbon, silicon, manganese, sulfur, phosphorus, chromium, nickel, molybdenum, copper, titanium, vanadium and other elements, and determination of the conformity between material grade and composition.
Mechanical performance testing: room temperature tensile, yield strength, tensile strength, elongation at break, high temperature tensile, impact toughness, Rockwell/Brinell/Vickers hardness, bending performance testing.
Process performance testing: flattening test, expansion test, curling test, bending test, hydraulic test, pneumatic test, sealing test.
Metallographic examination: examination of microstructure, grain size, non-metallic inclusions, decarburization layer, banded structure, weld and heat affected zone structure.
Non destructive testing: ultrasonic testing, eddy current testing, X-ray testing, magnetic particle testing, penetrant testing, used for surface, near surface, and internal defect detection.
Size and appearance inspection: outer diameter, inner diameter, wall thickness, length, ellipticity, straightness, end face perpendicularity, wall thickness unevenness, and size tolerance evaluation.
Surface quality inspection: Inspection of surface cracks, folds, hairlines, scratches, rust, pitting, oxide scale, weld formation, and appearance defects.
Corrosion performance testing: intergranular corrosion, pitting corrosion, stress corrosion, uniform corrosion, salt spray corrosion performance testing.
Failure analysis: Analysis of failure modes and causes such as pipe fracture, corrosion, leakage, wear, and deformation.
