Nondestructive Inspection

Nondestructive Inspection

Nondestructive inspection is an integral part of pipe production.Nondestructive testing (NDT) uses methods like X-ray or ultrasound to detect defects without damaging the material. For welded pipes with steel grade ≥L210/A and diameter ≥60.3 mm, 100% NDT is required on welds and strip/plate butt joints in SSAW pipes.

Ultrasonic Inspection

Every plate is ultrasonically checked for its internal soundness in accordance with customer's specification or mill's standard. This device can inspect the whole volume of the plate at high sensitivity.

Ultrasonic Inspection of Weld Seam

Baowi steel uses the ultrasonic and radiographic methods for nondestructive inspection of submerged arc welded seams. Shown below are probe arrangement. This is capable of dectecting longitudinal and transverse imperfections.

X-Ray Inspection of Weld Seam

Any portion showing substandard indications in ultrasonic inspection is double checked with radiographic equipment.

Magnetic Particle Inspection

Magnetic Particle Inspection

Pipe end (bevel surface and weld seam) are magnetiezed and provided with magnetic particles.

Eddy Current Inspection

A coil in test coil assembly induces an eddy current around the circumference of the pipe as it passes through the assembly. Flaws disturb eddy current and are thus sensed by a pick-up coil in assembly.

Electromagnetic Inspection

Electromagnetic Inspection

Plug mill is equipped with an Amalog-Sonoscope, electromagnetic inspection units after heat treatment.The Amalog-Sonoscope pipe inspection system detects defects by using flux leakage by electromagnetic induction in search coil.

Magnetic Particle Inspection

The tube is magnetized and provided with magnetic particles (mostly fluorescent magnetic particle). The presence of flaws creates a magnetic flux which shows changes in fluorescent brilliance under black light. The change is detected visually.
