Online Intelligent Pipe Inspection System

Fitted at the end of the extruder, pipe moves automatically to the inspection platform for laser thickness, encoder diameter and ovality checks with pass-flipping — without interrupting the line — and results go to MES, Kanban or other systems.

What is it

Overview

The Sealion online intelligent pipe inspection system is fitted at the end of the extruder and can be installed at the end of any line; pipe moves automatically to the inspection platform for measurement, without affecting any production task.

It includes laser thickness measurement, encoder diameter measurement, non-roundness detection and qualified-pipe flipping as standard. All test data can be sent to the factory's internal MES system, a production Kanban, or another management system for remote quality monitoring.

Functions

Functional characteristics

Thickness measurement: upper/lower wall-thickness limits and real-time wall thickness are set; a patented structure lasers the pipe from inside and out while a servo motor rotates one full turn, computing accurate thickness in every direction and marking the max/min positions. The detection point sits 30–50mm from the pipe end to avoid the flared cut edge, and the laser avoids direct reflection off the pipe surface.

OD measurement: the average OD of the off-line pipe is measured, with average upper/lower limits set; an encoder rotates one full turn to compute the accurate OD, at a detection point 300mm from the pipe end, meeting national standards.

Ovality (non-roundness): two sets of lasers measure OD at several points to calculate and display non-roundness.

Ellipticity: pipe ovality is calculated from the measured wall thickness and displayed on the interface.

Data storage and collection: all data saved in real time as Excel; TCP or MQTT ports open for upload to the company MES or a customer-specified port; export by order or date in Excel or PDF.

Data display: real-time display of current production quantity, yield, NG count and OK count.

Alarm function: a defective-product alarm and a quantity-reached reminder.

Data processing: abnormal data is excluded and not linked to the traceability code.

Manual checks that are slow, that miss, and that leave no data behind — this is what we solve daily.
