Pipe Inbound Quality & Safety System
Fitted at the end of the extruder, a smooth mechanism slides each pipe onto the inspection platform for weight, laser thickness, encoder diameter, ovality and length checks — pass-only pipe is flipped through, with all data sent to MES, Kanban or other systems.
The Sealion pipe quality and safety storage system is fitted at the end of the extruder and can be installed at the end of any line, using a smooth sliding mechanism to bring the pipe to the testing platform for measurement, without affecting any production task on the line.
It includes weight detection, laser thickness measurement, encoder diameter measurement, pipe length detection, 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.
Twenty patents cover this system — 3 inventions, 15 utility models and 2 design patents. The wall-thickness measuring arrangement described above is one of them.

End-of-line quality gating and inbound storage on PE water, PE gas and PVC pipe extrusion lines.
Spot checks that miss, problems found after storage, batches that can't be traced — this is what we solve daily.
