The ROTIX - Chain Weld Scanner kit is designed to provide encoded position of probes circumferentially around piping for weld inspection on ferrous or non-ferrous inspection surfaces.

It is completely configurable for phased array, TOFD and conventional UT with single or multiple probes. Since this package includes a set of 8 magnetic wheels, this scanner can also perform inspection without the chain on ferrous materials like a standard magnetic scanner.


Adjustable Chain

Using two link lengths and an adjustable buckle, any size of pipe can be inspected from 152.4mm - 965.2mm (6in - 38in) diameter. Links are designed with quick releases to easily be added or removed.

Double Wheel Chain

A double wheel chain is used to straddle the weld. This allows the scanner frame to be centered on the weld to reduce wandering and reduce the width of the scanner.

Probe Holders

An integrated latch allows easy probe centre spacing adjustment and scanner installation. Due to its modular design most major types of phased array wedges can be accommodated.


All wheels are coated with urethane to reduce the effects of foreign debris obstructing the rolling of the scanner. Urethane also eliminates the sideways sliding of the scanner in a required position.

Brake system

A brake is provided to lock the location of the scanner in a required position.

Built in Encoder

The encoder output is fully compatible with all standard instruments.

Environmental Sealing

The scanner is sealed using O-ring gaskets and seals to protect against the penetration of contaminants into the unit.
