Jireh ROTIX – High Temperature Weld Frame Scanner

High Temperature operation up to 350°C

Part # NMCEG036 Categories ,

Perform UT scans while pipes and tubes remain on-line with surface temperatures up to 350°C (662°F). The ROTIX – High Temperature Weld Frame Scanner provides encoded feedback for up to 4 probes on pipe sizes as large as 96.5 cm (38 in).

Overhead Adjustable Link

Raise the overhead adjustable link to provide space for larger probes to operate. Lower the overhead adjustable link when low-profile scanning is required.

Cable Management

High temperature cable management protects cables, tubes and hoses from contact with hot surfaces.

Adjustable Chain

Using two link lengths and an adjustable buckle, pipes and tubes ranging from 10.2 cm – 96.5 cm (4 in – 38 in) diameter may be scanned with ease. The quick release links are designed for efficient and straightforward chain setup.

High Temperature Encoder

Track the scanner movement with confidence. The heat of the scan surface dissipates across the oversized encoder wheel; this protects the components of the precision encoder which is compatible with all industry standard instruments.


Handles are available to assist with scanner control.

Slip Joint Probe Holders

Easily adjust probe centre spacing and probe alignment with these probe holders designed to accommodate most major TOFD wedge brands.

High Temperature Double Wheel Chain

The chain links have been designed to minimize heat transfer through minimal contact with the heated surface and stainless steel materials. Double wheel chains straddle the weld which alleviates scanner wandering and reduces scanner width.

Modular Design

Expand the capabilities of your scanner. Purchase magnetic wheels to convert this ROTIX system into a magnetic STIX system. (Conversion of the high temperature ROTIX decreases high temperature capabilities to 50°C (122°F))

Cable Clips

Route and organize encoder cables.


JIREH products are backed by a 3-year warranty.

Component Identification


1 Buckle

The buckle connects to the catch link to form the chain system which mounts the scanner to the inspection surface.

2 Long Link

Equivalent to (approx.) 3 short links, the long link is useful during large diameter scan setups.

3 Overhead adjustable link

The overhead adjustable link adjusts to accommodate oversized probes. When low profile scanning is required, the link may be contracted.

4 Slip joint probe holders

Two, TOFD (time-of-flight diffraction) probe holders carry all standard probes and wedges.

5 Handles

Handles allow a grip point for the scanner as well as a mounting point for various accessories.

6 Short Link

Multiple short links complete the chain configuration around pipes and tubes.

7 Short link with dovetail

Utilize the dovetail mount to add accessories to the scanner such as cable management.

8 Catch Link

The catch link completes the chain connection around the scan surface. Use the dovetail mount to carry accessories when required.

9 High Temperature Encoder

This spring-loaded encoder maintains constant contact pressure with the scan surface. Position the encoder where convenient along the frame bar and connect to any standard instrumentation.
