Mechanical Gauging Of Reformer Tubes

We are trying to locate a company that makes mechanical ID gauging tools for 4" typical reformer tubes. We believe there was a company in Machester Uk who made such tools does anyone know a contact name, address etc.

Regards

Re: Mechanical Gauging Of Reformer Tubes
Dear John,

SUBJECT: Internal Bore Inspection of REFORMER TUBES

QUEST currently applies our “laser based” inspection technology (LOTIS) to gauge internal bores of reformer tubes in many countries around the world. In addition to regular “preventative maintenance” inspections, QUEST has applied the LOTIS technology to perform “base line” exams both while tubes are vertically hanging in the harp and while still in the horizontal position at the tube mill before shipping to the customers plant site.

LOTIS gathers approximately 2.2 million readings over the full length in only a few minutes per tube. During “base line” exams, flaws such as a) Over Dimensional Boring, b) Under Dimensional Boring, c) Weld Root Pass Lack Of Penetration (LOP), d) Suck Back at the Weld Root Pass, e) Too Large Root Pass Hanging Into Tube, f) Start/Stop Boring Gouges, g) etc. can be easily identified. Applying this “LASER” technique has the advantages of extreme high resolution and accuracy.

QUEST has designed custom software designed specifically for reformer tube inspection, which allows the customer to view the “whole” reformer tube network or “individual” tubes in 3-Dimensional (3D) format. This information is used by plant engineers to assist in balancing the reformer to reduce concentrated damage.

For more information on QUEST’S LOTIS technology please visit our web site located at http://www.qi2.com/field/fsddef.htm -or- give me a call at 1-253-872-1275.

...
s. This projector incorporates design and safety features that make it flexible, compact and lightweight. The Projector is lighter than most of its competitors. It incorporates an improved source channel, based on a new helicoidal design, which makes maintenance easier. The helicoidal design also allows smoother movement of the source assembly inside the device, making it easier for the operator and improving safety. The Projector also has a unique safety feature not found in competitive products. The source assembly locking mechanism is triggered by the source holder capsule at the front of the source assembly, thereby always assuring the operator that the source has returned to the safe position. The Exertus Dual 120 is ISO3999:2004 compliant.
