On-Site Flange Facing
On-Site & In-Situ Flange Facing
Nicol & Andrew repair worn or damaged flanges using our in-situ flange facing equipment. We will provide any surface finish you require including “Gramophone”. We can also grind the face to give a very fine finish if needed.

Will Our Equipment Mount On Your Flange?
We mount our machines in the existing bore (from 25mm up to 3m diameter) using mandrels or rigid extending legs, or on the outside diameter if the bore is not suitable. Almost all flange types are suitable for in-situ repair.
Types of Flange Face Suitable For Repair
Our standard machines cover all main types of flange face including:
- Raised Face
- Flat Face
- Ring Type Joint (RTJ)
Machining across bolt holes is performed with virtually no reduction in the flatness or surface finish achieved.
Types of Surface Finish Produced
The industry standard for raised and flat faces is phonographic serrated. The facing finish is judged by visual comparison with Roughness Average (Ra) standards or by portable electronic surface roughness gauges.
The standard Ra supplied by the industry is 125 to 250 µ inch or 3.2 to 6.3 µm. Smoother or rougher finishes are available at the customer’s request.
Hydraulic Tensioning and Bolt Removal
We offer a full range of stud tensioning and torque equipment for hire. This includes “Nut Splitters” and all the ancillary tools required.
