Before machining
• Perpendicularity and ovality defects
• Roughness and burrs incompatible with proper welding preparation
• Risk of pe*******on defects and lack of fusion

After PROTEM beveling
• Bevel machined to specified angle and geometry (single, compound, narrow gap)
• Homogeneous and repeatable surface finish
• Preparation compliant with welding requirements

PROTEM beveling solutions guarantee precise and reproducible preparation of your tubes, directly contributing to the metallurgical quality of the weld and reducing non-conformities on site or in the workshop.

The SERCO XP600NG is a compact and versatile portable lathe designed for on-site operations such as surfacing, boring, counterboring, conical machining, and machining of RTJ grooves.
With a minimum height of 250 mm (9.8"), the XP600NG can be positioned between two fl**ges to machine sealing surfaces directly on site. Its reduced weight allows single-operator handling, without additional lifting devices.

Two configurations are available:
• 4-arm version – Positioning in dowel pin bores (sealing surfaces only)
• 4-arm version + FSTG500 – positioning through the back face of the fl**ge (seal surface and bolt working surface machining)
These options make the XP600NG ideal for maintenance and repair of fl**ges with diameters from 10 to 600 mm (23.6").

✅ Quick set-up
✅ Light weight
✅ Mobile
✅ Easy and safe for the operator
✅ Reliable and versatile
✅ High accuracy
✅ Designed for tight spaces
✅ Cold machining

Designed for restrictive environments and very tight spaces, the XP machines feature independent parallelism and concentricity adjustments. Only two steps are required, and once in position, the machine can be adjusted with ease to achieve 0.01 mm accuracy.
SERCO engineers and operators support preventive and corrective maintenance on fl**ges, valves, sealing surfaces, engine blocks and more, directly at customer sites.
