Split-frame cold cutting
Clamshell machines mount around the pipe in place and cut through the wall without heat, sparks or distortion, even where access is tight.
Pipe cold cutting services in Saudi Arabia for live plants, shutdowns and project sites. Our crews cut and bevel pipe on site with split-frame machines, so there is no flame, no sparks and no heat-affected zone, and the pipe end comes off the machine ready for welding.
Pipe cold cutting
Cutting pipe with a grinder or torch in an operating facility means hot work, fire watch and a long permit process. Cold cutting removes the flame and the sparks from the job. A split-frame (clamshell) machine clamps around the pipe and a slow-turning tool bit machines through the wall, so the cut stays cool and the surrounding plant stays safe.
The same set-up cuts and bevels in one pass. Instead of a rough cut that still needs grinding, you get a square, clean end with the bevel your welding procedure calls for, which shortens fit-up and improves weld quality on tie-ins and modifications.
We use pneumatic or hydraulic drives so the machines can work in classified areas, and we plan each cut with your operations and safety teams. Our pipe cold cutting services in Saudi Arabia also include diamond wire and saw cutting for large-diameter or thick-walled lines, and for cutting through vessels and structures.
Cold cutting is usually one step in a larger job. Once new spools are welded in, we can prove them with hydrotesting, dry and inert them with nitrogen purging, and make up the flanged joints with bolt torquing.
What we offer
One mobilisation covers cutting, bevelling and end preparation, so the line is ready for the welders as soon as we leave.
Clamshell machines mount around the pipe in place and cut through the wall without heat, sparks or distortion, even where access is tight.
Standard and compound bevels, J-preps and land machined to your welding procedure in the same set-up as the cut.
Internal counterbores and square end faces so mismatched wall thicknesses fit up correctly for welding.
For large-diameter, thick-walled and multi-layer sections, and for cutting vessels and structures during decommissioning.
Air or hydraulic drives with no electrical ignition source, planned with your permit-to-work and gas-testing requirements.
Carbon steel, stainless, duplex, alloy and clad pipe, with tooling, speeds and coolant chosen for each material.
How we work
We check pipe size, wall thickness, material, access and clearances, and agree cut locations and bevel details with your engineers.
The line is isolated, drained and gas-tested under your permit-to-work before any machine is mounted.
The split-frame machine is clamped around the pipe and trued so the cut is square to the pipe axis.
The tool bits feed through the wall slowly and cool, cutting and bevelling the pipe end in one operation.
Bevel angle, land and end squareness are checked, the ends are protected, and the area is handed back clean.
Standards and safety
Our pipe cold cutting services in Saudi Arabia follow the same safety and quality controls on every job.

Our bolting crews mobilize with calibrated equipment across Saudi Arabia, 24 hours a day.
FAQ
Cold cutting is a machining method that cuts through pipe with a slowly rotating tool bit instead of a flame or abrasive disc. Because it produces no sparks and very little heat, it can be used in and around operating plant where hot work is restricted.
The cutting itself produces no flame or sparks, so many sites treat it as cold work. The permit type is always decided by your site's permit-to-work system, and the line must still be isolated and gas-tested.
Yes. The split-frame machine can cut and bevel in one set-up, leaving a weld-ready end with the bevel angle and land required by your welding procedure.
