Industrial tubing and process piping prefabrication
In process piping prefabrication, cost and lead time often depend on the number of outlets, flanges, welds, setups and inspections. TARGA assesses drawings and current processes in Poland, selecting T-DRILL technologies where they can simplify the manufacture of manifolds, spools, skids and other piping assemblies.

Process piping: where do prefabrication costs arise?
The tube length is only one part of the fabrication process. Time and cost increase with the number of outlets, flanged ends, welds, positioning operations and quality inspections. For manifolds, spools and skids, it is therefore useful to assess the complete manufacturing process.
Fittings, tees and joint preparation
Each additional outlet may require a separate component, fitting, welding and inspection. In a suitable application, collaring forms the outlet neck directly from the run tube.
Flanges and welding operations
For some end connections, flanging can replace welding on a weld-neck flange by forming a flange directly from the tube end.
Time, inspection and rework
More separate components mean more joining and inspection operations. T-DRILL also offers automated internal welding with T-InWeld for selected series-production applications.
Repeatability along long components
Where many outlets are formed in sequence, stable positioning, operation order and reduced operator variation are as important as forming itself.
How does T-DRILL technology fit into process piping prefabrication?
Each installation has different needs. We start with the assembly drawing and current process, then assess which operations are worth changing.
Tube collaring
An outlet neck formed directly from the run tube. A process to assess for manifolds and components with multiple repeatable outlets.
FLANGINGTube flanging
Forming a flange on the tube end instead of welding on a separate weld-neck flange, where the connection requirements allow it.
T-INWELDInternal welding
Automated internal welding for selected series-produced tube components where repeatability and internal surface quality are key.
APS / AUTOMATIONPositioning and integration
For long manifolds and multiple operations, automatic positioning and integration of subsequent process stages can be assessed.
Collaring, flanging and welding in one assembly
A spool or manifold may include outlets, flanged ends and welded joints. T-DRILL develops dedicated technologies for these operations, which can be assessed together as part of the production flow.
1. Drawing and current process
We list the components, outlets, flanges, welds and preparation operations.
2. Operation assessment
We assess which outlets can be formed, which ends can be flanged and where welding remains necessary.
3. Technology selection
We select the machine, tooling and any positioning system for the actual production mix.
4. Trials and process economics
Where needed, we verify the workpiece using customer material and compare time, operation count and process cost.
A Polish example: KOFAMA/ZARMEN prefabrication
The published T-DRILL KOFAMA/ZARMEN case study combines an F-420e HOT flanging machine, a TEC-220 collaring machine and a 12-metre APS positioning system. The manufacturer reports up to 80% less welding on this particular line, depending on the project. The result is specific to this installation and should not be assumed for other applications.

View the KOFAMA/ZARMEN projectWhen is it worth reviewing your prefabrication process?
- when manifolds, spools or skids with similar geometry recur;
- when an assembly includes many tees, outlets or flanged ends;
- when preparation, welding and inspection account for a large share of cost;
- when stocking multiple fitting and flange variants complicates production;
- when repeatability, cycle time and future automation matter;
- when a drawing and realistic production volume are available for comparison.
What should you send for assessment?
- drawing of the assembly, spool, manifold or piping section;
- material and tube standard;
- diameters and wall thicknesses;
- number and diameters of outlets;
- end configurations and flanged connections;
- current manufacturing method and approximate weld count;
- quality, design or acceptance requirements;
- annual volume, batch size and workpiece mix.
Have a piping drawing ready?
Send a section of your current design. We will assess which operations are worth comparing with T-DRILL technologies and whether trials are needed.
FAQ
What does “process piping” mean here?
Here, the term covers piping and prefabricated assemblies serving an industrial process, where material, geometry, joint quality and specific project requirements matter.
Does T-DRILL eliminate every weld in an installation?
No. Individual technologies may reduce separate fittings or selected welding operations, but the scope depends on the geometry and requirements of the assembly.
Can collaring and flanging be used in the same process?
Yes, where the workpiece includes outlets and suitable flanged ends. Each operation must be assessed separately for the material, dimensions and project requirements.
Can a particular spool or manifold be verified before investment?
Yes. Start with the drawing, material, dimensions, current manufacturing method and volume. These allow us to decide whether trials are needed.
