T-110 & Positioning Table

T-DRILL T-110 Positioning Table with a Lifting Table

T-110 measuring table is used for controlled and precisely dimensioned transfers of pipes in the angle and axial directions. Using the measuring table it is possible to estimate accurately both the distance as well as the angle gap between two collars (or the start-off point and the collar). The measuring table is suitable for pipe sizes Ø28…Ø219.1 mm. The maximum length of the pipe is 3000 or 6000 mm.

T-110 will be lifted and moved down with help of a lifting table. The lifting table will be bolted to the floor and T-110 is fastened to the lifting table.

There are two standard lengths available: 3000 mm and 6000 mm.

Technical information

Ball pull package

The ball pull tool is used for collaring a pipe, to which the normal collaring
method is not applicable. Each ball is valid only for one collar dimension.

1. Does T-DRILL have ped (pressure equipment directive) approval?

The extruded pipe branches manufactured with T-DRILL collaring machines meet the requirements of Pressure Equipment Directive (PED) 97/23/EC Annex I section 3.1.1.

The assessment is based on tests and research reports performed by T-DRILL Oy and several independent research organisations since 1980's and supported by long-term experience. Extruded pipe branches manufactured in accordance with the operating instructions of the machine will not contain defects detrimental to the safety of pressure equipment.

In the extrusion process the wall thickness will be reduced. The material will also be strain-hardened as specified in the operating instructions of the machine. The pressure equipment manufacturer shall observe this strain-hardening when designing the branch, and heat treatment of the part may be required.

2. What about wall thinning?

Short Answer : As in any extrusion process, there is wall thinning. It amounts to only 7-12% in the critical saddle point area. For reducing outlets, the actual wall thickness at any point is more than the critical wall thickness and often equal to or larger than the branch pipe wall.

Long Answer: Analysis for ASME Boiler and Pressure Vessel Code has proven that the most critical area in an extruded outlet is the saddle point. As mentioned above, thinning in the saddle point is only 7-12%. The wall thickness in the stirrup (sidewall) area can be 50% less than the wall thickness in the saddle point and still withstand the same load. In actual practice the limit is fixed usually at 35% by most fitting manufacturers. Even with the worst case scenario, size on size outlets, the maximum wall thinning by the T-DRILL process is less than 35% in the stirrup area. Therefore, wall thinning has an insignificant influence on the strength of the connection.

3. Have burst pressure tests been done?

Yes. We have calculated the allowed pressure using ASME B31.3 for outlets in both schedule 5S and 10S stainless steel. Independent testing done by various US and European companies yield results that verify these calculations: The actual burst pressure is between 6 and 8 times the calculated allowed pressure and usually the same as the undeformed pipe!

4. What about work hardening?

There is some degree of work hardening that occurs during the cold forming of a collar. The degree depends on the size of the collar relative to the size of the run pipe. Work hardening serves to increase the strength of the collar and is comparable to what occurs during pipe bending.

5. How does the T-DRILL process affect the corrosion resistance of stainless steel?

As long as the tooling is in good shape and proper lubrication is used, the effect on the corrosion resistance of low carbon stainless steel is negligible. In general, there will be more corrosion/erosion problems resulting from the welded area (of which there are three when using pipe fittings) than the extruded area.

6. What are the flow characteristics of an extruded outlet?

The flow properties in an extruded outlet are similar to those of a standard tee fitting and superior to those produced by nozzle welding. No sharp corners exist to induce turbulence. It is possible to adjust the ID of the outlet to match the ID of the branch pipe, even better than what is possible with a standard tee fitting, thus minimizing turbulence/erosion at the weld site. Note: Most pipe system failures occur at weld sites and the use of T-DRILL minimizes the number of weld sites.

7. What wall thickness pipe can T-DRILL equipment work on?

Please see the capabliity chart of the machine (in the brochure and in 'Technical information'). There is the detailed information about the wall thicknesses of the machine. The same wall thicknesses can be applied to carbon steel, too.

Back

8. How high a collar can be produced?

Depends on the material and the relative size of the branch opening to the run pipe. In general, the collar height is the propotion of the branch pipe to the run pipe multiplied by 0.05 - 0.1. Please see the table below:

Back

9. How close together can outlets be put?

Depends on the machine and the outlet size. In general, the first outlet centerline can be 1-1/2 times the outlet diameter from the end of the pipe and the outlets can be spaced centerline-centerline approximately 1-1/2 diameters apart as the minimum. Depends some on the clamp width.
Back

10. Can outlets be produced that are consistent in height?

Yes. All machines have a setting that maintains the faced collar height at an operator determined point.
Back

11. What is the smallest and largest outlet that can be formed?

In general, outlets from 19 mm OD up to 219.1 mm can be formed. However, the largest outlet produced to date has been 850 mm.
