TEE & COLLAR FORMING MACHINES

T-DRILL is a world-class supplier of tube and pipe fabrication solutions. T-DRILL machinery consists of both industrial solutions for several customer segments as well as portable solutions for mechanical contractors and plumbers.

T Drill manufactures Tee forming machines, Collaring machines, Cutting machines for Pipes, Flanging machines, Spinning machines, and various models of Portable Tee forming and Collaring machines. Apart from this, T Drill also manufactures Integrated systems with Robot cells.

As the tee is fabricated from the basic tube, no costly T-pieces are needed. Instead of three joints, there is only one joint! This saves a lot of time and means considerably lower total costs. The construction also makes the tube stronger and provides for better flow characteristics.

Pipe branching – i.e. connecting a branch pipe to a run pipe – using the T-DRILL method is also called collaring. The joint can be completed by brazing (= lap joint) or by welding (butt joint).

There are three different cutting methods available: Pull-apart, Through cut, and Cut & Break. The Pull-apart method is the most advanced cut-off method: first, the cutting disk penetrates the tube wall by approximately 95%. The cut length is then separated by pulling it apart. This eliminates or minimizes the I.D. reduction that could occur if the blade was to completely cut through the tube wall. The through cut method is the most fundamental method of cutting tubes by using rotary cutting disks. This method is used for cut lengths of 30 mm and longer by basic equipment. This method can be used in cases where some reduction in the internal diameter is acceptable. The Cut & Break method is possible when the tube piece length is under 70 mm. The blade is set to penetrate approximately 95 % through the tube wall, at which point the clamping fixture breaks the tube sideways. This method is only available on the T-DRILL TCC-50 RL Machine & Coil Tube Cutting Center.

T-DRILL Flanging Machines form a lip or flange directly on the end of the pipe allowing the use of loose flanges. This process saves up to 40 % of the time compared to traditional weld neck flange connections. The flange – also called the Van Stone and loose flange – is achieved by roll forming a flange on the end of the pipe spool. The flange can have a smooth or grooved face, depending on the forming (rolling) tool used. T-DRILL Tube End Spinners are designed to accept the requirements of a wide range of applications – including the end forming of exceptionally long or complicated tubes common in e.g. ACR, solar panels, and mechanical contracting industries. The T-DRILL Spinning Machines are fully automatic and suitable for closing, reducing, and expanding copper and brass tubes. The form of the closing can be elliptical (short closing) or spherical (round closing). Reductions and Expansions are also possible up to certain sizes.
