TUBESEAL H89

One Tube at a Time — Every Tube the Same

A heat exchanger or boiler tubesheet can carry hundreds of tube-to-tubesheet joints, and every one has to seal. Welded by hand, the welder walks the torch round each tube end, and the result changes with fatigue, access and torch angle. The TubeSeal H89 takes the hand out of the circle.

The head locks inside the tube on an expanding tensioning block, the torch is set once on its X-Y slide and angle fixture, and a stepper motor carries it round the joint at the speed and through the angle set on the controller. Pause, resume, stop and return to zero are one touch away.

TUBESEAL H89

From Tube to Tube in Six Steps

1Fit the block

Measure the tube ID and fit the tensioning block that covers it.

2Insert and lock

Push the head in until the positioning block sits on the tubesheet; turn the locking nut right.

3Aim the torch

Set the torch angle (±90°) and its X / Y position (±60 mm) on the joint.

4Set zero

On the Manual screen, jog to the start point and press Set Zero Point.

5Set the degrees

On the Parameter screen, enter the rotation angle; on the Run screen, the welding speed.

6Start

Press Start. At the end the torch stops and returns to zero. Unlock, lift out, next tube.

Question & Answers

Screen 09 ▸ FAQ

TUBESEAL H89

Tube to Tubesheet Welding Machine — FAQs

What is the TubeSeal H89 tube to tubesheet welding machine?

A portable automatic machine that clamps inside a tube and turns a MIG/MAG torch round the tube end, so every tube-to-tubesheet joint on a boiler or heat exchanger is welded with the same path, speed and angle.

What tube sizes does it fit?

Tubes with an inner diameter of 28–76 mm. The head clamps on an internal expanding tensioning block; you fit the block whose range covers the measured tube ID.

Which welding process does it use?

CO2 gas-shielded MIG/MAG welding. It connects to your MIG/MAG power source and wire feeder; current, voltage and wire feed are set on the power source to suit your qualified procedure.

How is the torch set on the joint?

With a fine adjustment block of X ±60 mm and Y ±60 mm and a welding fixture that sets the torch angle through ±90°. A positioning block on the tubesheet face keeps the head at the same depth in every tube.

Can I set how far it turns?

Yes. The rotation angle is set freely on the touch screen — for example 180° for half a turn, 360° for one turn or 720° for two. At the end of the weld the torch returns to its zero point.

What controls does it have?

Start, Pause (press again to finish the rest of the seam), Stop, Emergency stop and Single direction on the Run screen; Forward, Reverse, Set zero point and Return to zero on the Manual screen; rotation angle and speeds on the Parameter screen.

Which joints and tubesheets can it weld?

Flat corner welds where the tube stands proud of the tubesheet, and butt welds with the tube aligned to the face — on boiler, heat-exchanger, tube-box and air pre-heater tubesheets.

How do I get the TubeSeal H89 price and delivery time?

Request a quote on this page or message +91 88008 82983 on WhatsApp with your tube ID, tube count and joint type. You will receive a GST quotation with delivery time, usually the same working day.
