Our optimised clamps for the 16 mm HISWeld welding table system are the perfect helpers for secure and precise clamping of your workpieces. Whether pipe clamps at 45°, 90° oder 180° - they offer flexible positioning and a powerful hold, precisely matched to the 16 mm hole pattern.
Thanks to their simple adjustability and stable fixation, they ensure efficient work during welding, assembly and clamping work. Ergonomically optimised handles enable comfortable handling and quick adjustments. Thanks to the optimised and reinforced round tube, you can dismantle our clamps and use them in all system drill holes. There are therefore no limits to their application and they can be used universally, e.g. for stop and support angles etc. Furthermore, they do not cause any interfering contours in your application.
Product features and advantages of our clamps:
- Quick and easy adjustment: The horizontal round tube allows the clamp to be adjusted quickly, while the vertical round tube with a length of 200 mm ensures precise positioning.
- Secure fixing: An adjusting ring reliably fixes the vertical tube in the system holes for a stable hold during work.
- Versatile angle of inclination: Our pipe clamps are available in 45°, 90° and 180° inclinations for powerful clamping of components at precisely the desired angle.
- Robust design: All models have a 25 mm diameter disc head (cross) that optimally transfers the force to the workpiece.
- Flexibility through rotatability: The 90° pipe clamp can be rotated continuously through 360°, allowing free positioning. In addition, the 45° and 180° pipe clamps can be completely dismantled and can therefore be used optimally in all system bores of the tools.
Pipe clamps are among the most important clamping tools in professional metalworking and welding technology. They enable workpieces to be fixed quickly, flexibly and securely directly to the welding table. Thanks to the robust round tube, the clamps are particularly easy to adjust horizontally, while the vertical round tube (200 mm long) ensures a stable clamping position. It is reliably fixed in the system holes via an adjusting ring. This makes pipe clamps ideal for precise clamping solutions - from delicate work to complex welded constructions.
New from Q4/2025: Our new pipe clamps are equipped with an optimised 2K-ERGO handle, which ensures even greater ergonomics, comfort and precise clamping force - perfect for professional use in metalworking, welding technology and everyday workshop work.

Pipe clamp 180°
Item no. HIS16Z3000
The 180° pipe clamps enables components to be clamped precisely and powerfully at a 180° angle to the system bore. The round tube allows the clamp to be adjusted horizontally quickly and easily. The vertical round tube has a length of 200 mm. A set collar is used to fix the vertical tube in the system holes.
- Width: 170 mm
- Height: 200 mm
- Spindle length: 90 mm
- Inclination: 180°
- Disc head: ø 25 mm (cross)

Pipe clamp 45°
Item no. HIS16Z3045
The pipe clamp 45° is the ideal clamping tool for precise and powerful fixing of components at a 45° angle to the system bore. Thanks to the sturdy round tube, the clamp can be quickly and flexibly adjusted horizontally, while the vertical round tube with a length of 200 mm ensures a secure hold. An adjusting ring reliably fixes the vertical tube in the system holes of the welding table, ensuring maximum stability when working.
- Width: 170 mm
- Height: 200 mm
- Spindle length: 90 mm
- Inclination: 45°
- Disc head: ø 25 mm (cross)

Pipe clamp 90°
Item no. HIS16Z3090
The 90° pipe clamp enables components to be clamped precisely and powerfully at a 90° angle to the system bore.
The clamp can be rotated continuously through 360° and can therefore be positioned freely. The vertical round tube has a length of 200 mm. A set collar is used to fix the vertical tube in the system holes.
- Width: follows
- Height: 200 mm
- Spindle length: 90 mm
- Inclination: 90°
- Disc head: ø 25 mm (cross)
New design. More ergonomic. Significantly stronger clamps.
Pipe clamps for 16 mm and 28 mm systems - now with optimised stability and maximum precision

Our pipe clamps in the 16 mm and 28 mm system will have a completely revised design from Q4/2025. The new 2K-ERGO handle ensures greater ergonomics, maximum ease of use and precise clamping force - even during intensive use.
All models have been standardised as part of the relaunch and will be available in a consistent design in future. The optimised handle shape enables safe handling, while the integrated hexagon socket ensures powerful clamping and releasing.
Another quality feature is the reinforced tube thickness: it increases the stability of the clamps and makes them even more resistant to the highest loads. This makes the pipe screw clamps ideal for professional use.
Particularly practical: the clamps are height-adjustable and can therefore be used flexibly in both the 16 mm and 28 mm systems.
In our gallery you will find an overview of all the latest new products and design updates for pipe clamps.
During development and production, we place the highest value on quality, stability and durability. The material thickness used is designed to easily compete with any premium supplier on the market - for maximum reliability in metal processing, welding technology and workshops.
