Is the Pipe bender 8 Ã· 22 mm, type M 22 suitable for use in a standard bench vise and what vise throat size is required?

Yes. The Pipe bender 8 Ã· 22 mm, type M 22 is designed for mounting in a vise, so it is suitable for use in a standard bench vise. Because the unit weighs 14 kg and is built as a lightweight yet robust bending device, you need a vise with sufficient throat depth and secure clamping capacity to hold the tool and absorb bending forces without movement. Recommended vise throat size: minimum 80â100 mm (3.1â3.9 in) to allow the pipe bender body and its rollers to sit fully and be clamped safely. Also ensure the vise jaws provide a firm, wide grip (jaw face width at least 50â80 mm) and that the vise is solidly mounted to the bench to handle the 14 kg tool and bending loads.

Can Pipe bender 8 Ã· 22 mm, type M 22 be used for precision bends on stainless steel tubing and what limitations apply?

Yes - the Pipe bender 8 Ã· 22 mm, type M 22 can be used for precision bends on stainless steel tubing, but with limitations. Its angle-value scales on the rollers help achieve repeatable, measured bends; mounting in a vise and the durable metal construction (14 kg) provide stability for controlled work. Limitations: intended tube diameters are 8â22 mm only; thicker-walled or larger-diameter stainless tubing may exceed the toolâs capacity or springback tolerance. Stainless steelâs higher springback means bends may require overbending or secondary adjustment; very tight radii risk kinking without internal support or mandrels (not included). For highest precision on thin-wall stainless, use careful setup, appropriate roller radii, and consider mandrels or a hydraulic bender for repeatable, distortion-free results.

How do I maintain and calibrate the angle scales on the Pipe bender 8 Ã· 22 mm, type M 22 for long-term accuracy?

To maintain and calibrate the angle scales on the Pipe bender 8 Ã· 22 mm, type M 22 for long-term accuracy, follow these steps: 1. Regular inspection - Before each use, visually check the angle scales on the rollers for wear, dirt or paint that could obscure markings. - Ensure rollers rotate freely and larger rollers sit correctly over smaller ones without lateral play that could shift scale alignment. 2. Cleaning and lubrication - Clean scales with a soft brush and a dry or lightly oiled cloth to remove debris; avoid aggressive solvents that could damage markings. - Lightly lubricate bearings and moving joints per manufacturer recommendations to prevent slop; do not apply lubricant to scale faces. 3. Mechanical check and tightening - Verify all mounting bolts, pins and fasteners that hold the rollers and scale plates are tight. Loose fasteners cause scale drift. - Check the vise mounting: the Pipe bender 8 Ã· 22 mm, type M 22 must be rigidly clamped. Any movement in the vise affects angle accuracy. 4. Calibration procedure - Select a straight reference pipe of known diameter within the tool range and a reliable protractor or digital angle gauge. - Mount the tool in the vise and set the roller to the zero position (unbent). Confirm the scale reads zero against your angle gauge. - Make a controlled bend to a common angle (e.g., 45Â°) using the toolâs scale. Immediately measure the actual angle on the bent pipe with the protractor/gauge. - Compare the measured angle to the scale reading. If the discrepancy exceeds acceptable tolerance (decide a tolerance, e.g., Â±1Â°), adjust the scale: - Loosen the screws or clamp that secure the scale plate or roller position. - Rotate or shift the scale plate until the scale reading matches the measured angle. - Retighten fasteners and recheck at several angles (e.g., 15Â°, 30Â°, 45Â°, 90Â°) to ensure linear accuracy across the range. 5. Repeatability test - Perform multiple identical bends and measure each to confirm consistency. If variability appears, inspect for worn rollers or play in pivot points and replace worn parts. 6. Documentation and schedule - Record calibration results and any adjustments. Establish a periodic check schedule based on usage: heavy daily useâweekly checks; occasional useâmonthly or before important jobs. 7. Replacement and service - If scale markings are worn beyond legibility or mechanical wear prevents accurate adjustment, replace the affected rollers or scale plates. Use only compatible parts for the Pipe bender 8 Ã· 22 mm, type M 22. Following these steps will keep the Pipe bender 8 Ã· 22 mm, type M 22âs angle scales accurate and reliable over time.
