Is Pipe bender 6 Ã· 18 mm, type M 18 suitable for bending stainless steel hydraulic pipes without kinking?

Short answer: Possibly, but with limitations. Pipe bender 6 Ã· 18 mm, type M 18 is a very simple manual bender intended for hydraulic pipes with external diameters 6â18 mm, designed for small workshops and mounted in a vice. That means it can form bends in common hydraulic tubing sizes, but several factors determine whether you can bend stainless steel hydraulic pipes without kinking: - Material hardness: Stainless steel (especially austenitic grades like 304/316) is tougher and work-hardens more than soft copper or mild steel, so it requires more force and a proper bending method to avoid kinks. - Wall thickness and tube type: Thinâwalled stainless hydraulic tubes are more prone to collapse/kinking. Thickerâwalled or tubing specified for bending fares better. - Die/profile and support: The description mentions bending rollers, but no internal mandrel or fill. Without a mandrel or proper support, tight bends (small radii) on stainless tubing are at high risk of wrinkling or kinking. - Bending radius: Successful kinkâfree bends depend on using a sufficiently large bend radius. The toolâs rollers likely produce relatively gentle radii, but very tight bends will likely fail. - Operator technique: Slow, controlled bending and even heating (for some stainless grades) help; a heavy manual bender and skilled operator improve results. Conclusion: Pipe bender 6 Ã· 18 mm, type M 18 can be used for bending stainless steel hydraulic pipes in many common, moderateâradius applications, but it is not ideal for thinâwalled or very tight bends. For consistent, kinkâfree results on stainless tubing, especially with tight radii, use a bender with appropriate dies and internal mandrel support or a powered machine designed for stainless steel.

Can the Pipe bender 6 Ã· 18 mm, type M 18 be securely mounted in a standard workshop vice for safe bending?

Yes. The Pipe bender 6 Ã· 18 mm, type M 18 is explicitly designed for mounting in a workshop vice. Its durable metal case and 10 kg weight provide stable support during manual bending of hydraulic pipes 6â18 mm in diameter. Ensure the vice is robustly fixed to a bench, tighten the vice jaws securely around the benderâs mounting points, and keep hands and tools clear of the rollers while operating. Using appropriate personal protective equipment and checking that the bender is firmly clamped before each use will ensure safe bending.

What pipe materials besides stainless steel can Pipe bender 6 Ã· 18 mm, type M 18 safely bend without damage?

Pipe bender 6 Ã· 18 mm, type M 18 is a very simple manual device intended for bending hydraulic pipes with external diameters from 6 to 18 mm. Besides stainless steel, it can safely bend without damage the following pipe materials, provided correct die selection, proper bending radius and careful, gradual operation: - Copper and copper alloys (e.g., brass, bronze). ductile, bend easily for hydraulic and refrigeration lines; risk of kinking is low if using appropriate rollers and supporting the tube. - Soft steel / mild steel (low-carbon). commonly used in hydraulic and pneumatic systems; tolerates manual bending well when using correct mandrels/rollers to prevent flattening. - Aluminum (soft grades). workable but more prone to springback and cracking at tight radii; use larger bending radii and gentle, progressive bends. - Cupronickel and similar non-ferrous alloys. generally ductile and bendable similar to copper/brass, with attention to support to avoid local deformation. - Annealed tubing of various metals. annealed (softened) condition improves bendability for many alloys compared with hard-tempered tubes. Materials that require caution or are not recommended for this manual pipe bender: - Hardened, high-alloy steels or high-strength alloys (e.g., certain tool steels, some stainless grades in work-hardened condition). risk of cracking or springback. - Thin-walled or very soft tubing without proper support. risk of kinking or collapsing. - Composite, plastic-lined or coated tubes. coatings may crack or delaminate; internal liners may be damaged. Practical tips to avoid damage: - Use appropriate bending dies/rollers sized to tube OD and desired bend radius. - Support the tube internally (mandrel) or use a backing spring for very thin-walled tubes. - Make bends gradually; avoid sharp radii beyond the tubeâs bendability. - Clamp securely in a vice-mounted setup as intended by Pipe bender 6 Ã· 18 mm, type M 18 to prevent slipping. If in doubt, test a sample piece or consult the tube manufacturerâs bend radius recommendations.
