Putkivääntimiä

Putkivääntimiä is a Finnish term that translates to "pipe bender" in English. A pipe bender is a tool used to bend pipes, typically made of metal, into a desired shape. This is commonly done in plumbing, HVAC, and metal fabrication industries.

There are various types of pipe benders, ranging from simple manual tools to complex hydraulic or electric machines. Manual pipe benders often utilize leverage to bend softer metal pipes like copper or thin-walled steel. These can be hand-held or bench-mounted. For larger diameter pipes or harder metals, hydraulic or electric pipe benders are employed. These tools provide significantly more force, allowing for precise and controlled bending.

The bending process usually involves placing the pipe into a die or groove on the bender and then applying force to bend it around a former. The accuracy of the bend is critical in many applications to ensure proper fit and functionality, especially in systems requiring sealed connections. Different bending techniques exist, such as rotary draw bending, ram bending, and roll bending, each suited for specific pipe materials, sizes, and bend radii. The selection of the appropriate pipe bender and technique depends on the material, wall thickness, desired bend angle, and the radius of the bend.
