Inflatable bend forms against wrinkles

PVC tube can be bent in various ways. Usually, the tube is heated and bent around a rigid former. A part is installed inside the tube to prevent wrinkles at the bend. Sometimes, this is a steel flat spring, or, in case of pipes with a large diameter, a flexible rubber cylinder. Often, the methods used are impractical or made of expensive materials.

Buitink developed a light weight inflatable bend former. Its light weight means it is easy to use. In addition, it is made of relatively inexpensive materials. The former is made of a gas-tight core, which can be inflated to the desired pressure, and cloth made of an inelastic material. Using this former, tubes with a large diameter can be easily and quickly bent. The former can be custom made. Contact us for more information.
