During the bending process (Mr. Hu from Zhijiu on phone/WeChat 139-6219-3405), the stamping method is used: the pipe end is expanded to the required size and shape using a tapered core on a punch press; Afterwards, the bending forming method will also be adopted. There are three commonly used methods, one is called stretching method, another is called stamping method, and the third is the roller method, which has 3-4 rollers, two fixed rollers, one adjusting roller, and adjusting the fixed roller spacing. The finished pipe fittings are bent.

During the bending process, the bulging method is also used: one method involves placing rubber inside the pipe and compressing it with a punch to make the pipe protrude into shape; Another method is hydraulic bulging forming, which fills the middle of the pipe with liquid, and the liquid pressure bulges the Suzhou bend into the desired shape. This method is mostly used in the production of corrugated pipe bend manufacturers.

In daily life and work. It is inevitable to encounter straight pipes being bent into various shapes for use. Suzhou bend pipe is bent using a complete set of bending molds. Regardless of the type of machinery and equipment, most of them use Suzhou bend pipe, mainly for oil, gas, infusion, etc. It occupies an important position in airplanes and their engines. So, what is the price for processing by bend pipe manufacturers? Please contact us!
