PVC single wall bellows pipe

PVC single wall corrugated pipe description

PVC single wall corrugated pipe is PVC as the main raw material, the extrusion blow molding, it is the new product development in 1970s. PVC single wall corrugated pipe with the structure of its ring groove, can be both rigid and flexible PVC pipe, so that the pipe has the characteristics of flexible, can be used to transport some of the liquid and gas as well as the pre buried wire.

The inner and outer surfaces of the single wall corrugated pipe are corrugated, and their bending and flexibility are excellent, but the fluid resistance is large, and it is easy to produce the suspended sediment at the inner surface of the inner surface. So PVC single wall corrugated pipe for the wall is thin, the intensity of the requirements is not very high and the need for free bending of small diameter tubes, such as threading pipe, exhaust pipe, exhaust pipe, etc..

The single wall corrugated pipe is based on the basic structure parameters, such as wall thickness, wave height, wave thickness, etc.. Corrugated height can be expressed by K, which is the ratio of the outer diameter and inner diameter of the corrugated pipe, the greater the value, the higher the height of the ripples. Waveform of the bellows, according to along the axial and sectioned after geometry can be divided into spiral shape, U shape, C-shaped, S-shaped, V and Omega shaped, waveform of pipe stiffness and strength have certain effect.

PVC single wall corrugated pipe and PVC pipe production technology is the main difference between the extrusion ring shaped section of the tube, while the heat in the corrugated pipe forming in the corrugated tube, as described in the process flow, production process and forming principle.
