New technology combining PVC pipe and copper pipe
When it comes to PVC pipe, we will be very familiar with it, but when it comes to the technology of combining PVC pipe with copper pipe, we may be very unfamiliar with it. In the current market, the joint of PVC pipe with copper pipe is also a big problem. In Japan, a piece of jiushui chemical company is studying the PVC pipe and copper pipe joint.
(1) In advance in the copper tube one end of the inner wall coated with a curable special adhesive, and then stretch PVC pipe into the copper tube, and then tilt and roll along the pipe axis, so that the remaining adhesive removed, finally make the liquid binder solidified.
(2) It is primarily to connect the medium diameter PVC pipe and steel pipe with the flange:
1, PVC pipe and steel pipe, cast iron pipe joint, usually choose flange joint: medium diameter and above the standard. Small diameter valve joint can be selected: socket joint and external thread joint, tooth end and metal pipe joint of the same diameter. Another method is to select the socket joint and the internal thread adapter: the connector end is the female screw.
2, PVC pipe and metal pipe joint, medium - large diameter pipe selection bevel ring, that is, PVC pipe cooperation on PVC bevel ring made of flat mouth, cooperation with metal flange. Can be connected with the metal pipe flange with screws, and PVC pipe end, can choose the metal pipe flange. Same can use looped joint, outside diameter requirement common.
This technology is difficult, but if it is used on a large scale, it will also bring new opportunities for PVC pipes and the construction industry.
