Introduction to Steel lined PE Three way Pipe
First, add several layersPEWrap the film around the mold, and then spiral wrap the steel wire (Ø 0.5-1mm) around itPEOn the film, then wrap several layers around the steel wirePEThin, finally placed in the furnace and coiled into shape. Made using this techniquePE lined teeInner wall light
Due to the volume and external elastic force of the steel wire, a spiral shaped ripple is formed on the outer wall. Insert it into the steel pipe andPELining tube, and inPEFill the gap between the outer wall of the lining pipe and the inner wall of the steel pipe with filling resin (to remove residual air). This filling resin can tightly bond with steel pipes. At the same time, it can be tightly wrapped in a spiral shapePEOn the outer wall of the lining tube. After the resin is filled and cured, a spiral ripple is formed that meshes with the outer wall ripple of the lining. This structure is similar to the combination of nuts and bolts. On the one hand, it can enablePEThe thermal expansion and contraction of the lining are effectively limited and compensated; On the other hand, the stiffness of the steel wire is significantly improved by utilizing itPEThe ability of the lining to withstand negative pressure.
