UHMWPE composite flaring lining pipe 

In view of various defects existing in manual welding of flanges used in steel-lined UHMW-PE pipes（UHMWPE Mining pipe、UHMWPE Dredge Pipe、UHMWPE Roller Pipe）, our company has gradually replaced manual welding with automatic flat welding flange welding machine, and the welding sequence adopts "carbon dioxide gas shielding" or mixed welding technology. The welding machine is fully capable of guaranteeing welding quality, ensuring no leakage of slurry and no environmental pollution in the process of pipeline use.  Specifications weight  Mpa Working pressure  Φ63×(5+10) 8.37 15 Φ75×(3+10) 6.93 8.5 Φ89×(3+10) 8.34 7 Φ102×(5+10) 14.36 7.3 Φ…
