Beschreibung
Zusammenfassung:	The utility model relates to a pipeline technology field discloses a low temperature resistant explosion -proof feed pipe, and the pipe wall from interior to exterior of this feed pipe includes PP -R layer and PP -B layer in proper order, PP -R layer and PP -B layer be extrusion moulding altogether, and the thickness on PP -R layer and PP -B layer is than being 1: 1 -4: 1. The low temperature resistant explosion -proof feed pipe that this patent provided has solved current PP -R feed pipe temperature and has taken place the booster phenomenon when lower easily to plague for family or enterprise, and increased the use cost's of feed pipe technical problem.
