The production line for both three layer PE pipe and epoxy powder inner anticorrosion pipe came from the reformation of an original production line of three layer PE pipe. The main problems to have been solved are as follows, convert the conventional spray gun deflector into two parts of diversion nozzle and gun wick to suit for different pipe diameters; adopt two stage retrieval equipment to increase powder retrieval rate and improve work environment; enlarge the calibres of gas jet and Venturi pump jet to increase powder output 20% above to ensure the spry coating thickness; design gun pushing device to raise automatic production level.
