As the tube is gradually cooled to harden, width can be increased to 3 ~ 4mm, slot spacing can be increased. Vacuum tank cooling effect is better than the vacuum holes, because the water forms a film through these slots to help slide the pipe sizing and cooling jacket enables cooling area increases. Therefore, the structure is good or bad vacuum forming region directly affect the cooling effect of the sizing sleeve, during the length of the PERT pipe sizing sleeve, the outer surface of the pipe must be hardened, leaving the tube when sizing sleeve, wall hardening depth It must be sufficient to support the weight of the tube, not deformed or broken, otherwise it will affect the dimensional accuracy of the tube. While also improve sizing sleeve length to increase the cooling effect, but there is the difficulty of processing, high production cost, convenient operation, caused by excessive friction, increasing traction power PPR pipe sizing sleeve, while the tube will produce stress, reduced the tube surface finish. Therefore, the sizing sleeve length should be appropriate, generally about 10 to 12 times the inner diameter. Sizing sleeve suitably good thermal conductivity metal, pipe sizing sleeve at home and abroad are working with a wear-resistant copper alloys.
