Outer extension edge is slided to by the chimb peace swelled outward in the upper and lower sides setting of chimb, the upper and lower sides of chimb is made to form pressure
Difference carries out stable occlusion convenient for chimb to tank body, by the way that end cap and extension edge is arranged when the outside of tank body is under pressure into slow
Punching, avoid easily expands outwardly crimping when traditional double seam is under pressure falls off, by pulling draw ring to make cover board from cover
Upper disengaging, cover stay on tank body, save material, while avoiding cover and throwing out pollution environment, economical environment-protective without care.This practicality is new
Type carries out stable occlusion by the way that triple seam is arranged, by pressure official post cover different above and below the second crimping to tank body, passes through
End cap and extension edge are set to pressure into row buffering, are not easy the damage that is crushed out of shape, ensures cover intensity and bending resistance, avoids
Cover falls off, simple in structure, convenient and practical.
