This bellows of flat bellows and adoption add oil pipe

The utility model discloses a flat bellows. This flat bellows includes pipe wall and bellied ripple, the ripple for setting up the semi -ring ripple in the pipe wall both sides, semi -ring corrugated both ends tangent or crossingly constituted level and smooth wall with the pipe wall, level the axis that the wall is on a parallel with the bellows and arrange. It is the equal of that the strengthening rib makes the bellows axial obtain to support to level the wall, has improved the axial structural strength of bellows on the one hand, reduces the deflection that bellows internal -external differential pressure leads to, the trend of bellows is convenient for arrange by on the other hand, and the two is held concurrently. Adopt the oil pipe that adds of bellows, improved the intensity that adds oil pipe on the whole, reduced the deflection that internal -external differential pressure leads to. 本实用新型公开了种扁平波纹管。该扁平波纹管包括管壁和凸起的波纹，所述的波纹为设置在管壁两侧的半环波纹，半环波纹的两端与管壁相切或者相交构成了平整壁，平整壁平行于波纹管的轴线布置。平整壁相当于是加强筋使得波纹管轴向获得支撑，方面提高了波纹
