Range is 0.8-2mm, and caliber range should be annealed in 12.7-108mm, the helical bellows and meet manual bending and wanted
It asks.
As an improvement, the pipe end ripple straight tube is the straight tube of 4 meters or 6 meters scales and its wall thickness range is 0.8-2mm, pipe
Diameter range sets the corresponding pitch of waves, the depth of convolution in 12.7-108mm, the bellows segment at the different caliber both ends of the pipe end ripple straight tube
It is consistent with the helical bellows ripple of same size.
As an improvement, the helical bellows are connect with outermost pipe end ripple straight tube.
As an improvement, the hand of spiral phase of the helical bellows and the pipe end ripple straight tube hand of spiral and screw thread nut
Instead, to realize the better stop of stop washer and locking.
The invention has the benefit that
The present invention use spiral jointing sealing method, sealing ring end face with spirally connect end surface be in oblique angle 45~
75 ° of inclined-plane cooperations, sealing performance high reliablity, bearing capacity are strong.Using stop washer internal screw thread and helical bellows or pipe end
The mode of the ripple end cooperation of ripple straight tube, realizes screw-type fastening, fastens relatively reliable.Connected using spiral jointing
The method connect connects pipe end ripple straight tube, helical bellows by spiral jointing, and site operation can be used in combination, short
Distance can length cutting bellows piping as needed.To which compared with conventional art, scene is set without bulky hydraulic card pressure
Standby or welding equipment, execute-in-place convenience greatly improve.Spiral type corrugated pipe can meet manual bending, thus curved in small distance
Song can reduce elbow use.
