spiral pipe forming machines

The results show that the yield pressure of spiral welded pipe and straight welded pipe is consistent with the measured and theoretical value of blasting pressure, and the deviation is close.But the spiral welded pipe is lower than the straight welded pipe in both yield pressure and blasting pressure.The blasting test also shows that the toroidal deformation rate of spiral welded pipe blasting mouth is obviously higher than that of straight welded pipe.It is proved that the plastic deformation capacity of spiral welded pipe is better than that of straight welded pipe, and the blasting hole is generally limited to one pitch, which is caused by the constraint of spiral welding seam on the crack expansion.

The micrometer can measure the length accurately to 0.01mm and the measuring range is several centimeters.Part of it is processed into a thread with a pitch of 0.5mm. When it rotates in the screw sleeve of fixed casing B, forward or backward, movable casing C and screw rod are connected into a whole, and its periphery is divided into 50 grids.The whole turn number of screw rotation is measured by a 0.5mm scrip on the fixed sleeve, and the part less than one circle is measured by scrip on the periphery of the movable sleeve, and then the measurement result needs to be evaluated by one decimal
