When high frequency welded pipe equipment usually produces standard vertebral welded pipes, it is inseparable from the last process of cutting the welded pipe online with a flying saw. And do you know what characteristics are required for the equipment for cutting welded pipes online? The following will introduce the requirements for online cutting of welded pipes for high frequency welded pipe equipment.

 

High frequency welded pipe equipment

 

Welded pipe online cutting equipment, they all have three common characteristics:

(1) Synchronized with the welded pipe being cut. That is to say, within the allowable range of high frequency welded pipe equipment, the cutting must be basically synchronized with the welded pipe at all times.

(2) Cut to any length. The dynamic shortest continuous cutting length is restricted by the speed of the unit, and the static cutting length is not limited.

(3) Time control. The action must be completed within the specified time, that is, from the start to the completion of the cut, to the return, and then to the preparation for the next cut, it must be completed within the time determined by the given pipe length. The time used for one sawing cycle must satisfy the formula: t=L/V+t'

t = time for one sawing cycle (seconds)

L=Welded pipe length (m)

V=Welded pipe running speed (m/s)

t'=waiting time after reset (t>0.5 seconds)

 

High frequency welded pipe equipment

 

Otherwise, the cutting equipment will not be able to cut the moving welded pipe within the next specified length. Its essence is that the cutting equipment must meet the requirements of the production line speed of high frequency welded pipe equipment. In a sense, the improvement of cutting equipment for decades has been carried out around these three characteristics. The process goal is higher cutting efficiency, higher precision and better section quality.

The essence of adjusting the diagonals of the used square pipe mill is to adjust the square of the square tube. In theory, if the two diagonals of the square tube are equal, the square tube is square. But not necessarily for the rectangular tube in physical form.
