Analyze nozzle defects of used welded pipe production line

 

Deflated head defect

 

Used welded pipe production line

 

Shrinking heads mostly occur on thin-walled tubes. The fundamental reason is that the tube wall is thin and the ability to resist the impact of the saw blade is weak. The specific reasons are as follows:

(1) The saw blade has been used for too long, and the saw tooth wear is more serious;

(2) The thickness of the saw blade is not well chosen, and it is too thick;

(3) The pressure of the sawing cylinder is too large.

 

Oblique head defect

 

Used welded pipe production line

 

Main reasons for oblique head:

(1) The flying saw is not synchronized with the welded pipe.

(2) There is radial vibration in the bearing of the sawing spindle.

(3) The saw blade shakes greatly.

(4) The operation of the sawing trolley is unstable.

 

Wiping defects

 

Used welded pipe production line

 

Main reasons for head rubbing:

(1) Improper design of main parameters of lifting saw;

(2) The design plan for the main parameters of the loose clamp is too early

(3) There is axial shaking of the sawing spindle bearing

 

Nozzle blocking defect

 

Used welded pipe production line

 

Main reasons for nozzle blockage:

(1) Different steps;

(2) The saw blade shakes a lot;

(3) There is radial sway on the back of the saw;

 

The above is used welded pipe production line, the cause of the nozzle defect after the flying saw is disconnected. I hope it will be of some help to you.

Analyzing the roll life of a used ERW tube mill
Analyzing the roll life of a used ERW tube mill
In the production of used ERW tube mills, the roll is the key and important special tool. Roll consumption is also a key tool for manipulating product costs. In addition, the normal operation of the roll will directly affect the output and quality of welded pipe manufacturing. Therefore, welded pipe manufacturers attach great importance to and strive to improve the service life of the roll.

Adjusting the welding seam position of square and rectangular pipes made by directly forming to square pipe mill (2)
Adjusting the welding seam position of square and rectangular pipes made by directly forming to square pipe mill (2)
Judging that the quality of the square tube produced by the directly forming to square pipe mill meets the standard is based on a large number of inspection data of the microhardness of the weld and the microhardness of the base material. The former is much higher than the latter. It is for this reason that the weld is usually not placed at a positive angle, but placed within t~(t+5mm) from the corner edge to reduce the risk of weld cracks. This requires effective control of the weld position. Control methods include forming roll method, guide roll method and sizing roll method.
