A large number of second-hand real source, rapid integration of the entire used welded pipe production line. Installation and commissioning services can be provided at home and abroad to ensure the rapid production of qualified steel pipes.
Improvement countermeasures to solve the defect of the nozzle after the flying saw of the used welded pipe production line is disconnected
The nozzle defects of the used welded pipe production line are caused by flat heads, oblique heads, rubbing heads, and nozzle blockages. The following measures are put forward to solve the problems of nozzle defects.
The method of adjusting the r angle of the directly forming to square pipe mill when making pipes
When the square tube is manufactured by the directly forming to square pipe mill, the r-angle symmetry and the same size of the square tube are important conditions to measure the external beauty of the square tube, and it also affects the subsequent assembly requirements of the finished tube tooling.
How to place the impedance and calculate the length and outer diameter of the high frequency welded pipe equipment
The magnet bar is an open-circuit element in the welded pipe blank of the high frequency welded pipe equipment. When it is magnetized by the magnetic field of the induction coil, the magnetic field at both ends of the magnet bar will inevitably diverge, resulting in a decrease in the effective magnetic permeability. , and thus weaken the ability of the magnetic rod to increase the impedance of the inner loop.
Analysis of the rolling line of used welded pipe machine
The rolling line of the used welded pipe machine is all rolls on the welded pipe unit, including leveling rolls, forming flat rolls, guide rolls, squeeze rolls, deburring idlers, calendering rolls, sizing rolls, straightening rolls and other rolls.
How to adjust used square tube machines to improve square and rectangular pipes not square
How to adjust the square tube irregularity of the used square tube machines It is necessary to adjust whether the square tube square is qualified by combining the size adjustment and the tube surface adjustment.
How to adjust the convex surface of directly forming to square pipe mill when manufacturing square and rectangular pipes ?
When the directly forming to square pipe mill is used to manufacture the square pipe, the convex surface of the square pipe will cause the tolerance size, square tube shape, etc. to lose the angle measurement benchmark and size adjustment benchmark, and it is impossible to judge the true condition of the welded pipe.
Used square pipe machines to adjust the diagonal of square and rectangular tube
The essence of adjusting the diagonals of the used square pipe machine 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.
Tension adjustment of sizing section of high frequency welded pipe equipment
The process characteristics of the high frequency welded pipe equipment are: at the same time, the forming section, the welding section and the sizing section respectively perform continuous operations with completely different process connotations and process objectives for the same flexible welded pipe blank.
How to determine the main size of the guide ring of the high frequency welded pipe machine
The thickness of the guide ring is the main factor that determines the size of the opening angle of the high frequency welded pipe machine. The thickness of the guide ring of the commonly used unit is shown in the table below.
