How to ensure the quality of high frequency welded steel pipe?
How to ensure that the product quality of the high frequency welded steel pipe meets the requirements of the technical standards in production process? Raw materials, welding technology, roll adjustment, roll material, equipment failure, production environment and other reasons should be taken into consideration. Next, Great Steel Pipe will introduce that for all of you.
Raw material
Factors affecting the quality of raw materials mainly include three aspects, the unstable mechanical properties of the steel strip, the surface defects of the strip and the large deviation of geometric size. Therefore, tube manufacturers should control from these three aspects.
High frequency welding
In the process of high frequency welding of steel pipe, welding technology and the control of process parameters, the position of the sensor and resistor,etc., have a great influence on the weld pipe weld quality.
Roller adjustment
The employee ought to master the roll adjustment technique once ever-changing the roll. In the production method, once the roll is broken or abrasive badly ad, we want to exchange a part of the roll on the unit, or we want to exchange the full roll once the quantity of a product is enough once continuous production. Tube makers ought to alter the roll to get an honest quality of the pipe.If the roll adjustment isn't smart, simple to cause the tube seam torsion, fastening of steel pipe, lap fastening, edge waves, drums and body surface indentation or scratches, massive ovality of steel pipe and alternative defects, therefore the roll ought to be grasped roll adjustment ability.
