Quality inspection of stainless steel pipe

1. Tube Surface checking. Checking the surface of the stainless steel tube blank under the integrated light, and the estimated distance is 45±5 cm.


2. Pipe surface checking. Inspection according to the quality inspection standard of the polished surface of the stainless steel pipe.


3. The organic chemical composition testing of stainless steel plates is authorized to entrust an external testing center for testing.


4. The non-concentricity of the stainless steel pipe is accurately measured at three places of the stainless steel pipe diameter with the symmetry of a micrometer, which is indicated by the difference between the high value and the minimum value.


5. Diameter specifications, inner diameter specifications, and dimensions are accurately measured with a micrometer. The arc position is accurately measured with an R gauge, and the length specification is accurately measured with a meter ruler. The thickness of the stainless steel pipe is accurately measured with a special vernier caliper.


6. The stainless steel pipe is cold drawn at room temperature to check the cohesion of the stainless steel pipe. The bending angle of view is 90, the bending radius is based on the bending radius of the product, and the welding is located on the inner side of the bending direction. After the bending is completed, check the welding seam if it is cracked.
