Stainless steel pipe inspection method

The inspection of large-diameter stainless steel pipes first requires the inspection of the materials. The materials are strictly inspected before and after cleaning and before production. It is confirmed that the materials can meet the production requirements before they can be produced.

When using large-diameter stainless steel pipes, you must carefully observe a product to check whether there is any unqualified phenomena such as cracking and deformation. When inspecting the quality of large-diameter stainless steel industrial welded pipes, the first piece, middle piece, and tail piece can be used for quality inspection, but all corpses need to be inspected with tools, so that the large-diameter stainless steel pipe can be well guaranteed. quality.

When packaging large-diameter stainless steel pipes, inspections should be carried out to avoid the outflow of undesirable products due to improper packaging caused by improper packaging. Use tools to accurately inspect a large-diameter stainless steel pipe produced. When the large-diameter stainless steel pipe is out of the warehouse, it must be checked and reconfirmed.

Stainless steel pipe geometry and shape inspection:

1. Inspection of the bevel angle and blunt edge of the end face of the stainless steel pipe: square, chuck.

2. Stainless steel pipe wall thickness inspection: micrometer, ultrasonic thickness gauge, no less than 8 points at both ends and record.

3. Check the length of stainless steel pipe: steel tape measure, manual and automatic length measurement.

4. Inspection of the outer diameter and ovality of stainless steel pipe: caliper, vernier caliper ring gauge, measure the big point and small point.

5. Inspection of bending degree of stainless steel pipe: straightedge level (1m) and thin line of feeler gauge to measure bending degree per meter and full length bending.
