  In pipe ultrasonic flaw detection, relative motion of probe and the specimen on the test surface is called scanning. Scan generally consider two principles, one is to guarantee the whole steel pipe inspection has enough acoustic coverage to avoid detection; two is the search process of beam incident direction always conform to the required standards.

  ASTM A578-92 welded pipe

  1 continuous along the perpendicular center line grid scan line, the lattice spacing is 9

  Inch (225mm) or in accordance with the manufacturer's choice.

  2 continuous rolling along the direction perpendicular to the plate parallel to the center of the line scan, scan

  Spacing of 4 inches or 3 inches (100mm) (75mm).

  The center line of 3 continuous rolling along the main direction of the plate parallel line scan, scan

  Spacing of 3 inches (75mm) or less.

  We have adopted advanced production equipment and technologies to manufacture our pipe tee and pipe elbow,which can not only improve product quality, but also save raw materials. Our products have high strength, good toughness and resistance to corrosion.
