are purchasing these types of machines so they can sew extra large thread sizes up to Tex 500 or Tex 600 thread sizes. Another option for sewing heavy threads on 301 lockstitch machines is to sew the heavy thread in the bobbin and using a regular size thread in the needle. This means that the seam is inverted when it is sewn.
Ultrasonic Flaw Detectors range from easy-to-use, Hand-held Ultrasonic Flaw Detectors to Phased Array Ultrasonic Flaw Detectors for many Ultrasonic Flaw Detection Applications including Crack Detection, Weld Inspection, Defect Sizing and more... SUPOR-Super Idea for Ultrasonic Inspection.
High voltage holiday detection. High voltage holiday test is normally used to determine the existences of discontinuities in coating films. The high voltage, or porosity technique, can be used to test coatings up to 25mm (1) thick and is ideal for inspecting pipelines and other protective coatings. Coatings on concrete can also be tested using this method. There are two types of high voltage holiday detectors - Continuous DC and Pulsed DC.
