Inspection Test

• 

  Bending Machine

  This machine test special plug lead and folding strength of wire.The sample test is fixed on the fixture, and add a certain load, test fixture swinging, examine the break rate after a certain number of times, or until all bolt can't electricity to check its total number of swing.The function of automatic counting, bending specimen is no electricity to break, and can automatically stop the operation.
• 

  Impact Test Machine

  Low temperature and impact test of low temperature tank, with impact testing machine is a kind of form a complete set of low temperature environment for the sample to a special test equipment, widely used in petroleum chemical industry, metallurgy, boiler, pressure vessel, steel, steel, metal, casting, pumps, valves, fasteners, vehicle, machinery manufacturing, aerospace and scientific research industry sectors such as physical and chemical test in low temperature.
• 

  Ultrasonic Flaw Detector

  Ultrasonic flaw detection has high detection sensitivity, to crack in the steel pipe straight defects such as sensitive, also can detect non-metallic inclusions such as volume type of defect.
• 

  Metallurgical Micriscope

  Test metal organization, such as rolling, forging and heat treatment processing leads to changes in micro- structure, grain size inspection or the distribution of non- metallic inclusion and other groups, such as size and material damage judgment, etc.
• 

  Hardness Test

  The main purpose of the hardness test is to determine the applicability of the steel pipe, or steel pipefor a specific purpose by hardening or softening effect, Methods is including brinell, rockwell and vickers hardness index to measure the hardness.
• 

  Chemical Analysis

  Main purpose of chemical analysis to determine whether the batch product accord with standard of the grade of steel products, and to the analysis of the results should be taken as the basis of the judgement of the batch product.Chemical composition analysis instrument is mainly used direct reading spectrometer, carbon sulfur analyzer to finish a lot of online product production testing tasks.
