HG STEEL PIPE have quality inspection center to provide testing services to the production process and finished products.The laboratory has 14sets of test equipment, including Flatting test units, Hydraulic test unit and the Ultrasonic flaw detection units used in the production workshop at the scene. It could detect 31 kinds of projects, including the metal material and coating material physical and chemical properties. A total of 8 kinds of standard to be used and standard software. Inspection and Quarantine has become a technology center in Liaoning Anshan Branch of metallic materials under the testing room.
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.
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.
Checking the quality of pipe connection leak test, check the vacuum pipe system maintain the performance of the vacuum test and based on the fire safety considerations for the leakage test, etc.
Test metal organization, such as rolling, forging and heat treatment processing leads to changes in microstructure, grain size inspection or the distribution of non- metallic inclusion and other groups, such as size and material damage judgment, etc.
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.
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 asphysical and chemical test in low temperature.
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.
