The following is a detailed description of the FV-810 automatic hardness tester, the ARL iSPARK 8860 straightness spectrometer and the BX53MRF-S Olympus microscope:
FV-810 Automatic hardness tester:

This FV-810 automatic hardness tester shows the world-class steel pipe quality inspection technology level and excellent performance. The latest model introduced by Hwa Yang ensures cutting-edge technology and smooth operation. The FV-810 automatic hardness tester fully meets the test requirements of API 5L PSL2 on the hardness of HV10 steel pipe, which fully confirms its professional level and high accuracy. The equipment is equipped with a highly integrated color LCD touch screen display and multi-layer board design, which not only improves the operation efficiency, but also makes the use process more intuitive and convenient. In addition, the hardness tester integrates advanced features such as USB port output, cylindrical/spherical correction, and sample thickness calculation, which make the test process more efficient and accurate. What's more, the FV-810 fully automatic hardness tester has a clear field of view, making indentation measurement a breeze. Its replaceable filter design enables accurate sample measurement even under adverse conditions by changing the filter. The replaceable apertures and field of view apertures ensure a wide field of view from low magnification to high magnification, giving the operator more flexibility and choice. At the same time, the device also has X/Y coordinate display function, and the stage coordinates are displayed on the display together with the digital miniature head, which provides strong support for accurate measurement. In addition, the FV-810 fully automatic hardness tester supports the installation of up to four objectives at the same time, which makes measurement and observation from low magnification to high magnification more common and convenient. This model also supports the simultaneous installation of two HV/HK indenters, a feature that enables simultaneous microhardness testing of two different HV/HK, greatly improving the efficiency of steel pipe inspection.

ARL iSPARK 8860 Straightness Spectrometer:

This latest model of spectrometer has higher accuracy and wider analytical capabilities, and can better meet the API standard requirements for accurate analysis, providing reliable technical support for steel pipe inspection analysis. The spectrometer is characterized by its high accuracy, high precision and high detection limit, ensuring the reliability and stability of the analysis results. In addition, its ultra-fast online analysis of non-metallic impurities makes the analysis process more efficient and fast. The ARL iSPARK 8860 straightness spectrometer is not only suitable for routine analysis, but also maximizes the complex requirements of the analyst. Its durable and reliable structural design and manufacturing process ensure that the instrument can maintain excellent analytical performance in a variety of harsh environments. The spectrometer uses arc/spark excited direct reading spectroscopy to perform rapid elemental analysis of steel tube samples. This technology can meet the vast majority of analysis requirements of steel pipe production and processing from incoming detection to finished product detection, and provides strong technical support for HUAYANG STEEL PIPE. The technical advantages of the spectrometer are reflected in several aspects. First of all, it uses a concave machine engraving grating with a focusing length of 1 meter, which has the characteristics of high light intensity, higher order spectral lines and good imaging quality. Secondly, the spectrum chamber adopts a vacuum, constant temperature and shock-proof design to ensure that the spectrometer is not affected by external conditions when in use. In addition, the excitation table is equipped with a water cooling device to ensure the reliability and stability of the analysis results, especially for the analysis of large tasks. In addition, the ARL iSPARK 8860 straightness spectrometer also uses an incident lens protected by argon to prevent the lens from contaminating and carrying away organic vapors in the optical chamber. At the same time, it uses a large diameter photomultiplier with good working performance, small dark current and high signal-to-noise ratio, which improves the accuracy and stability of the analysis. The fatigue lamp set in the spectrum room can avoid the photomultiplier tube blindness due to sudden acceptance of strong light signal, extend the life of the photomultiplier tube, and improve the analysis speed and stability.

BX53MRF-S Olympus Microscope:
The BX53MRF-S Olympus microscope is a microscope equipment imported from Japan and is known for its high definition and world-class brand status. The microscope uses advanced optical technology and design concepts to provide an exceptional viewing experience for the operator. Its features include a wide field of view observation head, positive and negative image options, a variety of stage configurations and excellent optical performance, making the observation process more convenient and comfortable. In addition, a variety of stage configurations are also a highlight of this microscope. The high wear resistance ceramic coating coaxial stage not only ensures the stability of the observation, but also greatly extends the service life of the stage. The design of the converter is even more ingenious, and the internal five/six/seven hole objective can be changed to provide more flexibility for the operator. Of course, a good microscope is inseparable from its optical system. The UIS2 optical system used by the BX53MRF-S ensures the high definition of the image and the authenticity of the color. Finally, the lighting system is also an important part of this microscope. The built-in Kohler illuminator ensures the uniformity and stability of the light source and provides good lighting conditions for observation.
The introduction and use of FV-810 automatic hardness tester, ARL iSPARK 8860 direct reading spectrometer and BX53MRF-S Olympus microscope will greatly enhance the competitiveness of Huayang Company in steel pipe quality inspection. The high performance and accuracy of these equipment ensure the reliability of the test and analysis results, and provide a solid technical guarantee for the quality of Huayang's products. When selecting these high-end precision instruments, we will give full consideration to their advanced technical parameters, ease of operation and the perfection of follow-up services. The FV-810 automatic hardness tester, the ARL iSPARK 8860 direct reading spectrometer and the BX53MRF-S Olinbath microscope are all produced by specialized manufacturers in their respective fields, which are not only technologically advanced, but also have good after-sales service. These devices have played an irreplaceable role in improving the quality inspection of Huayang's steel pipes. In summary, the introduction and use of these three new equipment will certainly bring revolutionary changes and improvements to the steel pipe testing work of HUAYANG STEEL PIPE.
