Thermal meter detection

*The diameter of the Nippon Steel square tube production line in Japan is 500mm * 500mm * 20mm. The current diameter of square and rectangular pipes in European and American countries is 400 * 400 * 8mm-14mm. Using steel pipes to manufacture circular parts can improve material utilization, simplify manufacturing processes, save materials and processing time, such as rolling bearing rings, jack sleeves, etc. Currently, steel pipes are widely used to manufacture seamless low-alloy square tubes. Performance characteristics of low-alloy square tube: Low alloy square tube plasticity: Plasticity refers to the ability of metal materials to undergo plastic deformation (deformation) under load without failure. The hardness of low-alloy square tubes is a pointer to measure the softness and hardness of metal materials.

LUGB-MIKVortex flowmeter is a type of flowmeter that applies the Karman vortex principle, used to measure the flow rates of liquids, gases, and vapors, as well as turbid liquids containing small particles and impurities. It is widely used in petroleum, chemical, pharmaceutical, papermaking, metallurgy, power, and other industriesEnvironmental protection, food and other industries.

Regardless of the welding technology used in the manufacturing of stainless steel equipment for thermal meter testing, it is necessary to clean it after welding. All welding slag, splashes, stains, and oxidation colors must be removed, and the cleaning methods include mechanical cleaning and chemical cleaning. Mechanical cleaning includes grinding, polishing, sandblasting, and shot blasting. Carbon steel brushes should be avoided to prevent surface rust. To achieve corrosion resistance, it can be soaked in a mixture of HNO3 and HF, or acid washed passivation paste can be used. In fact, the combination of mechanical cleaning and chemical cleaning is commonly used. The cleaning of forged castings often results in a layer of oxide scale, lubricant, or oxide contamination on the surface of stainless steel workpieces after hot processing such as forging and casting. Pollutants include graphite, molybdenum disulfide, and carbon dioxide.

·High strength piezoelectric crystal, integrally formed, impact resistant

·Compatible with liquid, gas, thermal oil, and steam metering

·Sonic nozzle calibration, high repeatability, high measurement accuracy

·Temperature compensation and pressure temperature can be freely selected to meet more on-site needs

·The circuit board is aged and operated before leaving the factory, and the entire meter is calibrated one by one, which is more suitable for on-site use

·The sensing head has anti vibration and anti-interference packaging technology, with stronger on-site anti-interference ability
