Specification of heat meter

The production of ML35 steel follows the GB6478-86 standard and is mainly used to manufacture 8.8 grade high-strength standard parts. Shougang proposed that the average yield strength of ML35 cold heading steel is 380MPa, and the qualified yield strength is 380MPa; The average tensile strength of ML35 cold heading steel is 576MPa, and the qualified tensile strength is 576MPa; The average cross-sectional shrinkage rate of ML35 cold heading steel is 56%, and the qualified surface shrinkage rate is 56%. Shougang and Baosteel produce ML35 cold heading steel using an 80 ton converter smelting process. The slag making system of Baosteel adopts the single slag method, with oxygen supply system setting oxygen pressure and changing gun position. The endpoint control is carbon blowing and post furnace carbon addition.

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.

The DONKIN direct buried gate valve has been used for many years in Hong Kong China Gas, Zhongshan, Panyu and other places. We have also commissioned South China University of Technology to conduct comprehensive performance experiments on its chemical composition and mechanical strength, and the results are satisfactory. The gate valve of FRIATEC company in Germany adopts a steel structure welded shell, and the gate is made of integral precious metal. The shell is made of PUE asphalt thermal spraying. Good anti-corrosion performance and can be directly welded to pipelines, making it easy to prevent corrosion. Based on local conditions, determine the scientific principles for valve replacement, and replace all domestic oil seal valves, domestic disc valves, domestic gate valves, domestic flange ball valves, and globe valves; The steel valves used in the gas plastic pipeline network should also be replaced with plastic valves for future operation and management, but the implementation is temporarily suspended.

·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
