    Amalog-sonoscopeⅡ漏磁探傷設(shè)備“雙閘門”捕色軟件的開發(fā)

    Development of Double-gate Color-catching Software for Amalog-sonoscopeⅡFlux Leakage Inspection System

    • 摘要: Amalog-sonoscopeⅡ漏磁探傷設(shè)備在檢測過程中，因部分管坯存在一定深度的埋藏缺欠，檢測波形未能達(dá)到50%的報警閘門，存在缺陷管漏檢的質(zhì)量風(fēng)險。簡述漏磁檢測原理及其檢測的局限性，提出減少鋼管近表面埋藏缺陷漏檢的解決方法，并基于Visual Basic程序設(shè)計語言開發(fā)出“雙閘門”捕色軟件。該“雙閘門”捕色軟件設(shè)置有25%或30%高度的預(yù)警閘門，漏磁檢測時預(yù)警閘門與原報警閘門實(shí)現(xiàn)雙閘門。該軟件開發(fā)成本低，代碼量小，響應(yīng)速度快，可有效發(fā)現(xiàn)鋼管內(nèi)部一定深度的埋藏缺陷，應(yīng)用效果良好。

       

      Abstract: During the operation of the Amalog-sonoscopeⅡflux leakage inspection system, some pipes detected have defects as hidden with a certain depth, and the detection wave fails to reach 50%alarm gate.This means there exist a quality risk, i.e., some defected pipes might be undetected.Briefed in the article are the operation principle and detection limitation of the flux-leakage detection process.Accordingly the solution for reducing the missing rate of sub-surface hidden defect of the steel pipe is proposed.And based on the Visual Basic program design language, the Double Gate color-catching software is developed.This software is designed with 25%or 30%level early-alarm gate so as to realize the function of double gates, i.e., the early-alarm gate and the original alarm gate during the flux-leakage detection operation.The software has such advantages as low development costs, small amount of codes, and quick response, being capable of effectively detecting deeply-hidden steel pipe defects.The actual operation of the software shows its satisfactory efficiency.
