輸(shu)(shu)(shu)送(song)石油(you)、天然(ran)氣的聚(ju)乙(yi)(yi)烯(xi)管(guan)(guan)道(dao)是(shi)輸(shu)(shu)(shu)送(song)能(neng)(neng)源(yuan)介質的關鍵運輸(shu)(shu)(shu)設施(shi),被認為是(shi)國家能(neng)(neng)源(yuan)運輸(shu)(shu)(shu)的"血管(guan)(guan)"。與傳統金屬管(guan)(guan)道(dao)相比(bi),聚(ju)乙(yi)(yi)烯(xi)管(guan)(guan)道(dao)具有(you)柔韌性好、耐腐蝕、使用壽命(ming)長和(he)不(bu)污染輸(shu)(shu)(shu)送(song)介質等顯著(zhu)優點(dian),是(shi)公認的"綠色(se)"管(guan)(guan)道(dao)。但是(shi)管(guan)(guan)道(dao)焊接(jie)接(jie)頭端面存在(zai)的缺陷(xian)可(ke)能(neng)(neng)會嚴(yan)重(zhong)影響接(jie)頭的質量,有(you)些傳統無(wu)損檢(jian)測(ce)方法因為對檢(jian)測(ce)對象有(you)嚴(yan)格要求并不(bu)適用聚(ju)乙(yi)(yi)烯(xi)材(cai)料的檢(jian)測(ce),基(ji)于超聲(sheng)波檢(jian)測(ce)的超聲(sheng)相控陣(zhen)檢(jian)測(ce)技術能(neng)(neng)夠對缺陷(xian)信號進行(xing)完整采集,并能(neng)(neng)實現二維成像,極大地(di)提高了對聚(ju)乙(yi)(yi)烯(xi)管(guan)(guan)道(dao)缺陷(xian)檢(jian)測(ce)的效果。
