1. I-Metallography
I-Metallography ingenye yezindlela eziyinhloko zokuhlukanisa amapayipi ensimbi ashiselweamapayipi ensimbi angenamthungo. Amapayipi ensimbi ane-high-frequency ukumelana awafaki izinto zokushisela, ngakho-ke i-weld seam epayipi lensimbi ehlanganisiwe incane kakhulu. Uma kusetshenziswe indlela yokugaya bese kugqwala, i-weld seam ayikwazi ukubonakala ngokucacile. Uma ipayipi lensimbi elishiselwe ukumelana ne-high-frequency lishiselwe futhi lingakenzi ukwelashwa kokushisa, isakhiwo sokushisela sizohluka kakhulu ezintweni eziwumzali zepayipi lensimbi. Ngalesi sikhathi, indlela ye-metallographic ingasetshenziswa ukuhlukanisa amapayipi ensimbi ashiselwe kumapayipi ensimbi angenamthungo. Enqubweni yokuhlukanisa amapayipi amabili ensimbi, kuyadingeka ukusika isampula encane ngobude nobubanzi obungama-40mm endaweni yokushisela, ukwenza ukugaya okunzima, ukugaya okuhle nokupholisha, bese ubheka isakhiwo ngaphansi kwe-microscope ye-metallographic. Lapho i-ferrite ne-widmanstatten, impahla yomzali kanye nesakhiwo sendawo yokushisela kubonakala, ipayipi lensimbi elishiselwe kanye nepayipi lensimbi engenamthungo kungahlukaniswa ngokunembile.
2. Indlela yokugqwala
Enqubweni yokusebenzisa indlela yokugqwala ukuhlukanisa amapayipi ensimbi ashiselwe namapayipi ensimbi angenamthungo, ukushisela kwepayipi lensimbi elicutshunguliwe kufanele kupholishwe. Ngemuva kokuthi ukupholisha sekuqediwe, izimpawu zokupholisha kufanele zibonakale. Khona-ke, ubuso bokugcina bupholishwa nge-sandpaper ekushiseni, futhi ubuso bokugcina buphathwa nge-5% ye-nitric acid alcohol solution. Uma kuvela i-weld esobala, kungafakazelwa ukuthi ipayipi lensimbi liyipayipi lensimbi elishiselwe. Awukho umehluko osobala ebusweni bokugcina bepayipi lensimbi elingenamthungo ngemva kokugqwala.
3. Hlukanisa amapayipi ensimbi ashiselwe kanye namapayipi ensimbi angenamthungo ngokuya ngenqubo
Enqubweni yokuhlukanisaamapayipi ensimbi ashiselwenamapayipi ensimbi angenamthungo ngokwenqubo, wonke amapayipi ensimbi ashiselwe ashiselwe ngokuvumelana nezinqubo ezifana nokugoqa okubandayo nokukhipha. Ngaphezu kwalokho, lapho imvamisa ephezulu, amapayipi wokushisela we-arc aphansi kanye namapayipi welding welding asetshenziselwa ukushisela amapayipi ensimbi, ukushiselwa kwamapayipi avunguzayo kanye nokushisela ipayipi lomthungo oqondile kuzokwakhiwa, okuzokwenza amapayipi ensimbi ayindilinga, amapayipi ensimbi ayizikwele, insimbi eyi-oval. amapayipi, amapayipi ensimbi angunxantathu, amapayipi ensimbi anezinhlangothi ezine, amapayipi ensimbi ashwabene, amapayipi ensimbi ane-octagonal, kanye namapayipi ensimbi ayinkimbinkimbi nakakhulu. Ngamafuphi, izinqubo ezihlukene zizokwakha amapayipi ensimbi anobunjwa obuhlukene, ukuze amapayipi ensimbi ashiselwe namapayipi ensimbi angenamthungo akwazi ukuhlukaniswa ngokucacile. Nokho, emkhankasweni wokuhlukanisa amapayipi ensimbi angenamthungo ngokwenqubo, ahlukaniswa ngokuyinhloko ngokwezindlela zokwelashwa eziginqikayo nezibandayo, futhi amapayipi ensimbi angenamthungo nawo anezinhlobo ezimbili eziyinhloko, okungamapayipi ensimbi angenamthungo agingqiwe ashisayo kanye namakhaza- amapayipi ensimbi angena nekhono. Amapayipi ensimbi angenamthungo agingqiwe ashisayo akhiwa ngokubhoboza, ukugingqika nezinye izinqubo, ikakhulukazi amapayipi ensimbi anobubanzi obukhulu nawugqinsi ahlanganiswe yile nqubo; amapayipi adonswa abandayo akhiwa ngokudweba okubandayo kwamapayipi, futhi amandla ezinto ezibonakalayo aphansi, kodwa izindawo zayo zangaphandle nezingaphakathi zibushelelezi.
