1. I-Metallographys
I-Metallographys ingenye yezindlela eziphambili zokuhlukanisa amapayipi ensimbi afakwe kuwoAmapayipi ensimbi angenamthungo. Amapayipi e-high affleency we-welded akwengezi izinto zokwehlukanisa, ngakho-ke umthungo we-weld epayipi lensimbi enomdlandla. Uma indlela yokugaya kabi bese kusetshenziswa ukugqwala, umthungo we-weld akakwazi ukubonwa kahle. Lapho ipayipi lensimbi eliphakeme le-weldency welded lived futhi alikaze liphule ukwelashwa okushisa, isakhiwo se-weld sizohluka ngokusobala ezintweni zomzali ngepayipi lensimbi. Ngalesi sikhathi, indlela ye-metallographic ingasetshenziswa ukuhlukanisa amapayipi ensimbi afakwe emanzini avela kumapayipi ensimbi engenamthungo. Enqubweni yokuhlukanisa amapayipi amabili ensimbi, kuyadingeka ukusika isampula elincane ngobude nobubanzi be-40mm endaweni ye-welding, yenza ukugaya okunamandla, ukugaya okuhle nokuphoqelela, bese ubheka isakhiwo ngaphansi kwesibonakhulu se-metallographic. Lapho uFerrite futhi eWdmanstatten, ukwakheka komzali nesakhiwo se-welld zone, ipayipi lensimbi elinezinwele kanye nepayipi lensimbi engenamthungo kungahlukaniswa ngokunembile.
2. Indlela yokugqwala
Esezinhlelweni zokusebenzisa indlela yokugqwala yokuhlukanisa amapayipi ensimbi anama-welded kanye namapayipi ensimbi angenamthungo, i-Weld yepayipi lensimbi esetshenzisiwe kufanele likhishwe. Ngemuva kokuba i-polishing isiqediwe, amamaki wokupholisa kufanele abonakale. Ngemuva kwalokho, ubuso bokuphela bubunjiwe nge-sandpaper e-weld, futhi ubuso bokuphela buphathwa ngesixazululo esingu-5% se-nitric acof. Uma kuvela ama-weld asobala, kungafakazelwa ukuthi ipayipi lensimbi liyipayipi lensimbi elinezinwele. Akukho mehluko osobala ekupheleni kobuso bepayipi lensimbi engenamthungo ngemuva kokugqwala.
3. Hlukanisa amapayipi ensimbi anezinwele namapayipi ensimbi angenamthungo ngokuya ngenqubo
Enqubweni yokuhlukanisaAmapayipi ensimbi akhiwekanye namapayipi ensimbi angenamthungo ngokwenqubo, wonke amapayipi ensimbi anezinwele afakwa ngokusho kwezinqubo ezinjengokugibela okubandayo nokukhishwa. Ngaphezu kwalokho, lapho imvamisa ephezulu, amapayipi we-welding we-arlding aphansi asetshenziselwa ukumelana namapayipi we-welding we-welld, kuzokwakhiwa amapayipi e-welding e-spiral selding, okuzokwakha amapayipi ensimbi ayindilinga, amapayipi ensimbi esikwele, i-oval steel Amapayipi, amapayipi ensimbi ezingunxantathu, amapayipi ensimbi e-hexagonal, amapayipi ensimbi anezinwele, amapayipi ensimbi octagonal, namapayipi ensimbi ayinkimbinkimbi. Ngamafuphi, izinqubo ezahlukahlukene zizokwakha amapayipi ensimbi ezimo ezahlukahlukene, ukuze amapayipi ensimbi anezinwele ezinama-welded kanye namapayipi ensimbi angenamthungo angahlukaniswa ngokusobala. Kodwa-ke, kwinqubo yokuhlukanisa amapayipi ensimbi angenamthungo ngokwenqubo, ikakhulukazi ahlukaniswa ngokuya ngezindlela ezishisayo zokwelashwa ezishisayo, futhi amapayipi ensimbi angenamthungo nawo anamaphayiphu wensimbi ashushulule asongelayo kanye nokubanda- amapayipi ensimbi engenamthungo. Amapayipi ensimbi asongelwe ashisekile akhiwa nge-persoration, ukugoqa kanye nezinye izinqubo, ikakhulukazi amapayipi amakhulu anomthungo kanye namapayipi ensimbi athambile afakwa yile nqubo; Amapayipi adonswe amakhaza akhiwa umdwebo obandayo wamapayipi, futhi amandla ento ebonakalayo aphansi, kepha izindawo zalo zangaphandle nezingaphakathi zibushelelezi.
