Ipayipi Elingenamthungo le-A106
Ipayipi lensimbi elingenamthungo le-ASTM A106 liyipayipi lensimbi elingenamthungo elijwayelekile laseMelika elenziwe ngochungechunge lwensimbi yekhabhoni olujwayelekile.
Isingeniso Somkhiqizo
Ipayipi lensimbi elingenamthungo le-ASTM A106 liyipayipi lensimbi elingenamthungo elenziwe ngezinto zensimbi yekhabhoni ezijwayelekile zaseMelika. Liwumugqa omude wensimbi onengxenye engenalutho futhi engenazo izihlanganisi ezizungeze umngcele. Amapayipi ensimbi anengxenye engenalutho futhi asetshenziswa kabanzi njengamapayipi okuthutha uketshezi, ngokuvamile ezindaweni ezishisa kakhulu nezinomfutho ophezulu. Amapayipi ensimbi angenamthungo e-ASTM A106 angahlukaniswa ngamapayipi ashisayo, amapayipi abandayo, amapayipi adonswayo, amapayipi akhishwe, njll. ngokwezindlela ezahlukene zokukhiqiza. Amapayipi ashisayo angenamthungo ngokuvamile akhiqizwa kumayunithi okugoqa amapayipi azenzakalelayo. Ipayipi eliqinile liyahlolwa futhi amaphutha obuso ayasuswa, asikwe ngobude obudingekayo, agxile ebusweni bokuphela kwepayipi elingenalutho, bese ethunyelwa esithandweni sokushisa ukuze lifudumale, bese libhobozwa emshinini wokubhoboza. Ngesikhathi sokubhoboza, ipayipi lijikeleza njalo futhi liqhubekela phambili, futhi ngaphansi kwesenzo se-rolling mill kanye nengaphezulu, kwakheka kancane kancane imbobo ngaphakathi kwepayipi elonakele, elibizwa ngokuthi ipayipi le-capillary. Ngemuva kwalokho ithunyelwa emshinini wokugoqa amapayipi okuzenzakalelayo ukuze iqhubeke nokugoqa, bese ubukhulu bodonga bulungiswa ngokulinganayo kuwo wonke umshini. Umshini wokulinganisa usetshenziselwa ukulinganisa ukuze kuhlangatshezwane nezidingo ezijwayelekile. Ukusetshenziswa komshini wokugoqa oqhubekayo ukukhiqiza amapayipi angenamthungo e-ASTM A106 ashisayo kuyindlela ethuthukisiwe. Amapayipi angenamthungo e-ASTM A106 anezinhlelo zokusebenza eziningi, ezisetshenziswa kakhulu njengamapayipi noma izingxenye zesakhiwo zokuthutha uketshezi. Lezi zinqubo ezimbili ziyahlukahluka ngokuya ngokunemba, ikhwalithi yendawo, usayizi omncane, izakhiwo zemishini, kanye nesakhiwo esincane.
Ukusebenza kwemishini
| Ipayipi lensimbi elingenamthungo elijwayelekile | Ibanga lepayipi lensimbi | Amandla okudonsa (i-MPA) | Amandla okukhiqiza (i-MPA) |
| I-ASTM A106 | A | ≥330 | ≥205 |
| B | ≥415 | ≥240 | |

Ipayipi lensimbi elingenamthungo le-ASTM A106Gr.B liyinsimbi ephansi yekhabhoni esetshenziswa kabanzi, esetshenziswa kabanzi embonini kaphethiloli, amakhemikhali kanye nebhoyila. Le nto inezakhiwo ezinhle zemishini. Ipayipi lensimbi le-A106-B lilingana nepayipi lensimbi elingenamthungo lensimbi lezwe lami elingama-20, futhi lisebenzisa indinganiso yepayipi lensimbi engenamthungo le-ASTM A106/A106M elishisa kakhulu, ibanga B. Lingabonakala kusukela endinganisweni yepayipi le-ASME B31.3 lesitshalo samakhemikhali kanye nepayipi lokuhlanza uwoyela: Ububanzi bokushisa bokusetshenziswa kwezinto ze-A106: -28.9~565℃.
Ipayipi lensimbi elingenamthungo elijwayelekile i-ASTM A53, elifanele izinhlelo zamapayipi okucindezela, amapayipi amapayipi kanye namapayipi okusetshenziswa ajwayelekile anamazinga okushisa angaphansi kuka-350°C.
Ipayipi lensimbi elingenamthungo i-ASTM A106 lokusebenza kwezinga lokushisa eliphezulu, elifanele izinga lokushisa eliphezulu. Lihambisana nepayipi lensimbi elijwayelekile likazwelonke elinguNombolo 20.
I-ASTM iyindinganiso ye-American Materials Association, ehlukile endleleni yokuhlukaniswa kwekhaya, ngakho-ke ayikho indinganiso eqinile ehambisanayo. Kunezinhlobo eziningi zemikhiqizo ngaphansi kwemodeli efanayo, kuye ngokuthi usebenzisa kanjani.
Ipayipi lensimbi elingenamthungo le-ASTM A106 lihlanganisa izinqubo ezimbili: ukudweba okubandayo kanye nokugoqa okushisayo. Ngaphezu kwezinqubo ezahlukene zokukhiqiza, lezi ezimbili zihlukile ngokunemba, ikhwalithi yobuso, usayizi omncane, izakhiwo zemishini, kanye nesakhiwo senhlangano. Lisetshenziswa kabanzi ezimbonini ezahlukahlukene ezifana ne-petroleum, imboni yamakhemikhali, ama-boiler, iziteshi zamandla, imikhumbi, ukukhiqizwa kwemishini, izimoto, izindiza, izindiza, amandla, i-geology, ukwakhiwa, kanye nemboni yezempi.
