Yiziphi izakhiwo ze-elbows engamelana nokugqokwa?

1. Ukuvikelwa okuhle
Ngoba ukufakwa kwangaphakathi kwepayipi le-ceramic composite yi-ceramic ceramic (A-AL2O3), ubulukhuni be-mohs bungafinyelela ku-9.0, okulingana ngenhla kwe-HRC90. Ngakho-ke, inokuvikelwa okuphezulu kwemithombo yezindaba ebabazekayo ethuthelwe ku-metallurgy, amandla kagesi, izimayini, amalahle kanye nezinye izimboni. Kuqinisekisiwe ukuhlinzwa kwezimboni ukuthi impilo yayo yokugqoka ine-times yayo izikhathi eziyishumi noma ngisho nezikhathi eziningi zensimbi elukhuni.
2. Ukuphikiswa okuncane okusebenzayo
Ipayipi eliyinhlanganisela ye-SHS ceramic linendawo ebushelelezi yangaphakathi futhi ayikaze igcwale, futhi ayinayo i-Helvex helix endaweni yangaphakathi yepayipi lensimbi engenamthungo. Ngokokuhlola ubulukhuni bendawo yangaphakathi kanye nezimpawu ezihlanzekile zokumelana kwamanzi ngamayunithi afanele wokuhlola, ubushelelezi bangaphakathi bungcono kunanoma iyiphi ipayipi lensimbi, futhi i-coeffient ecacile yokuphikiswa iyi-0.0193, ephansi kancane kunamapayipi angenamthungo. Ngakho-ke, ishubhu inezimpawu zokuphikiswa okuncane kokugijima futhi inganciphisa izindleko zokusebenza.
3. Ukulwa nokubhuka nokulwa nokulwa
Njengoba ungqimba lwensimbi yensimbi yensimbi (A-Al2o3), kuyisici esingathathi hlangothi. Ngakho-ke, ine-acid kanye ne-alkali yokumelana nokumelana nokuqina kwamanzi olwandle, futhi futhi inokulwa nezinye izikali nezinye izici.
4. Ukusebenza okuhle
Ngoba i-Corundum Ceramic (A-AL2O3) isakhiwo esisodwa esizinzile se-crystal. Ngakho-ke, ipayipi eliyinhlanganisela lingasebenza ngokujwayelekile isikhathi eside kububanzi bezinga lokushisa le-50-5900 degree. Ukwandiswa kokwenyuka okuqondile kwezinto ezibonakalayo kungu-6-8 × 10-6 / 0c, okungo-1/2 wepayipi lensimbi. Izinto ezibonakalayo zinokuqina okuhle okushisayo.
I-5. Izindleko zobunjiniyela eziphansi
Amapayipi ahlanganisiwe we-Ceramic akwesobunxele futhi angabizi. Kulula ama-50% kunamapayipi e-cast tshe anobubanzi obufanayo bangaphakathi; I-20-30% elula kune-alloy egqoke ama-alloy avimbela, futhi inokumelana kahle nokumelana nokugqwala. Izindleko zokusebenza ziyancishiswa. Ngokusho kokuqhathanisa phakathi kwesabelomali sephrojekthi kanye nephrojekthi yangempela yezikhungo zokwakhiwa kanye namayunithi wokwakha, izindleko zephrojekthi zepayipi zilingana netshe le-poroy, futhi kuqhathaniswa nepayipi le-alloy elingamelana nalo, izindleko zephrojekthi zincishiswa cishe ngama-20%.
6. Ukufakwa okulula nokwakha
Ngoba ishubhu likhanya ngesisindo futhi linokusebenza okuhle kwe-welding. Ngakho-ke, i-welding, i-flange, ukuhlangana okusheshayo nezinye izindlela zingasetshenziswa, okulungele ukwakhiwa nokufakwa, futhi kunganciphisa izindleko zokufaka.
