I-ASTM A333 Ipayipi Lensimbi Elingenamthungo Eliphansi Lokushisa Okuphansi
Isingeniso somkhiqizo
I-ASTM A333 iyisimiso esijwayelekile esinikezwa wonke amapayipi ashiselwe kanye nawensimbi angenamthungo, ikhabhoni nealloy okuhloswe ukuthi asetshenziswe ezindaweni ezisezingeni eliphansi lokushisa.Amapayipi e-ASTM A333 asetshenziswa njengamapayipi okushintshanisa ukushisa namapayipi omkhumbi wokucindezela.
Njengoba kushiwo kulesi sigaba esingenhla, ukuthi la mapayipi asetshenziswa ezindaweni lapho izinga lokushisa liphansi kakhulu, asetshenziswa ezimbonini ezinkulu zika-ayisikhilimu, izimboni zamakhemikhali nakwezinye izindawo ezinjalo.Asetshenziswa njengamapayipi okuthutha futhi ahlukaniswa ngamabanga ahlukene.Ukuhlukaniswa kwamabanga alawa mapayipi kwenziwa ezicini ezihlukahlukene ezifana nokumelana nezinga lokushisa, amandla aqinile, amandla akhiqizayo kanye nokwakheka kwamakhemikhali.Amapayipi e-ASTM A333 anikezwa amabanga ayisishiyagalolunye ahlukene aqokwe izinombolo ezilandelayo:1,3,4,6.7,8,9,10, kanye no-11.

Lawa mapayipi ane-NPS 2"kuya ku-36".Nakuba amabanga ahlukene enokuhlolwa okuhlukile kwezinga lokushisa izinga lokushisa elijwayelekile lawa mapayipi angamelana nalo lisuka ku-45 degree C, kuya ku-195 degree C. Amapayipi e-ASTM A333 kufanele enziwe ngendlela engenamthungo noma yokushisela lapho kungafanele kube khona okokugcwalisa metal ngesikhathi senqubo yokushisela.
Izinga le-ASTM A333 limboza udonga olungenamthungo futhi olushiselwe ipayipi lensimbi nengxubevange ehloselwe ukusetshenziswa emazingeni okushisa aphansi.I-ASTM A333 alloy pipe izokwenziwa inqubo engenamthungo noma yokushisela ngokungezwa kwensimbi yokugcwalisa ekusebenzeni kokushisela.Wonke amapayipi angenamthungo nashiselwe kufanele aphathwe ukuze kulawulwe ukwakheka kwawo okuncane.Ukuhlolwa kwe-tensile, ukuhlolwa komthelela, ukuhlolwa kwe-hydrostatic, nokuhlolwa kukagesi okungaboli kuzokwenziwa ngokuhambisana nezidingo ezishiwo.Abanye osayizi bomkhiqizo bangase bangatholakali ngaphansi kwalokhu kucaciswa ngenxa yokuthi ubukhulu bodonga olusindayo bunomthelela omubi ezicini zokushisa eziphansi.
Ukukhiqizwa kwamapayipi ensimbi e-ASTM A333 kufaka phakathi uchungechunge lokungapheleli okubonakalayo ukuze kuqinisekiswe ukuthi akhiwe ngendlela efanele.Ipayipi lensimbi le-ASTM A333 lizoba ngaphansi kokwenqatshwa uma ukungapheleli kwendawo okwamukelekayo kungahlakazeka, kodwa kuvela endaweni enkulu ngaphezu kwalokho okubhekwa njengokuphelela okufana nomsebenzi.Ipayipi eliqediwe kufanele liqonde ngokufanelekile.
