Isingeniso somkhiqizo
I-ASTM A333 iwukucaciswa okujwayelekile okunikezwe wonke amapayipi ashiselwe kanye nensimbi engenamthungo, 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.
