Njengoba kushiwo esigabeni esingenhla, ukuthi la mapayipi asetshenziswa ezindaweni lapho izinga lokushisa liphansi kakhulu, asetshenziswa ezimbonini ezinkulu ze-ayisikhilimu, ezimbonini zamakhemikhali nakwezinye izindawo ezinjalo. Asetshenziswa njengamapayipi okuthutha futhi ahlukaniswe ngamagreyidi ahlukene. Ukuhlukaniswa kwamagreyidi ala mapayipi kwenziwa ngezici ezahlukene njengokumelana nokushisa, amandla okunamathela, amandla okukhiqiza kanye nokwakheka kwamakhemikhali. Amapayipi e-ASTM A333 afakwe ngamagreyidi ayisishiyagalolunye ahlukene aqokwe yizinombolo ezilandelayo: 1, 3, 4, 6.7, 8, 9, 10, kanye no-11.
Imininingwane Yomkhiqizo

| Ubukhulu Bodonga | ishejuli 20 Ukuhlela i-XXS (Esindayo Uma Icelwa) Ubukhulu obufika ku-250 mm |
| Ubude | Amamitha angu-5 kuya kwangu-7, amamitha angu-09 kuya kwangu-13, ubude obungahleliwe obubodwa, ubude obuphindwe kabili obungahleliwe kanye nosayizi ofanele. |
| Iziphetho Zepayipi | Iziphetho Ezilula/Iziphetho Ezigobile/Iziphetho Ezinemicu/Ukuhlanganisa |
| Ukugqoka Okungaphezulu | Isimbozo se-Epoxy/Isimbozo sopende wombala/Isimbozo se-3LPE. |
| Izimo Zokulethwa | Njengoba Kugoqwe. Kugoqwe Kujwayelekile, Kugoqwe/Kwakhiwe Ngomshini Wokushisa, Kugoqwe Kujwayelekile, Kugoqwe Kujwayelekile futhi Kuthambile/Kucinyiwe futhi I-Tempered-BR/N/Q/T |
Izinga elijwayelekile le-ASTM A333 limboza ipayipi lensimbi ye-carbon ne-alloy engenamthungo nehlanganisiwe eludongeni elenzelwe ukusetshenziswa emazingeni okushisa aphansi. Ipayipi le-alloy le-ASTM A333 le-ASTM A333 kumele lenziwe ngenqubo engenamthungo noma yokushisela ngokufakwa kwensimbi yokugcwalisa ekusebenzeni kokushisela. Wonke amapayipi angenamthungo nehlanganisiwe kumele aphathwe ukulawula isakhiwo sawo esincane. Ukuhlolwa kokuqina, ukuhlolwa komthelela, ukuhlolwa kwe-hydrostatic, kanye nokuhlolwa kukagesi okungabhubhisi kufanele kwenziwe ngokuhambisana nezidingo ezibekiwe. Amanye amasayizi omkhiqizo kungenzeka angatholakali ngaphansi kwale ncazelo ngoba ubukhulu bodonga obunzima bunomthelela omubi ezimpahleni zomthelela wokushisa okuphansi.
Ukukhiqizwa kwepayipi lensimbi le-ASTM A333 kuhlanganisa uchungechunge lwezinkinga zobuso obubonakalayo ukuqinisekisa ukuthi zenziwe kahle. Ipayipi lensimbi le-ASTM A333 kufanele lilahlwe uma izinkinga zobuso ezamukelekayo zingasakazekile, kodwa zivela endaweni enkulu ngaphezu kwalokho okubhekwa njengokuqeda okufana nomsebenzi. Ipayipi eliqediwe kufanele liqonde ngokufanele.

I-Jiangsu Hangdong Metal Products Co., Ltd. iyinkampani engaphansi kwe-Jiangsu Hangdong Iron & Steel Group Co., LTD. Iyinkampani yocwaningo nentuthuko, ukukhiqiza, ukuthengisa, isevisi kwelinye lamabhizinisi ochwepheshe okukhiqiza izinto zensimbi. Imigqa yokukhiqiza eyi-10. Indlunkulu itholakala eDolobheni laseWuxi, eSifundazweni saseJiangsu ngokuhambisana nomqondo wentuthuko othi “ikhwalithi inqoba umhlaba, impumelelo yesevisi ikusasa”. Sizibophezele ekulawuleni ikhwalithi okuqinile kanye nensizakalo ecabangelayo. Ngemva kweminyaka engaphezu kweyishumi yokwakha nokuthuthukisa, sesibe yinkampani yobuchwepheshe yokukhiqiza izinto zensimbi ezihlanganisiwe. Uma udinga izinsizakalo ezihlobene, sicela uxhumane nathi:info8@zt-steel.cn
