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.
Imininingwane Yomkhiqizo
| Ukucaciswa | I-ASTM A333/ASME SA333 |
| Uhlobo | Kushiswe Okugoqiwe/Kubandayo |
| Usayizi Wobubanzi Bangaphandle | 1/4″NB UKUYA KU-30″NB(Usayizi Wezimbobo Ezivamile) |
| Ukuqina Kwezindonga | Ishejula 20 Ukushejula i-XXS(Kusinda Kakhulu Esicelweni) Kufikela ku-250 mm Ukuqina |
| Ubude | Amamitha angu-5 ukuya kwangu-7, amamitha angu-09 ukuya kwangu-13, ubude obungahleliwe obubodwa, ubude obuphindwe kabili obungahleliwe kanye nokwenza ngendlela oyifisayo usayizi. |
| Ipayipi Iyaphela | I-Plain Ends/Beveled Ends/i-threaded Ends/Coupling |
| I-Surface Coating | I-Epoxy Coating/Colour Paint Coating/3LPE Coating. |

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.

I-Jiangsu Hangdong Metal Products Co., Ltd. iyingxenye ye-Jiangsu Hangdong Iron & Steel Group Co., LTD. Ingabe ucwaningo kanye nentuthuko, ukukhiqizwa, yokuthengisa, isevisi kwelinye professional metal amabhizinisi production impahla. Imigqa yokukhiqiza eyi-10. Ikomkhulu liseDolobheni laseWuxi, eSifundazweni saseJiangsu ngokuhambisana nomqondo wentuthuko othi “ikhwalithi inqoba umhlaba, izimpumelelo zesevisi ikusasa”. Sizibophezele ekulawuleni ikhwalithi okuqinile kanye nenkonzo ecabangelayo. Ngemva kweminyaka engaphezu kweshumi yokwakhiwa nokuthuthukiswa, sesibe ibhizinisi elididiyelwe elididiyelwe lokukhiqiza impahla yensimbi.Uma udinga izinsizakalo ezihlobene, sicela uthinte:info8@zt-steel.cn
