Ezweni lokukhiqizwa kwamapayipi ensimbi, ukuqonda imininingwane nezindinganiso zemboni kubalulekile ekuqinisekiseni ikhwalithi nokusebenza. Elinye lamazinga anjalo yi-ASTM A139, echaza izidingo zepayipi lensimbi elihlanganisiwe likagesi (i-arc) ukuze lisetshenziswe ngomfutho ophezulu. Le bhulogi izohlola ngokujulile imininingwane ebalulekile ye-ASTM A139 futhi ihlole ukusetshenziswa kwayo, ikakhulukazi kumongo wepayipi lensimbi elijikelezayo le-S235 J0 elikhiqizwe ngumkhiqizi ohamba phambili eCangzhou, eSifundazweni saseHebei.
Imininingwane eyinhloko ye-ASTM A139
I-ASTM A139ihlanganisa izici eziningana ezibalulekile zokukhiqizwa kwamapayipi ensimbi, okuhlanganisa ukwakheka kwezinto, izakhiwo zemishini, kanye nezindlela zokuhlola. Indinganiso igxile kulezi zincazelo ezilandelayo:
1. Ukwakheka Kwezinto: I-ASTM A139 icacisa ukwakheka kwamakhemikhali ensimbi esetshenziselwa ukwenza amapayipi. Lokhu kufaka phakathi imikhawulo evumelekile yezinto ezifana nekhabhoni, i-manganese, i-phosphorus, ne-sulfur ukuqinisekisa ukuthi amapayipi anamandla nokuqina okudingekayo.
2. Izakhiwo Zomshini: Le ndinganiso ichaza izakhiwo zomshini ezidingekayo, okuhlanganisa amandla okukhiqiza, amandla okudonsa, kanye nokwelulwa. Lezi zakhiwo zibalulekile ukuqinisekisa ukuthi ipayipi lingakwazi ukumelana nokusetshenziswa komfutho ophezulu ngaphandle kokwehluleka.
3. Izidingo zokushisela: Njengoba i-ASTM A139 isebenzisana namapayipi okushisela, ifaka imininingwane yenqubo yokushisela, okuhlanganisa uhlobo lokushisela, ikhwalithi yokushisela, kanye nezindlela zokuhlola ukuqinisekisa ukuthi ukushisela kuyahlangabezana nezindinganiso ezidingekayo.
4. Izindlela Zokuhlola: Indinganiso iphinde ichaze izindlela zokuhlola okumele zisetshenziswe ukuqinisekisa ikhwalithi kanye nokusebenza kwephayiphi. Lokhu kufaka phakathi amasu okuhlola angabhubhisi ukuthola noma yiziphi iziphambeko kuma-weld noma ezintweni zephayiphi.
Ukusetshenziswa kwepayipi lensimbi le-ASTM A139
Ukusetshenziswa kwamapayipi ensimbi e-ASTM A139 kubanzi futhi kuyahlukahluka, ikakhulukazi ezimbonini ezidinga izinhlelo zamapayipi anomfutho ophezulu. Lawa mapayipi avame ukusetshenziselwa:
- Imboni Kawoyela Negesi: Amapayipi e-ASTM A139 afaneleka kakhulu ekuthuthweni kukawoyela negesi ngenxa yekhono lawo lokubekezelela ukucindezeleka okuphezulu kanye nezimo zemvelo ezinzima.
- Izinhlelo Zokuphakelwa Kwamanzi: Ukuqina nokuqina kwala mapayipi kuwenza afaneleke ukusetshenziswa ezinhlelweni zokuphakelwa kwamanzi nokusabalalisa, okuqinisekisa ukugeleza kwamanzi okuthembekile.
- Ukucubungula Amakhemikhali: Ezitshalweni zamakhemikhali, amapayipi angaphansi kwezinto ezibolayo kanti amapayipi e-ASTM A139 ahlinzeka ngokumelana nokuthembeka okudingekayo.
Izinzuzo ze-S235 J0ipayipi lensimbi elijikelezayo
Omunye wemikhiqizo evelele ekhiqizwe yinkampani yethu eCangzhou yipayipi lensimbi eliyindilinga le-S235 J0. Lo mkhiqizo uphawuleka kakhulu ngokuguquguquka kwawo kobubanzi kanye nokucaciswa kobukhulu bodonga. Ukuzivumelanisa nezimo kokukhiqiza kwenza ukwazi ukukhiqiza amapayipi abiyelwe ngodonga oluqinile aphezulu ahlangabezana nezidingo ezahlukahlukene zezimboni ezahlukahlukene.
Yasungulwa ngo-1993, ngemva kweminyaka yentuthuko esheshayo, inkampani manje ihlanganisa indawo engamamitha-skwele angu-350,000, inempahla ephelele engu-RMB 680 million, futhi inabasebenzi abazinikele abangu-680, abazibophezele ekukhiqizeni amapayipi ensimbi asezingeni eliphezulu ahlangabezana nezindinganiso zomhlaba wonke njenge-ASTM A139.
Ekuphetheni
Ukuqonda i-ASTM A139 kanye nemininingwane yayo kubalulekile kunoma ubani ohilelekile ekukhiqizeni amapayipi ensimbi. Le nqubo ayiqinisekisi nje kuphela ikhwalithi nokusebenza kwepayipi, kodwa futhi ivula izinhlelo zokusebenza eziningi ezimbonini ezahlukahlukene. Ngemikhiqizo efana nepayipi lensimbi elijikelezayo le-S235 J0, inkampani yethu iyaqhubeka nokuhola indlela ekuhlinzekeni amakhasimende ngezixazululo eziguquguqukayo nezisezingeni eliphezulu. Kungakhathaliseki ukuthi usembonini kawoyela negesi, ekuhlinzekweni kwamanzi noma ekucutshungulweni kwamakhemikhali, amapayipi ethu ensimbi azohlangabezana nezidingo zakho futhi adlule okulindelwe.
