Izinzuzo Zethu ze-ASTM A252 Steel Pipe:
· Intengo Eqhudelanayo: Sinokubambisana okuzinzile kwesikhathi eside nezimboni zempahla eluhlaza, izikhungo ezisekela ukukhiqiza ezivuthiwe neziphelele, uhlelo oluqinile lokulawula ikhwalithi, kanye nemodeli edidiyelwe egcina izindleko zethu zokukhiqiza zisezingeni eliphansi uma kuqhathaniswa.
· Isikhathi Sokulethwa Okusheshayo: Ukukhiqizwa kwamapayipi ensimbi anezincazelo ezijwayelekile kungaqedwa ngokushesha njengezinsuku eziyi-7.
· Qedela Isitifiketi: Zonke izinhlobo zezitifiketi ziyatholakala, okuhlanganisa isitifiketi se-API 5L, isitifiketi se-ISO 9001, isitifiketi se-ISO 14001, isitifiketi se-FPC, isitifiketi se-Environmental Quality System, nokunye.
· Izisetshenziswa Zokukhiqiza Ezithuthukile: Singenise imishini evela eJalimane futhi sathuthukisa ngokuzimela imishini emine yokukhiqiza.
· Ithimba Lochwepheshe: Sinabasebenzi abangaphezu kuka-300, kuhlanganise nabasebenzi bezobuchwepheshe abangaphezu kuka-60, futhi sinethimba elizimele locwaningo lwemishini.
· Izinsiza Zokuhlola Eziphelele: Sihlonyiswe ngezindawo zokuhlola ezehlukene, okuhlanganisa kodwa akugcini nje kuphela kuzitholi zokungaphumeleli ezisebenza ku-inthanethi ze-ultrasonic, umabonakude we-X-ray wezimboni nezinye izinto zokuhlola ezibalulekile.
Isicelo:
Iqembu le-Longma Ipayipi lensimbi le-ASTM A252 thola izinhlelo zokusebenza eziningi ku:
· Ingqalasizinda: Kusukela kumabhuloho nemigwaqo emikhulu kuya ezakhiweni nasezinkundleni zemidlalo, amapayipi ensimbi e-ASTM A252 adlala indima ebalulekile ekulolongeni indawo yengqalasizinda.
· Izakhiwo Zasolwandle: Ngokumelana kwawo okuphakeme nokugqwala, la mapayipi alungele izakhiwo zasolwandle, okuhlanganisa nezinsimbi, izikhumulo zemikhumbi, nezinkundla ezingasogwini.
· I-Piling: Amapayipi ensimbi e-ASTM A252 avame ukusetshenziselwa ukunqwabelanisa isisekelo kumaphrojekthi wokwakha, ahlinzeka ngokusekelwa okuzinzile kwezakhiwo ezimeni ezahlukahlukene zenhlabathi.
· Amasistimu Amanzi Nendle: Lawa mapayipi afanele amanzi kanye nezinhlelo zokukhuculula indle, ahlinzeka ngokusebenza okuthembekile nokuphila isikhathi eside ezindaweni ezifakwe ngaphansi komhlaba.
Longma Group
I-Hebei Longma Group Limited(LONGMA GROUP) ingelinye labakhiqizi bamapayipi ensimbi be-ERW/LSAW baseShayina kusukela ngo-2003, elinenhlokodolobha ebhalisiwe engu-441.8 billion, ehlanganisa indawo engamamitha-skwele angama-230000. Le nkampani igxile ekukhiqizeni: ububanzi obukhulu, obugqinsi obuqinile, izinhlangothi ezimbili, i-sub-arc-seam, ipayipi yensimbi yokushisela, i-LSAW-Longitudinal Submerged Arc Welded, amapayipi ensimbi e-ERW. Ekupheleni kuka-2023, umkhiqizo wonyaka wenkampani udlule amathani ayi-1000000.
Njengengcweti A252 ipayipi lensimbi Umkhiqizi kanye nomphakeli, u-Longma uzibophezele ekuletheni imikhiqizo esezingeni eliphezulu kanye nenkonzo ehlukile kumakhasimende ethu. Ngokugxila ekusungulweni nasekuthembekeni, silwela ukweqa esikulindele futhi sibeke izilinganiso ezintsha embonini. Ukulethwa okusheshayo kwe A252 ipayipi ngobukhulu obuhlukahlukene kanye namanani okuncintisana, xhumana no-Longma ku info@longma-group.com.
