1. Ukubuka konke kwe-ASTM A213 T5 Alloy Steel Tubing
I-ASTM A213 T5 iyibanga lensimbi ye-chromium-molybdenum alloy eyenzelweisevisi yokushisa okuphezulu kanye nokucindezela okuphezulukuma-boiler, ama-superheater, kanye nama-heat exchanger. Ukwengezwa kwe-chromium kanye ne-molybdenum kuthuthukisa kakhulu ukumelana ne-oxidation, amandla okuhamba, kanye nokuqina kwesakhiwo emazingeni okushisa aphezulu. Ngenxa yalezi zakhiwo, amashubhu e-T5 asetshenziswa kabanzi ekukhiqizeni ugesi, ezitshalweni ze-petrochemical, ezindaweni zokuhluza, nakwezinye izindawo ezishisayo ezidingayo.
At Insimbi YaseWomic, Amashubhu e-ASTM A213 T5 akhiqizwa ngaphansi kwezinhlelo zokulawula ikhwalithi eziqinile futhi ahlinzekwa ngokuhambisana nezindinganiso zomhlaba wonke. Ukukhiqiza kwethu kuhambisana neIzidingo ze-ASTM A213 / ASME SA213, futhi izinto zingalethwa ngeIsitifiketi se-EN 10204 3.1 noma 3.2. Kumaphrojekthi emishini yokucindezela yaseYurophu, siphinde sinikeze imikhiqizo ehambisana ne-I-PED (Isiqondiso Semishini Yokucindezela) 2014/68/EUngemibhalo ephelele yokulandelela kanye nokuhlolwa.
Njengoba inezindawo zokukhiqiza ezithuthukisiwe kanye neziteshi zokuhlinzeka ngezinto zokusetshenziswa ezizinzile, i-Womic Steel iqinisekisa ikhwalithi yomkhiqizo ethembekile, ukwenza ngokwezifiso okuguquguqukayo, kanye nokulethwa okuphumelelayo emhlabeni jikelele.
