Amapayipi Ahlanganisiwe Ajikelezayo Amapayipi Kagesi Angaphansi Komhlaba EN10219

Amapayipi Ahlanganisiwe Ajikelezayo Amapayipi Kaphethiloli Angaphansi Komhlaba EN10219 Isithombe Esivelele

Incazelo emfushane:

Sethula amapayipi ethu ahlanganisiwe asezingeni eliphezulu, aklanyelwe ukuhlangabezana nezidingo ezidingekayo zokufakwa kwamapayipi egesi angaphansi komhlaba. Lawa mapayipi akhiqizwa ngokucophelela ngokwezindinganiso eziqinile ezibekwe ku-EN10219, okuqinisekisa izidingo zokulethwa kobuchwepheshe eziphezulu kakhulu zezingxenye ezingenalutho ezakhiwe ngokuhlanganisiwe ezibandayo ezinsimbini ezingezona i-alloy kanye nezinsimbi ezincane.

Imininingwane Yomkhiqizo

Amathegi Omkhiqizo

Okwethuamapayipi ahlanganisiwe ajikelezayoziyisixazululo esifanele samaphrojekthi lapho ukumelana nokugqwala kanye nobuqotho besakhiwo kubalulekile khona. Inqubo ehlukile yokushisela ejikelezayo ayigcini nje ngokuthuthukisa amandla epayipi, kodwa futhi ihlinzeka ngomphezulu ongenamthungo, inciphisa ingozi yokuvuza nokwehluleka. Lokhu kuzenza zifaneleke kakhulu ezindaweni ezinzima ezivame ukuhlangatshezwana nazo ekusetshenzisweni komhlaba.

Izinga le-EN10219 liqinisekisa ukuthi amapayipi ethu akhiqizwa ngokunemba nangekhwalithi, okuqinisekisa ukuthi angakwazi ukumelana nezingcindezi nezinselele zokuthuthwa kwegesi yemvelo. Njengoba egxile ekuqineni nasekuthembekeni, amapayipi ethu ahlanganisiwe nge-spiral aklanyelwe ukunikeza ukusebenza okuhlala isikhathi eside, okunciphisa isidingo sokulungiswa nokufakwa esikhundleni njalo.

a. Indlela yokususa i-oxidation ichazwa kanje:FF: Insimbi ebulewe ngokuphelele equkethe izinto zokubopha i-nitrogen ngamanani anele ukubopha i-nitrogen etholakalayo (isb. ubuncane be-0,020% iyonke i-Al noma i-0,015% i-Al encibilikayo). b. Inani eliphezulu le-nitrogen alisebenzi uma ukwakheka kwamakhemikhali kubonisa okuqukethwe okungenani kwe-Al okungu-0,020% kanye nesilinganiso esincane se-Al/N esingu-2:1, noma uma kukhona ezinye izinto ezibophayo ze-N ezanele. Izinto ezibophayo ze-N kufanele ziqoshwe kuDokhumenti Yokuhlola.

Ngaphezu kokwakhiwa kwawo okuqinile, la mapayipi alula futhi kulula ukuwaphatha, okwenza ukufakwa kube ngcono futhi kube ngcono. Kungakhathaliseki ukuthi wenza iphrojekthi entsha yamapayipi noma uthuthukisa uhlelo olukhona, amapayipi ethu ahlanganisiwe ajikelezayo anikeza inhlanganisela ephelele yamandla, ukuguquguquka, kanye nokuhambisana nezindinganiso zemboni.

Khetha amapayipi ethu ahlanganisiwe ahambisana nezidingo zakho zamapayipi egesi angaphansi komhlaba bese uzwa ukuthula kwengqondo okuza nokusebenzisa imikhiqizo ehlangabezana nezidingo zakho.EN10219amazinga. Themba ukuzibophezela kwethu ekhwalithini nasekusebenzeni ukuqinisekisa ukuphepha nokusebenza kahle kwengqalasizinda yakho yegesi.

Okwedlule: Amapayipi Ensimbi Yekhabhoni Ehlanganisiwe Ejikelezayo Yamapayipi Egesi Yemvelo Angaphansi Komhlaba - EN10219

Olandelayo: Ipayipi Lensimbi Eligoqekile le-A252 Lebanga 1 Lokwakha Okuhlala Isikhathi Eside
