Ukubuka konke kwepayipi lensimbi ye-alloy

Ipayipi Lensimbi Ehlanganisiwe lisetshenziswa ezinhlotsheni ezidinga izakhiwo eziqinile zokumelana nokugqwala futhi ezihlala isikhathi eside futhi ngezindleko ezingabizi. Kalula nje, amapayipi ensimbi ahlanganisiwe ayathandwa kulezo zindawo lapho amapayipi ensimbi yekhabhoni angase angasebenzi khona. Kunezinhlobo ezimbili zezinsimbi zensimbi ezihlanganisiwe - izinsimbi eziphezulu kanye nezinsimbi zensimbi ezihlanganisiwe eziphansi. Amapayipi akha izinsimbi zensimbi ezihlanganisiwe eziphansi anokuqukethwe kwe-alloying okungaphansi kuka-5%. Ngenkathi okuqukethwe kwe-alloying kwensimbi ephezulu yensimbi kungasukela ku-5% kuya ku-50%. Njengama-alloyi amaningi, ikhono lokucindezela lokusebenza lepayipi lensimbi engenamthungo lensimbi ehlanganisiwe liphakeme cishe ngo-20% kunepayipi elihlanganisiwe. Ngakho-ke ezinhlotsheni ezinengcindezi yokusebenza ephezulu njengemfuneko, ukusetshenziswa kwepayipi elingenamthungo kuyafaneleka. Nakuba kunamandla kunepayipi elihlanganisiwe, izindleko ziphakeme kakhulu. Ngaphezu kwalokho, ingozi yokugqwala kwe-intergranular endaweni ye-weld ethintekile ekushiseni ingaphezulu kumkhiqizo ohlanganisiwe. Umehluko obonakalayo phakathi kwepayipi lensimbi ehlanganisiwe lensimbi ehlanganisiwe kanye nomkhiqizo ongenamthungo umthungo we-latitudinal ubude bepayipi. Kodwa-ke, namuhla, ngentuthuko kwezobuchwepheshe, umthungo okhona kwi-Alloy Steel ERW Pipe ungancishiswa kakhulu ngokusebenzisa ukwelashwa kwendawo, kangangokuthi uhlala ungabonakali emehlweni abantu.
