Uhlolojikelele lwepayipi yensimbi ye-alloy

Ipayipi Lensimbi Lengxubevange lisetshenziswa ezinhlelweni ezidinga izakhiwo zokumelana nokugqwala okusesilinganisweni ezihlala isikhathi eside futhi ngezindleko ezongayo. Ukukubeka nje, amapayipi e-alloy akhethwa kulezo zindawo lapho amapayipi ensimbi e-carbon angahluleka khona. Kunezigaba ezimbili zezinsimbi ze-alloy - ama-alloys aphezulu nezinsimbi eziphansi ze-alloy. Amapayipi akha ama-low alloy steels anokuqukethwe kwe-alloying okungaphansi kuka-5%. Nakuba okuqukethwe kwe-alloying yensimbi ephezulu ye-alloy kungaba phakathi kuka-5% kuya cishe ku-50%. Ngokufana nama-alloy amaningi amandla okucindezela okusebenzayo kwepayipi lensimbi engenasici licishe libe ngama-20% ngaphezu kwepayipi elishiselwe. Ngakho-ke ezinhlelweni ezinomfutho ophakeme wokusebenza njengemfuneko, ukusetshenziswa kwepayipi elingenamthungo kuyafaneleka. Nakuba linamandla kunepayipi elishiselwe, izindleko ziphakeme kakhulu. Ngaphezu kwalokho, ubungozi bokugqwala kwe-intergranular endaweni yokushisela ethintekile kumkhiqizo oshiselwe kakhulu. Umehluko obonakalayo phakathi kwe-Alloy Steel Welded Pipe kanye nomkhiqizo ongenamthungo umthungo we-latitudinal ngobude bepayipi. Kodwa-ke, namuhla, ngokuthuthuka kwezobuchwepheshe, umthungo okhona ku-Alloy Steel ERW Pipe ungancishiswa kakhulu ngendlela yokwelapha ngaphezulu, ukuze uhlale ungabonakali emehlweni abantu.
