Isishwankathelo sombhobho wentsimbi yealloyi

I-Alloy Steel Pipe isetyenziswa kwizicelo ezifuna iipropathi zokumelana ne-corrosion ephakathi kunye nokuqina okuhle kunye neendleko zoqoqosho. Ukuyibeka ngokulula, iipayipi ze-alloy zikhethwa kuloo mimandla apho iibhobho ze-carbon steel zingaphumeleli. Kukho iiklasi ezimbini zeentsimbi ze-alloy - i-alloys ephezulu kunye ne-low alloy steels. Imibhobho eyenza i-alloy steels ephantsi inomxholo we-alloying ongaphantsi kwe-5%. Ngelixa umxholo wengxubevange yentsimbi ephezulu yealloy ungahluka phakathi kwe-5% ukuya malunga nama-50%. Ngokufana ne-alloys ezininzi amandla oxinzelelo osebenzayo we-Alloy Steel Seamless Pipe malunga ne-20% ephezulu kunombhobho odityanisiweyo. Ngoko kwizicelo ezinoxinzelelo oluphezulu lokusebenza njengento efunekayo, ukusetyenziswa kombhobho ongenamthungo kuyafaneleka. Nangona unamandla kunombhobho odityanisiweyo, ixabiso liphezulu kakhulu. Ngaphaya koko, umngcipheko we-intergranular corrosion kwindawo ye-weld echaphazelekileyo ungaphezulu kwimveliso edibeneyo. Umahluko obonakalayo phakathi kwe-Alloy Steel Welded Pipe kunye nemveliso engenamthungo yi-latitudinal seam kunye nobude bombhobho. Nangona kunjalo, namhlanje, ngokuhambela phambili kwezobuchwephesha, umthungo okhoyo kwi-Alloy Steel ERW Pipe unokuncitshiswa kakhulu ngendlela yonyango olungaphezulu, ukuze uhlale ungabonakali emehlweni abantu.
