Mhedziso ye alloy simbi pombi

An Alloy Steel Pipe inoshandiswa mumashandisirwo anoda pakati nepakati corrosion resistance zvivakwa nekusimba kwakanaka uye nemutengo wehupfumi. Kungozvitaura, alloy mapaipi anosarudzwa munzvimbo idzo umo kabhoni simbi mapaipi anogona kutadza. Kune makirasi maviri esimbi alloy - yakakwirira alloys uye yakaderera alloy simbi. Mapombi anoumba low alloy steels ane alloying content inodzika pazasi pe5%. Nepo iyo alloying yemukati yeyakakwira alloy simbi yaizosvika pakati pe5% kusvika pa50%. Zvakafanana nemaaloyi mazhinji simba rekushanda rekumanikidza kweAlloy Steel Seamless Pipe inenge 20% yakakwirira kupfuura pombi yakasungwa. Saka mumashandisirwo ane yakanyanya kumanikidza kushanda sechinhu chinodiwa, kushandiswa kwepombi isina musono kunoruramiswa. Kunyange zvazvo yakasimba kudarika pombi yakasungwa, mutengo wacho wakakwira zvikuru. Uyezve, njodzi ye intergranular corrosion pakupisa yakakanganisika weld zone yakawanda mune yakashongedzwa chigadzirwa. Musiyano unoonekwa pakati peAlloy Steel Welded Pipe uye chigadzirwa chisina musono ndiyo latitudinal seam pamwe nehurefu hwepombi. Nekudaro, nhasi, nekufambira mberi kwehunyanzvi, musono uripo paAlloy Steel ERW Pipe inogona kudzikiswa zvakanyanya kuburikidza nenzira yekurapa pamusoro, zvekuti inoramba isingaonekwe nemeso evanhu.
