Sucker Rod Kwa mafakitale aku China

C-kalasi yapamwamba kwambiri ya carbon steel ndodo imapangidwa ndi SSYD-1 (yofanana ndi AISI1526), ​​yokhala ndi mphamvu zolimbitsa thupi, pulasitiki yabwino, gawo lotsutsana ndi dzimbiri ndi zina zenizeni za chilengedwe cha sing'anga ya acidic popanda kuchititsa kupsinjika kwa sulfide.Woyamwitsa wa Grade D amapangidwa ndi zitsulo zamtengo wapatali za Cr-Mo 30CrMoA (zofanana ndi AISI 4130), zokhala ndi mphamvu zambiri, pulasitiki yabwino, moyo wautali ndi zina, zomwe zimagwiritsidwa ntchito kumalo osawononga kapena owononga pang'ono a zitsime zakuya.Ndodo zoyamwitsa za Grade K zimapangidwa ndi chitsulo chapamwamba cha Ni-Mo alloy structural 20Ni2MoA (chofanana ndi AISI 4620), chokhala ndi mphamvu zolimbitsa, ductility yabwino, kukana dzimbiri ndi mawonekedwe ena, oyenera kugwiritsidwa ntchito ponyamula katundu wopepuka komanso zitsime zosaya pamaso. za corrosive media.

Malinga ndi mapangidwe amtundu wa API, mipiringidzo yozama imapangidwa ndi chitsulo chapamwamba cha carbon kapena alloy steel.Mapeto onsewa ali ndi ulusi wakunja womwewo.Malinga ndi muyezo muyezo, iwo anawagawa 1 ndi 2, amene akhoza chikugwirizana ndi kumtunda mapeto a ndodo bwino, kapena m'munsi mapeto a mafuta bwino sucker ndodo komanso.
