Ntau hom Sucker Qws
API Qib Sucker Rods
Standard API sucker rods muaj nyob rau hauv ntau qib steel txhua nrog nws tus kheej cov khoom thiab daim ntawv thov:
Qib C: Rau lub teeb rau nruab nrab load daim ntawv thov nyob rau hauv lub qhov dej uas muaj txaus tiv thaiv corrosion.
Yam tsawg kawg nkaus tawm los: 414 MPa (60, 000 psi)
Tensile range: 621-793 MPa (90, 000-115, 000 psi)
Qib K: Rau lub teeb rau nruab nrab load daim ntawv thov nyob rau hauv corrosive ib puag ncig. Txawm li cas los xij, kom ntev kev pab cuam lub neej, peb pom zoo kom txaus tiv thaiv corrosion.
Yam tsawg kawg nkaus tawm los: 414 MPa (60, 000 psi)
Tensile range: 621-793 MPa (90, 000-115, 000 psi)
Qib D: Rau nruab nrab mus rau hnyav load daim ntaub ntawv nyob rau hauv lub qhov dej uas muaj txaus tiv thaiv corrosion.
Tawm tawm yam tsawg kawg nkaus: 586 MPa (115, 000 psi)
Tensile range: 793-965 MPa (115, 000-140, 000 psi)
Qib D tshwj xeeb: Ua ke cov khoom ntawm qib K thiab qib D carbon nqus cov pas nrig. Rau nruab nrab mus rau hnyav load daim ntaub ntawv nyob rau hauv corrosive ib puag ncig. Txawm li cas los xij, kom ntev kev pab cuam lub neej, peb pom zoo kom txaus tiv thaiv corrosion.

Corrosion Resistant Sucker Rods
Hauv cov dej corrosive, lub neej kev pab cuam ntawm API qib sucker rods raug txo qis, ua rau cov nqi kev pabcuam siab thiab lub sijhawm tsis muaj txiaj ntsig (NPD).
Txhawm rau txwv qhov tsis zoo ntawm kev xeb, peb tau qhia qhov tshwj xeeb nto tiav uas tiv thaiv tus pas nqus dej tiv thaiv cov kua dej lossis cov pa roj.
Txhua tus pas nrig yog tungsten alloy electroplated tshaj nws tag nrho ntev, muab nws lub zog thiab ruaj khov txheej nrog lub hardness ntawm 57 HRC-60 HRC.
Cov txheej txheem tiv thaiv zoo tiv thaiv tus pas nqus dej tiv thaiv kev puas tsuaj thiab corrosion. Hydrogen embrittlement uas ua rau lub pas nrig tsis muaj teeb meem ntxiv lawm.
High Strength Sucker Rods
Hauv cov qhov dej tob heev lossis thaum khiav cov twj muaj peev xwm loj, qhov kev thauj khoom ntau dua yog siab dhau rau tus qauv API qib sucker rods.
Sovonex ™ siab zog nqus pas nrig yog tsim tshwj xeeb los kov yeej qhov teeb meem no. Ua los ntawm cov hlau qib siab nrog lub zog tensile siab tshaj plaws ntawm 1,195 MPa (173,339 psi) thiab cov txiaj ntsig yam tsawg kawg nkaus ntawm 795 MPa (115, 000 psi), cov pas nrig hwm zoo haum rau cov ntawv thov hnyav ntxiv.
Cov nram qab no premium sucker rods muaj:
High Strength (HS): Rau kev siv hnyav rau hnyav ntxiv.
High Strength Hardened (HSH): Zoo li HS qib, tab sis nrog qhov tsawg kawg nkaus hardness ntawm 42 HRC thiab cov tub ntxhais hardness tsawg kawg yog 224 HB.
Polished Rods
Ib tug polished sucker pas nrig khiav hauv lub thawv ntim khoom thiab muab kev sib txuas ntawm lub tshuab nqus tsev twj thiab lub downhole sucker pas nrig hlua.
Furnished nrog hnav resistant thiab anti-corrosive txheej, Sovonex ™ polished rods ncav cuag 65 ntawm Rockwell "C" hardness scale (65 HRC). Qhov tshwj xeeb saum npoo tiav no txhim kho lub siab foob ntawm lub thawv ntim khoom thiab ncua kev pabcuam lub neej ntawm tus pas nrig.
