LTCsawv rauNtev Threaded thiab Coupled. Nws yog ib hom kev sib txuas tshwj xeeb uas siv rau cov roj thiab roj zoocasingraws li txhais los ntawm covAPI 5 CTtxheem.
Precision guaranteed. Txhua qhov sib koom LTC yog ntsuas rau API 5B cov qauv.Thov ib qho piv txwv Mill Test Certificate (MTC) tam sim no.
Nov yog ib qho kev piav qhia ntawm qhov nws txhais tau li cas hauv kev xyaum:
Cov lus piav qhia
Ntev Threaded:Cov threaded seem ntawm qhov kawg ntawm cov yeeb nkab yog ntev tshaj qhov "Short" (STC) version. Qhov no muab kev sib koom tes ntau dua (ntau dua "cov hniav" xauv ua ke).
Ua ke:Cov kav dej sib txuas ua ke siv lub tes tsho cais hu ua akev sib txuas.
Cov yam ntxwv
Xov Profile:Nws yog ib8- round xov(8-RD), txhais tau tias muaj 8 threads ib nti. Cov xov muaj qhov sib npaug (sab saum toj) thiab hauv paus (hauv qab).
Tapered:Cov threads yog txiav rau ntawm ib tug taper kom lawv nruj raws li lawv tau screwed rau hauv lub coupling.
Seal Mechanism:Nws tsim ib lub foob los ntawmcuam tshuam haum. Qhov no txhais tau hais tias thaum koj nruj nws, cov threads compress rau ib leeg. Ib "xov dope" (tshuaj roj tshwj xeeb) yog siv los sau cov qhov khoob me me thiab tiv thaiv kom tsis txhob xau.
Qhov zoo ntawm LTC Xov
Kev sib koom ua ke siab dua
Piv rau STC, LTC muaj cov xov txuas ntev dua. Nrog ntau threads sib koom lub load, kev sib txuas muab lub zog tensile ntau dua, txhawb nqa cov hlua hnyav dua thiab txo qhov kev pheej hmoo ntawm"rub- tawm"(qhov twg threads strip los yog plam sib nrug).
Txhim kho sealing Performance
Thaum nws tseem tso siab rauxov dope(sealant) rau kev sib khi, txoj kab ntev ntawm txoj kev ua kom muaj zog tiv thaiv cov dej nkag. Qhov no ua rau LTC txhim khu kev qha ntawm kev tiv thaiv cov kua xau dua li cov xov luv luv.
Durability thiab yooj yim ntawm kev tuav
Cov8-Round xovprofile nta round crests thiab cov hauv paus hniav. Qhov kev tsim no tsis tshua muaj kev puas tsuaj los ntawm kev cuam tshuam me me thaum lub sijhawm ua haujlwm (piv rau cov ntse -angled threads) thiab tso cai rau kom yooj yim duaua-ua(screwing sib tov).
Tus nqi -Kev ua tau zoo
Cov nqi tsim khoom rau LTC yog qis dua rauBTC (Buttress)los yogHwm Kev Sib Txuas. Nws muaj kev ua tau zoo-rau- tus nqi piv, ua kom txaus rau feem ntau ntawm qhov nruab nrab - qhov tob txoj kev loj hlob.
Universal Compatibility
Raws li API tus qauv xov, LTC txuas thiab cov kav dej ua los ntawm API 5CT- ntawv pov thawj zeb thoob ntiaj teb tuaj yeem hloov pauv tau, ua rau kev yuav khoom thiab kev saib xyuas yooj yim heev.
Daim ntawv thov ntawm LTC Xov
Nruab nrab -Deep Wells
LTC yog siv rau qhov dej uas tshaj qhov muaj peev xwm ntawm STC tab sis tseem tsis tau xav tau lub zog tensile ntawm BTC threads. Nws yog feem ntau siv nyob rau hauv zoo seem xws li los ntawm2,000 txog 4,000 meterstob.
Txheem rau Common Steel Qib
LTC yog qhov kev sib txuas zoo tshaj plaws rau nruab nrab - zog steel qib xws liJ55, K55, thiab N80. Nws kuj nquag siv rauP110casing thaum lub axial nro thiab roj-tightness yuav tsum tsis hnyav heev.
Kua-Tight Service
Feem ntau siv nyob rau hauv cov roj crude qhov dej, dej txhaj tshuaj, thiab nto los yog nruab nrab casing hlua. Nws zoo heev ntawm kev thaiv cov roj thiab dej, txawm li cas los xijSiab -Pressure Gas Wellsfeem ntau yuav tsum tau hloov mus rau Premium Connections rau roj- nruj seal.
Standard Vertical Drilling
Qhov zoo tshaj plaws rau cov dej ntsug ntsug uas tsis muaj qhov kub thiab txias, siab siab, lossis siab torque (xws li, tsis yog - ntu kab rov tav).

FAQ
Dab tsi yog qhov txawv ntawm LTC thiab BTC xov?
Qhov tseem ceeb sib txawv yog nyob rau hauv lubthread profile thiab sib koom ua ke muaj zog.
LTCsiv ib8 - puag ncig (V-shaped)xov, muab lub zog tensile nruab nrab haum rau nruab nrab - qhov tob ntsug qhov dej.
BTCnta atrapezoidal (square -zoo li)xov, uas muaj ntau dua tensile zog thiab superior torque kuj.
Qhov txawv ntawm LTC thiab STC yog dab tsi?
Qhov txawv tseem ceeb yogxov ntev.
LTC (ntev)muaj ib tug ntev threaded cheeb tsam tshajSTC (luv luv).
Vim qhov kev koom tes ntxiv no,LTC muab lub zog tensile ntau dua, tso cai rau nws los txhawb nqa cov yeeb nkab hnyav dua.
STCyog luv dua thiab tsis muaj zog, ua rau nws tsuas yog haum rau cov qhov dej ntiav los yog qhov chaw qhov chaw uas cov load tsawg heev.
