{{01.}} Dab tsi yog qhov sib txawv ntawm ERW thiab seamless casing? **
* ** ERW casing: ** Tsim los ntawm Rolling Steel Sawb / shrding rau ntawm cov yeeb nkab {} Nws feem ntau cov khoom siv hluav taws xob thiab haum rau ntau cov ntawv thov.
* ** SEAMLESS CASING: ** Tsim los ntawm tho cov khoom siv holld, thiab phab ntsa qis dua, thiab muaj kev sib luag zoo dua qub cov xwm txheej . Nws yog feem ntau kim tshaj li erw casing {}}
{{0 {}}} ** Dab tsi yog cov yeeb nkab cas? **
* A ** cov yeeb nkab cas ** yog qhov loj-txoj kab hlau siv los ua cov kab laum lub qhov cub {}} nws lub hom phiaj tseem ceeb yog:
* Tiv thaiv lub borehole los ntawm collapsing .
* Cais tawm cov qauv sib txawv ntawm cov kev tsim tawm hauv qab (e {.}}}}}}}}, kev tiv thaiv dej hauv cov roj / roj cheeb tsam).
* Kev cob qhia rau cov cuab yeej drilling thiab ntau lawm tubing .
* Kev tiv thaiv cov dej hauv av .
* Muab cov qauv txheej txheem rau Wellheads thiab Blinkout tiv thaiv .
* Casing yog feem ntau siv nyob rau hauv cov roj thiab roj zoo, dej zoo, thiab hom kev sib txuas, thiab hom kev sib txuas (xov txuas).
{{0 {{}}} ** Dab tsi yog lub yeeb nkab seamless? **
* A ** Seamless Yeeb ** Yog cov yeeb nkab vuam ntawm cov hlau (plhaub) los tsim kom muaj lub taub hau hollow (plhaub) Kev tsis muaj ntawm Weld ua rau nws muaj zog thiab ntau yam kev sib tw, cov khoom siv tseem ceeb, kev ua kom muaj zog, thiab kev siv tshuaj lom neeg mob siab, thiab cov khoom siv hluav taws xob ntau}
{{0 {}}}} ** Dab tsi yog erw casing yeeb nkab? **
* A ** ERW (hluav taws xob tiv thaiv welded) Casing cov kab hlau uas muaj hluav taws xob ua ke los ntawm cov hluav taws xob hluav taws xob tau tsim los ntawm cov hluav taws xob hluav taws xob ua ke los ntawm cov npoo hlau ua kom sov, ua rau lawv yaj thiab fuse ua ke hauv qab siab . Ehrw casing yog cov kev siv hluav taws xob zoo dua qub, thiab cov qauv kev sib raug zoo uas tsis muaj kev sib raug zoo .
{{0 {{}}}} Dab tsi yog qhov sib txawv ntawm ERW thiab MS YEEB NKAB? **
* ** ERW cov yeeb nkab (hluav taws xob tiv thaiv welded yeeb nkab): ** Qhov twg yog cov cim loj yog cov khoom siv tus yuam sij
* ** MS cov yeeb nkab (cov yeeb nkab me me): ** Cov khoom siv me me uas siv rau nws cov txheej txheem (MS)) (Pom) rau qhov loj uas diameters.
* ** ELW piav qhia txog * Yuav ua li cas * cov yeeb nkab tau piav qhia los ntawm MS cov yeeb nkab)}. Cov pa roj hmab) {1, Cov hlau, tsis yog me hlau me .}} Tseem zoo, ERW yog * cov khoom * {{5} {5}
