1. ** Dab tsi yog qhov txawv ntawm seamless thiab welded yeeb nkab? **
* ** SEAMLESS YEEB: ** Ua los ntawm cov khoom siv hluav taws xob hlau uas yog cov khoom siv holloled uas tsis muaj nqaws lossis welds raws nws qhov ntev. Cov yeeb nkab yog tom qab ntawd elongated thiab loj rau qhov uas yuav tsum tau ua.
* ** Welded yeeb nkab: ** Ua los ntawm dov lub tiaj tus hlau phaj lossis kauj (skelp) rau hauv cov txheej txheem vuam (zoo li ERW, pom, EFW). Qhov no tsim cov kev sib tw ntev los yog Tsom Held ntawm cov yeeb nkab ntev.
2. ** Qhov twg zoo dua seamless lossis welded yeeb nkab fittings? **
* Tsis muaj qhov tseeb "zoo dua" kev xaiv; Cov kev xaiv yog nyob ntawm daim ntawv thov yuav tsum tau ua. Seamless fittings feem ntau muaj zog thiab txhim khu kev qha ntau dua nyob rau hauv kev kub siab, kev kub siab, lossis tsis muaj kev pab cuam Weld uas yog qhov tsis muaj zog taw tes. Lawv nyiam rau cov ntawv thov xav tau xws li cov pa siab siab, hydrocarbons, lossis cov kua ntshav. Welded fittings feem ntau yuav raug nqi ntau dua thiab yooj yim muaj nyob hauv qhov loj me. Lawv zoo kawg nkaus haum thiab siv tau rau cov ntawv thov txo qis, siv cov dej, lossis tsawg dua cov kev pabcuam tseem ceeb uas tus nqi yog qhov tseem ceeb ntawm qhov nqi.
3. ** Dab tsi yog qhov txawv ntawm seamless thiab welded thooj voos kheej kheej? **
* ** Ua daim ntaub tuab muag: ** Ua los ntawm ib daim ntawm cov khoom siv (zoo li cov hlua khi hlau) bored tawm los ua cov thoob. Qhov no tsim ib lub tog raj kheej uas tsis muaj kev sib tw ntev hauv cov ntaub ntawv tshaj lij thiab cov kev ntsuas siab dua. Lawv yog qhov tseem ceeb rau cov roj siab siab (zoo li scuba, kev kho mob oxygen, kev ua haujlwm tua hluav taws) lossis hydraulic qhov twg tsis muaj kev puas tsuaj.
* ** Welded thooj voos kheej kheej: ** Ua los ntawm dov ib lub tiaj tiaj mus rau hauv cov cylindrical thiab vuam lub longitudinal seam. Qhov xaus (lub taub hau tais) yog welded rau kaw lub tog raj kheej. Thaum muaj zog txaus rau ntau daim ntawv thov, cov Welds yog cov ntsiab lus ntawm tsis muaj zog piv rau kev tsim kho. Lawv muaj ntau yam rau cov ntawv thov txo qis-, tso tsheb hlau loj, lossis siv cua compressed uas tsim nyog tsim nyog.
4. ** Dab tsi yog Welded yeeb nkab? **
* Ib qho yeeb nkab welded yog ib hom steel yeeb tsim los ntawm kev tsim lub tiaj tus hlau phaj los yog cov duab tubular thiab tom qab ntawd siv cov qauv sib txuas ua ke tas mus li. Weld leeg khiav raws qhov ntev ntawm cov yeeb nkab (ntev ntev) lossis qee zaum ntawm koj. Cov Kev Siv Vuam xws li hluav taws xob tiv thaiv vuam (ERW), submerged arc vuam (EFW). Welded kav yog feem ntau yig tshaj li seamless kav thiab muaj nyob rau hauv lub diam loj dua.
5. ** Dab tsi yog cov kav dej seamless uas siv rau? **
* Seamless kav yog siv nyob rau hauv cov ntawv thov uas ntseeg tau nyob rau hauv kev ntxhov siab ntau yog qhov tseem ceeb thiab qhov twg lub peev xwm tsis muaj hwj chim yog qhov tsis tsim nyog. Cov siv sib xws li suav nrog:
* Kev muaj kev kub siab thiab siab-ntsuas kub hauv cov hlua hluav taws xob (boiler hlab, superheaters).
* Cov roj thiab kev tshawb nrhiav roj, ntau lawm, thiab kho kom huv (downhole tubing, casing, txheej txheem piping).
* Cov tshuab ntxhua khaub ncaws hydraulic thiab pneumatic.
* Tshuaj lom neeg thiab petrochemical ua cov nroj tsuag tuav corrosive lossis kua dej txaus ntshai.
* Cov kabmob thiab cov khoom siv tshuab hluav taws xob yuav tsum muaj cov kev siv zog holding hollow sections.
* Cov ntawv qhia tseem ceeb xav tau qhov tseem ceeb tshaj plaws.
