1. ** Dab tsi yog lsaw yeeb nkab? **
Lub lsaw yeeb nkab (longitudinal submerged arc welded yeeb nkab) yog ib hom steel daim hlau tsim los ntawm cov stires siv cov submerged arc vuam (pom) txheej txheem. Nws yog ib qho siv rau cov ntawv thov siab, xws li roj thiab roj kis, vim nws lub zog siab thiab kev ntseeg tau.
2. ** Dab tsi yog qhov txawv ntawm Erd thiab lsaw yeeb nkab? **
- ** ERW (hluav taws xob tiv thaiv welded) yeeb nkab ** yog ua los ntawm dov hlau coils thiab vuam lub leeg uas siv hluav taws xob siv hluav taws xob, ua kom huv. Nws yog feem ntau siv rau tsawg rau nruab nrab cov ntawv thov.
- ** LSAWW cov yeeb nkab ** yog tsim los ntawm cov hlau nplaum, welded longitudinally siv submerged arc vuam, thiab yog haum rau kev siv siab thiab loj-ntawm cov kev siv uas siab. LSAWaw kav feem ntau muaj zog dua thiab ua tau zoo hauv kev xav tau ib puag ncig piv rau ERW kav.
3. ** LSAWW sawv? **
LSAW Stood rau ** Longitudinal submerged arc welded **, hais txog kev tsim khoom ua rau cov phiaj txheem hlau yog welded longitudinally siv cov submerged arc vuam txheej txheem.
4. ** Dab tsi yog qhov sib txawv ntawm hsaw thiab lsaw? **
- ** LSAWW (Longitudinal submerged arc welded) ** kav yog welded raws qhov ntev (ntev ntev) thiab feem ntau yog siv rau cov kav dej loj.
- ** HSAW (helical submerged arc welded) ** Tseem paub tias ssaw (kauv subdergle (kauv subdergle welded), yog tsim los ntawm spirally winding hlau chee thiab vuam lawv nyob rau hauv ib tug helical leeg. HSAWW Pipes hloov tau yooj yim dua hauv txoj kab uas hla tab sis tej zaum yuav muaj qhov qis dua me ntsis piv rau lsaw kav.
5. ** Dab tsi yog hsaw yeeb nkab? **
Cov yeeb nkab hsaw (helical submerged arc Welded yeeb nkab) yog hom hlau yeeb nkab tsim los ntawm kev sib tw sib xyaw ua ke los ntawm kev siv cov leeg ntoo lossis vuam siv submerged arc vuam. Nws feem ntau siv hauv dej kis, piling, thiab cov ntawv thov uas muaj qhov ntsuas siab tiv thaiv siab yuav tsum muaj.
