HSAWW PIPES (Muab kauv subderged arc welded yeeb nkab), yog mabe submered sib tw, muab cov yeeb nkab sab nraud. Raws li rau cov laj thawj hauv qab no, nws tau siv dav hauv kev tsim cov kab hlau loj hlau steel hlau:
1) Hloov cov duab sab, koj tuaj yeem siv tib lub strawb tib ntau lawm ntau cov yeeb nkab steel;
2) Vim tias nws yog khoov txuas ntxiv, qhov ntev ntawm steel yeeb nkab ntev yog txwv;
3) Weld Kauv-puab cov kev faib tawm ntawm cov yeeb nkab ntawm tag nrho cov yeeb nkab steel, steel yeeb nkab loj, siab ntsuas, muaj kev siv siab;
4) Yooj yim hloov qhov loj me rau cov yeeb nkab me me ntawm cov yeeb nkab ntau lawm ntawm ntau ntau yam.
Muab Kauv Weld Seam Ncaj Ncaj Ntev, Tube ntev L L, Weld ntev yog L / COS (8). Rau lub sijhawm ntev sib cav sib haum xeeb thiab ncaj qhaub yeeb, tshwj xeeb, uas yog qhov zoo tshaj plaws piv nrog UoE steel yeeb nkab. Muab cov kauv yeeb nkab raug tshuab rau niaj hnub no, peb yuav tsum tshuaj ntsuam xyuas dav thiab raug thiab kev sib piv thiab kev sib piv, lub tswv yim ntawm ?? muaj kauv ntev kauv weld.
Ua ntej tshaj plaws, vim tias qhov tsis xws luag hauv Weld Parallel, rau cov kauv yeeb nkab, rau cov kauv yeeb nkab, lub weld tsis zoo yog li "oblique tsis xws luag". Thaum siv, tus thawj tswj kev ntxhov siab ntawm cov yeeb nkab steel, cov yeeb nkab axis kev taw qhia ntev yog samll dua li txoj kab ncaj ncaj yog me me; Thib ob, txij li cov raj xa dej yog dov phaj, cuam tshuam kev sib txawv loj anisotropy raws cov rooj kev taw qhia ntau dua li cov kab xev ntawm CVN muaj nqis peb zaug siab dua. Txoj kev ntxhov siab ncaj ncaj los ntawm cov kev ntxhov siab tseem ceeb yog ua kom cov yeeb nkab qis tshaj plaws ntawm cov yeeb nkab tsis kam, yog li ntawd cov kauv weld tsis zoo rau hauv cov txiaj ntsig.
