Lub Ceiling Loj Tsis muaj leej twg hais txog thaum koj ntaus nws
Seamless hollow seem muaj ib qho kev txwv nyuaj uas welded hollow seem tsis yog: nws yog tsim los ntawm tho thiab elongating ib tug puag ncig billet, ces kub - ua rau seamless raj rau hauv nws cov duab zaum kawg. Cov txheej txheem tho lub kaus mom tawm ntawm txoj kab uas hla - feem ntau cov mills tsis tuaj yeem khiav seamless niam raj ntau dhau los ntawm kwv yees li 400-450 mm OD ua ntej cov txheej txheem tho yuav tsis ntseeg lossis tsis muaj nqis. Saum toj no, txhua seem hollow ntawm kev ua lag luam, seamless los yog tsis, yog welded.
Qhov no tseem ceeb ntawm qhov kev yuav khoom vim tias nws yog ib qho kev tsis sib haum xeeb: ib tug neeg qhia tias "seamless" tawm ntawm tus cwj pwm los yog kev nkag siab dav dav tias nws yog qhov kev xaiv hwm, yam tsis tau kuaj xyuas seb lawv qhov loj npaum li cas txawm tias muaj seamless. Yog hais tias koj qhov project xav tau ib yam dab tsi saum toj no roughly 400 mm CHS los yog ib tug square / rectangular seem nrog cov bounding qhov ntev, seamless tsis nyob rau hauv lub rooj - spec yuav tsum tau tsiv mus rau welded (TS EN 10219txias-ua los yog kub- tiav welded) txawm tias nyiam.
Thaum Seamless Tiag Tau Txais Nws Tus Nqi
Seamless nqi ntau dua welded hollow seem ntawm tib qhov loj thiab qib - feem ntau 20-40% ntau nyob ntawm qhov loj thiab kev lag luam. Tus nqi ntawd tsim nyog them rau qee qhov xwm txheej, thiab tsis tsim nyog them rau lwm tus:
Tsim nyog:
- Siab -siab lossis qaug zog- kev pabcuam caij tsheb kauj vab- hydraulic thooj voos kheej kheej, cov hlab ntsha siab, thiab cov kav dej ua rau muaj kev rov ua kom lub zog rov ua haujlwm tau txais txiaj ntsig los ntawm kev tsis muaj seam los ua qhov chaw muaj kev ntxhov siab lossis tshuaj xyuas qhov chaw tsis muaj zog.
- Heav machining tom qab xa khoom- yog hais tias seem yuav dhuav, threaded, los yog machined heev, ib tug weld seam yuav coj txawv dua li cov niam txiv hlau nyob rau hauv cov cuab yeej txiav, tsim inconsistent nto tag los yog cov cuab yeej hnav. Seamless zam qhov sib txawv kiag li.
- Kev sib txuas ntawm cov qauv tseem ceeb nrog tag nrho - seem kev xav tau- qee tus qauv tsim qauv muab qhov sib txawv me ntsis (ntau dua kev saib xyuas) muaj peev xwm rau welded hollow seem ntawm qhov chaw seam; seamless sidesteps uas de- ntsuas.
- Offshore, subsea, lossis qaub- qhov chaw pabcuam- qhov twg seam corrosion los yog seam -txog NDT tsis ua hauj lwm muaj qhov tshwm sim loj heev, seamless feem ntau raug yuam los ntawm qhov project spec tsis hais tus nqi.
Tsis tsim nyog:
- General tsev framing(kem, kab teeb, bracing) - EN 10219 welded hollow seem yog tsim thiab sim nqa cov loads nrog lub qhov dej-tsim seam-cov ntaub ntawv zoo; them tus nqi seamless ntawm no yog tsis tshua muaj kev ncaj ncees los ntawm tus qauv engineers qhov kev xav tau tiag tiag.
- Zoo li qub, qis - daim ntawv thov mus ncig- fencing, handrail, low -pressure conveyance - qhov twg weld seam qhia tsis muaj txiaj ntsig txaus ntshai.
- Loj loj saum lub qab nthab seamless- saib saum toj no; qhov kev xaiv tsis muaj nyob, yog li tsis muaj nqi / tsis muaj- qhov kev txiav txim siab zoo.
Cov lus nug nquag nug (FAQ)
Q: Vim li cas seamless square raj muaj lub kaum sab xis loj dua welded square raj?
A: Vim nws yog kub- tsim los ntawm puag ncig seamless raj es tsis txias - dov los ntawm lub tiaj tiaj tiaj tiaj, thiab kub- ua ib ntu tuab rau hauv cov duab square tsis compress lub ces kaum kom nruj li strip yob - sib sau ua.
Q: Kuv puas xav tau seamless hollow seem rau lub tsev tsim qhov project?
A: Feem ntau tsis yog. Standard tsev framing framing yog tsim nyob ib ncig ntawm welded hollow seem (EN 10219), uas yog sim thiab code- ntsuas rau cov qauv siv. Seamless feem ntau yog tshwj tseg rau siab, qaug zog-tseem ceeb, lossis siv cov tshuab ua haujlwm hnyav ntau dua li cov txheej txheem dav dav.
Q: Qhov "H" hauv qib zoo li S355J2H txhais li cas?
A: H suffix txhais tau hais tias qhov kev xaiv qib siv tshwj xeeb rau cov seem hollow (xws li cov phaj lossis cov seem qhib), raws li EN 10210's qib naming convention - nws tsis qhia txog kev sib txawv ntawm chemistry los ntawm lub hauv paus S355J2 kev xaiv.
Q: EN 10210 seamless hollow seem puas tuaj yeem kub -dip galvanized?
A: Yog, nrog kev ceev faj tib yam li ib qho hollow seem - welded box seem (hauv qhov no, tsuas yog cuam tshuam yog tias ntxiv fabricated nrog kaw welds) xav tau qhov vent qhov rau galvanizing; Plain seamless raj seem galvanize yam tsis muaj qhov kev txhawj xeeb vim tias lawv tsis muaj kab noj hniav hauv welds rau ntxiab roj.
