1. Cov kev kho deg rau seamless carbon steel kav yog dab tsi?
Kev kho saum npoo:
* Dub casing (thawj nto): xeb- tiv thaiv roj
* Painting: xim liab, xim daj, xim xiav, zinc- nplua nuj xim
* hmoov txheej, tiv thaiv- txheej txheej
* Threading, beveling, flange vuam pretreatment
* Export feem ntau siv xeb-cov roj tiv thaiv + woven hnab / ntoo crates rau ntim.
2. Yuav ua li cas txiav txim qhov zoo ntawm seamless carbon steel kav?
Cov ntsiab lus tseem ceeb rau kev txiav txim:
* Txawm tias cov khoom ua tau raws li cov qauv, muab cov ntaub ntawv pov thawj, tshuaj muaj pes tsawg leeg, thiab cov khoom siv tshuab
* Txawm tias muaj cov kab nrib pleb, folds, nti, lossis qhov pits ntawm sab hauv thiab sab nrauv
* Seb phab ntsa thickness yog uniform thiab ovality yog tsim nyog
* Seb qhov kev ntsuam xyuas hydrostatic thiab tsis yog -kev kuaj kev puas tsuaj puas tsim nyog
* Txawm hais tias qhov tseeb qhov tseeb, qhov ntev, beveling, thiab chamfering ua tau raws li qhov yuav tsum tau ua
* Cov tuam txhab muaj npe nrov tuaj yeem muab cov ntawv xeem ua tiav rau txhua pawg.
3. Puas seamless carbon steel kav yuav tsum tau mus kuaj hydrostatic?
Yog lawm. Tag nrho cov kav dej seamless siv rau cov kua dej, boilers, thiab pipelines yuav tsum tau mus kuaj hydrostatic. Cov kav dej yog pressurized rau tus qauv siab rau ib lub sij hawm ntawm lub sij hawm; tsis muaj dej los yog deformation qhia tau hais tias tsim nyog. Peb ua 100% hydrostatic kuaj ua ntej ua zaub mov xa tuaj kom muaj kev nyab xeeb siv.
4. Puas yog seamless carbon steel yeeb nkab tsis muaj -kev kuaj kev puas tsuaj (UT/RT)?
Raws li cov neeg siv khoom thiab cov qauv, peb tuaj yeem muab:
UT Kev Ntsuas Ultrasonic
MT Magnetic Particle Test
ET Eddy Current Testing
Siv los txheeb xyuas qhov tsis xws luag sab hauv, tawg nto, thiab vuam tsis xws luag (cov kav dej seamless feem ntau sim rau qhov tsis xws luag sab hauv), ua kom muaj kev nyab xeeb siv nyob rau hauv siab -siab thiab siab - ib puag ncig txaus ntshai.
5. Qhov txawv ntawm 20# steel thiab Q355B yog dab tsi? Yuav xaiv li cas?
20#: High-cov pa roj carbon zoo, zoo plasticity thiab toughness, yooj yim rau vuam, haum rau kev thauj mus los ntawm cov dej thiab nruab nrab - mus rau - cov kav dej tsis tshua muaj siab.
Q355B: Tsawg- alloy siab- lub zog steel, siab zog thiab zoo dua load- bearing muaj peev xwm, haum rau cov qauv, tshuab, kev txhawb nqa, thiab engineering machinery.
Xaiv raws li daim ntawv thov: Xaiv 20 # rau kev thauj mus los, xaiv Q355B rau cov qauv siv.
