Mulu wa Mapaipi a JIS A5525 SKK490 SSAW: Mphamvu Zopangira & Mafotokozedwe a Zogulitsa

Kufotokozera Kwachidule:

Womic Steel imapereka mulu wa mapaipi achitsulo a JIS A5525 SKK490 SSAW apamwamba kwambiri ogwiritsira ntchito nyumba zapamadzi ndi zapamadzi m'misika ya ku Asia. SKK490 imapereka mphamvu yocheperako ya 325 MPa (47,100 psi) ndi mphamvu yocheperako ya 490 MPa (71,100 psi). Mulu wa mapaipi olumikizidwa ndi arc wozungulira ndi wabwino kwambiri pomanga madoko, kuyika madoko, maziko a breakwater, ndi uinjiniya wa maziko akuya. M'mimba mwake wakunja kuyambira 508mm mpaka 3000mm, makulidwe a khoma kuyambira 6.0mm mpaka 25.4mm, kutalika mpaka 60m. Satifiketi ya mphero, mayeso a hydro, mayeso a ultrasonic, malekezero opindika okhala ndi mphete zachitsulo zodzipereka, chophimba choteteza dzimbiri chilipo. Mtengo wopikisana komanso kutumiza mwachangu.

Kukula kwa Mulu wa Chitoliro cha SSAW:M'mimba mwake wakunja: 508mm-3000mm, Kukhuthala kwa khoma: 6.0mm-25.4mm, Kutalika: 6m-60m ngati pakufunika

Mulingo Wabwino ndi Woyenera wa Mulu wa Mapaipi a SSAW:JIS A5525 SKK400, SKK490, SKK540; JIS G3444 STK290, STK400, STK490, STK540; ASTM A252 GR.3; EN 10248 S355GP

Kugwiritsa Ntchito Mulu wa Mapaipi a SSAW:Kumanga madoko, kumanga madoko, maziko a makoma a madzi, kumanga madoko ndi madoko, maziko a mlatho, chitetezo cha m'mphepete mwa nyanja, uinjiniya wa maziko ozama, kukonzanso malo

Chitsulo cha Womickupereka mitengo yapamwamba komanso yopikisana ya JIS A5525 SKK490 SSAW chitsulo cha mapaipi, spiral welded piling payipi, Japan standard payipi pile. Chiphaso cha mphero, hydro test, UT, beveled end yokhala ndi mphete zachitsulo, 3PE/FBE coating ikupezeka. Kupereka mwachindunji kwa mafakitale kwa mapulojekiti aukadaulo wapamadzi aku Asia.
