Isingeniso sokusebenza kwe-S355j0w

1. Ukwethulwa okufushane kwepuleti yensimbi ye-S355j0w:

I-S355J0W iyinsimbi evamile ye-Europe Everalrospheric-arrantic yokulwa ne-europe, okungokwepuleti yensimbi engazweli kahle yesimo sezulu. Kuyinsimbi ephansi ye-alloy eyenziwe ngokungeza inani elithile lezinto ze-alloy kwinsimbi ejwayelekile. Ukumelana nokonakala komkhathi kwensimbi yesimo sezulu kuyizikhathi ezi-2-8 zensimbi evamile yekhabhoni, futhi inezakhiwo ezinhle zemishini, izakhiwo ze-welding, njll.

2. I-S355J0W ithuthukiswe ngensimbi yokuphikisana nomyeni

Inani elithile lezinto ezenziwa nge-alloying lingezwa kwinsimbi, njenge-P, Cu, Cr, NI, MO, ukuze sikhulise ukumelana nokugqwala komoya, futhi ngaphansi kwethonya lezimo zezulu, kuzovunyelwa i-othomathitha othomathikhi I-Base Metal.

3. Isimo sokulethwa kwe-S355J0W:

Ilethwe esimweni esishisayo esishisayo, esijwayelekile noma esijwayelekile.

Izinga elisezingeni eliphakeme lensimbi yesine, s355j0w

I-S355j0J0W itments En10025-5: Izinga le-2004.

I-5. I-S355J0W ithuthukiswe ngensimbi yokumelana nomoya

Inani elithile lezinto ezenziwa nge-alloying lingezwa kwinsimbi, njenge-P, Cu, Cr, NI, MO, ukuze sikhulise ukumelana nokugqwala komoya, futhi ngaphansi kwethonya lezimo zezulu, kuzovunyelwa i-othomathitha othomathikhi I-Base Metal.

6. Umthamo wethu wokuhlinzekelwa:

1. Ububanzi be-spate yensimbi etholakalayo: ubukhulu be-8-700mm, ububanzi obungu-1500- 4020mm, ubude 4000mm-17000mm-17000mm-17000mm-17000mm-17000mm, Isisindo seyunithi sifinyelela kumathani angama-30,00. Amapuleti amakhulu ensimbi amabanga ayatholakala ngesicelo.

2. Izinhlobo zamapuleti ensimbi atholakalayo: amapuleti ensimbi ehlelekile e-carbon, amapuleti ensimbi aphansi aphezulu, amapuleti ensimbi epulatifomu elokwakha amapulatifomu, amapuleti ensimbi ama-boilers kanye nemithambo yengcindezi, insimbi amapuleti okubumba, amapuleti ensimbi enhlambo ye-alloy, kunezigaba eziyi-12 zamapuleti ensimbi wamapuleti kawoyela namagesi, amapuleti ensimbi agxile kakhulu, namapuleti ensimbi avimbela izinsimbi, kanye namapuleti angaphezu kwama-300 asekhaya kanye imikhiqizo yakwamanye amazwe.

I-3. Iyatholakala ngezidingo zokuthola iphutha, ama-z15-z35 ukuqina kokuqondisa ukuqondiswa kwezidingo, amandla aphezulu kanye nezidingo eziphakeme ezinobunzima namanye amapuleti ensimbi.

I-4. Ingahlinzekwa ngokuya ngamazinga kazwelonke, amazinga we-metallurgical, amazinga aseMelika aisi / ASME / ASTM, isiJalimane Standard Din, i-French NF, i-European En, i-International Iso namanye amazinga.
