JIS A5525 SKK490 SSAW Umuyoboro w'imiyoboro: Ubushobozi bwo gukora n'ibisobanuro by'ibicuruzwa

Ibisobanuro bigufi:

Womic Steel itanga umuyoboro w'icyuma wa JIS A5525 SKK490 SSAW mwiza cyane wo kubyambu no ku nyubako zo mu mazi mu masoko yo muri Aziya. SKK490 itanga imbaraga nkeya za 325 MPa (47.100 psi) n'imbaraga nkeya za 490 MPa (71.100 psi). Umuyoboro w'icyuma ukozwe mu buryo bwa spiral ukozwe mu buryo bwa arc ni mwiza cyane mu kubaka icyambu, gupakira ikiraro, ishingiro ry'amazi, no gukora urufatiro rwimbitse. Ingano y'umurambararo wo hanze kuva kuri 508mm kugeza 3000mm, ubugari bw'urukuta kuva kuri 6.0mm kugeza 25.4mm, uburebure kugeza kuri 60m. Icyemezo cy'uruganda, ikizamini cy'amazi, ikizamini cya ultrasonic, impeta y'icyuma ifite impeta z'icyuma, irahari. Igiciro cyiza kandi gitangwa vuba.

Ingano y'umuyoboro wa SSAW:Ingano yo hanze: 508mm-3000mm, Ubunini bw'urukuta: 6.0mm-25.4mm, Uburebure: 6m-60m uko bikenewe

Igipimo n'Ingano by'Umuyoboro wa SSAW:JIS A5525 SKK400, SKK490, SKK540; JIS G3444 STK290, STK400, STK490, STK540; ASTM A252 GR.3; EN 10248 S355GP

Imikoreshereze y'Umuyoboro wa SSAW:Gushinga imigozi y'icyambu, kubaka icyambu, ishingiro ry'amazi, gushinga imigozi y'icyambu n'icyambu, ishingiro ry'ibiraro, kurinda inkombe, ubwubatsi bw'imigozi miremire, gutunganya ubutaka

Womic SteelItanga ibiciro byiza kandi bishimishije by'umuyoboro w'icyuma wa JIS A5525 SKK490 SSAW, umuyoboro wometseho uruziga, umuyoboro usanzwe w'Abayapani. Icyemezo cy'uruganda, ikizamini cy'amazi, UT, impera ifite impeta z'icyuma, irangi rya 3PE/FBE rirahari. Itangwa ry'ibikoresho mu ruganda ku mishinga y'ubuhanga mu by'amazi yo muri Aziya.

Ohereza imeri kuri twe Ibisobanuro by'ibicuruzwa

Ibisobanuro birambuye ku gicuruzwa

Ibirango by'ibicuruzwa

1. Womic Steel: Ubushobozi bwo gukora n'imbaraga z'ikigo

Womic Steel Group ni uruganda rukomeye rukora ibintu bitandukanye kandi rutumiza mu mahanga ku isi rufite ubunararibonye bw'imyaka irenga 20 mu gukora ibikoresho bya karuboni, alloy, na stainless steel tubular. Urwego rwacu rugezweho rwo gukora imiyoboro ya SSAW rufite ubushobozi bwo gukora toni zigera ku 15.000 buri kwezi ku miyoboro y'ibyuma ikoreshwa mu byuma bicukurwa mu mazi, bigafasha mu mishinga yo mu mazi y'Abayapani n'Aziya.
