ʻO ka wela wili no ka ʻōwili wela
Hiki i ka hoʻololi ʻana i ka wela ke hoʻololi i ka nui o ka palaoa i ʻōwili ʻia i ke kila recrystallization, ka nui o ka deposition a me nā loli morphology, e hoʻololi ai i nā waiwai mechanical.Pono e hoʻopau i ka wela o ka ʻōwili ʻana, e hoʻokiʻekiʻe i ka wela o ka wili, e hoʻonui i ka nui o nā kīʻaha recrystallized, ka m...Heluhelu hou aku -
Pono o Submerged Arc Welding Spiral Steel Pipe
I ke kaʻina hana paipu spiral a me ka hoʻohana ʻana, ua hana ʻia ka nui o nā kuʻihao maikaʻi loa a me nā ʻano hana o ka hana ʻana, kōkua nui i ka hoʻomohala mau a me ka wikiwiki o ka ʻoihana, akā ua hoʻomaikaʻi ʻia kēia ʻoihana i ka hoʻomohala ʻana.ʻO ka welding arc submerged he wel...Heluhelu hou aku -
ʻO ka paipu hāʻawi kiʻekiʻe kiʻekiʻe i hui pū ʻia
ʻO ka paipu hāʻawi kiʻekiʻe kiʻekiʻe o ka composite ka mea i hana ʻia me ka polymer me kahi ikaika kiʻekiʻe, kiʻekiʻe kiʻekiʻe, corrosion, fouling resistance, friction coefficient, insulation maikaʻi, hoʻololi maikaʻi a me ke ola lōʻihi o kahi paipu ʻenehana ʻaila.Hiki ke hoʻohuihui kiʻekiʻe-...Heluhelu hou aku -
ʻO nā hiʻohiʻona o ke kūʻē ʻana i nā paipu kila uʻi (ERW steel pipe)
ʻO ERW (Electric Resistance Welding) paipu kila i kapa ʻia ʻo ERW paipu a i ʻole HF welded paipu, he nui nā mea maikaʻi e like me kēia: 1) kiʻekiʻe o ka hana ʻana, haʻahaʻa kumu kūʻai, ʻo kona kumukūʻai e pili ana i ka UOE straight seam submerged arc welded steel, 85 %;2) kiʻekiʻe dimensional pololei, kona poepoe (Round...Heluhelu hou aku -
ʻO ke kaʻina hana paipu kila ʻole carbon
Pehea e hana ʻia ai ka paipu kila ʻole?Hana ʻia nā paipu kila maʻemaʻe ma ka hoʻomehana ʻana i ka ingot paʻa a me ka hoʻokuʻu ʻana i ke koʻokoʻo e hana i kahi paipu puha.Hiki ke hana ʻia ka hoʻopau ʻana i ke kila maʻemaʻe ma o nā ʻenehana e like me ka ʻōwili wela, huki ʻia ke anu, hoʻohuli ʻia, loko-rolled etc. Ma hope o ka hele ʻana i ka pau ʻana ...Heluhelu hou aku -
ʻO ka mīkini hoʻoneʻe ʻana i ka hale paʻa
Hoʻonohonoho o ka haʻahaʻa-carbon kila ma ka lumi wela deformation o ferrite a me ka pearlite, ina aia ka hui hui o ferrite a me ka pearlite alternating paʻi.Haʻahaʻa kalapona kila seamless paipu hui pū, mai ka lumi wela a hiki i ka normalizing mahana, i ka ma o Ac1 temp...Heluhelu hou aku
