ST52/45#/Q345/16Mn paipu kila ʻole

Hoʻoponopono Kūmole:

Hana ʻia nā paipu kila maʻemaʻe me ke kila poepoe holoʻokoʻa. ʻO nā paipu kila me nā wili ʻole ma ka ʻili i kapa ʻia he paipu kila ʻole. E like me keʻano hana, hiki ke maheleia nā paipu kila maʻemaʻe i loko o nā paipu kila hoʻoheheʻeʻia, nā paipu kila maʻamau i'ōwiliʻia, nā paipu kila maʻamau, nā paipu kila kila extruded, nā paipu jacked, a me nā mea'ē aʻe. shape, seamless kila paipu ua maheleia i elua ano: poepoe a me ka kūikawā-like. He ʻano paʻakikī like ʻole nā ​​paipu koʻikoʻi e like me ka huinaha, oval, triangle, hexagon, melon-like, star-like, a me nā paipu finned. ʻO 900mm ka palena kiʻekiʻe a ʻo ka palena iki he 4mm. E like me nā hoʻohana ʻokoʻa, aia nā paipu kila maʻemaʻe ʻole o ka paia a me nā paipu kila ʻeleʻele. Hoʻohana nui ʻia nā paipu kila maʻemaʻe e like me nā paipu hoʻoheheʻe ʻana i ka aila, nā paipu haki no ka ʻoihana petrochemical, nā paipu paila, nā paipu halihali, a me nā paipu kila kila kiʻekiʻe no nā kaʻa, tractors, a me nā mokulele.

ʻO ka paipu kila Q345, ʻike ʻia hoʻi ʻo 16Mn, 16Mn seamless steel pipe he mea hao hao haʻahaʻa maʻamau. He kila maʻamau ia no nā paila a me nā ipu kaomi. ʻO ka'ōwili wela a maʻamau paha. He kila haʻahaʻa haʻahaʻa me ka haʻahaʻa Mn maʻiʻo. Ua like ka hana me 20G (412-540), ʻoi aku ka ikaika o ka tensile (450-655), a ʻo 19-21% ka elongation, ʻoi aku ka maikaʻi ma mua o 20G i ʻoi aku ma mua o 24%.

ʻO ka 16Mn seamless steel pipe he pā kūikawā no nā moku kaomi me ka ikaika o ka 340MPa. Loaʻa iā ia nā waiwai mechanical piha maikaʻi a me ka hana kaʻina hana. ʻOi aku ka haʻahaʻa o ka phosphorus a me ka sulfur ma mua o ke kila 16Mn maʻamau. Ma kahi o ka ikaika tensile a me nā koi elongation e ʻoi aku ka kiʻekiʻe ma mua o ke kila 16Mn maʻamau, pono e hōʻoia ʻia ka paʻakikī o ka hopena. ʻO ia ka mea hoʻohana nui a hoʻohana nui ʻia i ka pā kila kūikawā no nā puka makani kaomi i koʻu ʻāina.

45 # kila: ka awelika kalapona maʻiʻo he 0.42-0.50%, awelika silikona maʻiʻo he 0.17-0.37%, awelika manganese maʻiʻo he 0.50-0.80%, awelika sulfur maʻiʻo <=0.035%, awelika phosphorus maʻiʻo <=0.035% , awelika chromium maʻiʻo. <=0.25%, maʻiʻo nickel maʻamau <=0.2545 kila

Description:

Hana ʻia nā paipu laulima ʻole mai nā bilets kila poepoe i kuʻi ʻia ma ke kikowaena e hana i nā paipu hollow i ʻōwili ʻia a i waho a huki ʻia i ka nui.

hoakaka:

Papa kuhikuhi paipu ʻole

noi:

He kūpono no ka ʻaila, aerospace, mana uila, boiler, kemika a me nā ʻoihana ʻē aʻe.

'Apono kūpono:

Loaʻa i kā mākou hale hana nā lako hana a me ka ʻenehana, hiki ke hana i nā paipu kila maʻemaʻe o nā ʻano kikoʻī a me nā hiʻohiʻona. Hoʻopaʻa ʻia ka maikaʻi o ka huahana, ʻoluʻolu nā ala kūʻai aku, a he 7 * 24 mau hola ma hope o ke kūʻai aku e hōʻoia i ka lawelawe ma hope o ke kūʻai aku.
