GB8163 Line Steel Pipe Seamless Steel Pipe

ʻO ka wehewehe pōkole:

Hoʻohana ʻia ʻo GB 8163 Seamless Steel Pipe no ka lawe ʻana i ka aila, ke kinoea maoli a me nā wai maʻamau.ʻO ka paipu kila he ʻāpana hakahaka, a hoʻohana nui ʻia ma ke ʻano he paipu no ka lawe ʻana i ka wai, e like me ka aila, ke kinoea maoli, ke kinoea, ka wai a me kekahi mau mea paʻa.

Ke hoʻohālikelike ʻia me ke kila paʻa e like me ke kila poepoe, he māmā ke kaumaha o ka paipu kila ke like ka ikaika o ka piko a me ka torsion.He kila ʻāpana ʻāpana waiwai a hoʻohana nui ʻia no ka hana ʻana i nā ʻāpana hana a me nā ʻāpana mechanical, e like me ka paipu ʻaila ʻaila, kaʻa hoʻoili kaʻa, ka pahu kaʻa a me ka scaffold kila i hoʻohana ʻia i ke kūkulu ʻana.Hiki i ka hana ʻana i nā ʻāpana apo me nā paipu kila ke hoʻomaikaʻi i ka hoʻohana ʻana o nā mea waiwai, hoʻomaʻamaʻa i ke kaʻina hana, a mālama i nā mea hana a me nā hola hana, e like me nā apo wili a me nā lima lima Jack.I kēia manawa, hoʻohana nui ʻia nā paipu kila no ka hana ʻana.ʻO ka paipu kila kekahi mea pono no nā ʻano mea kaua maʻamau.ʻO ka pahu a me ka pahu o nā pū he paipu kila.Hiki ke hoʻokaʻawale ʻia nā paipu kila i nā paipu poepoe a me nā paipu ʻano kūikawā e like me nā ʻāpana cross-sectional a me nā ʻano like ʻole.No ka mea, ʻo ka ʻāpana pōʻai ka nui loa ma lalo o ke ʻano o ke anapuni like, hiki ke lawe ʻia ka wai e nā paipu pōʻai.Eia kekahi, i ka wā e hoʻokau ʻia ai ka ʻāpana apo i ke kaomi radial i loko a i waho paha, ʻoi aku ka like o ka ikaika.No laila, ʻo ka hapa nui o nā paipu kila he paipu poepoe.

Kūlana: GB/T8163.

Main Steel Tube Grade: 10, 20, Q345, etc.

Hiki ke hāʻawi ʻia nā māka ʻē aʻe ma hope o ke kūkākūkā ʻana me nā mea kūʻai aku.

Kaʻina Hana ʻenehana

ʻO ka ʻōwili wela (ka hoʻokuʻu ʻana i ka paipu kila maʻemaʻe): ʻo ka pahu pōʻai pōʻai → ka hoʻomehana → ke kuʻi ʻana → ʻekolu ʻōwili keʻa kaʻa, ka ʻōwili mau ʻana a i ʻole ka extrusion → ka wehe ʻana o ka paipu → ka hoʻonui ʻana (a i ʻole ka hōʻemi ʻana) → ka hoʻoluʻu → ka paipu blank → hoʻopololei → ka hoʻāʻo hydrostatic (a i ʻole ka ʻike kīnā) → hōʻailona → hale kūʻai.

ʻO ka paipu kila ʻaʻole i huki ʻia (ʻōwili ʻia) maʻemaʻe: puʻupuʻu pōʻai billet → hoʻomehana → perforation → poʻomanaʻo → annealing → pickling → ka uhi ʻaila (pale keleawe) → kaha kiʻi anuanu (cold rolling) → billet → mālama wela → straightening → hydrostatic test (flaw ʻike) → hōʻailona → hale kūʻai.
