Paipu kila hoʻohiwahiwa kila
Ua kapa ʻia ka paipu hoʻohiwahiwa kuhili ʻole, ka mea i kapa ʻia ʻo welded pipe no ka pōkole.ʻO ka maʻamau, hoʻopaʻa ʻia ke kila a i ʻole ke kaula kila i loko o ka paipu kila ma hope o ka crimped a hoʻokumu ʻia e ka ʻāpana a me ka mold.He maʻalahi ke kaʻina hana o ka paipu kila welded, ʻoi aku ka maikaʻi o ka hana ʻana, he nui nā ʻano a me nā kikoʻī, a liʻiliʻi ke kumukūʻai o nā mea hana, akā ʻoi aku ka haʻahaʻa o ka ikaika ma mua o ka paipu kila seamless.
Nui nā ʻano paipu kila kila, akā hoʻohana nui ʻia lākou no nā kumu penei:
1、Hoʻokaʻawale ʻana i nā paipu kila kila
1. Hoʻokaʻawale ʻia ma ke ʻano hana:
(1) Paipu ʻole – paipu huki anu, paipu hoʻokuʻu ʻia, paipu ʻōwili anu.
(2) Paipu huila:
(a) E like me ke kaʻina hoʻokaʻawale - kinoea pale kuʻihao paipu, arc kuʻihao paipu, kū'ē kuʻihao paipu (frequency kiʻekiʻe, low frequency).
(b) Ua mahele ia i ka paipu wili pololei a me ka paipu wiliwili spiral e like me ka weld.
2. Hoʻokaʻawale ʻia e like me ke ʻano o ka ʻāpana: (1) paipu kila puni;(2) Paipu huinahāhā.
3. Hoʻokaʻawale ʻia e ka mānoanoa o ka pā - paipu kila pā lahilahi, paipu kila pā mānoanoa
4. Hoʻokaʻawale ʻia ma o ka hoʻohana ʻana: (1) Ua māhele ʻia nā paipu kīwila i nā paipu poepoe, nā paipu rectangular a me nā paipu pua, i hoʻohana mau ʻia no ka hoʻonaninani, ke kūkulu ʻana, ka hale, a pēlā aku;
(2) Paipu ʻoihana: paipu kila no ka paipu ʻoihana, paipu kila no ka paipu maʻamau (paipu wai inu), ka hoʻolālā mechanical/paipu hāʻawi wai, paipu hoʻololi wela o ka paila, paipu hoʻomaʻemaʻe meaʻai, a me nā mea ʻē aʻe. , e like me ka petrochemical, ka pepa, ka ikehu nuklea, ka meaʻai, ka mea inu, ka lāʻau lapaʻau a me nā ʻoihana ʻē aʻe me nā koi kiʻekiʻe no ka ʻenehana wai.
2、Paipu kila ʻole
He ʻano kila lōʻihi me ka ʻāpana ʻūhā a ʻaʻohe ami a puni.
1. Ke kaʻina hana a me ke kahe ʻana o ka paipu kila ʻole:
ʻO ka hoʻoheheʻe ʻana>ingot> ka ʻōwili kila> ka ʻili ʻana> ka ʻili ʻana> ka hoʻopiʻi ʻana> annealing> pickling> ka hoʻouka ʻana i ka lehu> ke kiʻi anuanu> ʻoki poʻo> pickling> warehousing.
2. Nā hiʻohiʻona o ka paipu kila ʻole:
ʻAʻole paʻakikī ke ʻike mai ke kaʻina hana i luna: ʻo ka mea mua, ʻoi aku ka mānoanoa o ka pā o ka huahana, ʻoi aku ka ʻoihana a me ka hana.ʻOi aku ka lahilahi o ka mānoanoa o ka pā, ʻoi aku ka kiʻekiʻe o ke kumukūʻai hana;ʻO ka lua, ʻo ke kaʻina hana o ka huahana e hoʻoholo i kona mau palena.ʻO ka mea maʻamau, he haʻahaʻa ka pololei o ka paipu kila liʻiliʻi: ʻaʻohe mānoanoa o ka paia, haʻahaʻa haʻahaʻa o ka ʻili i loko a i waho o ka paipu, ke kumukūʻai kiʻekiʻe, a aia nā lua a me nā wahi ʻeleʻele ma ka ʻili i loko a i waho o ka paipu, he paʻakikī ke hoʻopaʻa. wehe;ʻO ke kolu, pono e hoʻopaʻa ʻia kona ʻike ʻana a me kona hoʻohua ʻana.No laila, loaʻa iā ia nā mea maikaʻi i ke kaomi kiʻekiʻe, ka ikaika kiʻekiʻe a me nā mea hana mechanical.
3、Paipu kila welo

2. Nā hiʻohiʻona o ka paipu kila welded:
ʻAʻole paʻakikī ke ʻike mai ke kaʻina hana i luna: ʻo ka mea mua, hana mau ʻia ka huahana a ma ka pūnaewele.ʻOi aku ka mānoanoa o ka pā, ʻoi aku ka nui o ka hoʻopukapuka ʻana i ka ʻāpana a me nā lako wili, a ʻoi aku ka liʻiliʻi o ka waiwai a me ka hana.ʻO ka ʻoi aku ka lahilahi o ka pā, ʻo ia ka haʻahaʻa o kāna ratio hoʻokomo-puka;ʻO ka lua, ʻo ke kaʻina hana o ka huahana e hoʻoholo i kona mau pono a me nā hemahema.ʻO ka mea maʻamau, he kiʻekiʻe ka pololei o ka paipu kila i hoʻopaʻa ʻia, ka mānoanoa o ka paia, kiʻekiʻe i loko a me waho o ka ʻōlinolino o nā mea pono paipu kila (ʻo ka ʻōlinolino o ka ʻili o ka ʻili o ka pā kila), a hiki ke hoʻohālikelike ʻia.No laila, hoʻokomo ia i kona hoʻokele waiwai a me ka nani i ka hoʻohana ʻana i ka wai kaomi kiʻekiʻe, waena-haʻahaʻa.
Aia ka chlorine ion i ka hoʻohana ʻana.Loaʻa ka nui o nā ion chlorine, e like me ka paʻakai, ka hou, ka wai kai, ka makani kai, ka lepo, a me nā mea ʻē aʻe. ʻO ke kila kuhili ʻole e ʻino koke i mua o nā ion chloride, ʻoi aku ma mua o ke kila haʻahaʻa-carbon maʻamau.No laila, aia nā koi no ka hoʻohana ʻana i ke kila kila, a pono e holoi pinepine ʻia e wehe i ka lepo a mālama i ka maʻemaʻe a maloʻo.
ʻO 316 a me 317 mau kila kila (e ʻike i lalo no nā waiwai o 317 mau kila kila) he molybdenum i loaʻa nā kila kila.ʻOi aku ka kiʻekiʻe o ka molybdenum ma 317 stainless steel ma mua o ka 316 stainless steel.Ma muli o ka molybdenum i ke kila, ʻoi aku ka maikaʻi o ka hana holoʻokoʻa o kēia kila ma mua o 310 a me 304 stainless steel.Ma lalo o ke kūlana wela kiʻekiʻe, i ka wā i emi iho ai ka nui o ka sulfuric acid ma mua o 15% a ʻoi aku ka kiʻekiʻe ma mua o 85%, 316 stainless steel ka nui o nā hoʻohana.Loaʻa i ka 316 stainless steel maikaʻi ke kūpaʻa chloride corrosion, no laila e hoʻohana mau ʻia i ka moana kai.Me ka hoʻomohala ʻana i ka hoʻokele waiwai, ua ʻoi aku ka kaulana o ka hoʻohana ʻana i ka paipu kila kila.E lawe mai ia i nā loli hou ma nā kahua āpau.

316 paipu kila kila
Hoʻohana ʻia nā metala i ka ʻaila, kemika, ka lāʻau lapaʻau, ka meaʻai a me ka ʻoihana māmā
ʻO 316 ka paipu kila kila he ʻano o ke kila a puni ka lōʻihi, i hoʻohana nui ʻia i ka ʻaila, kemika, ka lāʻau lapaʻau, ka meaʻai, ka ʻoihana māmā, nā mea hana mechanical a me nā pipeline hoʻoili ʻoihana ʻē aʻe a me nā mea hana mechanical.Eia kekahi, i ka wā e like ai ke kulou a me ka ikaika torsional, maʻalahi ka paona, no laila hoʻohana nui ʻia e hana i nā ʻāpana mechanical a me nā hale ʻenekinia.Hoʻohana pinepine ʻia ia e hana i nā mea kaua maʻamau, barela, pūpū, etc.
ʻO ka nui o ka carbon carbon content o 316 stainless steel pipe he 0.03, hiki ke hoʻohana ʻia i nā noi kahi i ʻae ʻole ʻia ai ka annealing ma hope o ke kuʻi ʻana a koi ʻia ke kūpaʻa corrosion kiʻekiʻe.
ʻO 316 a me 317 mau kila kila (e ʻike i lalo no nā waiwai o 317 mau kila kila) he molybdenum i loaʻa nā kila kila.
ʻOi aku ka maikaʻi o ka hana holoʻokoʻa o kēia kila ma mua o 310 a me 304 stainless steel.I ke kiʻekiʻe wela, i ka wā i emi iho ai ka sulfuric acid ma mua o 15% a ʻoi aku ka kiʻekiʻe ma mua o 85%, 316 stainless steel ka nui o nā hoʻohana.
316 pā kila kila, i ʻike ʻia ʻo 00Cr17Ni14Mo2, kūpaʻa ʻino:
ʻOi aku ka maikaʻi o ka corrosion ma mua o 304 stainless steel, a he maikaʻi ke kūpaʻa corrosion i ke kaʻina hana o ka pulp a me ka pepa.
ʻOi aku ka maikaʻi o ka carbide precipitation resistance o 316 stainless steel ma mua o ka 304 stainless steel, a hiki ke hoʻohana ʻia ka pae wela ma luna.
Nā ʻano like ʻole: 316 paipu kila kuhiliʻole, 316 paipu ʻālohilohi, 316 paipu hoʻohiwahiwa kila, 316 paipu kuhili ʻole, 316 paipu kila kila, 304 paipu kila kila.
ʻO ka nui o ka carbon carbon content o 316L stainless steel pipe he 0.03, hiki ke hoʻohana ʻia i nā noi kahi i ʻae ʻole ʻia ai ka annealing ma hope o ke kuʻi ʻana a koi ʻia ke kūpaʻa corrosion kiʻekiʻe.
