Paipu 'Aha 'Aha 'Aha Kuhili 'ole
ʻO ke ʻano o nā paipu ke ʻano o nā paipu.He poepoe, huinahalike, rectangular, hexagonal a me hydraulic paipu i loko o na ano kuhiliʻole kila. Aia 304, 316 māka o austenitic kuhiliʻole kila i ka hapanui hoʻohana 'ia i loko o nāʻoihana.Aia kekahi mau ʻano paipu kila kila e like me ka duplex, ferritic, martensitic a me nā mea kila kila.
ʻO ke kila kila kila a me ka ʻūhā ʻāpana ʻehā i kapa ʻia ʻo ia ka paipu kila a i ʻole ka paipu hana.Hōʻike ʻia kēia ma ke ʻano he ʻāpana hollow structural a i ʻole HSS no ka pōkole.Hoʻohana ʻia no ka hoʻolālā ʻana, hiki ke kūʻai ʻia i nā ʻano ʻano like ʻole o ke kila a me nā ʻāpana.ʻO ka hana ʻana o ka paipu square like me ka hana ʻana o ka paipu akā hele ka huahana ma ke ʻano o ka hoʻohālikelike ʻana i nā kū, e hālāwai ana me kāna mau kikoʻī square square.
Hāʻawi ka ʻāpana keʻa huinahā o nā paipu i ka ikaika geometric maikaʻi.No laila, hoʻohana ʻia nā paipu i nā noi ikaika kiʻekiʻe.Loaʻa nā lawelawe kiʻekiʻe a me nā lawelawe wela e like me nā mea hoʻololi wela e hoʻohana pū ana i nā paipu.He ikaika ka paipu huinaha 316 ss a pale i ka corrosion.ʻO ka mea 316 he chromium, nickel a me molybdenum i ka haku mele.Hiki i kēia hui ke hoʻonui i ke kūpaʻa corrosion me 215MPa haʻahaʻa haʻahaʻa ikaika 505MPa liʻiliʻi tensile ikaika.Hiki i nā paipu ke hana ma lalo o nā mahana a hiki i 870 degere Celsius.Hoʻohana ka SS Square Welded Tube i nā hihia i ka aila a me ke kinoea, ka ʻaila, ka petrochemical, ke kūkulu ʻana a me nā noi hoʻolālā pū kekahi.Aia nā papa kiʻekiʻe e like me ka SS317 Square Tubes i hana ʻia me ka 317 grade material nona ka ikaika tensile haʻahaʻa he 517MPa.He mea pono i nā noi koi ikaika kiʻekiʻe.Hoʻohana ʻia ka ASTM A270 Seamless Square Tube i ke kaomi kiʻekiʻe, nā lawelawe wela kiʻekiʻe a me nā lawelawe corrosive maʻamau.
Kuhiliʻole Steel Seamless Square Tubing, Ka Hana Hana
Hoʻomākaukau kila pōʻai → hoʻomehana → ka ʻōwili wela → ʻoki poʻo → pickling → polishing → lubrication → kaʻina ʻōwili anuanu → degreasing → hoʻoponopono wela → hoʻoponopono → ʻoki ʻana i ka paipu → pickling → ka nānā ʻana o ka huahana.
ʻO ke kila kila maʻemaʻe ʻaʻohe paipu pāpaʻa ，Ka Hana Hana
Hiki i ka metala ke hana me ka oxygen i ka lewa e hana i kahi kiʻiʻoniʻoni oxide ma ka ʻili.ʻO ka hao hao i hoʻokumu ʻia ma ke kila kalapona maʻamau e hoʻomau i ka oxidize, e hoʻonui ana i ka ʻinoʻino a hana i nā lua.Hiki ke hana i kēia me ka pena a i ʻole ka pale ʻana i ka oxidation-resistant no ka pale ʻana i ka ʻili o ke kila kalapona, akā he kiʻi ʻoniʻoni wale nō kēia uhi.Inā pōʻino ka uhi, hoʻomaka ke kila ma lalo e ʻōpala hou.E pili ana paha ka paipu kila kila me ka chromium ma loko o ke kila.Ke piʻi ka chromium i loko o ke kila i ka 12%, ʻo ka ʻili o ka paipu kila kila e hoʻohua i kahi papa o ka passivation a me ka chromium waiwai waiwai nui e pale i ka ʻili a pale i ka reoxidation hou aʻe.He lahilahi loa kēia ʻāpana oxide, kahi e ʻike ʻia ai ka ʻōlinolino maoli o ka ʻili kila, e hāʻawi ana i ke kila kila i kahi ʻano ʻokoʻa.Inā hoʻopōʻino ke kiʻi chromium i hoʻokahi manawa, ʻo ka chromium i ke kila a me ka oxygen i ka lewa e hoʻohou i ka kiʻi passivation, e hoʻomau i ka pāʻani i kahi hana pale.I loko o kekahi mau kaiapuni kūikawā, e ʻike ʻia ke kila kuhiliʻole kekahi ʻino a me ka hāʻule ʻole, akā ʻokoʻa ke kila kuhiliʻole a me ke kila kalapona, ʻaʻole e ʻike ʻia ke ʻano ʻino a me ka hāʻule ʻole, no laila ʻaʻole i manaʻo ʻia ka ʻae ʻana o ka corrosion no ka paipu kila kila.
