Kiʻekiʻe kuhiliʻole kila paipu huinahalike
ʻO ke kila kila kila he ʻano hao lōʻihi. No ka mea, he huinaha ka pauku, ua kapaia ka paipu huinahalike. Hoʻohana ʻia ka nui o nā pipelines no ka lawe ʻana i nā wai, e like me ka aila, ke kinoea maoli, ka wai, ke kinoea, ka mahu, a me nā mea ʻē aʻe, i ka wā e like ai ke kulou a me ka ikaika torsional, ua maʻalahi ke kaumaha, no laila ua ākea lākou. hoʻohana ʻia i ka hana ʻana i nā ʻāpana mechanical a me nā hale ʻenekinia.
Ka hoʻokaʻawale ʻana o ke kila kila paipu ʻāpana: hoʻokaʻawale ʻia ka paipu square i ka seamless steel pipe a me ka welded steel pipe (slotted pipe). E like me ke ʻano o ka ʻāpana, hiki ke hoʻokaʻawale ʻia i nā paipu square a me rectangular. Hoʻohana nui ʻia nā paipu kila pōʻai, akā aia kekahi mau paipu kila kūikawā e like me semicircular, hexagonal, equilateral triangle a me octagonal.
No ka paipu kīhāhā kila kila e lawe ana i ke kaomi wai, e hoʻokō ʻia ka hoʻāʻo hydraulic e nānā i kona kūpaʻa a me ka maikaʻi. Kūpono ia inā ʻaʻohe leakage, pulu a hoʻonui paha ma lalo o ke kaomi i kuhikuhi ʻia. Pono kekahi mau paipu kila i ka ho'āʻo crimping, flaring test, flattening test, etc. e like me ke kūlana a i ʻole nā koi o ka mea noi.
Hōʻike o ka pahu huinaha: 5 * 5 ~ 150 * 150 mm mānoanoa: 0.4 ~ 6.0 mm
Mea paipu huinaha: 304, 304L, TP304, TP316L, 316, 316L, 316Ti, 321, 347h, 310S
Hiki i nā 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 corrosion a hoʻopau i nā lua. Hiki i kēia ke hoʻohana i ka pena a i ʻole ka oxidation metala pale no ka electroplating e pale i ka ʻili o ke kila kalapona, akā ʻo kēia ʻāpana pale he kiʻi ʻoniʻoni wale nō. Inā pōʻino ka papa pale, e hoʻomaka hou ke kila o lalo e ʻōpala. E pili ana paha ka paipu kila kila me ka chromium i loko o ke kila. Ke piʻi ka chromium ma ke kila i ka 12%, ua hoʻokumu ʻia kahi papa o ka passivated a me ka dense chromium rich oxide ma ka ʻili o ka paipu kila kila i ka lewa e pale i ka ʻili a pale i ka reoxidation hou. He lahilahi loa keia papa oxide. Ma o ia mea, hiki iāʻoe keʻike i ka'ōlinolino maoli o kaʻili kila, kahi e loaʻa ai i ke kila kila keʻano kūikawā. Inā pōʻino ke kiʻi chromium, e hana hou ka chromium i ke kila a me ka oxygen i ka lewa i ka kiʻi passive e hoʻomau i ka hana pale. Ma kekahi mau kaiapuni kūikawā, e hāʻule ana ke kila kuhiliʻole ma muli o kekahi corrosion kūloko, akā ʻaʻole e like me ke kila kalapona, ʻaʻole e hāʻule ke kila kuhili ma muli o ke ʻano ʻino like ʻole, no laila, ʻaʻohe kumu o ka ʻae ʻana no nā paipu kila kila.
