316l kuhiliʻole kila seamless kila paipu
ʻO 304 kila kila he mea maʻamau i loko o ke kila kila, me ka mānoanoa o 7.93 g/cm³; ua kapa ʻia ʻo ia he 18/8 stainless steel i loko o ka ʻoihana, ʻo ia hoʻi he ʻoi aku ma mua o 18% chromium a ʻoi aku ma mua o 8% nickel; ʻO ke kūpaʻa wela kiʻekiʻe o 800 ℃, ka hana hoʻoponopono maikaʻi, ka paʻakikī kiʻekiʻe, hoʻohana nui ʻia i ka ʻoihana a me ka ʻoihana hoʻonaninani hale a me ka meaʻai a me ka ʻoihana olakino. Eia naʻe, pono e hoʻomaopopo ʻia i ka hoʻohālikelike ʻia me ke kila kila 304 maʻamau, ʻoi aku ka paʻakikī o ka meaʻai-304 stainless steel. No ka laʻana, ʻo ka wehewehe honua o 304 stainless steel he 18% -20% chromium, 8% -10% nickel, akā ʻo ka meaʻai-grade 304 stainless steel he 18% chromium a me 8% nickel, e ʻae ana i nā fluctuations i loko o kahi ākea, a E kaupalena i ka ʻike o nā metala kaumaha like ʻole. I nā huaʻōlelo ʻē aʻe, ʻaʻole pono ke kila kila 304 ka meaʻai 304 kila kila
ʻO nā paipu kila kila ʻole nā paipu kila i kū i nā mea hoʻoheheʻe nāwaliwali e like me ka ea, ka mahu, a me ka wai, a me nā mea hoʻoheheʻe kemika e like me nā waikawa, alkalis, a me nā paʻakai. ʻIke ʻia hoʻi ʻo ka paipu kila ʻakika-kūpono.
ʻO ka pale ʻana i ka corrosion o nā paipu seamless kila ma muli o nā mea hoʻohui i loko o ke kila. ʻO Chromium ka mea kumu no ka pale ʻana i ka ʻino o ke kila kila. Ke piʻi ka chromium i loko o ke kila ma kahi o 12%, pili ka chromium me ka oxygen i loko o ka corrosive medium e hana i kahi kiʻi ʻoniʻoni ʻokiʻoki loa (self-passivation film) ma ka ʻili o ke kila. , Hiki ke pale i ka corrosion hou aku o ka matrix kila. Ma waho aʻe o ka chromium, ʻo nā mea hoʻohui maʻamau i hoʻohana ʻia no nā paipu seamless steel me ka nickel, molybdenum, titanium, niobium, copper, nitrogen, etc., e hoʻokō i nā koi o nā hoʻohana like ʻole no ka hoʻolālā a me ka hana o ke kila kila.
ʻO ke kila kila kila ʻole he kila pōʻai lōʻihi, hoʻohana nui ʻia i ka petroleum, kemika, lāʻau lapaʻau, meaʻai, ʻoihana māmā, mea hana mīkini a me nā pipeline ʻoihana ʻē aʻe a me nā ʻāpana hana mechanical. Eia kekahi, i ka wā e like ai ke kulou a me ka ikaika torsion, ʻoi aku ka maʻalahi o ke kaumaha, no laila hoʻohana nui ʻia i ka hana ʻana i nā ʻāpana mechanical a me nā hale ʻenekinia. Hoʻohana pinepine ʻia e hana i nā mea kaua maʻamau, barela, pūpū, etc.
Loaʻa iā ia nā hana hana penei:
a. Hoʻomākaukau kila pōʻai; b. ʻO ka hoʻomehana; c. Hoʻopiʻi wela; d. E ʻoki i ke poʻo; e. Pickling; f. wili; g. Lubrication; h. ʻO ka hana ʻōwili anuanu; i. Degreasing; j. Hoʻoponopono wela wela; k. Hoʻopololei; l. ʻOki i ka paipu; m. Pickling; n. Hōʻike huahana.
