316l kuhiliʻole kila seamless kila paipu

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 he 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.
