No ka aila a me ke kinoea pipelines, pipelines e pono e hoʻomaʻemaʻe, a kanu i loko o ka lepo, e hoʻohana a pau-pass a pau-welded poepoe kiwikā;no ka kanu ʻana i ka lepo, e koho i nā kīwī pōlele āpau āpau i welded a flanged;nā paipu lālā , E koho i ka pili flange, ka hui kuʻi, ka piha piha a i ʻole ka hoʻemi ʻana o ke anawaena pōlele.
No ka pipeline kaʻa a me nā lako mālama o ka ʻaila i hoʻomaʻemaʻe ʻia, e hoʻohana i nā kīwī pōpō flanged.
No nā paipu kinoea o ke kūlanakauhale a me ke kinoea maoli, e hoʻohana i nā kiwi pōpō lana me ka hoʻopili flange a me ka pilina o loko.
I ka ʻōnaehana pipeline oxygen i loko o ka ʻōnaehana metallurgical, pono e hoʻohana ʻia kahi pahu pōpō paʻa i hana ʻia i ka degreasing koʻikoʻi a me ka pili flanged.
No nā ʻōnaehana paipu haʻahaʻa haʻahaʻa a me nā mea hana, pono e hoʻohana ʻia nā kiwi pōpō haʻahaʻa haʻahaʻa me nā pāpale.I loko o ka pipeline nenoai o ka catalytic cracking unit o ka aila hoʻomaʻemaʻe hui, hiki ke koho i ka lifter-type kinipoe kiwikā.
I loko o nā lako a me nā ʻōnaehana paipu o nā media corrosive e like me ka waikawa a me ka alkali i nā ʻōnaehana kemika, pono e hoʻohana i nā kiwi pōpō kila kila a pau i hana ʻia me ka austenitic stainless steel a me ka polytetraoxyethylene ma ke ʻano he noho a me ke apo hoʻopaʻa.
Hiki ke hoʻohana ʻia nā kiwi pōpō metala hoʻopaʻa metala i nā ʻōnaehana paipu a i ʻole nā ​​​​mea hana no ka media wela kiʻekiʻe i nā ʻōnaehana metallurgical, nā ʻōnaehana mana, nā mea hoʻokomo petrochemical, a me nā ʻōnaehana hoʻomehana kūlanakauhale.
