ʻO ka hoʻomohala ʻana o ka mākeke hoʻolako ʻoihana paipu kila

He ʻāpana hakahaka ka paipu kila, a ʻoi aku ka nui o kona lōʻihi ma mua o ke anawaena a i ʻole ke anapuni o ke kila.E like me ke ʻano o ka ʻāpana, ua māhele ʻia i loko o ka pōʻai, square, rectangular a me nā paipu kila kūikawā;E like me ka mea, ua maheleia i kalapona structural kila paipu, haʻahaʻa alloy structural kila paipu, alloy kila paipu a composite kila paipu;Hoʻokaʻawale ʻia i nā paipu kila no ka hoʻouna ʻana i nā pipelines, nā hale ʻenekinia, nā mea wela, nā ʻoihana petrochemical, nā mīkini hana, geological drilling, nā mea hana kiʻekiʻe, etc;Wahi a ke kaʻina hana, ua māhele ʻia i ka paipu kila seamless a me ka paipu kila welded.Hoʻokaʻawale ʻia ka paipu kila maʻemaʻe i ka ʻōwili wela a me ka ʻōwili anu (drawing), a ua māhele ʻia ka paipu kila welded i ka paipu kila wili pololei a me ka paipu kila wili.

ʻO Kina ka mea hana nui o nā paipu kila ma ka honua.I ka makahiki 2020, he 89.5427 miliona tons ka huina aupuni, me ka piʻi ʻana o ka makahiki he 3.73%, e helu ana ma kahi o 60% o ka puka honua.I ka manawa like, pili pono ka pōʻai hoʻolako o ka ʻoihana paipu kila i ka loaʻa kālā o ka ʻoihana, ka hoʻokele aupuni a me ka ʻoihana hana.No laila, ma lalo o ka hoʻokō ʻana o ka "14th ʻelima makahiki hoʻolālā" a me ke kulekele hoʻolālā hou, e hoʻomau ka hoʻolako ʻana i ka ʻoihana paipu kila o Kina i ka ulu ulu.
