Mai kona hoʻokumu ʻana i ka makahiki 2014,Ke kila Botopua lilo i mea hoʻolako alakaʻi o ka paipu kila kalapona ma Northern China, i ʻike ʻia no ka lawelawe maikaʻi loa, nā huahana kiʻekiʻe, a me nā hāʻina piha.
Hāʻawi ka hui i nā ʻano paipu kila kalapona a me nā huahana pili, me ka seamless, ERW, LSAW, a me ka paipu kila SSAW, a me ka laina piha o nā paipu paipu a me nā flanges.ʻO kāna mau huahana kūikawā pū kekahi me nā mea kila kiʻekiʻe a me nā austenitic stainless steel, i hana ʻia e hoʻokō i nā koi o nā papahana pipeline like ʻole.
ʻO nā paipu kila ASTM A53 hiki ke hoʻopaʻa ʻia a welded paha.
ʻO ke ʻano hana hana ʻole (Type S) kahi hana wela o ke kila a, inā pono, hoʻopau anuanu o ka huahana tubular hana wela e hoʻokō i ke ʻano, nā ana, a me nā waiwai.
Ma ka maʻamau ASTM A53, nā koi hoʻohui kemika no Type S aʻAno EʻOkoʻa nā paipu kila, ʻoiai ʻokoʻa nā koi hoʻohui kemika no Type F.

ʻAʻole pono e hoʻokō ʻia nā paipu kila ʻole i ka hoʻāʻo palahalaha.
Inā koi ʻia e ka ʻaelike, hiki ke hoʻokō ʻia ka hoʻokolohua e like me ke kaʻina hana ma S1.
ʻO nā nui a pau o nā paipu kila maʻemaʻe e mālama i kahi waiwai paʻi wai me ka leaka ʻole no ka liʻiliʻi 5 kekona.
Hiki ke loaʻa ke kaomi hoʻāʻo no nā paipu kila ma ka Papa X2.2.
Hiki ke loaʻa nā kaomi hoʻāʻo no nā paipu kila i hoʻopaʻa ʻia a hui ʻia ma ka Papa X2.3.
Hiki ke hoʻohana ʻia ma ke ʻano he koho i ka hoʻāʻo hydrostatic.
ʻO ka lōʻihi holoʻokoʻa o kēlā me kēia paipu seamless e hoʻokō ʻia i kahi hoʻāʻo uila non-destructive e like meE213, E309, a i ʻoleE570.
I ke kūʻai ʻana iā ASTM A53, pono e hoʻokō ka nui o ka paipu kila i nā koi aʻe.

Hōʻike ka maʻamau ʻo ASTM A53 i nā koi no ke kūlana paipu ʻeleʻele a me ka uhi galvanized wela o nā paipu kila.
Paipu ʻEleʻele
ʻO ka paipu ʻeleʻele e pili ana i ke kūlana o ka paipu kila me ka ʻole o ka mālama ʻana i ka ʻili.
Hoʻohana pinepine ʻia nā paipu ʻeleʻele ma nā wahi pōkole o ka mālama ʻana, maloʻo ke kaiapuni a ʻaʻole corrosive, a ʻoi aku ka haʻahaʻa o ke kumukūʻai no ka mea ʻaʻohe uhi.
ʻO ka uhi ʻana i ka weuweu wela
Hoʻohana pinepine ʻia nā paipu Galvanized, ʻike ʻia hoʻi he paipu keʻokeʻo, i loko o nā wahi humid a corrosive.
ʻO ka zinc i loko o ka zinc coating hiki ke loaʻa i kekahi papa o ka zinc ma ASTM B6.
Pono ka paipu galvanized mai nā wahi i uhi ʻole ʻia, nā ʻōhū, ka waiho ʻana o ka flux, a me ka hoʻokomo ʻana i ka lepo.ʻAʻole ʻae ʻia nā puʻupuʻu, projections, globules, a i ʻole nā waiho nui o ka zinc e hoʻopilikia i ka hoʻohana ʻana i ka mea.
ʻAʻole emi ka zinc ma lalo o 0.55 kg/m² [ 1.8 oz/ft² ].
Nā Paʻi ʻē aʻe
Ma waho aʻe o ka paipu ʻeleʻele a me ka galvanized coating, nā ʻano uhi maʻamaupena, 3LPE, FBE, a me nā mea'ē aʻe. Hiki ke kohoʻia keʻano o ka uhi kūpono e like me nā koi kiko'ī o ke kaiapuni hana.
ʻO ka hāʻawi ʻana i ka ʻike ma lalo nei e ʻoi aku ka maikaʻi a me ka pololei o kāu kaʻina kūʻai.
