1. Hoʻolauna pōkole o ka paipu kūkulu

Hoʻohana ʻia ka paipu humuhumu no ka hoʻonohonoho ʻana (GB/T8162-2008) no ka hoʻonohonoho maʻamau a me ka hoʻonohonoho mechanical o ka paipu humuhumu. Ua māhele ʻia ka paipu kila humuhumu i nā ʻano hoʻohana like ʻole.

ʻO ka paipu humuhumu kila kila no ka hoʻolālā ʻana (GB/T14975-2002) he paipu humuhumu wela (extruded, hoʻonui ʻia) a huki anu ʻia (ʻōwili ʻia) i hana ʻia me ke kila kila i hoʻohana ʻia i nā kemika, ʻaila, lole, lāʻau lapaʻau, meaʻai, mīkini a me nā ʻoihana ʻē aʻe, nā paipu kūpaʻa i ka corrosion a me nā ʻāpana a me nā ʻāpana kūkulu.

Hoʻohana nui ʻia ʻo GB/T8162-2008 (paipu humuhumu no ke kūkulu ʻana) no ke kūkulu maʻamau a me ke kūkulu mechanical. ʻO kāna mea koho (lama): kila kalapona 20, kila 45, Q235, kila hui Q345, 20Cr, 40Cr, 20CrMo, 30-35CrMo, 42CrMo a pēlā aku.

Paipu kila humuhumu ʻole

Ma muli o ke ʻano o kāna hana ʻana he ʻokoʻa, ua māhele ʻia i loko o ka paipu kila wili ʻole wela (extruded) a me ka paipu kila wili ʻole anu (rolled) ʻelua ʻano. Ua māhele ʻia ka paipu kila wili ʻole anu (rolled) i ʻelua ʻano.

A. Ka nānā ʻana i ke kahe o ke kaʻina hana

ʻŌwili wela (paipu kila wili ʻole i hoʻopuka ʻia): ʻōwili paipu poepoe → hoʻomehana → perforation → ʻōwili keʻa ʻekolu ʻōwili, ʻōwili mau a i ʻole extrusion → wehe ʻana i ka paipu → nui (a i ʻole ka hōʻemi ʻana) → hoʻomaʻalili → paipu hakahaka → hoʻopololei → hoʻāʻo kaomi wai (a i ʻole ka ʻike ʻana i nā hemahema) → māka → mālama.

ʻO ke kaha kiʻi anu (ʻōwili) o ke kila kila humuhumu: ʻōwili poepoe → hoʻomehana → perforation → poʻomanaʻo → annealing → pickling → aila (plating keleawe) → kaha kiʻi anu multi-pass (ʻōwili anu) → paipu hakahaka → mālama wela → hoʻopololei → hoʻāʻo kaomi wai (ʻike kīnā) → māka → mālama.

2. Nā Kūlana

1, GB: paipu kila humuhumu no ke ʻano: GB8162-2008 2, paipu kila humuhumu no ka lawe ʻana i ke wai: GB8163-2008 3, paipu kila humuhumu no ka paila: GB3087-2008 4, paipu humuhumu kiʻekiʻe no ka paila: 5, lako mea hoʻomomona kemika no ka paipu kila humuhumu kiʻekiʻe: GB6479-2000 6, ʻeli honua no ka paipu kila humuhumu: YB235-70 7, ʻeli ʻaila no ka paipu kila humuhumu: YB528-65 8, paipu kila humuhumu nahā ʻaila: 10. Paipu kila humuhumu no ke kaʻa hapa-ʻauamo: GB3088-1999 11. Paipu kila humuhumu no ka moku: GB5312-1999 12.13, nā ʻano paipu metala like ʻole 16Mn, 27SiMn, 15CrMo, 35CrMo, 12CrMov, 20G, 40Cr, 12Cr1MoV, 15CrMo

Eia kekahi, Aia kekahi GB/T17396-2009 (paipu kila humuhumu wela no ka prop hydraulic), GB3093-1986 (paipu kila humuhumu kiʻekiʻe no ka mīkini diesel), GB/T3639-1983 (paipu kila humuhumu anu a humuhumu anu paha), GB/T3094-1986 (paipu kila humuhumu anu, paipu kila ʻano kūikawā), GB/T8713-1988 (paipu kila humuhumu me ke anawaena kūloko pololei no nā cylinders hydraulic a me pneumatic), GB13296-1991 (paipu kila kila humuhumu no nā paila a me nā mea hoʻololi wela), GB/T14975-1994 (paipu kila kila humuhumu no ka hoʻohana ʻana i ke kūkulu ʻana), GB/T14976-1994 (paipu kila kila humuhumu me ke anawaena kūloko pololei no nā cylinders hydraulic a me pneumatic) Paipu kila kila humuhumu no ka lawe ʻana i ke wai GB/T5035-1993 (paipu kila humuhumu no ke kaʻa (axle bushing), API SPEC5CT-1999 (kikoʻī no ka casing a me ka tubing), etc.

2, Kūlana ʻAmelika: ASTM A53 — ASME SA53 — Papa hana nui a i ʻole ke kila o ka paila a me ke kīʻaha kaomi: A53A, A53B, SA53A, SA53B

ʻO ke ʻano kaumaha o ka paipu humuhumu ʻole: [(ke anawaena waho - ka mānoanoa o ka paia)* ka mānoanoa o ka paia]*0.02466=kg/ m (kaumaha no ka mika)
