Hiki ke hana ʻia nā hoʻomaʻamaʻa wela ma waho o nā mea i hāʻawi ʻia ma ka papa ma ka ʻaelike ma waena o ka mea kūʻai aku a me ka mea hana.
ʻAno Hoʻopau Paipu
E hoopau ia na paipu me na welau palahalaha.
Inā hōʻike ʻia kahi hopena beveled, ʻo ke ʻano o ka hopena tapered o nā paipu me ka mānoanoa pā ≤ 22 mm e kūlike me 30-35 °, a ʻo ka laulā bevel o ka ʻaoʻao paipu kila he max 2.4mm.
Nā Mea Kemika o JIS G 3455
E kulike ana ka noonoo ana me ka JIS G 0320. E kulike ka noonoo ana me JIS G 0321.
E kulike ana na waiwai anaana wela i keia mau koi:

ʻAʻole pono nā waiwai i kālailai ʻia o ka huahana i nā koina ma ka papaʻaina, akā ʻo ka laulā hoʻomanawanui o kēlā me kēia mea pono e like me nā koi o ka Papa 3 o JIS G 3021.
Waiwai Mekanika o JIS G 3455
Pono nā koi maʻamau no nā hoʻokolohua mechanical e like me nā māhele 7 a me 9 o JIS G 0404. Pono nā ʻano laʻana no nā hoʻokolohua mechanical e like me ka Papa A o JIS G 0404, Paukū 7.6.
Ka ikaika uʻi, ka lae hua a i ʻole ke koʻikoʻi hōʻoia, a me ka elongation
Pono ke ʻano hoʻāʻo e like me nā kūlana ma JIS Z 2241.
No nā paipu i hoʻāʻo ʻia me ka hoʻohana ʻana i ka specimen No. 12 a i ʻole No. 5, e hoʻokō ka elongation i nā koi o ka Papa 5.

Hiki ke hoʻokuʻu ʻia ka hoʻāʻo ma ka manaʻo o ka mea hana i ka wā e māʻona ai nā paipu i ke kūpaʻa palahalaha i kuhikuhi ʻia.
Hoʻonoho ʻia ke kikoʻī ma waena o ʻelua mau papa a palahalaha i ka hoʻoemi ʻana a hiki i ka mamao H ma waena o nā paepae i ka waiwai i kuhikuhi ʻia.A laila nānā ʻia ke ʻano no nā māwae.

Ho'āʻo Bendability
E pili ana i nā paipu me ke anawaena o waho ≤50 mm e like me ka mea i ʻōlelo ʻia e ka mea kūʻai.
ʻAʻohe māwae ka mea hoʻohālike i ka wā e pio ai ma kahi kihi o 90° me ke anawaena o loko o 6 manawa o ke anawaena o waho o ka paipu.E ana ʻia ka ʻoki piʻo ma ka hoʻomaka ʻana o ka piʻo.
ʻO ka hoʻāʻo Hydrostatic a i ʻole ka hoʻāʻo Nondestructive
Pono e hana ʻia kahi hoʻāʻo hydrostatic a i ʻole luku ʻole ma kēlā me kēia paipu.
Hoʻāʻo Hydrostatic
E hoʻopaʻa i ka paipu ma ka liʻiliʻi ma lalo o ke kaomi hoʻāʻo hydrostatic liʻiliʻi loa no ka liʻiliʻi 5 kekona a nānā i hiki i ka paipu ke kū i ke kaomi me ka leakage.
Ke hōʻike ʻole ka mea kūʻai aku i ke kaomi hoʻāʻo, a i ka wā e kau ʻia ai ka paipu i ka haʻahaʻa haʻahaʻa haʻahaʻa hydrostatic i hāʻawi ʻia, hiki i ka paipu ke kūpaʻa me ka leakage.

Mai kona hoʻokumu ʻana i ka makahiki 2014, ua lilo ʻo Botop Steel i mea hoʻolako alakaʻi i ka paipu kila carbon ma Northern China, i ʻike ʻia no ka lawelawe maikaʻi loa, nā huahana kiʻekiʻe, a me nā hoʻonā 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 kila stainless austenitic, i hoʻokō ʻia e hoʻokō i nā koi o nā papahana pipeline like ʻole.
