Inā makemake ʻoe e ʻike i ka ʻike hou aku, e like me ka ʻōlelo kūʻai, nā huahana, nā hoʻonā, a me nā mea ʻē aʻe, phoʻolimalimae leka uila mai iā mākou ma ka pūnaewele.
He mea kūʻai waiwai ʻo Tianjin Sanon Steel Pipe Co., Ltd. Aia kā mākou hale hana ma ke kūlanakauhale ʻo Cangzhou, ma ka moku ʻo Hebei. ʻO kā mākou kumu waiwai nuinā paipu paila, a ʻo nā mea i koho ʻiaASTM A335 P5/P11/P91/P92,ASME SA-106/SA-106MGR.B,GB/T 3087-200810#/20#. ʻO nā mea hana i koho ʻia no nā paipu paipu, ʻo iaAPI 5L,API 5CT, nā mea hana i koho ʻia no nā paipu haki ʻailaGB/T 9948he 15MoG/12CrMoVG. Hōʻike ʻo GB/T 6479-2013 i nā mea 10#/20#, nā paipu hoʻololi wela SA179/SA210/SA192, a pēlā aku, nā paipu mīkini GB/T 8162 i nā mea 10#/20#/Q345/42CrMo, EN10210 i nā mea S355JOH/S355J2H, nā paipu pahu kinoea GB1 8248, i nā mea 34CrMo4/30CrMo.
Nā ʻano huahana paipu kila ASTM A333/A333M a me ka hoʻolauna mea
ʻIke Kūlana Maʻamau
ʻO ASTM A333/A333M ke kūlana "paipu kila seamless a welded no ka mahana haʻahaʻa" i hoʻokumu ʻia e ka American Society for Testing and Materials, kahi kūpono no nā ʻōnaehana paipu kaomi ma nā wahi mahana haʻahaʻa.
Nā palena huahana

Nā koi hana
Kaʻina hana: seamless a welded paha (akā ʻo Gr.6 ka mea maʻamau e koi i ka seamless)
Ka mālama wela: ka hoʻomaʻamaʻa ʻana a i ʻole ka hoʻomaʻamaʻa ʻana a me ka hoʻoikaika ʻana
Hoʻāʻo ʻole e luku: 100% hoʻāʻo ultrasonic a i ʻole eddy current
Hoʻāʻo kaomi hydraulic: maʻamau 1.5 mau manawa o ke kaomi hana
Hoʻokaʻawale mea
Loaʻa iā ASTM A333/A333M nā ʻano mea he nui, a ʻokoʻa ke ʻano kemika o kēlā me kēia ʻano:
1. Papa 1
Kalapona (C): ≤0.30%
Manganese (Mn): 0.40-1.06%
ʻO ka phosphorus (P): ≤0.025%
Sulfur (S): ≤0.025%
Silika (Si): ≥0.10%
2. Papa 3
ʻO ka ʻike o Nickel (Ni) ma kahi o 3.5%, me ka paʻakikī o ka mahana haʻahaʻa maikaʻi
3. Papa 6
Kalapona (C): ≤0.30%
Manganese (Mn): 0.29-1.06%
ʻO ka phosphorus (P): ≤0.025%
Sulfur (S): ≤0.025%
Silika (Si): ≥0.10%
4. Gr.8
Mea kila kila Austenitic, maʻamau 304 a i ʻole 304L
5. Papa 9
ʻO ka nui o ka Nickel (Ni) ma kahi o 1.5%, ma waena o Gr.3 a me Gr.6
6. Gr.10
ʻO ke kila kila haʻahaʻa e loaʻa ana ka molybdenum (Mo) e hoʻomaikaʻi i ke kūpaʻa ʻana i ka pala
Ka laulā mahana kūpono o kēlā me kēia papa
| Papa | Ka mahana hana haʻahaʻa loa |
| Papa 1 | -45℃ |

Wehewehe hou aku
1. ʻO Gr.6 ka papa i hoʻohana nui ʻia, kūpono loa no nā wahi haʻahaʻa haʻahaʻa e like me LNG (-162 ℃)
2. ʻO ke koho ʻana o nā māka like ʻole e pili ana i ka mahana hoʻolālā, nā ʻano waena a me nā noʻonoʻo kumukūʻai
3. Hoʻokomo ʻia nā papa āpau o nā paipu kila i nā hoʻāʻo hopena haʻahaʻa haʻahaʻa e hōʻoia i ko lākou paʻakikī
4. No nā paipu kila i hoʻopaʻa ʻia, pono ka mālama wela kūpono ma hope o ka hoʻopaʻa ʻana e hoʻihoʻi i nā waiwai mea
5. I ke kūʻai ʻana, pono e koho ʻia ka papa mea kūpono e like me ke kaiapuni noi kikoʻī, a pono e hōʻoia pono ʻia ka palapala hōʻoia mea a me ka hōʻike hoʻāʻo.
