1. Ka noi ʻana o ka mākeke honua
Hoʻohana nui ʻia nā paipu cylinder paipu kila Seamless i ka mālama ʻana a me ka halihali kinoea kiʻekiʻe, a ʻo nā mākeke nui e komo pū ana:
Kinoea ʻoihana (oxygen, nitrogen, argon, a pēlā aku):
Mea Hana: 34CrMo4, 30CrMo (kila metala ikaika kiʻekiʻe)
Hoʻohana: nā pahu kinoea kiʻekiʻe-kaomi ma ka hana ʻana, kemika, ka hoʻoheheʻe ʻana a me nā ʻoihana ʻē aʻe.
Kinoea ikehu (CNG, LNG, hydrogen):
Mea Hana: 34CrMo4, XCrMo4 (kū'ē ki'eki'e, kū'ē wela ha'aha'a)
Hoʻohana: nā pahu CNG kaʻa, nā pahu mālama LNG, ka mālama ʻana i ka ikehu hydrogen a me ka halihali.
Kinoea lapaʻau a me ke kinoea ʻai:
Mea Hana: 316L kila kila (kū'ē i ka palaho, ho'oma'ema'e ki'eki'e)
Hoʻohana: nā paukū oxygen lapaʻau, nā paukū CO₂ papa meaʻai.
Nā pahu kinai ahi a me nā pahu luʻu:
Mea Hana: 4130, 37Mn (paʻakikī kiʻekiʻe, kūpaʻa luhi)
Hoʻohana: nā mea hanu ahi, nā paukūʻoloka luʻu.
2. Ka loiloi koi mākeke
(1) Nā mea hoʻokele ulu mākeke honua
Ka hoʻololi ʻana o ka ikehu: ʻO ka piʻi ʻana o ke koi no ka ikehu maʻemaʻe e like me ka hydrogen, CNG/LNG, a me nā mea ʻē aʻe, e hoʻoulu ai i ka ulu ʻana o ka mākeke cylinder kinoea kiʻekiʻe.
Ka hoʻomohala ʻoihana: Ua ulu mau ke koi no nā pahu kinoea kiʻekiʻe ma nā ʻoihana hana, kemika, a me nā ʻoihana lapaʻau.
Hoʻonui ʻana i nā lula a me nā kūlana: Ua hoʻonui ʻo ʻEulopa a me ʻAmelika Hui Pū ʻIa (DOT, TPED) a me ʻĀsia (GB, JIS) i nā koi palekana no nā pahu kinoea, e hoʻokele ana i ke koi no nā paipu humuhumu kiʻekiʻe.
(2) Nā ʻano koi o ka mākeke kūloko
Mākeke ʻEulopa:
E hahai pono i nā kūlana EN 1964 a me PED (Pressure Equipment Directive), a makemake i nā mea 34CrMo4 a me XCrMo4.
Ke ulu wikiwiki nei ke koi no ka ikehu hydrogen a me nā pahu kinoea CNG.
Mākeke ʻAmelika ʻĀkau:
Hoʻohana nui ʻia ke kūlana ASTM A519 (4130/4140), a he nui ke koi no nā pahu kinoea CNG kaʻa.
ʻO ka ʻoihana aila a me ke kinoea ke kumu o ke koi no nā cylinders kinoea kiʻekiʻe.
Mākeke ʻĀkia (Kina, India, Iapana a me Kōlea Hema):
Kina: ʻO ke kūlana GB 18248 ka mea nui, 34CrMo4, 37Mn ke koi nui ʻia, a ke ulu wikiwiki nei ka mākeke cylinder CNG/LNG.
ʻInia: Ke ulu nei nā mākeke kinoea ʻoihana a me nā mākeke kaʻa CNG, e hoʻokele ana i ka lawe ʻia mai o nā paipu cylinder.
| Kahua noi | Nā mea maʻamau | hoʻokō i nā kūlana | Nā ʻano |
| Paukū kinoea ʻoihana | 34CrMo4,30CrMo | ISO 9809, IS 7285 | Ikaika kiʻekiʻe Kū i ke kaomi kiʻekiʻe |
| Pahu kinoea CNG | 34CrMo4, XCrMo4 | EN 1964, ISO 11439 | Anti-luhi Ke kū'ē wela haʻahaʻa |
| Pahu kinoea LPG | 37Mn, 4130 | ʻO IS 7285, DIN 17200 | ʻAno hoʻokele waiwai Pili i ke kaomi waena a me ke kiʻekiʻe |
| Paukū kinoea lapaʻau | 316L, 37Mn | ISO 9809-3, IS 8198 | Kūpaʻa i ka palaho Maʻemaʻe kiʻekiʻe |
Iāpana/Kōlea Hema: Ke koi nui ʻia nei ke kila metala kiʻekiʻe a maʻamau o JIS G3429 (STH11/STH22).
Mākeke Hikina Waena a me ʻApelika:
Nui ka makemake no ka ʻoihana aila a me ke kinoea, a kiʻekiʻe ka hiki ke loaʻa i ka mākeke lako mālama a me ka halihali CNG.
ʻO nā pono nui o nā paipu cylinder paipu kila seamless a Kina ma ka mākeke honua he hana kumukūʻai kiʻekiʻe, hoʻokō maʻamau, a me ke kaulahao lako paʻa.
Ma ke ʻano o nā kahawai kūʻai, hoʻopili pololei kā mākou hui me nā wili kila (e like me Kina Baosteel, Baotou Steel, Hengyang, Tianjin Steel Pipe) e loaʻa ai nā kumukūʻai haʻahaʻa.
Loaʻa ka maʻalahi kiʻekiʻe, ka lawelawe hoʻokahi no nā kauoha liʻiliʻi a me nā kauoha nui. No nā kauoha liʻiliʻi, e hāʻawi mākou i ka mea nui i ka loaʻa ʻana o kahi waihona, a no nā kauoha nui, e hana pū mākou me nā hale wili kila e hoʻolālā i ka hoʻonohonoho hana.
Hāʻawi mākou i nā kumukūʻai FOB a me CIF e kōkua i nā mea kūʻai aku e hoʻoponopono i nā logistics, ka hoʻomaʻemaʻe dute a me nā pilikia ʻē aʻe.
ʻOi aku ka liʻiliʻi o ke kumukūʻai o 34CrMo4 a me 37Mn i hana ʻia ma Kina ma mua o 20%-30% ma mua o nā huahana ʻEulopa. Hiki iā mākou ke hoʻolako paʻa i nā kauoha he nui. Loaʻa iā mākou nā mākaukau kūpono a me nā hiki ke hana no ka maʻa a me ka hāʻawi ʻana i nā kūlana. Loaʻa iā mākou nā mea hoʻouna ukana paʻa lōʻihi no nā ʻoihana ukana.
