Ma ke ʻano he mea hana alakaʻi ma kēia kahua,ʻO Cangzhou Spiral Steel Pipe Group Co., Ltd.hoʻopili pono i nā kūlana honua a loea i ka hana ʻana o ka electrofusion arc weldednā paipu kila humuhumu ʻōwilie uhi ana i ʻelima mau papa. ʻO kēia ʻano oPaipu kila ASTMua hoʻolālā kūikawā ʻia no ka lawe ʻana i nā wai, nā kinoea a i ʻole ka mahu, e hōʻoiaʻiʻo ana i ka hana palekana a me ka pono ma nā ʻano kaomi kiʻekiʻe a me nā wahi paʻakikī.
ʻO ka ikaika o ka ʻoihana mai kona hiki ke hana nui a holomua. Loaʻa iā mākou he 13 mau laina hana paipu kila wili a me 4 mau laina hana anti-corrosion a me ka thermal insulation, hiki ke hana i nā paipu kila wili me nā anawaena waho mai 219 millimeters a 3500 millimeters a me nā mānoanoa o ka paia a hiki i 25.4 millimeters.
ʻAʻole wale nā huahana hōʻailona "Wuzhou" e kūlike me nā kūlana honua he nui e like me API Spec 5L a me EN 10219, akā ua hoʻokō piha hoʻi i nā koi o nā kūlana koʻikoʻi e like me ASTM A139 a me ASTM A252.
He ākea loa nā hiʻohiʻona noi o kēia mau paipu kila Kina e kūlike ana me nā kūlana ASTM. Ua hoʻopili pono ʻia lākou i nā papahana koʻikoʻi e like me ka lako wai kūlanakauhale a me nā pūnaewele hoʻokahe wai, ka halihali kinoea kūlohelohe a me ka ʻaila mamao loa, a me nā ʻōnaehana paila paipu, e hāʻawi ana i nā "kīʻaha koko" paʻa a paʻa no ke kūkulu ʻana i nā ʻoihana honua.
ʻO ke koho ʻana i kahi mea hana me nā palapala hōʻoia hōʻoia honua ka hana mua i ka hōʻoia ʻana i ka hilinaʻi lōʻihi o nā papahana pipeline. ʻO Cangzhou Spiral Steel Pipe Group, me kona mālama pono ʻana i nā kūlana ASTM a me ka mana hana i hana ʻia maʻamau, hāʻawi i nā mea kūʻai aku me nā hopena hoʻokahi mai ka hana ʻana a i ka anti-corrosion.
No ka ʻike hou aku e pili ana i nā kikoʻī, nā kikoʻī hōʻoia a me nā hiki ke hoʻopilikino ʻia o kā mākou mau paipu kila wili kūlike ASTM, e ʻoluʻolu e kelepona i kā mākou hui ʻoihana no ke kūkākūkā loea kikoʻī a me nā ʻōlelo kikoʻī.
