ʻO Q235B National Standard Spiral Steel Pipe he paipu kila wiliwili i hana ʻia mai ke kila wili ʻia ma o ka hoʻokuʻu ʻia ʻana o ka wela a me ka uea ʻelua -akomi, ʻaoʻao ʻelua{3}}ʻaoʻao arc i lalo. Hiki i kāna ka'ina hana ma'alahi ke hana i nā paipu -diameter nui, mānoanoa-pā, ho'ohana nui 'ia i ka ikehu, ka 'enekinia aupuni, a me nā 'oihana kemika.
Nā hiʻohiʻona huahana
Hana ʻia ʻo Q235B National Standard Spiral Steel Pip mai ke kaula kila ʻōwili ʻia, hoʻokuʻu ʻia ma ka lumi wela a wili ʻia me ka hoʻohana ʻana i ke kaʻina hana kuʻihao ʻauamo ʻelua ʻaoʻao, ʻaoʻao ʻelua{2}}. ʻO kona kūlana mua ʻo GB/T9711-1997, ʻo ia hoʻi me GB/T9711.1 (e hōʻike ana i ke kila Grade A) a me GB/T9711.2 (e hōʻike ana i ke kila Grade B). ʻO GB/T9711.2 ka mea maʻamau i ʻoi aku ka maikaʻi a me nā koi hoʻāʻo ma mua o GB/T9711.1 a kūpono ia no ka hoʻohana ʻana i ka lawe ʻana i nā wai wela, ʻaʻole no nā paipu hoʻolei.
Kaʻina Huahana
ʻOlokaʻa ʻia ke kaula kila ma o nā wili he nui i loko o kahi billet paipu spiral. Hoʻomalu ʻia ka ʻāpana weld ma 1-3mm. Hoʻohana ʻia ka ʻenehana welding arc submerged ʻaoʻao ʻelua e hōʻoia i ka maikaʻi o ka weld a hōʻemi i nā hemahema e like me ka misalignment a me ke komo ʻole ʻana.
Ma ka hoʻololi ʻana i ke kihi hana, hiki ke hana ʻia nā paipu me nā anawaena mai DN200 a DN3800. He akamai loa ka hui i ka hana ʻana i nā paipu paia liʻiliʻi a me waena -diameter mānoanoa-paipu paia.

Hebei Yugang Pipe Manufacturing Co., Ltd., me ISO9001, API 5L / 5CT / 5B palapala hōʻoia e like me kona pōhaku kihi, ua hoʻokumu i kahi ʻōnaehana hoʻomalu maikaʻi. Mai ke kūʻai pololei ʻana i nā mea waiwai mai ka wili kila a i ka hoʻoili ʻana i ka laina hana automated, e loaʻa i kēlā me kēia pūʻulu o nā huahana nā hoʻokolohua 23, me nā hoʻokolohua hydrostatic a me nā piko. Ua ho'okumu 'ia i ka makahiki 2005, ua ho'ololi ka hui i ka hui 'oihana a me ke kālepa i ka makahiki 2014 a ua lilo i 'oihana 'enehana ki'eki'e i ka makahiki 2024. I kēia manawa, ho'oki'eki'e ka hui i nā laina hana he 16, me nā paipu spiral, me ka loa'a makahiki he 300,000 tona. ʻO kā mākou laina huahana nui ka aila a me ke kinoea pipeline a me nā pono. Aloha mākou i nā nīnau a me nā nīnau!
Nā nīnau i nīnau pinepine ʻia (FAQ)
Q: He aha ka helu kauoha liʻiliʻi?
A: Hoʻololi ia ma muli o nā kikoʻī huahana, nā mea waiwai, a me ka pae o ka hana maʻamau. E ʻoluʻolu e hāʻawi i kāu mau koi kikoʻī a na mākou e hoʻoholo i ka hopena ʻoi aku ka waiwai no ʻoe.
Q: Pehea e hiki ai iaʻu ke loaʻa kahi ʻōlelo?
A: Hoʻopili ʻia nā kumukūʻai paipu kila e ka loli ʻana o nā mea maka, nā kikoʻī, ka hana, ka nui, a me nā kumu kūʻai. E ʻoluʻolu e kelepona i nā kūʻai aku ma ka leka uila a i ʻole kelepona a hāʻawi i kāu ʻike no kahi ʻōlelo pololei.
Q: He aha ke kaʻina hana a me ka manawa hāʻawi?
A: ʻO ka manawa hoʻouna e pili ana i ka nui o ke kauoha, ka paʻakikī kikoʻī, a me ka papa hana o kēia manawa. ʻOi aku ka wikiwiki o nā huahana maʻamau, ʻoiai ʻoi aku ka lōʻihi o nā kauoha nui a i ʻole nā hana maʻamau paʻakikī. E hōʻoia mākou i ka papa kuhikuhi kikoʻī me ʻoe ma mua o ke kau ʻana i kāu kauoha.
