ʻenehana Weld Tube ʻOihana

Kiʻi Hōʻikeʻike ʻia ʻo Tube Weld Technology

ʻO ka wehewehe pōkole:

Aia ma mua o kēia mea hou kā mākou ʻenehana Submerged Arc Welding (SAW), ke ʻano i makemake ʻia no ka paipu spirally welded. Hoʻomaopopo kēia ʻenehana i ka pololei, ka lōʻihi a me ka maikaʻi, e kūpono ana ia no nā ʻoihana e hilinaʻi nei i ka paipu welded kiʻekiʻe.

Pōmaikaʻi Hui

Aia i loko o ka puʻuwai o Cangzhou City, Hebei Province, he alakaʻi ka hui i ka hana paipu welded mai kona hoʻokumu ʻia ʻana i ka makahiki 1993. Ua uhi ka mea kanu i kahi ʻāpana o 350,000 square meters a ua hoʻolako ʻia me nā mīkini kiʻekiʻe a me ka ʻenehana e hana i nā huahana papa mua e kū ana i nā kūlana honua. Me ka nui o ka waiwai o RMB 680 miliona a me 680 mau limahana akamai, ua kūpaʻa ka hui i ka maikaʻi ma nā ʻano āpau o kāna hana.

Hoʻolauna Huahana

Ke hoʻolauna nei i kā mākou ʻenehana hoʻoheheʻe paipu kūikawā kiʻekiʻe loa, i hoʻolālā ʻia e hoʻokō i nā koi koi o ka arc welding natural gas pipelines. Aia ma mua o kēia mea hou kā mākou ʻenehana Submerged Arc Welding (SAW), ke ʻano i makemake ʻia no ka paipu spirally welded. Hoʻomaopopo kēia ʻenehana i ka pololei, ka lōʻihi a me ka maikaʻi, e kūpono ana ia no nā ʻoihana e hilinaʻi nei i ka paipu welded kiʻekiʻe.

ʻO kā mākou mea kūikawāwili paipuʻAʻole hoʻomaikaʻi wale ka ʻenehana i ka paʻa o nā pipeline kinoea, hoʻomaikaʻi pū i ke kaʻina hana kuʻi, hoʻopōkole i ka manawa hana a hoʻemi i nā kumukūʻai. Hoʻomaopopo mākou i ke koʻikoʻi o nā ʻōnaehana pipeline gas, a ʻo kā mākou kūpaʻa i ka maikaʻi e hōʻoia i ka hiki i kā mākou huahana ke kū i nā koi koʻikoʻi o kā lākou mau noi i manaʻo ʻia.

Ke hoʻomau nei mākou i ka hana hou a hoʻomaikaʻi i ka ʻenehana welding, kono mākou iā ʻoe e ʻike i ka hilinaʻi a me ka hana ʻana o kā mākou ʻenehana wili paipu ʻoihana. E hilinaʻi iā mākou e hāʻawi iā ʻoe i ka paipu welded kiʻekiʻe kiʻekiʻe e kū ana i kāu mau pono kikoʻī, i kākoʻo ʻia e nā makahiki o ka ʻike a me ka hoʻokō ʻana i ka ʻoluʻolu o ka mea kūʻai aku.

FAQ

Q1. He aha ka Submerged Arc Welding (SAW)?

ʻO SAW kahi kaʻina hana wili e hoʻohana ai i ka electrode hānai mau a me kahi papa o ka flux fusible granular e pale ai i ka weld mai ka haumia. He kūpono kēia ʻano hana i nā mea mānoanoa a kūpono hoʻi no nā paipu kinoea kūlohelohe.

Q2. No ke aha i makemake ʻia ai ʻo SAW no nā paipu welded spiral?

Hāʻawi ka ʻenehana SAW i ke komo hohonu a me ka ʻili maʻemaʻe, ka mea koʻikoʻi i ka kūpaʻa o ka halepaipu wiliwili spiralhoʻohana ʻia i nā noi kiʻekiʻe e like me ka lawe ʻana i ke kinoea kūlohelohe.

Q3. He aha nā pōmaikaʻi o ka hoʻohana ʻana i ka ʻenehana wili paipu ʻoihana?

ʻO nā ʻenehana hoʻoheheʻe paipu kūikawā e hōʻoia i ka maikaʻi mau, e hōʻemi i ka hopena o nā hemahema a hoʻomaikaʻi i ka hana holoʻokoʻa o nā huahana welded, he mea nui ia i kahi ʻoihana palekana.

Q4. Pehea e hōʻoia ai kāu ʻoihana i ka maikaʻi o ke kaʻina hana welding?

Hoʻopili kā mākou hui i nā ʻano hoʻomalu maikaʻi a hoʻohana i nā ʻenehana loea i hoʻomaʻamaʻa ʻia i nā ʻenehana welding hou loa, me ka SAW, e hōʻoia i kēlā me kēia huahana e hoʻokō i nā kūlana palekana a me ka hana.
