Wehewehe o Welded Steel Pipe Industry:

ʻO nā paipu kila welded, i kapa ʻia ʻo nā paipu welded, he mau paipu metala i hana ʻia ma o ke kaʻina hana. ʻO nā mea hoʻomaka e pili ana i nā ʻāpana kila a i ʻole nā ​​papa kila, i hoʻopiʻi ʻia a hana ʻia i nā ʻano like ʻole e like me ka poepoe, square, etc. I ke kaʻina hana, ʻo nā mea waiwai nui i hoʻohana ʻia he mau papa kila a i ʻole nā ​​ʻāpana kila, i koho maikaʻi ʻia a hoʻomākaukau ʻia no ka hana ʻana o nā ʻano paipu kila welded. Ma muli o ke ʻano o ka wili wili, hiki ke hoʻokaʻawale ʻia nā paipu welded i ʻelua ʻano nui: nā paipu wili wili pololei a me nā paipu wiliwili spiral.

Ma muli o ka wahi noi, hiki ke hoʻokaʻawale ʻia nā paipu kila welded i nā ʻano ʻano like ʻole, e like me ke kūpaʻa uila welded thin-wall paipu, uila kūpaʻa welded profile pipes, etc., kēlā me kēia optimized no kā lākou mau noi. Eia kekahi, ma muli o ke ʻano o ka welding i hoʻohana ʻia, hiki ke hoʻokaʻawale ʻia nā paipu welded i nā paipu welded gas, nā paipu welded umu, nā paipu bondi, etc.

ʻOihana Paipu kila Welded i luna, waena, a me lalo:

Ma ka ʻaoʻao o luna o ka ʻoihana paipu kila welded, ʻo nā mea maka mua e pili ana i nā ʻāpana kila wela, zinc ingots, a me nā mea hoʻoheheʻe, anti-corrosion coatings, etc. ʻO ka zinc ingots ma mua o 90%. E pili ana i nā noi i lalo, hoʻohana nui ʻia nā paipu kila welded i nā ʻoihana e like me ka petroleum, ke kinoea maoli, ka hoʻomehana, nā paipu wai wai, ke kūkulu ʻana, ka uila, a me nā mea ʻē aʻe. Hoʻohana pū ʻia lākou i ka hana ʻana i nā chassis kaʻa e hoʻonui i ka ikaika o nā kaʻa. Eia kekahi, ʻike nā paipu kila welded i ka noi i ka hana transformer, e hōʻoia ana i ka hana paʻa o nā ʻōnaehana mana.

I Iulai 2023, ʻike ʻia ka ulu ʻana o ka mahina o nā paipu kila welded ma Kina i ka ulu ʻana o ka makahiki.

ʻO ka mea kikoʻī, ʻo ka nui o ka hana ʻana o nā paipu kila welded i Iulai 2023 a hiki i 5.211 biliona tons, e hōʻailona ana i ka piʻi ʻana o 11.3% i hoʻohālikelike ʻia i ka manawa like i ka makahiki i hala. Ke nānā nei i ka hana kumulative mai ka hoʻomaka ʻana o ka makahiki a hiki i Iulai, ʻo ka hana hale o nā paipu kila welded he 35.079 miliona tons mai Ianuali a Iulai 2023, e hōʻike ana i ka ulu ʻana o ka makahiki ma ka makahiki o 13.1%. I kēia manawa, ke ulu wikiwiki nei ka ʻoihana paipu kila welded ma Kina, me nā hoʻokō koʻikoʻi i ka hoʻoponopono ʻana i ka ʻōnaehana huahana, hoʻomaikaʻi ʻana i ka ʻenehana, mālama i ka ikehu, a me ka emi ʻana o ka hoʻokuʻu. Me ka hoʻomau mau ʻana i ka ʻenehana welding a me ka maikaʻi, ke hoʻonui nei nā ʻano a me nā kikoʻī o nā paipu kila welded. Ke hoʻololi mālie nei lākou i nā paipu kila maʻemaʻe ma nā ʻano like ʻole, i kēia manawa ma kahi o 70% o ka nui o ka hana paipu kila.
