No ka manawa lōʻihi, he kūlana maikaʻi loa ʻo Tianjin i ka ʻoihana paipu kila ma ka honua. Me nā makahiki o ka hana ʻana a me ka ʻike hana ʻana, ʻoi aku ka maikaʻi a me ka oʻo ʻana o Tianjin welded steel pipe production technology i kēia lā. ʻO kekahi mau ʻāpana hollow he mau kihi pōʻai ʻoi aku ka maikaʻi o ka pale ʻana ma mua o kēlā me nā kihi ʻoi. He ʻoiaʻiʻo loa kēia no nā ʻāpana i nā ʻāpana ʻāpana pōʻai kahi e hoʻololi mālie ai mai kekahi ʻāpana a i kekahi. I kēia manawa, hoʻonui kēia palekana maikaʻi i ka wā pale o nā pale mai ka corrosion.
I nā makahiki i hala iho nei, me ka hoʻokō ʻana i ka hoʻolālā aupuni "e hele i waho" a me ka hoʻokele waiwai honua honua, ʻo Tianjin welded steel paipu ke komo ikaika nei i ka mākeke honua a ua pāʻani i kahi hana koʻikoʻi i ke kālepa ʻoihana honua. I ka mākeke paipu kila o kēia manawa, hiki ke hoʻokaʻawale ʻia ʻo Tianjin welded steel pipe i ka paipu wili wili pololei a me ka paipu wiliwili spiral e like me nā ʻano like ʻole o ka paipu kila welded. I kēia lā, ua hoʻohana nui ʻia nā paipu kila welded e like me kekahi o nā mea hale koʻikoʻi i nā hana kūkulu. ʻO Tianjin welded steel tube he hōʻoia maikaʻi maikaʻi loa, a he ʻano kikoʻī hoʻi o nā kikoʻī, hiki ke hoʻokō pono i nā pono o nā ʻano āpau o ke ola no nā kumu noi kūpono.
I kēia lā, ua lilo ʻo Tianjin welded steel pipe i mea nui o ka hana a me ke ola o nā kānaka. Me ka hoʻonui houʻana o ka hoʻokele waiwai pilikanaka, ua ulu aʻe ka nui o nā mea hana paipu kila hou e loaʻa i ka ulu wikiwiki i kaʻoihana kila. ʻO Tianjin DaQiuzhuang, he kumu hoʻokumu ʻia ʻo welded steel pipe production base kahi e hiki ai iā ʻoe ke ʻike i kāu mau paipu kila wili maikaʻi me ka hoʻomanawanui a me ka laki. I kēia mau makahiki i hala iho nei, ʻo ka mākeke kalepa ʻē aʻe e pili ana i ka nui o ka hoʻomohala ʻana, kahi e hālāwai ai nā mea hana paipu kila Tianjin i nā manawa like ʻole a me nā pilikia i manaʻo ʻole ʻia i kēia manawa a laila. Ma ia mea, he mea koʻikoʻi loa ka nānā ʻana o nā ʻoihana kila i ka mākeke kālepa haole i ka wā lōʻihi.
E pili ana i nā kumukūʻai paipu kila, ua manaʻo ʻia e hana i kahi kālā kūpono no nā kumukūʻai kūʻai. Ma kahi ʻano, e kōkua kēia iā mākou e pale i nā ʻano makapō āpau i ke kūʻai ʻana, a me ka hoʻonui ʻana i ka mālama kālā, i mea e kūʻai hope ai i nā huahana kūpono. Tianjin galvanized kila paipu maʻamau loaʻa ke kumu kūʻai kūpono i ka mākeke. Ma muli o kona lōʻihi a me nā waiwai anti-corrosive, hiki ke hana hou a hoʻohana hou ʻia ka paipu kila galvanized, kahi e mālama ai i ke kālā he nui i ka wā o ka hana mālama post.
E hoʻouna i kāu leka iā mākou:
