Kaʻina hana

ʻO ke alapine kiʻekiʻepaipu wili wili pololei(ERW) maʻalahi ke kaʻina hana, hoʻokahi hana kikoʻī, me ka hoʻohana ʻana i ke kuʻi kūʻē a me ke kaʻina hana kuʻi kiʻekiʻe.Ua hoʻohana ʻia ka ʻenehana hana hoʻoheheʻe ʻia ʻo JCOE arc, hoʻoheheʻe ʻia ke kaʻina hana paʻakikī, kiʻekiʻe-frequency welded paipu ʻoi aku ka maikaʻi e pili ana i ke kumu kūʻai haʻahaʻa i ʻoi aku ka kiʻekiʻe ma mua o ke kiʻekiʻe o ke kiʻekiʻe kiʻekiʻe.

Ka lōʻihi

Pololei seam kila paipu me ka weld, ka weld lōʻihi a pōkole paha, akā, he pono ia he weld, e like me ka lōʻihi o ka pā, a i kēia manawa he aupuni kiʻekiʻe-frequency welded kila paipu welds hiki ke hana i 14 mika, papalua submerged arc. hiki ke hana i ke kuʻi ʻana i ka paipu kila wili pololei a hiki i 12.8 mika, nā kui welded kila pā ākea kaohi ma muli o ka weld hiki ke hana i ka 2.2 mika.

ʻIke ʻana

Hoʻokaʻawale ʻia ka hoʻāʻo ʻana o ka paipu kila pololei i loko o: ka haku mele, ka hoʻāʻo tensile, ka hoʻāʻo ʻana, ka hoʻāʻo hoʻopalapala, ka hoʻāʻo ʻana i ke kuʻekuʻe alakaʻi, ka hoʻāʻo hydraulic, ka hoʻāʻo ʻana i ke kani ultrasonic welded steel pipes, submerged arc welded pipe he ultrasonic testing, eddy current testing, ray detection hoao ana.Pono nā ʻili o loko a me waho o ka paipu kila, ʻaʻole i ʻae ʻia e pelu ʻia, nā māwae, ka delamination, ka uhaʻi ʻana, ka haki ʻana, ke ahi, a me nā hohonu ʻē aʻe ma mua o nā hemahema o ka mānoanoa o ka pā.ʻAʻole ʻoi aku ka hohonu ma mua o ka ʻae ʻia ʻana o nā hemahema kūloko hou.

Hoʻohana

Kiʻekiʻe alapine welded paipu hoʻohana no ka lawe ana i ka wai, kinoea, ea, aila a me ka mahu mehana, kūpono no ka haʻahaʻa puʻu wai paipu, structural steel.Hoʻohana ʻia i loko o Wangjiagongcheng, ka wai, nā paipu kinoea, ke kūkulu ʻana, ka ʻenekini uila, ka mīkini, nā kaola alahaka, ka hale kila, ka hoʻokumu ʻana o ke kahua a me nā mea hana ʻē aʻe.
