ʻO ka paipu ERW e pili ana i kahi ʻano kiʻekiʻe-frequency Electric Resistance Welding paipu kila. Hoʻokaʻawale ʻia ka paipu ERW i ʻelua mau ʻano o ka hoʻoheheʻe ʻana o AC a me DC, ʻo TUSPIPE ke kiʻekiʻe alapine wili i hoʻohana nui ʻia e hana i ka paipu kila mānoanoa me ka paia lahilahi a me ka mānoanoa, ʻo ka paipu ERW he hana holomua, alakaʻi i ka maikaʻi a me ka maikaʻi o ka paipu no ka aila a mālama kinoea a me ka lawe ʻana, a he mea kūpono ia no ka hapa nui o ka hana mīkini.
ʻO ka mea erw o ka paipu erw piha i ka huahana hope loa ma waena o ka paipu kila welded a me ka mea maʻemaʻe, a no ia mea, ʻoi aku ka maʻalahi a ʻoi aku ka paʻa o ka ʻili, no laila ʻaʻohe welds maopopo.
ʻAʻole i uhi ʻia ka ʻili o ka paipu kila ERW, ʻo ke kala he semi-smooth ʻeleʻele hina hina, a aia ka weld i loko.
Hoʻohana pinepine ʻia ka paipu ERW e like me ka casing uea i ka ʻoihana mana. ʻO nā hiʻohiʻona hana: 100% ka hoʻāʻo ʻana o ka ultrasonic o ka mea kumu e hōʻoia i ka maikaʻi o ke kino paipu; ʻaʻohe kaʻina ʻāwīwī-disc ʻoki ʻoki ʻana, ka lua metala kumu, nā ʻōpala liʻiliʻi; ʻaʻohe kumu koʻikoʻi i loko o ka paipu i hoʻopau ʻia ma hope o ka hoʻomaha ʻana i ke kaumaha; pōkole ka wili wili, a he liʻiliʻi ka nui o nā hemahema; Hiki ke lawe ʻia ke kinoea maoli ʻawaʻawa ma ke kūlana; ma hope o ka hoʻonui ʻana i ke anawaena, ʻoi aku ka kiʻekiʻe o ka nui geometric pololei o ka paipu kila; welding Ua lawe ʻia ia ma kahi laina pololei ma kahi kūlana ākea ma hope o ka pau ʻana o ka hana ʻana. No laila, ua hoʻomalu maikaʻi ʻia nā ʻaoʻao kuʻi, nā seams, a me ke anawaena paipu a me ke anapuni, a ʻoi aku ka maikaʻi o ka wili.
Hoʻokaʻawale ʻia nā huahana nui i ʻekolu mau ʻāpana: ʻelua laina laina laina laina laina laina, nā kikoʻī huahana 114.3mm-508mm, ka mānoanoa o ka pā 3.58mm-16.3mm. He ʻumi mau laina hana paipu spiral, nā kikoʻī huahana 219.1mm-3000mm, ka mānoanoa o ka paia 5mm-30mm. ʻElua laina hana no ka ʻaila hinu kūikawā, nā kikoʻī huahana 60.32mm-508mm, ka mānoanoa o ka pā 4.24mm-16.3mm. Hoʻolako ʻia me nā laina hana anti-corrosion a me ka insulation. ʻO ka puka makahiki o nā paipu kila a hiki i 500,000 tons. Hiki i nā huahana ke hoʻokō i nā kūlana: API 5L, API 5CT, ASTM, EN10219-2, GB/T9711, 3091-20081, 3793-2008, 14291-2006 a me nā kūlana honua hou loa. Loaʻa nā helu kila huahana: GRB, X42, X52, X60, X65, X70, J55, K55, N80, L80, P110, etc. Hoʻohana nui ʻia nā huahana i ka aila, ke kinoea maoli, ke kinoea, nā mines lanahu, mīkini, uila, pilang a nā kumu ʻē aʻe.
