Hana ʻia ka paipu kila maʻemaʻe ma ka hoʻoheheʻe ʻana i ke kila poepoe holoʻokoʻa, a ʻo ka paipu kila me ka ʻole o ka weld seam ma luna o ka ʻili i kapa ʻia ʻo seamless steel pipe. E like me ke kaʻina hana, hiki ke hoʻokaʻawale i nā paipu kila maʻemaʻe i loko o nā paipu kila hoʻoheheʻe wela, nā paipu kila liʻiliʻi i ʻōwili ʻia, nā paipu kila liʻiliʻi i huki ʻia, nā paipu kila ʻole i hoʻokuʻu ʻia, a me nā paipu jacking. Wahi a ke ʻano cross-sectional, ua hoʻokaʻawale ʻia nā paipu kila seamless i ʻelua ʻano: poepoe a me ke ʻano kūikawā, a ʻo nā ʻano ʻano kūikawā he mau ʻano paʻakikī like ʻole e like me ka square, oval, triangular, hexagonal, melon-shaped, star-shaped, a me na paipu hope. ʻO ke anawaena kiʻekiʻe a hiki i 900mm a ʻo ka palena iki he 4mm. E like me nā hoʻohana ʻokoʻa, aia nā paipu kila maʻemaʻe ʻole i ka paia a me nā paipu kila maʻemaʻe ʻole. Hoʻohana nui ʻia nā paipu kila maʻemaʻe e like me nā paipu hoʻoheheʻe ʻana i ka aila, nā paipu haki no ka ʻoihana petrochemical, nā paipu paila, nā paipu halihali, a me nā paipu kila kila kiʻekiʻe no nā kaʻa, tractors, a me nā mokulele.

He paipu kila ma ka ʻaoʻao o kona ʻāpana kea. E like me nā ʻano hana like ʻole, ua māhele ʻia i loko o ka paipu wela, ka paipu anu, ka paipu anu, ka paipu extruded, ka paipu jacking, a me nā mea ʻē aʻe.

Loaʻa nā mea hana maʻamau a me ke kiʻekiʻe kiʻekiʻe o ka carbon structural steel, haʻahaʻa haʻahaʻa kila, alloy steel, etc.

Wahi a ke kumu, ua māhele ʻia i ʻelua mau ʻāpana: kumu maʻamau (no ka wai, nā pipeline gas a me nā ʻāpana structural, nā ʻāpana mechanical) a me ke kumu kūikawā (no nā boilers, geological exploration, bearings, acid resistance, etc.).

ʻOi aku ka nui o ke anawaena o waho o ka paipu wela ʻole ma mua o 32mm, a ʻo ka mānoanoa o ka pā he 2.5-200mm. ʻO ke anawaena o waho o ka paipu kila liʻiliʻi i ʻōwili ʻia e hiki ke hiki i 6mm, a hiki i ka mānoanoa o ka paia ke hiki i 0.25mm. ʻOi aku ka pololei o ka ʻōwili ʻana ma mua o ka ʻōwili wela. ʻO ka mea maʻamau, hana ʻia nā paipu kila maʻemaʻe o 10, 20, etc., nā kila kila kila.P5, P9, P11, P22, P91, P92, 15mog, 20mog, 12crmog, 15crmog, 12cr2mog, 12crmovg, etc. o.10, 20a me nā mea ʻē aʻehaʻahaʻa kalapona kila seamless paipuHoʻohana nui ʻia no nā pipeline lawe wai. ʻO ka maʻamau, hoʻohana ʻia nā paipu kila ʻole e hōʻoia i ka ikaika a me nā hoʻāʻo palahalaha. Hāʻawiʻia nā paipu kila wela i loko o kahi kūlana wela a wela paha; Hāʻawiʻia nā paipu kila i'ōwiliʻia ma kahi kūlana wela.
