ʻO ka ʻokoʻa ma waena o nā paipu seamless a me nā paipu kila welded

1. Nā mea like ʻole:
* Paipu kila welded: ʻO ka paipu kila welded e pili ana i kahi paipu kila me nā hili o ka ʻili i hana ʻia ma ke kulou ʻana a me ka hoʻololi ʻana i nā ʻāpana kila a i ʻole nā ​​papa kila i loko o ka pōʻai, square, a i ʻole nā ​​ʻano ʻē aʻe, a laila wili. ʻO ka billet i hoʻohana ʻia no ka paipu kila welded ʻo ia ka pā kila a i ʻole ke kila kila.
*Pipu kila ʻole: He paipu kila i hana ʻia me ka ʻāpana metala me ka ʻole o nā hono ma ka ʻili, i kapa ʻia he paipu kila ʻole.

2. Hoʻohana like ʻole:
*Nā paipu kila welded: hiki ke hoʻohana ʻia e like me nā paipu wai a me ke kinoea, a ua hoʻohana ʻia nā paipu wili wili wili pololei nui-diameter no ka lawe ʻana i ka aila a me ke kinoea kiʻekiʻe; Hoʻohana ʻia nā paipu welded spiral no ka lawe ʻana i ka aila a me ke kinoea, nā paipu paipu, nā alahaka, etc.
* Paipu kila maʻemaʻe: hoʻohana ʻia no nā paipu hoʻoheheʻe ʻana i ka ʻaila ʻaila, nā paipu pohā no ka petrochemical, nā paipu paila, nā paipu halihali, a me nā paipu kila hoʻolālā kiʻekiʻe no nā kaʻa, nā trak, a me nā mokulele.

3. Hoʻokaʻawale ʻokoʻa:
* Nā paipu kila welded: E like me nā ʻano kuʻi ʻana like ʻole, hiki ke hoʻokaʻawale ʻia i nā paipu arc welded, kiʻekiʻe-frequency a haʻahaʻa-frequency resistance welded paipu, kinoea welded paipu, umu ahi welded paipu, Bondi paipu, etc. ua mahele hou ia i na paipu welded ma'amau, paipu welded galvanized, paipu welded oxygen puhi, lima lima, metric welded paipu, paipu wiliwili, paipu punawai hohonu, paipu kaa, paipu transformer, paipu paia lahilahi i wiliia, paipu ano kūikawā, a me na paipu wiliwili.
* Na paipu kila maʻemaʻe: Ua māhele ʻia nā paipu maʻemaʻe i loko o nā paipu wela, nā paipu anuanu, nā paipu huki anu, nā paipu extruded, nā paipu kiʻekiʻe, a me nā mea ʻē aʻe. a me ka pololei ole. He ʻano paʻakikī ko nā paipu maʻamau e like me ka huinahā, elliptical, triangular, hexagonal, hua melon, hōkū, a me nā paipu finned. ʻO ke anawaena kiʻekiʻe loa, a ʻo ka palena iki he 0.3mm. Wahi a nā kumu like ʻole, aia nā paipu pā mānoanoa a me nā paipu pā lahilahi.
