1.Paipu kila welono ka lawe ʻana i ka wai haʻahaʻa haʻahaʻa (GB/T3092-1993) ua kapa ʻia ʻo ia nā paipu welded maʻamau, ʻike mau ʻia ʻo nā paipu ʻeleʻele.

He paipu kila welded no ka lawe ʻana i nā wai kaomi haʻahaʻa haʻahaʻa e like me ka wai, ke kinoea, ka ea, ka aila a me ka mahu mehana a me nā kumu ʻē aʻe. Hoʻokaʻawale ʻia nā paipu kila i nā paipu kila maʻamau a me nā paipu kila mānoanoa e like me ka mānoanoa o ka paia; e like me ke ʻano o nā wēlau paipu, ua hoʻokaʻawale ʻia lākou i nā paipu kila unthreaded (nā paipu maʻemaʻe) a me nā paipu kila. Hōʻike ʻia ka kikoʻī o ka paipu kila e ke anawaena nominal (mm), kahi kokoke i ke anawaena o loko. He mea maʻamau ka hōʻike ʻana i nā iniha, e like me 11/2. Ma waho aʻe o ka hoʻohana pololei ʻana i ka lawe ʻana i nā wai, hoʻohana nui ʻia nā paipu kila welded no ka lawe ʻana i ka wai haʻahaʻa haʻahaʻa e like me nā paipu kumu o nā paipu kila welded no ka lawe ʻana i ka wai haʻahaʻa.

2. Ua kapa ʻia ʻo Galvanized welded steel pipe no ka haʻahaʻa-press fluid transport (GB/T3091-1993) i kapa ʻia ʻo galvanized electric welded steel pipe, i ʻike ʻia he paipu keʻokeʻo.

ʻO nā paipu kila no ka lawe ʻana i ka wai, ke kinoea, ka aila ea, ka mahu mehana, ka wai mehana a me nā mea ʻē aʻe. Hoʻokaʻawale ʻia nā paipu kila i nā paipu kila galvanized maʻamau a me nā paipu kila galvanized mānoanoa e like me ka mānoanoa o ka paia; e like me ke ʻano o nā wēlau paipu, ua hoʻokaʻawale ʻia lākou i nā paipu kila galvanized non-threaded a me nā paipu kila galvanized. Hōʻike ʻia ka kikoʻī o ka paipu kila e ke anawaena nominal (mm), ʻo ia ka waiwai o ke anawaena o loko.

3. ʻO ka pahu kila kalapona maʻamau (GB3640-88) he paipu kila i hoʻohana ʻia no ka pale ʻana i nā uea i nā papahana hoʻonohonoho uila e like me nā hale ʻoihana a me nā hale kīwila, ka hoʻokomo ʻana i nā mīkini a me nā lako.

4. He paipu kila i hoʻopaʻa ʻia i ka hili pololei (YB242-63). Hoʻokaʻawale pinepine ʻia i ka metric uila welded steel paipu, uila welded thin-walled paipu, transformer cooling aila paipu a pēlā aku.

5.Piula kila i hoʻoheheʻe ʻia i loko o ke arcno ka lawe ʻana i ka wai kaomi (SY5036-83) i hana ʻia me nā wili kila ʻōwili wela e like me nā pahu hakahaka, hana pinepine ʻia i nā mahana wela, a welded ʻia e ka kuʻekuʻe ʻana i ʻelua ʻaoʻao submerged arc. Hoʻohana ʻia ia no ka lawe ʻana i ka wai kaomi. Paipu kila humuhumu wiliwili. Loaʻa i ka paipu kila ka mana hoʻoikaika ikaika a me ka hana wiliwili maikaʻi. Ma hope o nā ʻike ʻepekema koʻikoʻi a me nā hoʻāʻo, palekana a hilinaʻi hoʻi e hoʻohana. He nui ke anawaena o ka paipu kila, he kiʻekiʻe ka maikaʻi o ka lawe ʻana, a hiki ke mālama ʻia ka hoʻopukapuka ʻana i nā pipeline. Hoʻohana nui ʻia no nā pipelines no ka lawe ʻana i ka aila a me ke kinoea maoli.

6. Spiral seam kiʻekiʻe-frequency welded kila paipu no ka pressurized wai halihali (SY5038-83) ua hana ia me ka wela-wili kila wili e like me ka paipu blank, pinepine spirally hana i ka wela, a welded e kiʻekiʻe-frequency lap kuʻihao. Hoʻohana ʻia ia no ka lawe ʻana i ka wai kaomi. Piula kila kiʻekiʻe alapine wili wiliwili ʻia. Loaʻa i ka paipu kila ka mana paʻa ikaika a me ka plasticity maikaʻi, kahi kūpono no ka wili a me ka hana. Ma hope o nā hoʻokolohua koʻikoʻi a me ka ʻepekema, palekana a hilinaʻi hoʻi e hoʻohana. Hoʻohana nui ʻia no ka waiho ʻana i nā pipeline no ka lawe ʻana i ka aila, ke kinoea maoli, etc.

7. 'O ka mea ma'amau, ua hana 'ia ka pu'upu'u i ho'opa'a 'ia i loko o ke arc welded steel pipe (SY5037-83) no ka lawe 'ana i ka wai ha'aha'a me ke kila kila pumehana e like me ka pahu blank, i hana pinepine 'ia, a hana 'ia e ka 'akomi 'ao'ao 'elua. wiliwili arc submerged a i ʻole wiliwili ʻaoʻao hoʻokahi. ʻO nā paipu kila i hoʻoheheʻe ʻia i loko o ka pahu no ka lawe ʻana i ka wai e like me ka wai, ke kinoea, ka ea a me ka mahu.

8. Spiral seam kiʻekiʻe alapine welded kila paipu (SY5039-83) no ka maʻamau haʻahaʻa haʻahaʻa ka wai lawe mea i hana ia me ka wela-owili kila coil e like me ka paipu blank, pinepine spirally hana ma kiʻekiʻe wela, a welded e kiʻekiʻe-alapine lap kuʻihao. no ka lawe ʻana i ka wai haʻahaʻa haʻahaʻa. Seam kiʻekiʻe alapine welded paipu kila.

9. ʻO nā paipu kila wiliwili ʻia no nā puʻupuʻu (SY5040-83) i hana ʻia me nā wili kila wela e like me nā tube blanks, i hana pinepine ʻia e nā spiral mehana, a i hana ʻia me nā ʻaoʻao ʻelua ʻaoʻao submerged arc welding a kiʻekiʻe-frequency welding. Hoʻohana ʻia lākou no nā hale kūkulu kīwila, nā uapo, nā alahaka a me nā puʻu kumu ʻē aʻe me nā paipu kila.
