ʻO ka paipu kila nona ke anawaena o waho a me ka mānoanoa o ka pā ma lalo o 20, ua kapa ʻia ʻo ia ka paipu kila mānoanoa.

Hoʻohana nui ʻia e like me ka petroleum geological drilling pipes, cracking pipes for petrochemical industry, boiler pipes, bearing pipes and high-precision structural pipes for automobiles, tractors, and aviation.

Kaʻina hana o ka paipu kila ʻole

1. ʻO ka'ōwili wela (extruded seamless steel pipe): pōʻai paipu billet → hoʻomehana → piercing → ʻekolu ʻōwili keʻa, ʻōwili mau a extrusion → hoʻoneʻe paipu → hoʻonui ʻia (a hōʻemi paha) → hoʻomaʻamaʻa → Straightening → hoʻāʻo hydraulic (a ʻike hewa paha) → hōʻailona → hale kūʻai.

ʻO ka mea maka no ka ʻōwili ʻana i nā paipu liʻiliʻi he billet paipu poepoe, ʻoki ʻia nā pila paipu pōʻai e ka mīkini ʻoki i loko o kahi billet me ka lōʻihi o 1 mika a hoʻouna ʻia i ka umu no ka hoʻomehana ʻana ma o ke kāʻei conveyor. Hāʻawi ʻia ka billet i loko o ka umu ahi a hoʻomehana ʻia ma kahi mahana o 1200 degere Celsius. He hydrogen a acetylene ka wahie. ʻO ka hoʻomalu ʻana i ka mahana i loko o ka umu ahi kahi mea nui. Ma hope o ka puka ʻana o ka paipu poepoe i waho o ka umu, pono e hou ʻia i ka mīkini kuʻi kaomi. ʻO ka mea maʻamau, ʻo ka mīkini ʻīwī maʻamau ʻo ia ka mīkini piercing tapered roller. ʻO kēia ʻano mīkini piercing he kiʻekiʻe ka hana hana, maikaʻi ka huahana maikaʻi, hoʻonui nui perforation diameter, a hiki ke komo i nā ʻano kila like ʻole. Ma hope o ka hou ʻana, ʻolokaʻi ʻia ka billet paipu poepoe, ʻōwili mau ʻia a hoʻopau ʻia paha e nā ʻōwili ʻekolu. Ma hope o ka ʻomi ʻana, wehe i ka paipu a hoʻopaʻa. Holoi ka mīkini nui i ka wikiwiki nui ma o ka conical drill bit e wili ai i nā lua i loko o ke kila blank e hana i ka paipu kila. Hoʻoholo ʻia ke anawaena o loko o ka paipu kila e ka lōʻihi o ke anawaena o waho o ka drill bit o ka mīkini sizing. Ma hope o ka nui o ka paipu kila, komo ia i loko o ka hale hoʻomaha a hoʻomaʻalili ʻia e ka wai. Ma hope o ka maʻalili ʻana o ka paipu kila, e hoʻopololei ʻia. Ma hope o ka hoʻopololei ʻana, hoʻouna ʻia ka paipu kila i ka mea ʻike kīnā metala (a i ʻole hydraulic test) e ke kāʻei conveyor no ka ʻike hewa o loko. Inā loaʻa nā māwae, ʻōhū, a pēlā aku i loko o ka paipu kila, e ʻike ʻia. Ma hope o ka nānā ʻana i ka maikaʻi o nā paipu kila, pono ke koho lima paʻa. Ma hope o ka nānā ʻana i ka maikaʻi o ka paipu kila, e pena i ka helu serial, kikoʻī, helu pūʻulu hana, etc. me ka pena. Hoʻokuʻu ʻia i loko o ka hale waihona kālā e kahi crane.

2.Cold drawn (rolled) seamless steel pipe: round tube billet → heat → piercing → heading → annealing → pickling → oiling (copper plating) → multi-pass anu kiʻi (cold rolling) → billet tube → wela → straightening → wai Compression ho'āʻo (flaw detection) → hōʻailona.→ → hōʻailona.

Hoʻokaʻawale ʻana i ka hoʻohua ʻana o ka paipu maʻemaʻe - paipu ʻōwili wela, paipu ʻōwili anu, paipu huki anu, paipu hoʻokuʻu ʻia, paipu paipu.

9. ʻO ka paipu hoʻoheheʻe ʻaila (YB528-65) he paipu kila maʻemaʻe ʻole i hoʻohana ʻia no ka mānoanoa o loko a i waho paha ma nā ʻaoʻao ʻelua o ka ʻaila ʻaila. Hoʻokaʻawale ʻia nā paipu kila i ʻelua ʻano: uea a me ka ʻole. Hoʻopili ʻia nā paipu uea e nā hono, a ʻo nā paipu uea ʻole i hoʻopili ʻia me nā mea paahana e ka wili ʻana.

10. ʻO nā paipu kila maʻemaʻeʻole no nā moku (GB5213-85) he mau paipu kila maʻemaʻeʻole i hoʻohanaʻia i ka hanaʻana i nā'ōnaehana paipu puʻupuʻu Class I, Class II pressure pipe system, boilers a superheaters. ʻAʻole ʻoi aku ka mahana o ka pā o ka pā paipu kila kila ma mua o 450 ℃, ʻoiai ʻo ka pā o ke kila kila ma mua o 450 ℃.

11. ʻO nā paipu kila maʻemaʻe ʻole no nā lima axle kaʻa (GB3088-82) he kiʻekiʻe kiʻekiʻe ka carbon structural steel a me ka hoʻoheheʻe ʻana i ke kila kila wela-wili ʻia no ka hana ʻana i nā lima axle kaʻa a me nā paipu axle axle.

12. ʻO nā paipu aila kiʻekiʻe no nā ʻenekini diesel (GB3093-86) he mau paipu kila maʻemaʻe ʻole i huki ʻia i ke anu i hoʻohana ʻia no ka hana ʻana i nā paipu kiʻekiʻe no nā ʻōnaehana injection engine diesel.

13. ʻO nā paipu kila maʻemaʻe ʻole ke anawaena o loko no ka hydraulic a me ka pneumatic cylinders (GB8713-88) he mau paipu kila liʻiliʻi a i ʻole ka ʻōwili anuanu me nā anawaena kūpono o loko no ka hana ʻana i nā cylinders hydraulic a pneumatic.

14. ʻO ke anu a i ʻole ke anu a i ʻole ka hoʻoheheʻe ʻia ʻana o ka paipu kila liʻiliʻi (GB3639-83) he paipu kila liʻiliʻi a i ʻole ke anu me ka pololei kiʻekiʻe a me ka hoʻopau ʻana i ka ʻili maikaʻi no ka hana mechanical a me nā lako hydraulic. ʻO ka hoʻohana ʻana i nā paipu kila maʻemaʻe ʻole e hana i nā hale mechanical a i ʻole nā ​​​​mea hana hydraulic hiki ke hoʻopakele nui i ka mīkini hana kanaka-hola, hoʻonui i ka hoʻohana waiwai, a ma ka manawa like e kōkua i ka hoʻomaikaʻi ʻana i ka maikaʻi o ka huahana.

15. ʻO ke kila kuhiliʻole i hoʻopaʻa ʻia (GB / T14975-1994) he kila kila wela i hana ʻia me nā paipu kūpaʻa i ka corrosion a me nā ʻāpana a me nā ʻāpana i hoʻohana nui ʻia i ka kemika, ka ʻaila, ka textile, nā lāʻau lapaʻau, nā meaʻai, nā mīkini a me nā ʻoihana ʻē aʻe (Extruded, expanded) a me ke kila huki ʻia (rolled).

16. ʻO nā paipu kila maʻemaʻeʻole no ka laweʻana i ka wai (GB / T14976-1994) i'ōwili wela (extruded, hoʻonui) a me nā paipu kila liʻiliʻi i hukiʻia (rolled) i hanaʻia me ke kila kila no ka laweʻana i ka wai.

17. He hua'ōlelo maʻamau no nā paipu kila maʻemaʻe ʻole me nā ʻano ʻāpana keʻa ma waho o nā paipu poepoe. E like me ke ano okoa a me ka nui o ka pauku paipu kila, hiki ke maheleia i like-walled special-shaped seamless steel pipe (code D), unequal-walled special-shaped seamless steel pipe (code BD), a me ka anawaena hoololi kūikawā-like seamless kila paipu (code BJ). Hoʻohana nui ʻia nā paipu kila maʻemaʻe kūikawā i nā ʻāpana like ʻole, nā mea hana a me nā ʻāpana mechanical. Ke hoʻohālikelike ʻia me nā paipu poepoe, ʻoi aku ka nui o nā manawa o ka inertia a me ka modulus pauku o nā paipu kūikawā, a ʻoi aku ka nui o ke kūlou ʻana a me ke kūpaʻa ʻana, hiki ke hōʻemi nui i ke kaumaha o ke kino a mālama i ke kila.

ʻO ka mea maʻamau, hana ʻia nā paipu kila maʻemaʻe o 10, 20, 30, 35, 45 a me nā kila kalapona kiʻekiʻe ʻē aʻe e like me 16Mn, 5MnV a me nā mea hao haʻahaʻa haʻahaʻa haʻahaʻa a i ʻole 40Cr, 30CrMnSi, 45Mn2, 40MnB a me nā ʻōwili wela ʻē aʻe. ʻO nā paipu seamless i hana ʻia me ke kila kalapona haʻahaʻa e like me 10 a me 20 e hoʻohana nui ʻia no nā pipeline lawe wai. Hoʻohana ʻia nā paipu seamless i hana ʻia me ke kila kalapona maʻamau e like me 45 a me 40Cr e hana i nā ʻāpana mechanical, e like me nā ʻāpana koʻikoʻi o nā kaʻa a me nā tractors.　ʻO ka maʻamau, pono e hoʻohana ʻia nā paipu kila ʻole no ka ikaika a me ka hoʻāʻo palahalaha. Hāʻawiʻia nā paipu kila wela i ka moku wela a iʻole ka wela wela; hāʻawi ʻia nā paipu kila i ʻōwili ʻia i ka wela wela. ʻO nā paipu kila maʻemaʻe no nā paila haʻahaʻa a me waena: hoʻohana ʻia no ka hana ʻana i nā paila haʻahaʻa haʻahaʻa a me waena, ʻo nā paipu mokumahu wela, nā paipu wai paila, nā paipu wai paia a me nā paipu mahu no nā locomotive boilers, nā puʻupuʻu uahi nui, nā paipu uwahi liʻiliʻi a me nā paipu brick arched.

　　E hoʻohana i ke kila kila kila wela a i ʻole ke anu (dial) paipu kila ʻole. Ua hana nui ia me ka No. 10 a me ka No. 20 kila. Ma waho aʻe o ka hōʻoia ʻana i ka hoʻohui kemika a me nā waiwai mechanical, pono e hana ʻia kahi hoʻāʻo hydraulic, e like me ka crimping, flaring, a me ka palahalaha. Hāʻawiʻia nā huahana i hoʻopiliʻia i ka wela wela, aʻo nā mea i hoʻopiliʻia i ke anuanu e hāʻawiʻia i kahi kūlana wela.

18.GB18248-2000 (Seamless steel pipe no gas cylinders) ua hoʻohana nuiʻia e hana i nā kinoea likeʻole a me ka hydraulic cylinders. ʻO kāna mau mea kikoʻī he 37Mn, 34Mn2V, 35CrMo, etc.

E ʻike i nā paipu kila mānoanoa a haʻahaʻa

1. He maʻalahi ke pelu ʻana i nā paipu kila mānoanoa me ka mānoanoa.
