201 202 310S 304 316 Mea hoʻolalelale ʻia i hoʻopaʻa ʻia i hoʻopaʻa ʻia.
Ka hoʻokaʻawale ʻana o nā paipu kaula:
ʻO NPT, PT, a me G nā kaula paipu.ʻO ka NPT he 60° taper pipe thread i pili i ke kūlana ʻAmelika a hoʻohana ʻia ma ʻAmelika ʻĀkau.Hiki ke loaʻa nā kūlana aupuni ma GB/T12716-2002m.
ʻO ka PT he 55 ° i hoʻopaʻa ʻia i ke kaula paipu tapered, ʻo ia ke ʻano o ke kaula Wyeth a hoʻohana nui ʻia ma nā ʻāina ʻEulopa.ʻO ka liʻiliʻi he 1:16.Hiki ke loaʻa nā kūlana aupuni ma GB/T7306-2000.(Hoʻohana nui ʻia i ka wela kiʻekiʻe, nā ʻōnaehana kiʻekiʻe a me nā ʻōnaehana lubrication)
ʻO G he 55° non-thread sealing pipe thread, ʻo ia ke ʻano o ke kaula Wyeth.Hōʻailona ʻia ʻo G no ke kaula cylindrical.Hiki ke loaʻa nā kūlana aupuni ma GB/T7307-2001 (hoʻohana nui ʻia no nā paipu wai a me ke kinoea me ke kaomi ma lalo o 1.57MPa).ʻO G ka inoa nui o ke kaula paipu, i ʻike mau ʻia ʻo ka pōʻai paipu.ʻO ia hoʻi, ua hana ʻia ke kaula e ka ʻili cylindrical.ʻO ZG ka mea maʻamau i kapa ʻia ʻo ka paipu cone, ʻo ia hoʻi, ua hana ʻia ka milo e ka ʻili conical, a ua kaha ʻia ke kūlana aupuni ʻo Rc (cone inner pipe thread).ʻO ke kaula G a me ke kaula Rp he 55° nā lola paipu cylindrical.ʻO Rp ka inoa code o ISO.
ʻO ka hapa GB o ka maʻamau o Kina e like me ka ISO maʻamau honua.ʻO nā kikoʻī penei:
1. ʻO ke kūpono o ka milo loko cylindrical (Rp) a me ke kaula waho tapered (R1), i kapa ʻia ʻo "column/cone fit", ka helu maʻamau o koʻu ʻāina GB/T7306.1-2000, e like me ka hoʻokō ʻana i ke kūlana honua ISO7-1 : ʻO ka "column/cone fit" i ka makahiki 1994 "pipe thread i sila ʻia me ka milo";
2. ʻO ke kūpono o ke kaula i loko (Rc) a me ke kaula waho waho (R2), i kapa ʻia ʻo "cone/cone fit", ʻo ka helu maʻamau o kā mākou ʻāina ʻo GB / T7306.2-2000, kahi e hoʻokō like ai i ke kūlana honua ISO7- 1 ： ʻO ka "cone/cone fit" i ka makahiki 1999 "pipe thread i sila ʻia me ka milo";
3. ʻO ke kūpono o ke kaula i loko o ka cylindrical (G) a me ke kaula waho cylindrical (G) i kapa ʻia ʻo "column / column fit".ʻO ka helu maʻamau o ko mākou ʻāina ʻo GB / T7307-2001 "55 ° non-sealed pipe thread".Ua like kēia maʻamau ʻO ka hapa mua o ka pae honua ISO228-1: 1994 "Non-thread-sealed pipe threads" he "Dimensional tolerances and markings", akā ʻaʻole ʻōlelo nā kūlana o koʻu ʻāina i ka hoʻohana ʻana i nā kaula paipa i hoʻopaʻa ʻia a me nā kaula paipu i hoʻopaʻa ʻole ʻia. , ʻo ia hoʻi (Rp /G);
1. ʻO ka wai anuanu a me nā ʻōnaehana hoʻoheheʻe wai e hoʻopili i ka pilina pili i ka wā i emi ai ke anawaena paipu ma mua o 50mm.
2. Hoʻohana ʻia ka mīkini hoʻoheheʻe paipu no ka hoʻoili ʻana i ka milo a hoʻohana ʻia ka ʻaila mīkini ʻenehana kūikawā no ka lubrication.ʻAʻole ʻae ʻia ka wai a me nā wai ʻē aʻe e pani i ka lubricant.
3. Hoʻohana ʻia ka aila alakaʻi a me ka uea hemp no ka hoʻopaʻa ʻana i ka pipeline a me ka hoʻopili ʻana, a hoʻohana ʻia ka lipine Teflon no ka hoʻopili ʻana me nā mea hana.ʻAʻole ʻae ʻia ka lawe ʻana i ka paʻi i loko o ka paipu ke hoʻopaʻa ʻia ke kaula.
4. Pono e hana ʻia ka ʻoki ʻana i ka paipu me ka ʻoki a i ʻole ka hacksaw.ʻAʻole ʻae ʻia ka oxygen acetylene a i ʻole ka mīkini ʻoki.ʻAʻole ʻoi aku ka nui o ka ʻae ʻana o ka maka hope o ka ʻoki ma mua o 1% o ke anawaena o waho o ka paipu, a ʻaʻole pono ma mua o 3mm.
5. I mea e hōʻoia ai i ka liʻiliʻi liʻiliʻi o ka mānoanoa o ke aʻa wili, pono ke kau ʻia ma luna o ka pōʻai i loko o ka ʻili hope o ka ʻāpana paipu, a pono e hoʻomalu pono ʻia ka axial thread deviation a me ke axial tilt o ke kaula paipu, no ka mea. inā he axial parallel deviation a i ʻole axial tilt deviation, ʻelua e hoʻemi nui i ka mānoanoa o ka pā paipu, a laila e hōʻemi i ka ikaika o ka paipu.
ʻAe ʻia ka hoʻokaʻawale ʻana o ka hana ʻana i ke kaula paipu
ʻO ke anawaena inoa (mm) Hoʻokaʻawale like ʻole (mm) ʻoki ʻoki ʻana (mm)
1 ≤32 0.3 0.3/100
2 40~65 0.4 0.4/100
3 80~100 0.5 0.5/100
4 125~150 0.6 0.5/100
6. Ma hope o ka hana ʻia ʻana o ka paipu wili, e nānā iā ia me kahi mea ana i hoʻopaʻa ʻia.Inā loaʻa nā paipu paipu o nā kikoʻī like, ʻoi aku ka maikaʻi o ka hoʻohālikelike ʻana i nā paipu paipu.ʻO ke kiʻekiʻe o ka hoʻokuʻu wale ʻia e pono ke wili ʻia e ka lima, a ʻaʻole pono e wehe loa inā e hoʻopili ʻia nā mea paipu.Inā ʻaʻole hiki ke wili ʻia a ʻoi aku ka paʻa o ka wili, hiki ke hoʻihoʻi wale ʻia.ʻAʻole ʻae ʻia ka wili ikaika.
7. Pono e ma'ema'e a ma'amau ka milo i hoopa'i 'ia.ʻAʻole pono e ʻoi aku ka 10% o ka nui o nā milo i haki a nalo paha.Pono e pale ʻia ka papa galvanized ma ka ʻili o waho o ka pipeline.Pono e mālama ʻia nā ʻāpana i hōʻino ʻia me ka lāʻau anti-corrosion.
8. Hoʻohui ʻia ʻO ke kumu o ke kaula paipu ma hope o ka hoʻokomo ʻana o ka paipu e loaʻa iā 2 ~ 3 mau kaula i ʻike ʻia, a pono e hoʻomaʻemaʻe ʻia ka uea hemp keu a mālama ʻia me ka lāʻau anti-corrosion.
