He aha ka paipu huinaha ikaika kiʻekiʻe?

Nā ʻano hana opaipu huinahā ikaika kiʻekiʻehe ikaika kiʻekiʻe, paʻakikī maikaʻi a me ke kūpaʻa i ka hopena.
Ikaika: kiko hua (σ s) ≥390mpa;
Ikaika tensile (b b) ≥635mpa;
hoʻolōʻihi δ 5（%）≥25；
Paʻakikī hb ≤ 187hv,
Ka kikoʻī o ka mālama wela: hoʻomaʻamaʻa ʻana i 850 ° C; hoʻopau ʻana i 880 ° C; mahana 600 ° C.
Mea Hana: hana ʻia me ke ʻano kiʻekiʻekila kūkulu kalaponama ka ʻōwili wela a i ʻole ke kahakiʻi anu.
Hoʻohana: hoʻohana ʻia no ka hana ʻana i nā paipu paia wai-anuanu, ka paipu wai e hoʻolapalapa ana, ka paipu mahu pahu wai locomotive a me ka paipu brick arch, etc.
Nā kikoʻī a me ke ʻano o ka helehelena:
ʻO kēlā me kēia pūʻulu onā paipu kilae nānā ʻia hoʻokahi a hoʻokahi, a ʻaʻohe māwae, nā pelu a me nā kīnā ʻili pālua o ka ʻili; Pono e hana ʻia ka ʻike ʻana i nā kīnā ultrasonic no kēlā me kēia paipu kila e nānā i nā waiwai mechanical o ka weld. Ma ke ʻano laulā, ʻo ke anawaena hoʻoikaika longitudinal o ka weld he 0.2-0.25mm, ʻo ke anawaena hoʻoikaika longitudinal o ka weld circumferential he 0.75-1mm, a ʻaʻole e emi ka hoʻoikaika longitudinal stress ma ke kumu ma mua o 0.25mm.
ʻO ke ʻano kemika Ua kūlike ke ʻano kemika o ka huahana i hoʻopau ʻia me nā ʻōlelo o GB 222-84.
Nā waiwai kino a me nā waiwai mechanical:
1) Pono e pālahalaha ka piʻo stress-strain o ka hoʻāʻo tensile me ka ʻole o ka loli koke
2) Hoʻāʻo hopena Hoʻāʻo ʻia ka paʻakikī hopena haʻahaʻa o ka laʻana e ke ʻano hoʻāʻo kūlou anu ma ka mahana i kuhikuhi ʻia
3) ʻAʻole ʻae ʻia nā māwae ma nā paipu i hoʻā ʻia e nā mea hydraulic a pneumatic paha
4) ʻAʻole e ʻoi aku ka nui o ke kaumaha o ka hoʻāʻo kūlou ma mua o ka waiwai i kuhikuhi ʻia.
Ke kaʻina hana: Ma hope o ke kaula ʻakomi ʻia ʻana o ke kaula kila i loko o kahi ʻano disc lahilahi a hana mau ʻia, hoʻohālikelike ʻia e kahi straightener multi-pass, a laila komo i loko o ka ʻāpana wili alapine kiʻekiʻe. Hoʻopaʻa ʻia nā wēlau ʻelua e kahi wili lap alapine kiʻekiʻe e hana i kahi wili corrugated poepoe. Ma hope o ke wili ʻana, ua hoʻonui ʻia ka nui a ʻoki ʻia ka paipu kila e ka ʻāpana ana a me ka ʻoki ʻana. ʻO ka hope, ua kinai ʻia a hoʻomaʻamaʻa ʻia ka paipu kila e ka ʻāpana hoʻopau, a laila pīpī ʻia me ka primer e hoʻopau i ke kaʻina hana.
