He aha ka paipu huinaha ikaika kiʻekiʻe?

ʻO nā hiʻohiʻona hana opaipu huinaha ikaika kiʻekiʻeka ikaika kiʻekiʻe, ka paʻakikī maikaʻi a me ke kū'ē i ka hopena.
Ka ikaika: helu hua（ σ s）≥390mpa；
Ka ikaika tensile（ б b）≥635mpa；
ka lōʻihi δ 5（%）≥25；
ʻO ka paʻakikī hb ≤ 187hv,
Heat lapaʻau kiko'ī: normalizing 850 ° C; Hoʻopau i ka 880 ° C; 600 ° C.
Material: hana ʻia me ke kūlana kiʻekiʻekalapona kila kilama ke kawili wela a i ʻole ke kaha anu.
Hoʻohana: hoʻohana ʻia no ka hana ʻana i ka paipu paʻa wai hoʻoluʻu, ka paipu wai paila, ka paipu wai pahu wai locomotive a me ka paipu pōhaku lepo, etc.
Hōʻike a me ka maikaʻi o ka helehelena:
ʻO kēlā me kēia pūʻulu opaipu kilae nana pakahi ia, a o ka ili he mau mawae, pelu a me na hemahema o ka ili; E mālama ʻia ka ʻike kīnā kani kani no kēlā me kēia paipu kila e nānā i nā waiwai mechanical o ka weld. ʻO ka maʻamau, ʻo ke anawaena hoʻoikaika lōʻihi o ka weld he 0.2-0.25mm, ʻo ke anawaena hoʻoikaika lōʻihi o ka weld circumferential he 0.75-1mm, a ʻo ka hoʻoikaika koʻikoʻi longitudinal ma ke kumu ʻaʻole e emi iho ma mua o 0.25mm.
Hoʻohui kemika ʻO ka hui kemika o ka huahana i hoʻopau ʻia e like me nā ʻōlelo o GB 222-84.
Nā waiwai kino a me ka mechanical:
1) E palahalaha ke ko'iko'i o ka ho'ā'o tensile me ka loli 'ole
2) Ho'āʻo Impact Hoʻāʻo ʻia ka paʻakikī haʻahaʻa haʻahaʻa haʻahaʻa o ka hāpana e ke ʻano hoʻāʻo hoʻoheheʻe anu i ka wela i ʻōlelo ʻia.
3) ʻAʻole ʻae ʻia nā māwae ma nā paipu i puhi ʻia e nā mea hydraulic a i ʻole pneumatic
4) ʻAʻole ʻoi aku ke koʻikoʻi o ka like ʻole o ka hoʻāʻo ʻana i ka piko i ka waiwai i kuhikuhi ʻia.
Ke kahe kaʻina hana: Ma hope o ka hoʻopaʻa ʻia ʻana o ke kaula kila i loko o kahi ʻano diski lahilahi a hana mau ʻia, hoʻopaʻa ʻia e ka multi-pass straightener, a laila komo i ka ʻāpana kuʻihao kiʻekiʻe. Hoʻopaʻa ʻia nā ʻaoʻao ʻelua e kahi welder puʻupuʻu kiʻekiʻe e hana i kahi kuʻi poʻo pōʻai. Ma hope o ke kuʻi ʻana, ua nui ka nui o ka paipu kila a ʻoki ʻia e ka nui a me ka ʻoki ʻana. ʻO ka hope, hoʻopiʻi ʻia ka paipu kila a hoʻomāliʻi ʻia e ka ʻāpana hoʻopau, a laila kāpī ʻia me ka primer e hoʻopau i ke kaʻina hana.
