He aha ka waihoʻoluʻu kumu pololei humuhumu kila paipu? Hoʻohana ia i nā paipu kila kalapona no ka hana ʻana i nā paipu kila humuhumu pololei i kēia manawa, nā paipu kila humuhumu pololei 90-degere, nā paipu kila humuhumu pololei 45-degere, nā poʻo, nā ʻūhā kuʻekuʻe Hebei, a me nā mea pono paipu welded ʻole me ka pena ʻole a me ka anti-corrosion. kala mua. He ʻulaʻula kēia waihoʻoluʻu (peia ke ʻano o ka hana ʻana o nā paipu kila humuhumu pololei i ka wā o ka hana ʻana), a me ka cyan, ʻo ia ka waihoʻoluʻu kumu o nā paipu kila humuhumu pololei. Ua hana ʻia nā paipu kila humuhumu pololei mua a ʻaʻole hiki ke kūʻai ʻia me ka pena anti-rust. ʻO ka hapa nui o lākou he huahana semi-finished. Ua aneane lilo ia i lula ʻoihana. A i ʻole, ʻaʻole i manaʻo ʻia he paipu kila humuhumu pololei piha. I ka wā o ke kūkulu ʻana i ka hoʻoilo, ʻaʻole maʻalahi nā paipu i ka hopena a me ka haki ʻana, e hoʻonui ai i ka maʻalahi o nā hoʻonohonoho kūkulu. He pili kaiapuni a hiki ke hana hou ia me ka hoʻohaumia ʻole i ke kaiapuni. ʻO ka hana ʻole ʻana e hoʻopōʻino i ka lua; aia nā pilikia e like me ka hoʻomalu ʻana i ka degere cross-linking a me ka hoʻohui like ʻana, a paʻakikī ka hana ʻana a pili pono i ka hana o ka paipu.

ʻElua mau mea e aʻo iā ʻoe pehea e ʻike ai i nā paipu kila humuhumu pololei:
Hoʻokaʻawale ʻia nā paipu kila humuhumu pololei e like me ko lākou anawaena o waho: ʻo nā mea me nā anawaena o waho ma waena o φ4.76 a me φ12.70 mm he mau paipu kila humuhumu pololei; ʻo ka poʻe me nā anawaena waho ma waena o φ13-φ114 mm he mau paipu kila humuhumu pololei liʻiliʻi; ʻO ka poʻe me ke anawaena o waho ma waena o φ114 a me φ406 mm, he mau paipu kila ma waena o ke anawaena; ʻO ka poʻe me ke anawaena o waho i ʻoi aku ka nui ma mua o φ406 mm he mau paipu kila maʻa-pololei.

E hoʻokaʻawale i nā paipu welded e like me ka mānoanoa o ka paia:
E like me ka lakio o ka mānoanoa o ka pā t i ka paipu kila o waho anawaena D, hiki ke maheleia na paipu welded i keia mau mahele elima: ① ka poe me ka t/D emi malalo o 2%, he mau paipu wiwi paia; ② ʻo ka poʻe me ka t/D e like me 2-5% he mau paipu pā lahilahi; ③t/D ʻO ka poʻe me ka at/D ʻoi aku ka nui ma mua o 5-12% he mau paipu kumu maʻamau; ④ ʻo ka poʻe me ka t/D ʻoi aku ka nui ma mua o 12-18% he paipu pā mānoanoa; 5) ʻo ka poʻe me ka t/D ʻoi aku ka nui ma mua o 18% he mau paipu paia kumu kūikawā.

ʻAʻole ʻokoʻa ka manaʻo o nā paipu pā lahilahi, nā paipu pā maʻamau, a me nā paipu pā mānoanoa e ka waiwai o ka mānoanoa o ka pā. Eia naʻe, ʻekolu mau mānoanoa pā like ʻole o kekahi mau maʻamau e pili ana i ke anawaena o waho. Hiki ke kapa ʻia nā paipu me kēia mau mānoanoa pā ʻekolu, ʻo nā paipu pā lahilahi, nā paipu wili mānoanoa o ka paia, a me nā paipu kila humuhumu pololei mānoanoa.

Ma muli o ke kūpaʻa ʻana o ka corrosion, ka pale ʻana o ka oxidation, anti-static, a me nā hana kūikawā ʻē aʻe o nā paipu wili wili pololei, a me ka nani o ka helehelena a me ka lōʻihi o nā paipu wili wili pololei, ua lilo ia i mea maʻamau e hoʻohana iā lākou e hana i nā mīkini. , nā ʻāpana, a me nā pūnāwai. Ke hoʻomau nei ke kaʻina hana ʻenehana i ke oʻo a me ka paʻa ʻana, ʻo ka "Xiangyang" huahana huahana pololei seam welded paipu, ka mea i hoʻomau i ka ulu a me ka hoʻomohala ʻana i nā makahiki i hala iho nei, ke komo mālie nei i nā ʻano like ʻole e like me ka lako pono a me ke kūkulu ʻana a me ka ʻoihana hoʻonaninani me kāna ʻano ʻokoʻa. hana a me ka hana polynomial. A i ka wā e kamaʻāina ai ka poʻe, e ʻoi aku ka wikiwiki o kāna koi, a ʻoi aku ka nui o kāna mau kahua noi. ʻO kekahi laʻana, ʻo ia ka hoʻohana nui ʻana i nā koʻokoʻo wiliwili a me ka nui o nā ʻāpana kila kila, nā mea hoʻohui, a me nā mea ʻē aʻe, nona nā māla i noho nui ʻia e nā paipu wili wili pololei. Eia kekahi, me ka hoʻomohala ʻana i ka laina piha a me ka hoʻohana pono ʻana o nā huahana kiʻekiʻe, ke hoʻonui nei ka hoʻohana ʻana o nā paipu wili wili pololei. Nui nā ʻoihana e koi ana i nā mea hou i hoʻohana i nā paipu wili wili pololei. ʻO nā mea i maopopo loa ʻo ia ka ʻoihana kemika a me ka ʻoihana fiber chemical. ʻO ka hoʻololi ʻana i nā mea hana ʻoihana.
