He aha nā ʻano no ka hoʻonui ʻana i ke anawaena o waho o ka paipu kila hoʻoheheʻe ʻaila 20#? He aha nā pōmaikaʻi? Me ka hoʻomohala ʻana o ka ʻenehana ʻenehana a me ka ʻaila a me nā ʻoihana kemika, ua hoʻonui ʻia ka noi no nā paipu kila seamless nui i kēlā me kēia makahiki. ʻOiai ʻo ka nui o ka cyclic pipe rolling units a me ka paipu jacking units hiki ke hana i kekahi nui-diameter 20# oil cracking steel pipes, he nui kā lākou mea hana, he kiʻekiʻe ka hoʻopukapuka hoʻokahi manawa, a aia kekahi mau pilikia ʻenehana i ka hana ʻana i ka lahilahi nui. -paipu paia. Aia ka nui o nā ʻano hana no ka hoʻonui wela o nā paipu:

(1) Hoʻokō ʻia ka hoʻonui wela oblique rolling o 20# oil cracking steel pipe ma kahi mīkini hoʻonui oblique rolling. ʻO ka mīkini hoʻonui oblique rolling ʻelua ʻelua wili conical cantilevered i hoʻokomo ʻia i loko o kahi pahu pahu. ʻO nā hiʻohiʻona o ka hoʻonui oblique rolling o 20 # oil cracking steel pipe he deformation nui, wikiwiki deformation wikiwiki, a me nā huahana kiʻekiʻe. He kūpono ia no ka hana ʻana i nā paipu kila nui-diameter a me medium-thin-wall 20 # ʻaila māwae o nā ʻano kila like ʻole me ka pololei kiʻekiʻe kiʻekiʻe, akā ʻo kona mau hemahema ʻo ia ka nui o ka ʻāpana, kiʻekiʻe ka hoʻopukapuka, ʻaʻole hiki iā ia ke hana kūikawā. -ʻano a hoʻololi-ʻāpana seamless paipu.

(2) Hoʻokō ʻia ka hoʻonui wela o 20 # petroleum cracking steel pipe ma kahi mīkini hoʻonui huki wela. ʻO nā hiʻohiʻona e hiki i ka mīkini hoʻonui ke hoʻonui wela a me ka huki wela, ʻaʻole hiki ke hoʻonui wela i nā paipu pōʻai wale nō, akā huki pū kekahi i nā paipu ʻāpana kūikawā a me nā ʻāpana ʻāpana; He māmā nā mea hana o ke kaha kiʻi a me ka mīkini hoʻonui, liʻiliʻi ka hoʻopukapuka kālā, a maʻalahi ka mea hoʻololi; akā, no ka mea, ʻo ke kaha kiʻi a me ka hoʻonui ʻana he deformation manuahi, ʻaʻole kiʻekiʻe nā hemahema o ka 20 # petroleum cracking steel pipe extended products, a ʻaʻole kiʻekiʻe ka pololei o ka mānoanoa o ka pā a me ka pololei o waho.

(3) I kēia mau makahiki i hala iho nei, ua puka mai kahi kaʻina hana hoʻonui anti-inflammatory medium-frequency induction heating hydraulic two-step push-type anti-inflammatory, he ʻokoʻa ia mai ke kaʻina hana kuʻuna a me ka hoʻonui. Hoʻohana ʻia ia e hana i ka nui-diameter 20 # petroleum māwae kila. He mea maʻalahi ke kaʻina hana, a ʻo kēlā me kēia ʻāpana he ʻumi mau tona. Eia kekahi, ʻo ka hoʻonui ʻia ʻo 20 # petroleum cracking steel pipes ka hapa nui o ke ʻano o ke ʻano, me nā hua ʻoi aku ka maikaʻi a me nā waiwai mechanical maikaʻi. No laila, ua lilo i ka mea kaulana loa nui-anawaena 20 # aila māwae kila paipu hana hana.
