Ka hopena o ka maikaʻi o ka Coil Rolled Hot i ka hoʻokumu ʻana a me ka wili ʻana o ka paipu HFW

I nā makahiki i hala iho nei, me ka hoʻohana ʻana i nā wili wela e like me nā mea maka, ua hoʻohana nui ʻia ke kaʻina hana o ka HFW high-frequency welding + thermal tension reduction + full tube body heat treatment e hana i nā pahu kila kiʻekiʻe.Ma nā noi hana, ʻike ʻia ka maikaʻi o nā ʻōwili wela wela e pili pono i ka maikaʻi o ka hoʻokumu ʻana, ka helu hana ʻāpana a me ka hua o nā paipu welded HFW.

No laila, ma ka nānā ʻana i nā kumu hoʻohālikelike o ka maikaʻi o ka ʻōwili wela wela, a laila hoʻomaikaʻi i ka hoʻoheheʻe ʻana, ka ʻōwili ʻana a me ka ʻokiʻoki a me nā kaʻina hana ʻē aʻe e hoʻomalu ai i ka maikaʻi o ka wili wela wela, hiki iā ia ke hāʻawi i kahi hōʻoia maikaʻi no ka hoʻokumu ʻana a. wiliwili o ka paipu wiliwili.

ʻEhā ʻaoʻao:

(1) Hoʻolālā kūpono o ka hui kemika o ka coil, ma o ka hoʻomaikaʻi ʻana i ke kaʻina hoʻoheheʻe a me ka ʻōwili ʻana, e hōʻemi ana i ka hoʻolālā band, e hōʻemi ana i nā inclusions, a me ka hoʻomaikaʻi ʻana i ka maʻemaʻe o nā mea maka, hiki ke hoʻomaikaʻi maikaʻi i ka weldability a me ka hana piha. ka paipu wiliwili HFW.

(2) ʻO ka mana pololei o ka pololei geometrical dimensional o ka pā i hoʻopili ʻia mai ke kaʻina o ka ʻōwili ʻana, ka ʻoki ʻana a me ka wili lihi hiki ke hāʻawi i kahi hōʻoia no ka hoʻokumu pololei ʻana a me ka hoʻopaʻa paʻa ʻana o ka pahu blank, a i ka manawa like, pono ia. e hoʻomaikaʻi i ka pololei geometrical o ka huahana hope.

(3) Ma ka hoʻonui ʻana i ke kaʻina hana ʻōwili wela a me nā mea hana, ka mālama ʻana i nā hemahema e like me ka camber bend, ka hale kiaʻi, ka nalu nalu, ka lua, ka ʻōpala, a me nā mea ʻē aʻe, hiki ke hoʻomaikaʻi maikaʻi i ka maikaʻi o ka hoʻokumu ʻana a me ka maikaʻi o ka paipu welded HFW, a hoʻomaikaʻi i ka hua mai.

(4) Ma o ka optimization o ka slitting kaʻina hana, hiki i ka coiled plate ke loaʻa i ka maikaʻi ʻāpana maikaʻi, a i ka manawa like, hiki ke koho ʻia ke ʻano uncoiling maikaʻi loa i ka wā e hānai ai, hiki ke hana i nā kūlana maikaʻi no ka HFW welded pipe e hana ana a me ka weld a me ka weld. ka wehe ʻana i ka ʻeke.
