Introduction to pipe bending process
1: Hoʻomaka i ka hoʻolālā mold a me ke koho

1. Hookahi paipu, hookahi poni
No ka paipu, ʻehia ka nui o nā piʻo, ʻaʻohe mea e pili ana i ke ʻano o ka piʻo ʻana (ʻaʻole pono e ʻoi aku ma mua o 180°), pono ke ʻano like ʻole ka radius kulou.No ka mea, he ho'okahi ka po'i o ka paipu, he aha ka radius piko kupono no na paipu me na anawaena okoa?ʻO ka liʻiliʻi liʻiliʻi liʻiliʻi e pili ana i nā waiwai waiwai, ke kihi kuʻi, ka ʻae ʻia o ka thinning ma waho o ka paia paipu kulou a me ka nui o nā wrinkles ma loko, a me ka ovality o ka piko.ʻO ka ʻōlelo maʻamau, ʻaʻole pono e emi ka radius liʻiliʻi liʻiliʻi ma mua o 2-2.5 mau manawa o ke anawaena o waho o ka paipu, a ʻo ka ʻāpana laina pololei pōkole ʻaʻole e emi iho ma mua o 1.5-2 mau manawa o ka anawaena o waho o ka paipu, koe wale no nā kūlana kūikawā.

2. Hoʻokahi paipu a me ʻelua mold (composite mold or multi-layer mold)

No nā kūlana ʻaʻole hiki ke hoʻokō ʻia hoʻokahi paipu a me hoʻokahi poni, no ka laʻana, he liʻiliʻi ka wahi o ka hui hui o ka mea kūʻai aku a ua kaupalena ʻia ka hoʻolālā pipeline, e hopena i kahi paipu me nā radii lehulehu a i ʻole kahi ʻāpana laina pololei pōkole.I kēia hihia, i ka hoʻolālā ʻana i ka mold kuʻekuʻe, e noʻonoʻo i ka mold Layer pālua a i ʻole multi-layer mold (i kēia manawa ke kākoʻo nei kā mākou mea kūlou i ka hoʻolālā ʻana a hiki i 3-layer molds), a i ʻole multi-layer composite molds.

ʻĀpana pālua a i ʻole ʻāpana-nui: ʻO kahi paipu he pālua a ʻekolu paha radii, e like me ka mea i hōʻike ʻia ma kēia laʻana.

ʻO ka papalua a i ʻole nā ​​ʻāpana ʻāpana he nui: pōkole ka ʻāpana pololei, ʻaʻole kūpono i ka hoʻopili ʻana, e like me ka mea i hōʻike ʻia ma kēia hiʻohiʻona.
