♦ He paʻa ka hao ductile, hiki ke kū i ke koʻikoʻi mechanical a me ka hoʻomāinoino kino, hiki ke waiho ʻia ma ka ʻāina maikaʻi ʻole a me nā kūlana hana a hana me ka hāʻawi ʻole ʻana i kahi ola lawelawe lōʻihi.
♦Paipu hao ductile, nā lakoa hoʻohana ʻia nā mea hana no ka lawe ʻana i ka wai inu a me ka wai ʻino ma nā wahi he nui e like me nā ʻupena wai inu, nā ʻupena wai, nā ʻōnaehana ahi a me nā ʻōnaehana wai HVAC.
♦ Pono o nā paipu hao ductile a me nā mea pono:
• Ka ikaika tensile kiʻekiʻe, ka modula elastic maikaʻi a me ka ductility maikaʻi loa, kūpono ia no nā noi koʻikoʻi kiʻekiʻe a me kahi e ʻike ʻia ai ka piʻi ʻana.
• Ke kū'ē i ka corrosion kiʻekiʻe.
• Ke kahe hydraulic maikaʻi loa.
• Kiʻekiʻe ke kaomi hana i hoʻohālikelike ʻia me nā ʻano paipu ʻē aʻe.
• ka maʻalahi o ka hoʻokomo.
• Ke ola lōʻihi.
•Hiki ke hoʻokomo i ka grka neʻe ʻana.
♦ Ka uhi:
Ka uhi waho:
Paipu BS EN545: ka uhi ʻana i ka zinc metala me ka papa hoʻopau
Nā lako BS EN545: ka uhi pena i ka zinc me ka papa hoʻopau
BS EN598 paipu a me nā mea pono: pena epoxy
♦ Ka pale o loko
BS EN545: ka sulphate kūpaʻa ʻia i ka lepo lepo
BS EN598: ʻO ke kiʻekiʻe kiʻekiʻe o ka alumini sima moka
