He aha ka paipu kila boiler?
ʻO nā paipu kila boiler e pili ana i nā mea kila e hāmama ana ma nā ʻaoʻao ʻelua a loaʻa nā ʻāpana hollow me ka lōʻihi nui e pili ana i ka wahi a puni. E like me ke ʻano hana, hiki ke hoʻokaʻawale ʻia lākou i nā paipu kila seamless a me nā paipu kila welded. Hoʻoholo ʻia nā kikoʻī o nā paipu kila e nā ana o waho (e like me ke anawaena o waho a i ʻole ka lōʻihi o ka ʻaoʻao) a ua hōʻike ʻia ka mānoanoa o Wall ma kahi ākea o nā nui, mai nā puʻupuʻu capillary me nā anawaena liʻiliʻi loa i nā paipu anawaena nui me nā anawaena o kekahi mau mika. Hiki ke hoʻohana ʻia nā paipu kila i nā pipelines, nā mea wela, ka ʻoihana mīkini, ka ʻimi ʻana i ka honua, nā ipu, ka ʻoihana kemika, a me nā kumu kūikawā.

Nā noi o nā paipu kila boiler:
ʻO nā paipu i hoʻohana ʻia i loko o nā paila ʻoihana ʻoi aku ka nui o nā paipu kila maʻemaʻe no ka mea hiki i nā hōʻailona hana o nā paipu kila ʻole ke hoʻokō pono i nā koi o nā noi boiler. ʻOiai he kiʻekiʻe ke kumukūʻai, he kiʻekiʻe ko lākou palekana a me ka hilinaʻi. Hoʻohana pinepine ʻia nā paipu kila welded e like me nā paipu lawe wai haʻahaʻa i loko o 2Mpa. Pono e hoʻohana i nā mea wela kiʻekiʻe a me nā mea paʻi kiʻekiʻe e like me nā paila ʻoihana i nā paipu kila maʻemaʻe, a ʻo ka mānoanoa o ka pā paipu e like me ka mānoanoa. Hoʻohana ʻia nā paipu kila welded i kēia manawa i nā boilers medium a me ka haʻahaʻa haʻahaʻa, mahalo i ka hoʻomaikaʻi wikiwiki ʻana o ka ʻenehana wili. No ka laʻana, ke hoʻopili ʻia nā paipu i nā paipu kila friction-welded, ʻaʻole ʻokoʻa ka microstructure o nā hui. Eia kekahi, ma hope o ka hoʻoheheʻe ʻia ʻana o nā ʻili paipu ma nā ʻāʻī a me nā hui kihi, he paʻakikī ke nānā ʻana i nā kaha hili me ka maka ʻōlohelohe. Ua like ka microstructure o kona mau ʻāpana me nā paipu kila friction-welded. Ua like ia me ka humuhumu.
