ʻO nā paipu pā i hoʻomaʻamaʻa ʻia i ka wai paila: kū i ka wela wela o ke kinoea wela wela i loko o ka paila, hoʻololi i ka wai e hana i ka mahu, a koi i nā paipu e loaʻa i ke kūpaʻa wela kiʻekiʻe a me ka pale ʻana i ka corrosion.

ʻO nā paipu hoʻoheheʻe wela nui: hoʻohana ʻia e hoʻomaʻamaʻa hou i ka mahu saturated i loko o ka mahu wela, e koi ana i nā paipu e loaʻa ka ikaika kiʻekiʻe a me ka paʻa ma lalo o nā kūlana wela kiʻekiʻe.

ʻO nā paipu boiler economizer: hoʻihoʻi hou i ka wela ʻōpala i ke kinoea flue a hoʻomaikaʻi i ka maikaʻi o ka wela, e koi ana i nā paipu e loaʻa i ka conductivity thermal maikaʻi a me ka pale ʻana i ka corrosion.

ʻO nā paipu locomotive mokumahu: me nā paipu mahu superheated a me nā paipu wai paila, hoʻohana ʻia e hoʻouna i ka mahu kiʻekiʻe a me ke kaomi kiʻekiʻe a me ka wai wela, e koi ana i nā paipu e loaʻa ka ikaika mechanical maikaʻi a me ke kūpaʻa wela kiʻekiʻe.

I ka pōkole,GB3087 paipu kila maʻemaʻeHe mea koʻikoʻi ia i ka ʻoihana hana boiler kaomi haʻahaʻa a me waena. Ma ke koho ʻana i nā mea kūpono a me nā kaʻina hana, hiki ke hoʻomaikaʻi maikaʻi ʻia ka hana pono a me ka palekana o ka boiler e hoʻokō i nā pono o nā ʻano hana like ʻole.
