He mea maʻalahi loa ka lawe ʻana a me ka hoʻokomo ʻana i ka seramika, ka paipu kila i hoʻopaʻa ʻia a me ka paipu kila, ka paipu hoʻoheheʻe ʻana i ka ʻaʻahu, ka paipu hao a me ka paipu pōhaku hoʻohālikelike, maʻalahi ke kaumaha, maʻalahi ke lawe. Hiki ke welded, flanges, nā mea hoʻopili maʻalahi a me nā ala pili wikiwiki ʻē aʻe, no laila ua maʻalahi ke kau ʻana.

Ma ka ʻoihana:
1. Kiekie lole pale aku koi paipu: thermal mana, wela mana mea kanu lehu (slag) lawe, lanahu pipeline, concentrator tailings a me concentrate pipelines, awa a me ka sediment slurry pipeline pulverized lanahu slurry pipelines a me na mea like.
2. Dense Medium koho (holoi) lanahu mea kanu lanahu pipeline, kiʻekiʻe corrosion kū'ē koi o ka thermal mana desulphurization pulp pipelines.
3. Na paipu alumini hehee.
4. E koi ana i ka pale lole kiʻekiʻe, ke kūpaʻa corrosion kiʻekiʻe, ke ʻano wela kiʻekiʻe o nā kahawai.
