Wear -paipu kila pale (Wear resistant steel), i ʻike ʻia hoʻi ʻo -paipu kūpaʻa, hana ʻia me ka pā kila a i ʻole ke kaula kila ma hope o ka wili ʻia ʻana ma hope o ka wili ʻana. He mea maʻalahi ke kaʻina hana o ka paipu pale ʻaʻahu, ʻoi aku ka maikaʻi o ka hana ʻana, nā ʻano a me nā kikoʻī, ʻoi aku ka liʻiliʻi o nā lako, akā ʻoi aku ka ikaika ma mua o ka paipu kila ʻole. Mai ka makahiki 1930, me ka ulu wikiwiki ʻana o ke kila kiʻekiʻe -ʻoi aku ka maikaʻi o ka hana ʻōwili mau ʻana a me ka holomua o ka wiliwili a me ka ʻenehana nānā ʻana, ua hoʻomaikaʻi mau ʻia ka maikaʻi o ka weld, ua hoʻonui ʻia nā ʻano a me nā kikoʻī o nā paipu kūpaʻa ʻaʻahu, a ua hoʻololi ʻia nā paipu kila maʻemaʻe i ka nui o nā kula. Hoʻokaʻawale ʻia nā paipu pale ʻaʻahu i nā paipu wili wili pololei a me nā paipu wiliwili spiral e like me ke ʻano o nā hui wili.
Hoʻopili i ka paipu pale lole
ʻO ka ʻaoʻao o waho he paipu kila maʻemaʻe a i ʻole paipu wili wili pololei ʻia, ʻo ka pā o loko e ʻaʻahu ʻia -paʻa seramika kūpaʻa pale ʻo AL2O3 ma ke ʻano he kumu kumu (ʻo ia ka corundum ceramics), me nā oxide metala like ʻole e like me ka flux, ma hope o hoʻokahi kaukani ʻehiku haneli degere kiʻekiʻe ka ʻala ʻana i nā seramika corundum kūikawā, a laila me ka lāʻau kūikawā / ka ikaika kiʻekiʻe. hui pū ʻana o nā huahana. He 6-12 mm ka manoanoa o ka paia o waho, a he 6-16 mm ka paia o loko. ʻAʻole i kaupalena ʻia e ke anawaena paipu.
Nā huahana pale: paipu kikowaena liner, China pipe center liner mea hana, mea hoʻolako, hale hana
