Nā Bolts Hex Kaumaha [Paʻa 3] (ASTM A307)

No ka hoʻopaʻa paʻa paʻa a hilinaʻi hoʻi i nā noi hana kaumaha, hilinaʻi i nā bolts hex kaumaha mai ASTM A307. Me kā lākou mau mea kiʻekiʻe kiʻekiʻe, hana pololei, a me nā pale pale corrosion, hāʻawi kēia mau bolts i ka hana maikaʻi a me ka lōʻihi.

Hoʻohālike:ASME B 18.2.1

Nā mea hoʻopaʻa paʻa paʻa:ʻO nā bolts hex kaumaha, e like me ka mea i hōʻike ʻia ma ka Papa 3 (ASTM A307), ua hana ʻia e hāʻawi i ka paʻa paʻa a hilinaʻi i nā noi like ʻole. Me kā lākou hana paʻa a me ka nui o ke poʻo nui, hāʻawi kēia mau bolts i ka ikaika a me ka lōʻihi, e hoʻolilo iā lākou i mea kūpono no nā ʻāpana hana kaumaha a me nā hui mechanical.

Mea Kiʻekiʻe Kiʻekiʻe:Hana ʻia mai ke kila kalapona ikaika nui, nā kī hex kaumaha mai ASTM A307 e pili ana i nā kūlana koʻikoʻi koʻikoʻi, e hōʻoia ana i ka hana maikaʻi loa a me ka lōʻihi. ʻO kā lākou mau waiwai waiwai ʻokoʻa ke kūpaʻa iā lākou i ka ʻaʻahu, deformation, a me nā koʻikoʻi mechanical, ʻoiai i nā wahi koi.

Hana pololei:Hoʻokomo ʻia kēlā me kēia pahu hex kaumaha i nā kaʻina hana kūpono e hoʻokō i ka pololei dimensional a me nā koi hoʻomanawanui. ʻO kēia nānā i nā kikoʻī e hōʻoia i ka maikaʻi a me ke kūpono kūpono, pono no ka paʻa paʻa a paʻa i nā noi koʻikoʻi.

Nā mea hoʻohana like ʻole:Me ka nui o ka nui o ke kaula, ka lōʻihi, a me nā anawaena i loaʻa, ʻo nā bolts hex kaumaha nā mea hoʻopaʻa paʻa kūpono no nā ʻoihana like ʻole a me nā noi. Inā hoʻohana ʻia i ke kūkulu ʻana, ka ʻenehana, a i ʻole nā mīkini, hāʻawi kēia mau bolts i ka ikaika clamping hilinaʻi a me ka pololei o ka hoʻolālā.

Paʻa ʻino:No ka hoʻomaikaʻi ʻana i ka lōʻihi a me ka lōʻihi, hiki ke uhi ʻia nā bolts hex koʻikoʻi me nā hoʻopau ʻana i ka corrosion e like me ka zinc plating a i ʻole hot-dip galvanization. Hāʻawi kēia mau uhi i ka pale maikaʻi i ka ʻōpala a me ka corrosion, e hoʻolōʻihi i ke ola lawelawe o nā bolts a me nā hale a lākou e kākoʻo ai.

Hana i hōʻoia ʻia:ʻO nā bolts hex kaumaha e like me ASTM A307 e hoʻāʻo a me ka hōʻoia e hōʻoia i ka hoʻokō ʻana i nā kūlana ʻoihana. Ma ke koho ʻana i nā bolts i hōʻoia ʻia, hiki i nā mea hoʻohana ke hilinaʻi i kā lākou hana a me ka hilinaʻi, ʻoiai i nā wahi koi a me nā koʻikoʻi kiʻekiʻe.

Kūkākūkā akamai:Ke koho ʻana i nā bolts hex kaumaha no nā noi kikoʻī, pono e kūkākūkā me nā loea hoʻopaʻa hiki ke hāʻawi i ke alakaʻi i ke koho ʻana i ka nui o ka bolt kūpono, ka pae, a me ka uhi no ka hana maikaʻi loa a me ka lōʻihi.
