Nā ʻaʻahu

No ka hoʻomaopopo ʻana i kahi leak-free flange connect gaskets pono.

ʻO nā Gaskets nā ʻāpana a i ʻole nā ​​apo i hoʻohana ʻia e hana i kahi sila kūpaʻa wai ma waena o nā ʻaoʻao ʻelua. Hoʻokumuʻia nā Gaskets e hana ma lalo o ka wela wela a me nā pilikia a loaʻa i ka nui o nā mea metala, semi-metallic a me nā meaʻole.

ʻO ke kumumanaʻo o ka hoʻopaʻa ʻana, no ka laʻana, ʻo ke kaomi ʻana mai kahi gasket ma waena o ʻelua flanges. Hoʻopiha ka gaskets i nā wahi microscopic a me nā hewa ʻole o nā alo flange a laila hana ia i kahi sila i hoʻolālā ʻia e mālama i nā wai a me nā kinoea. ʻO ka hoʻokomo pololei ʻana i nā gaskets manuahi ʻole he koi no ka hoʻopili flange leak-free.

Ma kēia pūnaewele e wehewehe ʻia nā gaskets ASME B16.20 (Metallic and semi-metallic gaskets no Pipe flanges) a me ASME B16.21 (Nonmetallic flat gaskets for pipe flanges).

Ma kaNā ʻaʻahuʻaoʻao e ʻike ʻoe i nā kikoʻī hou aku e pili ana i nā ʻano, nā mea a me nā ana.

ʻO nā kīʻaha

No ka hoʻohui ʻana i ʻelua flanges me kekahi i kekahi, pono pū nā bolts.

E hāʻawi ʻia ka nui e ka helu o nā puka bolt i kahi flange, ke anawaena a me ka lōʻihi o nā bolts e pili ana i ke ʻano o ka flange a me ka Class Pressure o ka flange.

ʻO nā bolts i hoʻohana nui ʻia ma Petro a me ka ʻoihana kemika no nā flanges ASME B16.5 he Stud Bolts. Hana ʻia nā Stud Bolts mai ke koʻokoʻo i hoʻopaʻa ʻia a me ka hoʻohana ʻana i ʻelua nati. ʻO ke ʻano ʻē aʻe i loaʻa ʻo ia ka mīkini pahu e hoʻohana ana i hoʻokahi nut. Ma kēia pūnaewele wale nō e kūkākūkā ʻia nā Stud Bolts.

Ua wehewehe ʻia nā ʻāpana, nā ʻae ʻana a me nā mea ʻē aʻe i ka maʻamau ASME B16.5 a me ASME 18.2.2, nā mea i nā kūlana ASTM like ʻole.

Ma kaNā Bolts Studʻaoʻao e ʻike ʻoe i nā kikoʻī hou aku e pili ana i nā mea a me nā ana.

E ʻike pū i ka Torque Tightening a me Bolt Tensioning ma ka papa kuhikuhi nui "Flanges".
