Nīnau pinepine ka poʻe kūʻai: pili ʻana i ke kila kila flange inā e koho i nā ʻili kila kila?

I kēia manawa e kākau wau i nā mea aʻu i aʻo ai e kaʻana like me ʻoe:

ʻAʻohe mea pili i ka mea obolts flange, e like me ka ʻōnaehana ʻEulopa HG20613-97 "flange paipu kilame nā mea paʻa (ka ʻōnaehana ʻEulopa) HG20614-97"flange paipu kilanā mea hoʻopili gasket e koho (ka ʻōnaehana ʻEulopa), ka ʻōnaehana ʻAmelika e like me ka HG20634-97 "flange paipu kilame nā mea paʻa (pūnaewele) o ʻAmelika HG20635-97"flange paipu kilaʻōnaehana koho mea hoʻopaʻa kino (ʻAmelika), kila kalapona, kuhilikila flange koho ma'amau ka papa kūikawā 35 hiki i ka crmoa ke ho'okō i nā koi.

ʻO ke kila kilaʻaʻole pono e hoʻohana i nā kī kila kila, hoʻohana ʻia nā bolts stainless e hoʻomaʻamaʻa i ka wehe ʻana (he maʻalahi ke kila kalapona i ka ʻōpala), ma kekahi ʻaʻole hiki ke ahi a i ʻole nā ​​manawa kūikawā ʻē aʻe ke koho ʻia;

ʻAʻole pono ka hoʻohana ʻana i nā bolts carbon steel e hoʻohui i nā gaskets insulation a me nā bākeke, me nā gaskets insulation a me nā bākeke e hoʻohana wale ʻia no ka hiki ke electrified a i ʻole ka wai i loko o ka pipeline he flammable a me nā manawa pahū, pono hoʻi ka hoʻohana ʻana i nā bolts stainless steel. e hoʻohui i nā ʻeke a me nā bākeke.

ʻAʻole ʻo ka mea o ka flange ke kumu o ke koho ʻana i nā mea bolt, ʻoiai ua lawa ka ikaika pre-tightening.

Hoʻohana pinepine ʻia nā bolts Galvanized e pale i ka ʻōpala a me ka ʻino.
