ʻO ka mea mua, ʻo ka haki ʻana o ka stainlesshili kilakemika haku mele 'ana, hō'ike nā hualoa'a i ka haku mele 'ana o ke kila kilaflange a me ka wiliwiliʻikepili e pili ana i nā kikoʻī pili. Hoʻopau ʻia ka paʻakikī brinell o ka ʻāʻī flange a me ka ili hoʻopaʻa ʻana i kēlā me kēia, a ʻo ka waiwai paʻakikī Brinell e hoʻokō i nā koi. Ma ka manaʻo i kūpono ka hui ʻana o ka ʻikepili, ua hoʻokō ka mea paipu i nā koi ʻenehana, ua kūpono ka hoʻāʻo ʻana o ka paʻakikī, a me ka hana maʻamau o ka hoʻāʻo paʻi, ua haki ka flange pipe i ke kaʻina o ka hoʻāʻo kaomi. Ua wehewehe ʻia e pili ana nā hemahema i ke ʻano o loko o ka flange a i ʻole nā ​​​​mea ʻike ʻole.

Ka leakageflangeʻoki ʻia mai ka pipeline, flannel, e hoʻōki i ka nānā ʻana i ka macro, ʻike ʻia ʻo ka flange i loko o ke ʻano o nā māwae, 3mm ka lōʻihi, 0.5mm ākea, māwae a me kona ʻaoʻao hema i hana i nā ʻōpala; Nui nā māwae i ʻike ʻia i loko o nā lua o ka flange bolt.

Nui nā mea hoʻokomo ʻole i loaʻa ma ka ʻili hoʻopaʻa o ka flange kila kila a me nā kūlana ʻē aʻe. Ua hana ʻia kekahi mau lua liʻiliʻi ma muli o ka hoʻopuehu ʻana ma luna o ka ʻili o ka flange sealing surface. ʻO nā lua he 2.0mm ka nui a me ka 0.8mm ka nui, a ʻo ka lihi o nā lua he mau māwae liʻiliʻi i ʻike ʻia e ka maka ʻōlohelohe. Hoʻonohonoho ʻia ka pūʻulu like o nā austenitic stainless steel flanges no ka nānā ʻana macro kahua.

Ua ʻike ʻia ka nui o nā flanges i nā hemahema ma nā pae like ʻole, a ʻo kekahi mau flanges i ʻike ʻia e ka maka ʻōlohelohe. Hōʻike hou aku nā hualoaʻa noʻonoʻo macroscopic he pilina ko ka puʻu welding flange, leakage flange a me ka flange ponoʻī. I mea e ʻimi hou ai i ke kumu maoli o ka leaka ʻana o ka flange, ua koho ʻia kahi ʻāpana o ka mea hana like a me ka pūʻulu like.
