Ka nānā 'ana i ke ka'ina hana flange butt welding

1, puʻu welding flangeʻO ka mahana annealing a hiki i ka mahana i kuhikuhi ʻia,puʻu welding flangeHoʻohana maʻamau ka mālama ʻana i ka mālama wela, ʻo ia hoʻi, ka poʻe i kapa ʻia ʻo "annealing", ʻo ka pae wela he 1040 ~ 1120 ℃. Hiki iā ʻoe ke nānā ma o ka puka nānā ʻana o ka umu annealing, kaflangeʻO nā mea hoʻokomo i loko o kahi annealing e pono ke kukui, akā ʻaʻohe ʻano palupalu palupalu.
2, ka lewa annealing,puʻu welding flangeHoʻohana maʻamau e like me ka lewa hydrogen annealing maʻemaʻe, ʻoi aku ka maʻemaʻe o ka lewa ma mua o 99.99%, inā he kinoea inert ka ʻāpana o ka lewa, hiki ke emi iki ka maʻemaʻe, akā ʻaʻole hiki ke loaʻa ka nui o ka oxygen, ka wai mahu. .

ʻO ka flange welding butt
3, puʻu welding flangepale kinoea kaomi, i mea e pale aku aipuʻu welding flangeleakage, pono e mālama ke kinoea pale umu ahi i kekahi kaomi maikaʻi, inā he kinoea hoʻomalu hydrogen, ʻoi aku ka nui ma mua o 20kBar.
4, welding flangeka hana ʻana i ka mahu wai i loko o ka umu hoʻolei, ma kekahi ʻaoʻao, e nānā inā ua maloʻo ka mea umu, pono e hoʻomaloʻo ʻia ka mea umu no ka manawa mua; ʻO ka lua inā paha kaflangeʻO nā paipu paipu i loko o ka umu ahi e waiho nui loa i nā ʻili wai, ʻoi aku ka nui inā he mau puka i loko o nā paipu flange pipe, ʻaʻole e kahe i loko, i ʻole e luku loa ʻia ka lewa umu.
5, puʻu welding flangehoʻopaʻa kino i ka umu ahi,puʻu welding flangepono e pani ʻia ka umu ahi annealing, hoʻokaʻawale ʻia mai ka ea waho; Me ka hydrogen ma ke ʻano he kinoea pale, hoʻokahi wale nō puka e hāmama. Hiki ke hoʻohana ʻia ke ʻano o ka nānā ʻana e holoi i nā māwae o kēlā me kēia hui i loko o ka umu annealing me ke kopa a me ka wai e ʻike ai inā e holo; Ma waena o lākou, ʻo kahi maʻalahi o ka holo ʻana, ʻo ia kahi e komo ai ka umu annealing i ka paipu a me kahi e puka ai ka paipu. ʻO ke apo hoʻopaʻa ma kēia wahi he maʻalahi loa ia e ʻaʻahu a haehae, no laila pono e nānā a hoʻololi pinepine ʻia.
