Paipu huila ʻole
E pili ana i ka paipu huila ʻole
Ua manaʻo ʻia nā paipu kila kila he kiʻekiʻe ka chromium a me ka haʻahaʻa kalapona.Loaʻa i kēia mau paipu paila kila kila kila nā ʻano koʻikoʻi e pili ana i ka ductility kiʻekiʻe, ka pale ʻana i ka corrosion, a me ke koʻikoʻi pili i ka corrosion cracking resistance.No laila, hoʻohana maʻamau ʻia nā paipu kila i hoʻopaʻa ʻia e IBR i nā kaʻa kaʻa, nā lako kīhini a me nā mea hana ʻenehana.
ʻO ke kila kila kiʻekiʻe a me ke kila haʻahaʻa haʻahaʻa he ʻelua ʻano o ke kila kila.ʻO nā paipu kila haʻahaʻa haʻahaʻa he mau paipu me ka pākēneka alloying ma lalo o 5%.ʻO ka maʻiʻo o nā mea hao hao kiʻekiʻe mai ka 5% a hiki i ka 50%.E like me ka hapa nui o nā alloys, ʻoi aku ka kiʻekiʻe o 20% kiʻekiʻe ma mua o nā paipu welded.No laila, kūpono ke hoʻohana ʻana i nā paipu seamless i nā noi e koi ana i nā kaomi hana kiʻekiʻe.ʻOi aku ka nui o ke kumukūʻai ma mua o ka paipu welded, ʻoiai ʻoi aku ka ikaika.
Hoʻohana ʻia nā paipu ʻeleʻele Alloy steel no nā noi e koi ana i ka pale corrosion haʻahaʻa a me ka lōʻihi maikaʻi a me ke kumu kūʻai haʻahaʻa.Hoʻohana maʻamau ʻia nā paipu paila kila kila kiʻekiʻe no nā noi me nā mahana ambient a hiki i 500°C.No ka laʻana, ke hoʻohana ʻia ma ka rig wili, pono e hiki i nā paipu wili hao hao a me nā paia lahilahi ke kū i nā ʻokoʻa puʻupuʻu e kū mai ana i loko a i waho o kēia mau paipu hao ʻole.
ʻO ka hana ʻana o ka paipu huila kila kila
ʻO nā paipu boiler ASME SA213 maʻemaʻe i ka hana ʻana.He kūpono kēia no nā paipu me nā anawaena nui.ʻO ka mānoanoa o ka pā paipu mai 1mm a 200mm, a hiki i ka lōʻihi ke hiki i 12m.ʻOkoʻa nō hoʻi ka holomua a me ke kaomi ʻana o nā paipu hili ʻole.ʻO ke anawaena, ka mānoanoa o ka paia, a me ka papa hana e hoʻoholo ai i ka hiki ke kaomi o ka paipu.Ma ke ano o KEKAHI O NA PAPA PALAPALA ALLOY STEEL, HAAWI MAKOU I NA PAPA PALAPALA SCH40 A ME SCH80.Loaʻa nā paipu ASTM A213 i nā ʻano like ʻole e like me ka poepoe, square, rectangular a me hydraulic.Ua ana pū ʻia ka lōʻihi o ka paipu no ka nui o ka paipu paʻa paʻa, ʻoki ʻoki ʻia.Hiki ke loaʻa i nā ʻōpuʻu palahalaha a i ʻole nā wili o nā paipu ʻeleʻele huila, ma muli o nā koi noi.Loaʻa pū nā ʻaoʻao beveled.ʻO nā noi e koi ana i ka ikaika hoʻolālā e hoʻohana i nā paipu huinaha kila.Aia nā mea i ka carbon, manganese, phosphorus, sulfur, silicon a me 1% chromium a me molybdenum.ʻO kēia haku mele ke kuleana no ka ikaika haʻahaʻa haʻahaʻa o 205MPa a me ka ikaika tensile haʻahaʻa o 41 5MPa.Hoʻohana ʻia nā paipu paila SA213 i nā condensers, nā mea hoʻololi wela, nā paila a me nā ʻāpana e kū i nā wela kiʻekiʻe a me nā kaomi.
Mechanical waiwai o galvanized kila paipu，Hoʻomaʻemaʻe ʻano
1. ka hoʻohana mua ʻana o ka solvent hoʻomaʻemaʻe kila ili, ka ʻili o ka mea hoʻoneʻe organik,
2. a laila e hoʻohana i nā mea hana e wehe ai i ka ʻōpala (puʻi uwea), e wehe i ka unahi hoʻokuʻu a i ʻole ke kiʻi ʻana, ka ʻōpala, ka ʻōpala wili, a pēlā aku.
3. ka hoʻohana ʻana i ka pickling.
Hoʻokaʻawale ʻia ʻo Galvanized i loko o ka plating wela a me ka plating anu, ʻaʻole maʻalahi ka palaka wela, ʻaʻole maʻalahi ka palaka.
Nā pilina ʻē aʻe o nā paipu alloy
Nā ʻano o nā paipu alloy
Kūleʻa kā mākou mau paipu kila kila i ka corrosion, ka wela a me ka oxidation, a hiki ke kū i ka hoʻohaʻahaʻa a i ʻole ke kū ʻole i ka ea a me ka oxidation.Hoʻohana pū ʻia kēia mau paipu kila kila i ka ʻoihana hoʻoheheʻe kemika no ka distilling tank, muffle furnaces, catalyst support grids, furnace baffles, pyrolysis operation pipes and flash dryer assemblies.
Hoʻopili ʻana i nā paipu hao
Hiki ke hōʻike ʻia a uhi ʻia paha nā paipu kila kila a hoʻopaʻa ʻia.E hoʻolako ʻia nā paipu a hiki i ka 3 "waho ke anawaena i loko o nā pūʻolo. No ka pale ʻana i ka ʻōpala i ka wā o ka hoʻouna ʻana, hiki ke hoʻopili ʻia nā puʻupuʻu o nā paipu kila maʻemaʻe ʻole i loko o nā pā polypropylene a hoʻopaʻa ʻia me nā ʻāpana kila pālahalaha.
