Stainless simbi yekushongedza simbi pombi
Stainless simbi yekushongedza pombi inonziwo Stainless steel welded simbi pombi, iyo inonzi welded pipe kwenguva pfupi.Kazhinji, simbi kana simbi tambo inosungirirwa mupombi yesimbi mushure mekudzvanywa uye kuumbwa neyuniti uye mold.Iyo nzira yekugadzira welded simbi pombi iri nyore, kugadzirwa kwakanaka kwakakwira, kune akawanda marudzi uye zvakatemwa, uye mutengo wemidziyo idiki, asi simba rakawanda rakaderera pane iro resimbi isina musono pombi.
Kune marudzi mazhinji emapombi esimbi isina tsvina, asi anonyanya kushandiswa kune zvinotevera zvinangwa:
1,Kurongeka kwepombi dzesimbi isina tsvina
1. Kurongwa nenzira yekugadzira:
(1) Pombi isina musono - pombi inodhonzwa inotonhora, pombi yakawedzera, pombi inokungurutswa.
(2) Welded pombi:
(a) Zvinoenderana nemaitiro ekugadzirisa - gasi yakadzivirirwa welding pombi, arc welding pombi, kuramba welding pombi (yakakwira frequency, yakaderera frequency).
(b) Yakakamurwa kuita yakatwasuka welded pombi uye spiral welded pombi zvinoenderana neweld.
2. Kurongeka maererano nechimiro chechikamu: (1) pombi yesimbi yakapoteredza;(2) Rectangular chubhu.
3. Kupatsanurwa nemadziro ukobvu - nhete yemadziro simbi pombi, gobvu madziro simbi pombi
4. Yakakamurwa nekushandiswa: (1) Mapombi ehurumende akakamurwa kuita mapaipi akatenderera, mapaipi ane rectangular uye mapaipi emaruva, ayo anowanzo shandiswa kushongedza, kuvaka, chimiro, nezvimwe;
(2) Pombi yeindasitiri: pombi yesimbi yepombi yemaindasitiri, pombi yesimbi yepombi yakajairika (pombi yemvura yekunwa), dhizaini chimiro / pombi yekutakura mvura, pombi yekupisa yekupisa, pombi yehutsanana yechikafu, nezvimwewo Inowanzoshandiswa munzvimbo dzakasiyana siyana dzeindasitiri. , senge petrochemical, bepa, simba renyukireya, chikafu, chinwiwa, mushonga uye mamwe maindasitiri ane zvakakwirira zvinodiwa zvemvura yepakati.
2,Seamless simbi pombi
Stainless simbi isina musono pombi imhando yesimbi refu ine mhango chikamu uye isina majoini akatenderedza.

2. Zvimiro zvesimbi isina musono pombi:
Hazvina kuoma kuona kubva pamusoro pekuita kuyerera: kutanga, iyo yakakura madziro emadziro echigadzirwa, iyo inowedzera hupfumi uye inoshanda.Iyo yakaonda iyo madziro ukobvu, iyo yakakwira mutengo wekugadzirisa uchave;Chechipiri, maitirwo echigadzirwa anosarudza zvaasingakwanisi.Kazhinji, kurongeka kwepombi yesimbi isina musono yakadzikira: kukora kwemadziro asina kuenzana, kupenya kwakaderera kwepasi mukati nekunze kwepombi, mutengo wakakwira, uye kune makomba nemavara matema pamusoro mukati nekunze kwepombi, izvo zvakaoma Bvisa;Chechitatu, kuonekwa kwayo uye kuumbwa kwayo kunofanira kugadziriswa pasina Indaneti.Naizvozvo, ine zvayakanakira mukumanikidza kwakanyanya, kusimba kwepamusoro uye michina yekugadzira zvinhu.
3,Welded simbi pombi
304 simbi isina tsvina yekushongedza chubhu
304 simbi isina tsvina yekushongedza chubhu
Welded simbi pombi, inodaidzwa kuti welded pombi kwenguva pfupi, ipombi yesimbi isina tsvina yakakandwa kubva mundiro yesimbi kana tambo yesimbi mushure mekushomerwa nekuumbwa nemuchina wakaiswa uye mold.

2. Zvinoumba welded simbi pombi:
Izvo hazvina kuoma kuona kubva pamusoro pekuita kuyerera: kutanga, chigadzirwa chinogadzirwa chinoramba chiripo uye online.Iko kukora kwemadziro, ndiko kuwedzera kwekudyara muyuniti nemidziyo yewelding, uye kushomeka kwehupfumi uye kunoshanda.Iyo yakatetepa madziro, iyo yakaderera yayo yekupinza-yekubuda reshiyo ichave;Chechipiri, maitiro echigadzirwa anotarisa zvakanakira uye zvazvakaipira.Kazhinji, pombi yesimbi yakashongedzwa ine hutsanana hwepamusoro, ukobvu hwemadziro hwakafanana, kupenya kwepamusoro kwemukati nekunze kwepombi yesimbi isina tsvina (iyo pombi yesimbi inopenya inotarwa negiredhi repamusoro rendiro yesimbi), uye inogona kuve yakasarudzika saizi.Naizvozvo, inomiririra hupfumi hwayo uye runako mukushandiswa kweiyo yakakwirira-chaiyo, yepakati-yakaderera pressure fluid.
Pane chlorine ion munzvimbo yekushandisa.Maion eklorini aripo kwakawanda, akadai semunyu, dikita, mvura yegungwa, mhepo yegungwa, ivhu, nezvimwewo. Simbi isina tsvina inoora nokukurumidza kana paine maion echloride, kunyange kudarika simbi yakaderera-kabhoni.Nokudaro, pane zvinodiwa zvekushandiswa kwezvakatipoteredza zvesimbi isina tsvina, uye zvakakosha kuipukuta nguva dzose kubvisa guruva uye kuichengeta yakachena uye yakaoma.
316 uye 317 Stainless steels (ona pazasi pezvivakwa zve317 Stainless steels) imolybdenum ine simbi isina tsvina.Iyo molybdenum iri mu317 simbi isina tsvina yakakwira zvishoma pane iyo mu316 simbi isina tsvina.Nekuda kwe molybdenum musimbi, kuita kwese kwesimbi iyi kuri nani pane 310 uye 304 simbi isina tsvina.Pasi pemamiriro ekupisa kwepamusoro, apo sulfuric acid yakaderera pane 15% uye yakakwirira kudarika 85%, 316 simbi isina tsvina ine zvakasiyana-siyana zvekushandisa.316 simbi isina tsvina zvakare ine yakanaka chloride corrosion resistance, saka inowanzo shandiswa munzvimbo dzemugungwa.Nekuvandudzwa kwehupfumi hwevanhu, kushandiswa kwepombi yesimbi isina tsvina kwave kuchiwedzera kufarirwa.Ichaunza shanduko itsva muminda yese.

316 pombi yesimbi isina tsvina
Simbi dzinoshandiswa petroleum, makemikari, zvekurapa, chikafu uye chiedza indasitiri
316 Stainless simbi pombi imhando yesimbi refu yakatenderedzwa simbi, iyo inoshandiswa zvakanyanya mumafuta, makemikari, ekurapa, chikafu, indasitiri yemwenje, michina yezviridzwa uye mamwe maindasitiri ekutapurirana mapaipi uye mekiniki zvimiro zvemukati.Uye zvakare, kana iko kupeta uye torsional simba zvakafanana, huremu hwakareruka, saka hunoshandiswawo zvakanyanya kugadzira mekiniki zvikamu uye zvimiro zveinjiniya.Inowanzoshandiswa kugadzira zvombo zvakasiyana-siyana, mbiya, mabhomba, nezvimwe.
Iyo yakanyanya kabhoni yemukati ye316 Stainless simbi pombi ndeye 0.03, iyo inogona kushandiswa mumaapplication uko annealing isingabvumirwe mushure mewelding uye yakanyanya kuomarara kuramba inodiwa.
316 uye 317 Stainless steels (ona pazasi pezvivakwa zve317 Stainless steels) imolybdenum ine simbi isina tsvina.
Kuita kwese kwesimbi iyi kuri nani pane 310 uye 304 simbi isina tsvina.Pakupisa kwepamusoro, kana huwandu hwe sulfuric acid huri pasi pe15% uye yakakwirira kudarika 85%, 316 simbi isina tsvina ine zvakawanda zvekushandisa.
316 Stainless simbi ndiro, inozivikanwawo se 00Cr17Ni14Mo2, corrosion resistance:
Kupokana necorrosion kuri nani pane 304 simbi isina tsvina, uye ine yakanaka yekurasa kuramba mukugadzirwa kwe pulp nebepa.
Iyo carbide precipitation resistance ye316 Stainless simbi iri nani pane iya ye304 Stainless simbi, uye tembiricha iri pamusoro inogona kushandiswa.
Mhando: 316 Stainless simbi machubhu, 316 Stainless simbi inopenya machubhu, 316 Stainless simbi yekushongedza machubhu, 316 Stainless simbi capillary chubhu, 316 Stainless steel welded chubhu, 304 Stainless simbi machubhu.
Iyo yakanyanya kabhoni yemukati ye316L Stainless simbi pombi ndeye 0.03, iyo inogona kushandiswa mumashandisirwo apo annealing isingabvumirwe mushure mewelding uye yakanyanya kuomarara kuramba inodiwa.
