Chii chinonzi Inconel 625 Seamless Pipe?

Inconel 625 (UNS N06625, W.Nr. 2.4856) imhando ye nickel-chromium-molybdenum alloy ine niobium yakawedzerwa. Niobium inoshanda ne molybdenum kusimbisa matrix ye alloy, ichiipa simba rakawanda pasina kuda kurapwa kwakasimba kwekupisa. Izvozvo inyaya huru - zvinoreva kuti unogona kuisanganisa asi uchiwana simba rakazara pasina kurapwa kwekupisa mushure mekuisanganisa.

Pombi isina musono zvinoreva kuti hapana musono wakasungirirwa pahurefu hwayo. Inogadzirwa nekuboora billet yakasimba woitenderedza kana kuidhonza kuti ikwane saizi yayo. Kusabatanidzwa kwemusono kunoreva kuti hapana nzvimbo isina simba, hapana njodzi yekuora kwemusono, uye kusimba kuri nani pakumanikidzwa. Ndosaka mapaipi asina musono ari sarudzo yekutanga yekushandiswa kwakakosha uko kukundikana kusiri sarudzo.

Pombi yeInconel 625 isina musono inoshanda kubva pakupisa kwe cryogenic kusvika ku982°C (1800°F). Inodzivirira kupwanyika kwegomba, ngura, uye crucide stress corrosion — zvinhu zvitatu zvinouraya mapaipi esimbi asingatsvi mumabasa emugungwa nemakemikari.

Kuumbwa kweMakemikari

Kuumbwa kwayo ndiko kunoita kuti Inconel 625 ishande zvakanaka. Heino kupatsanurwa kwakaitwa:

Chinhu	Kurema %
Nickel (Ni)	58.0% miniti (yakaenzana)
Chromium (Cr)	20.0 – 23.0%
Molybdenum (Mo)	8.0 – 10.0%
Niobium + Tantalum (Nb + Ta)	3.15 – 4.15%
Simbi (Fe)	5.0% yakakwira
Manganese (Mn)	0.50% yakakwira
Silikoni (Si)	0.50% yakakwira
Kabhoni (C)	0.10% yakakwira
Cobalt (Ko)	1.0% yakakwira

Nickel yakawanda (58%+) ndiyo inoita kuti isanyanya kukanganiswa nekuora kwechloride. Molybdenum (8-10%) inoita kuti irambe yakasimba mukuora kwegomba uye mumipata mumvura yegungwa uye ine chloride. Niobium (3.15-4.15%) inosimbisa mhinduro yakasimba.

Zvivakwa zveMichina

Kana yaiswa muchina, Inconel 625 pipe isina musono inopa zvinotevera:

Pfuma	Kukosha
Simba Rokusimba (Rekupedzisira)	≥827 MPa (120 ksi)
Simba reGoho (0.2% kuderedzwa)	≥414 MPa (60 ksi)
Kureba (mu 2″)	≥30%
Kuoma	≤287 HB
Kuwanda kwevanhu	8.44 g/cm³
Nzvimbo Yokunyunguduka	1290 – 1350°C

Izvi zvinorevei mukuita:Inconel 625 yakasimba zvakakwana kuti ikwanise kushandisa mapaipi ane simba rakawanda uye yakasimba zvakakwana kuti irambe yakarova kana kudedera. Kureba kwe30% kunoreva kuti inogona kukotama uye kugadzirwa pasina kutsemuka.

Pakupisa kwakanyanya, Inconel 625 inochengetedza simba rayo kusvika ku982°C (1800°F). Inogara zvakanaka pakupisa kwe cryogenic — kusvika ku -196°C — isingaome, ndosaka uchiiona mu LNG uye liquid nitrogen systems.

Kuramba Kuora — Kwakunonyatsopenya

Ichi ndicho chikonzero chikuru chinoita kuti vanhu vabhadhare mari yeInconel 625. Inobata nharaunda dzinoparadza simbi isingasvibi ye316L mumwedzi yakati wandei.

Mvura yegungwa nenzvimbo dzegungwa:Inconel 625 haina ngura mumvura yegungwa. Inodzivirira ngura, ngura yakatsemuka, uye biofouling. Ndosaka uchiiona mumapaipi ekutonhodza mvura yegungwa, masisitimu emvura yemoto, mapaipi emvura e ballast, uye michina yekugadzira pasi pegungwa.

Kupwanya kwe chloride stress corrosion:Izvi ndizvo zvinonyanya kukosha pakugadzira simbi isingasvibi 304 ne316 mumabasa emugungwa nemakemikari. Inconel 625 haina simba rakawanda nekuda kwehuwandu hwayo hwe nickel.

Kuramba asidhi:Inconel 625 inobata sulfuric acid, hydrochloric acid, phosphoric acid, mixed acids, chlorine, chlorinated solvents, fluorides, uye strong alkalis. Mu hydrofluoric acid vapor, corrosion rate ye316L stainless steel inogona kunge yakapetwa ka65 pane Inconel 625.

Kuramba kukanda:PREN (Pitting Resistance Equivalent Number) yeInconel 625 yakakwira zvakanyanya kupfuura 316L. Mu10% FeCl₃ solution pa65°C, 316L inodonha zvakanyanya nepo Inconel 625 isingakanganiswe zvachose.

Basa reSour (H₂S):Inconel 625 inotenderwa kushandiswa sevhisi yesour sekureva kweNACE MR0175 / ISO 15156. Inoshandiswa zvakanyanya mukugadzirwa kwemafuta negesi mugungwa kune zvikamu zvinosangana nehydrogen sulfide, carbon dioxide, uye chlorides.

Mafomu eChigadzirwa neMaitiro

Inconel 625 inowanikwa mumhando dzakasiyana dzezvigadzirwa. Womic Steel inopa zvese izvi:

Pombi neChubhu Zvisina Musono:ASTM B444 / ASME SB-444, AMS 5581

Maitiro Ekugadzira

Womic Steel inogadzira pombi isina musono yeInconel 625 kuburikidza nenzira inodzorwa:

Kunyunguduka:Kunyungudutsa kwevacuum induction (VIM) kana kuti vacuum arc remelting (VAR) kunoita kuti pave negasi shoma uye kuchena kwakanyanya.
Kuboora:Chidimbu chakasimba chinodziiswa uye chinoboorwa kuti chiite goko risina chinhu.
Kupisa kana kutenderedza:Goko rine mhango rakaderedzwa kusvika pahukuru hwepakati.
Mufananidzo unotonhora:Kudhirowa kwakawanda kunotonhora ne intermediate annealing kunoita kuti zvive nyore uye zvinokwanisa kushivirirana zvakanaka. Kudhirowa kwakadzika kunovandudza kupenya kwenzvimbo uye kururama kwenzvimbo.
Kugadzirisa mhinduro:Kupisa kwekupedzisira pa980-1040°C kunoteverwa nekutonhodza nekukurumidza kunodzorera kuramba ngura uye kugona kwayo kupora.
Kunyungudutsa uye kunonoka:Inobvisa makomba ne oxide, ichisiya nzvimbo yakachena isina chinhu.
NDT uye kuyedzwa:Kuyedzwa kwehydrostatic 100%, kuyedzwa kwe ultrasonic, kuyedzwa kwe eddy current, uye kuyedzwa kwe dimensional.

Pamapaipi akasungirirwa, maitiro acho anoshandisa strip yakaputirwa yakaumbwa uye yakasungirirwa uchishandisa TIG kana plasma welding, ichiteverwa ne full solution annealing uye NDT ye weld seam.

Kushongedza uye Kugadzira

Inconel 625 inozivikanwa nekugona kupinza zvinhu zvakanaka. Unogona kuibatanidza uchishandisa TIG (GTAW), MIG (GMAW), stick welding (SMAW), laser welding, kana electron beam welding.

Simbi yekuzadza inokurudzirwa:AWS A5.14 ERNiCrMo-3 (Inconel 625 filler)

Pfungwa huru dzekurangarira:

Hapana mushonga wekupisa mushure mekuwedhwa unodiwa — chiumbwa ichi chinowana simba racho kubva mukusimbaradzwa kwemvura yakasimba, kwete kubva mukuoma kwemvura.
Chenesa nzvimbo yekuwedera zvakanaka usati wawedera — pasina mafuta, girizi, kana oxide.
Dzora simba rekupisa kuti usanyanya kupisa.
Chengeta tembiricha yepakati penzira iri pasi pe150°C.
Shandisa gasi rekudzivirira reargon kana argon-helium.

Pakusanganisa simbi dzakasiyana (Inconel 625 kusimbi isingatsvi kana kusimbi yekabhoni), ERNiCrMo-3 ndiyo inokurudzirwawo kuzadza.

Simbi Isina Kushanda Inconel 625 vs 316L — Kuenzanisa Kunokurumidza

Uyu mubvunzo watinogara tichiubvunza. Heino pfupiso:

Chikamu	Inconel 625	316L Simbi Isina Kusimba
PREN (kuramba kupinza makomba)	≥45	24-26
Tembiricha yepamusoro yebasa	982°C (1800°F)	~400°C
Kudzivirira kweChloride SCC	Zvinenge zvisina dziviriro mumuviri	Zvinokanganisa
Kuora kwemvura yegungwa	Zvakanakisa	Zvisina kunaka (zvinokasira kudonha)
Simba rekupa (rakabviswa)	≥414 MPa	~170 MPa
Mutengo wepakati	Yakakwirira	Zvakaderera
Kugona kusundira	Zvakanaka kwazvo, hapana PWHT	Zvakanaka, zvingada PWHT

Munzvimbo dzine hydrofluoric acid, 316L inogona kuora nekukasira kanosvika makumi matanhatu neshanu kupfuura Inconel 625. Mumvura yegungwa, makomba e316L mukati memwedzi. Inconel 625 inogara kwemakumi emakore.

Zvinhu Zvinokonzera Mutengo neKudhura kweInconel 625

Kubva muna 2025, mitengo yeInconel 625 inowanzo tangira pa$45 kusvika $85 pa kg, zvichienderana nechimiro chechigadzirwa, huwandu, chitupa, uye mutengesi:

Fomu reChigadzirwa	Mutengo Unofungidzirwa (USD/kg)
Sheet / Plate	$45 – 65
Bhawa redenderedzwa	madhora makumi mashanu kusvika makumi manomwe
Pombi/Chubhu Isina Musono	$55 – 75
Waya	madhora makumi matanhatu kusvika makumi masere nemashanu (60 – 85)

Chii chinonyanya kukanganisa mutengo:

Zviri muNickel (~58%) — mitengo inotevedza misika yeLME nickel
Nzira yekugadzirisa — yakagadzirwa, yakaputirwa nemoto, kana yakaputirwa nechando
Zvinodiwa zvechitupa — ASTM, ASME, NACE, kana imwe kambani yekuongorora inowedzera mari
Huwandu hweodha — maodha akawanda anoderedza mutengo wepa-kg
Kwakatangira — Zvinhu zvemuUS/EU zvinowanzodhura kupfuura zvakagadzirwa neChina
