Weld dahaaran Flange

A alxanka dahaadhkawaa flange foojari ah oo leh daxal -lakabka daawaha u adkaysta oo lagu shubay dareeraha{1}}oogga xidhiidhka alxanka. Flange salku waxa uu xanbaarsan yahay culayska culayska iyo xoog saarista, halka lakabka dusha sare ee CRA uu ka ilaalinayo boodhka, wejiga xidhidhiyaha, jeexjeexa RTJ, kala guurka qoorta, ama meelaha kale ee qoyan ee ka imanaya warbaahinta daxalaysa.

Qaab dhismeedkan waxaa loo isticmaalaa marka birta kaarboonka caadiga ah ama flange birta daawaha hoose ay leedahay awood farsamo oo ku filan, laakiin dhinaca geedi socodka waxay u baahan tahay iska caabin daxalka adag. Xaaladaha adeegga caadiga ah waxaa ka mid ah gaaska dhanaan, CO₂- gaas ka kooban, duritaanka biyaha badda, biyaha la soo saaray, koloriin{2}} dareereyaal sidda, warbaahinta sifaynta, khadadka habka batroolka, iyo isku xirka dhuumaha xeebaha.

Marka la barbar dhigo flange daawaha adag, dahaadhka alxanka ayaa u oggolaanaya mashruuca inuu isticmaalo daxalka{0}daawaha u adkaysta kaliya dusha xidhiidhka loo baahan yahay. Tani waxay gacan ka geysaneysaa in la xakameeyo qiimaha alaabta iyadoo la ilaalinayo jirka flange inuu ku filan yahay heerka cadaadiska loo baahan yahay. Qalabka birta ee Octalalxan ku dahaadhay garabyo been abuur ahluqunta alxanka, indho la'aanta, RTJ, simbiriirixan{0}}, iyo sawir caadadii{1}noocyo ku salaysan, oo ay ku jiraanAlloy 625 / Inconel 625 Weld dahaaran Flange, Alloy 825, 316L, 904L, bir duplex ahama, iyo super duplex ahama daalacashada fursadaha.

Daboolka alxanka ku dahaaran waxa laga dhisay laba hab oo walxeed. Been abuurka salku waxa uu bixiyaa xooga farsamada, qiimaynta cadaadiska, joomatari flange, iyo xasiloonida bolting. Maaddada daboolan waxay bixisaa iska caabbinta daxalka dhinaca qoyan.

Alaabooyinka aasaasiga ah ee caadiga ah waxaa ka mid ah ASTM A105 ee birta kaarboonka caadiga ah ee flanges been abuur ah, A350 LF2 ee hooseeya{3} adeegga heerkulka, A694 F52 / F60 / F65 / F70 ee sare{9}}nidaamka gudbinta cadaadiska, iyo A182 darajooyinka ee birta alloy, birta ahama, duplex, ama super shuruudaha duplex forged.

Daawaha dulsaarka CRA waa in lagu doortaa iyadoo loo eegayo habka dhexdhexaadka ah ee dhabta ah. Qiimaha kaligiis maaha saldhig doorasho oo badbaado leh. H₂S, CO₂, fiirsashada chloride, heerkulka shaqaynta, cadaadiska, ka kooban biyaha, pH, oksijiinta soo galitaanka, iyo walxaha tuubooyinka isku xidhan ayaa dhamaantood saamayn kara doorashada walxaha ugu dambeeya.

Waayodahaarka alxanka ee flangeMashaariicda, daaha dahaadhka ah waa in sidoo kale la mid ah qaybta ku xiran. Haddi baalku ku xidhmo tuubo xidhan, CRA -tuubo dahaaran, tuubo dulsaaran, daxal - waalka adkaysi u leh, spool, ama manifold, soohdinta dulsaaran waa in dib loo eego si birta kaarboonka ee aan la ilaalin aanay u soo gaadhin jidka socodka.

Meesha la dulsaaray maaha tafaasiil yar. Waxay go'aaminaysaa kharashka, gunnada mishiinada, baaxadda baadhista, iyo haddii baalku si dhab ah u ilaalin karo dusha qoyan. Warqadda wax iibsiga ee odhanaysa "CRA dulsaar baa loo baahan yahay" badanaa kuma filna. Sawirku waa inuu muujiyaa sida saxda ah meesha lakabka alxanka loo baahan yahay.

Garabada alxanka ee RTJ waxay u baahan yihiin fiiro gaar ah. Meesha giraantu waa meel daboolan, ma aha oo kaliya muuqaal la farsameeyay. Daboolida ka dib iyo farsamaynta kama dambaysta ah, jeexdintu waa in laga hubiyaa cabbirka, xaaladda dusha sare, natiijada PT, iyo dhumucda dulsaarka hadhay ee hadhay.

Dhinacyada wejiga kor u kacaya, aagga xidhiidhka gaaskutka waa in la xakameeyaa ka dib marka la wajaho. Lakabka CRA ee siman ee aragga ah kuma filna haddii daboolidda wejiga fidsanaanta, dhammaynta, ama dhumucda mashiinka ka dib aanu buuxin shuruudaha sawirka.

Wax soo saarka eealxan ku dahaadhay garabyo been abuur ahwuu ka duwan yahay mashiinada flange ee caadiga ah. Nidaamku waa inuu tixgeliyo milanka alxanka, gunnada mishiinada, kiimiko kama dambaysta ah, iyo xidhitaanka joomatari oogada isku mar.

Dariiqa wax-soo-saarka wax-soo-saarka caadiga ah waxaa ku jira tillaabooyinka soo socda:

1. Dib u eegis been abuur ah
Qalabka jirka ee flange, nambarka kulaylka, heerka been abuurka, heerka cadaadiska, nooca wejiga, iyo MTC waa la hubiyaa ka hor intaysan bilaabin shaqada dusha sare. Talaabadani waxay xaqiijinaysaa in flange-ga salku laftiisu uu ku habboon yahay nidaamka iibka iyo sawirka mashruuca.

2. Xaqiijinta gunnada aagga iyo mashiinada dulsaar{1}}
Diirada, wejiga kor u kaca, jeexdin RTJ, wejiga gudaha ee indho la'aanta, wareejinta qoorta, ama meelaha kale ee qoyan ayaa dib loogu eegay sawirka. Gunnada mashiinada oo ku filan waa in la qorsheeyaa si ay dusha ugu dambeeya ee mishiinadu u sii haysato lakabka CRA ee loo baahan yahay.

3. WPS / PQR iyo diyaarinta birta buuxinta
Habka dulsaarka alxanka, biraha buuxinta, habka alxanka, kala duwanaanta gelinta kulaylka, isku xigxiga lakabka, iyo u qalmida alxanka waa in la diyaariyaa ka hor wax soo saarka. Tani waxay si gaar ah muhiim ugu tahay Alloy 625, Alloy 825, duplex, iyo super duplex work overlaying.

4. Dhigista alxanka ee CRA
Lakabka CRA waxaa dhigaa alxanayaal u qalma ama hawl-wadeennada alxanka. Dusha sare -lakabyo badan ayaa badanaa la isticmaalaa sababtoo ah lakabka koowaad waxaa lagu qasi karaa birta salka. Aqbalaada kama dambaysta ah waa in lagu saleeyaa dusha sare ee la dhammeeyey ka dib mashiinka.

5. Nadiifinta dhexdhexaadka ah iyo xakamaynta muuqaalka
Nadiifinta inta u dhaxaysa baasaska waxay caawisaa in laga fogaado dhididka, wasakhowga, isku-dhafka la'aanta, iyo cilladaha dusha sare. Tallaabadani maaha shaqo qurxin; waxay inta badan go'aamisaa in kormeerka PT dambe uu si nadiif ah u gudbi doono iyo in kale.

6. Dib u eegis PWHT markii loo baahdo
Qaar ka mid ah walxaha salka ama qeexida mashruuca ayaa laga yaabaa inay u baahdaan daawaynta kulaylka dambe- PWHT waa in dib loo eego ka hor wax soo saarka sababtoo ah waxay saameyn kartaa adkaanta, xakamaynta cabbirka, iyo qorshaha kormeerka ugu dambeeya.

7. Makiinada qallafsan iyo farsamaynta kama dambaysta ah
Alxanka dahaadhka ka dib, flange-ga waxa lagu farsameeyay biyihii u dambeeyay, soo jeeda, jeexdin RTJ, dalool bool ah, iyo cabbir xidhidh. Tani waa meesha wax soo saarka taxadar la'aanta ah ay ka saari karto waxyaabo badan oo CRA ah. Dhumucda dusha sare ee ugu yar ee dhammaatay waa in wali la ilaaliyaa marxaladan ka dib.

8. Kormeerka ugu dambeeya iyo dib u eegista dokumentiga
PT, PMI, qallafsanaanta, ferrite, kormeerka cabbirka, iyo hubinta dhammaystirka dusha sare ayaa loo sameeyaa si waafaqsan shuruudaha mashruuca. Warbixinnada waa in lagu wanaajiyaa calaamadaynta flange, lambarka kulaylka, iyo liiska baakadaha ka hor intaan la dhoofin.

Si aad u hesho sharraxaad farsamo oo ballaadhan oo ku saabsan habka dahaadhka alxanka ee guud ahaan tuubooyinka, flange iyo alaabta saxanka, arag ourhagaha dahaadhka alxanka.

Dulmanka alxanka, kormeerku waa inuu caddeeyaa laba shay: garabka salku waa buuxiyaa shuruudaha farsamada iyo cabbirka, iyo dulkaynta CRA waxay la kulmeysaa daxalka{0}} shuruudaha adeegga. Haddii labada dhinacba daciif yihiin, garabka ayaa laga yaabaa inuu ku guuldareysto aqbalaadda mashruuca.

PMI ka dib mashiinkagaar ahaan waa muhiim. Haddii PMI kaliya la sameeyo ka hor mashiinka kama dambaysta ah, waxaa laga yaabaa inaysan si buuxda u matalin dusha sare ee la xiriiri doona dhexdhexaadiyaha habka. Wixii dhanaan ah ama koloridhida{2}}adeegga xanbaarsan, dusha sare ee CRA ee mashiinka lagu farsameeyey waa meesha ugu muhiimsan.

Shixnadaha dhoofinta, isbarbardhigga dukumentiga waa qayb ka mid ah ilaalinta tayada. Nambarka kulaylka, shahaadada alaabta salka, dahaadhka dahaadhka, warbixinta PMI, warbixinta PT, liiska baakadaha, iyo calaamadaynta flange waa inay si cad isugu xidhmaan. Tani waxay yaraynaysaa halista helitaanka dib u dhaca kormeerka ee ay sababto diiwaanada maqan ama iswaafaqsan.

Garaafka alxanka ee dulsaaran waxa loo isticmaalaa halka jidhka garabku u baahan yahay xooga cadaadiska caadiga ah, laakiin dareeraha - oogada xidhiidhka waa in ay iska caabiso daxalka gaaska dhanaan, chloride{1}} biyaha qaada, biyaha badda, warbaahinta aashitada ah ama dareerayaasha habka gardarada leh. Si ka duwan sida caadiga ahalxanka on flangeinta badan loo xushay isku xirka tuubada iyo heerka cadaadiska, alxanka dahaadhka ah waa inuu sidoo kale xakameeyaa oogada CRA ee soo shaacbaxday dhexdhexaadka.

• Soo saarista gaasta dhanaan iyo nidaamyada ururinta

H₂S{0}}adeegga ka kooban, jidhka flange wuxuu u baahan karaa birta kaarboon ama birta daawaha hooseeya, halka dusha qoyan uu u baahan yahay ilaalinta CRA. Alloy 625 dulsaar ayaa caadi ahaan dib loogu eegaa adeega noocan ah. Xakamaynta adkaanta, xaalada HAZ, iyo shuruudaha NACE MR0175 / ISO 15156 waa in la hubiyaa ka hor wax soo saarka.

• duritaanka biyaha badda oo soo saaray khadadka biyaha

Biyaha badda iyo biyaha la soo saaray waxaa laga yaabaa inay ku jiraan chlorides, gaas kala diri, ciid, miisaan iyo darawallada kale ee daxalka. Daboolan, daboolka wejiga oo kor u kaca iyo daboolka wareejinta qoorta ayaa kaa caawinaysa yaraynta khatarta birta kaarboonka ee soo shaac baxday dareeraha{1}}aagga xidhiidhka.

• Isku xirka badda iyo badda hoosteeda

Mashaariicda xeebaha ka baxsan inta badan waxay u baahan yihiin kormeer adag iyo dukumeenti. jeexjeexyada RTJ, wejiyada gaasaska, isku xirka kala duwan, isku xirka valves iyo isku xirka is haysta ayaa laga yaabaa inay u baahdaan PMI, PT, tijaabinta adkaanta, tijaabinta ferrite, kormeerka cabbirka iyo dhibcaha marqaati saddexaad{1} xisbiga.

• Sifeynta iyo khadadka habka petrochemical

Warbahinta habka aysiidhka ah, koloriin{0}ka kooban dareere, heerkulbeegyo sareeya{1}iyo bay'ada daxalka isku dhafan waxa laga yaabaa inay u baahdaan ilaalinta CRA ee dusha qoyan. Duubka alxanka ayaa u oggolaanaya mashruuca inuu isticmaalo cadaadiska caadiga ah - jirka flange sidda isagoo hagaajinaya iska caabinta daxalka halkaasoo dhexdhexaadiyuhu dhab ahaantii la xiriiro qaybta.

• Dhuumaha daboolan, CRA -tubbada safan iyo isku xirka kala duwan

Albaabada alxanka ee dahaadhka ah waxaa inta badan lagu isticmaalaa tuubo xidhan, CRA{0}tuubo dahaaran, tuubo daboolan alxanka, alxanka, dabaasha iyo kala duwanaanta. Meesha dulsaarku waa inay la socotaa qaybta ku xidhan si daxalka{2}} u ahaado mid joogto ah.

Octal Steelwaxay taageertaa habkan laga soo bilaabo dib u eegista walxaha ilaa sii deynta shixnadaha. Waxaan ka caawineynaa isku toosinta darajada flange-ga salka, dahaadhka dahaadhka, dhumucdii daboolka dhammaatay, nooca wejiga, shuruudaha jeexdin ee RTJ, iyo baaxadda baadhista ka hor inta aan la bilaabin wax-soo-saarka, markaa flange-ga la keenay way fududahay in la xaqiijiyo marka la helayo kormeerka.

Faa'iidadayadu maaha oo kaliya saadka sahayda, laakiinisuduwidda mashruuca: soo saarista flange been abuur ah, xakamaynta dulsaarka CRA, mashiinada kama dambaysta ah, PMI / PT / kormeerka adkaanta, taageerada kormeerka xisbiga saddexaad, iyo diyaarinta dukumeenti dhoofinta waxaa lagu maareyn karaa hal silsilad sahay ah. Tani waxa ay yaraynaysaa halista alaabta is-daba-marin, xad-dhaaf aan caddayn, warbixinnada maqan, ama xidhitaanka{2}} waxyeellada wejiga ka hor inta aan la rarin.

Dalabka dhoofinta, Octal Steel waxa kale oo ay fiiro gaar ah u siinaysaa xidhidhaynta ilaalinta sagxadaha mishiinada, godadka RTJ, wejiyada kor u kaca, godadka boodhka ah, iyo calaamadaynta flange, ka caawinta flange-ga inay la yimaadaan xaalada badeecada iyo xidhmada dukumeentiga labadaba diyaar u ah dib u eegista mashruuca.
