2. Flange da hatimi daidaitawa
Nau'in Flange: A cikin yanayin yanayi mai matsi, ana amfani da flanges na walda wuyan wuya (WNRF) ko flanges na haɗin gwiwa (IF), kuma an zaɓi wurin rufewa azaman mortise da tenon (TG) ko haɗin haɗin zobe (RJ) don rage haɗarin rufewar saman ƙasa.
Seling gasket: Zabi gasket na nannade karfe (tare da zoben ciki da na waje) (juriya na matsa lamba≤25MPa) ko octagonal karfe zobe gasket (high matsa lamba da high zafin jiki, matsa lamba juriya≥40MPa) bisa ga halaye na matsakaici. Kayan gasket ɗin ya dace da kayan bututu (kamar 316L gasket tare da flange 316L).
2,Tsarin Tsarin: Ƙarfafa Ƙarfafawa da Amincewa
1. Inganta tsarin injiniya
Ƙirar lanƙwasa: Guji lankwasawa daidai kuma yi amfani da babban radius mai lanƙwasa (R≥3D, D shine diamita na bututu) don rage yawan damuwa; Lokacin shimfida bututu masu yawa, ana rarraba su daidai gwargwado don daidaita ƙarfin radial.
Tsarin ƙarfafawa: Ƙara zoben tallafi (tazara≤1.5m) ko ginannen sandunan sakawa na tsakiya zuwa madaidaiciya madaidaiciyabututu mai dumama don hana nakasar jikin bututu a ƙarƙashin matsin lamba; Sashen haɗin da ke tsakanin flange da jikin bututu yana ɗaukar yanki mai kauri mai kauri (welding gradient tsagi) don haɓaka juriyar tsagewar kabu.
2. Hatimi da ƙirar haɗin gwiwa
Tsarin walda: Jikin bututu da flange suna shiga cikin walƙiya (kamar TIG waldi + filler waya), kuma ana yin gwajin 100% X-ray (RT) ko gwajin shigar azzakari cikin farji (PT) bayan walda don tabbatar da cewa kabu ɗin ba shi da pores da fasa;
Taimakon Faɗawa: An haɗa bututun musayar zafi zuwa farantin bututu ta amfani da tsari biyu na faɗaɗa hydraulic da walƙiya. Matsin fadada shine≥sau biyu matsi na aiki don hana matsakaicin yabo daga ramukan farantin bututu.
3,Tsarin masana'antu: tsananin kulawa da lahani da daidaito
1. Sarrafa daidaiton injina
A bututu sabon rungumi dabi'ar Laser / CNC sabon, tare da karshen fuska perpendicularity≤0.1mm; flange sealing surface roughness≤Ra1.6μ m, Kuskuren rarraba iri ɗaya na rami rami≤0.5mm, yana tabbatar da ƙarfi iri ɗaya yayin shigarwa.
Magnesium oxide foda cika: ta yin amfani da fasaha mai ƙarfi na girgiza, cike da yawa≥2.2g/cm³, don guje wa zafi na gida ko gazawar rufin da ke haifar da ɓarnawar sassan (juriya mai rufi≥100MΩ/ 500V).
2. Gwajin damuwa da tabbatarwa
Gwajin kafin masana'anta:
Gwajin Hydrostatic: Gwajin gwajin shine sau 1.5 na matsa lamba na aiki (kamar 10 MPa matsa lamba da matsa lamba na 15 MPa), kuma babu raguwar matsa lamba bayan riƙe tsawon mintuna 30;
Gwajin matsin lamba (wanda ya dace da kafofin watsa labarai na iskar gas): Matsalolin gwajin shine sau 1.1 na matsa lamba na aiki, haɗe tare da gano leak ɗin hallium mass spectrometry, tare da ƙimar ɗigo≤1 × 10 ⁻mbar· L/s.
Gwajin lalata: Ana amfani da samfur don gwajin bugun fashewa, kuma dole ne matsin fashewa ya kasance≥Sau 3 matsi na aiki don tabbatar da iyakar aminci.
4,Daidaita aiki: don jimre wa hadadden yanayin aiki
1. Diyya na fadada thermal
Lokacin da tsawonbututun dumama is ≥2m ko bambancin zafin jiki shine≥100℃, Ya kamata a shigar da haɗin haɗin haɓakar waveform ko sashin haɗin gwiwa mai sassauƙa don rama nakasar thermal ( adadin fadadawaΔ L=α L Δ T, kuα shine madaidaicin faɗaɗa madaidaicin kayan) kuma guje wa gazawar rufewar flange wanda ya haifar da matsananciyar bambancin zafin jiki.
2. Surface load iko
Hanyoyin watsa labaru masu girma (musamman gas) suna kula da zafi na gida kuma suna buƙatar raguwa a cikin nauyin ƙasa (≤8W/cm²). Ta hanyar ƙara lamba ko diamita nabututu mai dumamas, tarwatsa ƙarfin ƙarfi, da hana ƙima ko raƙuman abu (kamar nauyin saman≤6W/cm² lokacin dumama tururi).
3. Zane mai dacewa na Media
Don ruwan matsi mai ƙarfi mai ɗauke da barbashi/kazanta, allon tacewa (tare da daidaiton≥100 raga) ko murfin jagora yakamata a shigar dashi a mashigar bututun dumama don rage zaizayar kasa; Kafofin watsa labaru masu lalacewa suna buƙatar ƙarin jiyya na wucewa / fesa (kamar polytetrafluoroethylene shafi, juriya na zafin jiki).≤260℃).
5,Daidaitaccen tsari da ƙirar ƙira
Samar da rahotannin abu, cancantar tsarin walda (PQR), da rahotannin gwajin matsa lamba daidai da ka'idodin ƙasa (GB 150 "Tsarin Ruwa", NB/T 47036 "Electric Heating Elements") ko ka'idodin duniya (ASME BPVC, PED 2014/68/EU).
Don saduwa da buƙatun musamman na abokan ciniki (kamar dumama matsa lamba don API 6A kayan aikin rijiyar ruwa da dumama matsa lamba mai zurfi), muna haɗin gwiwa tare da abokan ciniki don daidaita yanayin aiki (kamar ƙayyadaddun ƙayyadaddun ƙayyadaddun ƙayyadaddun damuwa da haɓaka filin kwararar CFD) da keɓance ƙayyadaddun ƙayyadaddun flange (kamar flanges na musamman na zaren da sulfur resistant kayan).
taƙaitawa
Ta hanyar ingantaccen tsarin haɓakawa na " garantin ƙarfin kayan abu→ƙirar juriya na tsari→sarrafa daidaito masana'antu→gwaji da tabbatarwa rufaffiyar madauki", daflange lantarki dumama tube iya cimma abin dogara aiki a karkashin high ƙarfin lantarki yanayi. Mahimmancin shine don daidaita ƙarfin ɗaukar nauyin matsi, aikin rufewa, da kwanciyar hankali na dogon lokaci, yayin la'akari da halaye na matsakaicin abokin ciniki (zazzabi, lalata, yawan kwarara) don ƙirar da aka yi niyya, a ƙarshe saduwa da buƙatun aminci na ruwa / matsa lamba na iska.≥1.5 sau da sigogin ƙira.
