ASTM A106 Seamless Pipe

ASTM A106 ndiyo yakajairwa seamless kabhoni simbi pombi vagadziri vazhinji vanotsanangura kana mutsara uchifanira kutakura mvura inopisa kana gasi pasi pekumanikidzwa. Yakagadzirirwa kukwirisa-sevhisi yekupisa, ine dimensioning maringe neASME B36.10M, uye inogona kupihwa migumo yakapfava kana kuti yakabhenda yewelding, kukotama uye kuchinjika. Pakati peMagiredhi A, B uye C muASTM A106, Giredhi B rinonyanya kushandiswa nekuti rinopa musanganiswa wakavimbika wesimba, ductility uye weldability yemitsara yemhepo, misoro yekunatsa, pombi yekugadzira uye magetsi emagetsi maseketi.

• Chiyero: ASTM A106 / ASME SA106
• Giredhi: B (inowanikwawo A, C kana purojekiti ichibvumira)
• Fomu: isina musono, inopisa-yapera kana kutonhora-yapera
• Inopera: Plain end (PE) kana beveled magumo (BE) yewelding
• Zviyero: ASME B36.10M, NPS nehurongwa-zvichienderana

Giredhi rinobva pakugadzirwa kwakapfava,{0}kunodzorwa zvakanaka kabhoni-manganese-silicon. Kudzora kweP uye S kunochengeta pombi ichigoneka uye yakaoma.

Nei izvi zvichikosha: kabhoni inopa giredhi simba rayo; manganese inobatsira kudzikamisa chimiro cheferrite-pearlite uye inovandudza kuoma; silicon inonatsiridza chikero/oxidation kuramba kana pombi yakatakura chiutsi chinopisa kana process media.

Giredhi B ndiro "giredhi repakati" asi rakatosimba zvakaringana kune akawanda mashandisirwo ezvirimwa.

Dudziro yekugadzira nekugadzira: tensile simba rinodzivirira kubva pakuputika uye axial mitoro; goho simba ndiro muganhu pamberi pekushanduka zvachose, kunyanya kukosha kune yakakwirira{{0}kumhanya kwemhepo; kurebesa kunoita kuti pombi igone kuve munda-yakakombama, yakakwenenzverwa nekuiswa pasina kutsemuka.

Kuita muSevhisi-Yekupisa Kwepamusoro
A106 Giredhi B inoitirwa kuti irambe iri musevhisi patembiricha yesimbi inosvika ku400–450℃bhendi. Panhanho iyi ferrite-pearlite microstructure inoramba yakatsiga, silicon inobatsira pamusoro kuti isakwira, uye pombi inoramba ichimanikidza{4}kukwanisa kutakura. Ndosaka yakatsanangurirwa mitsara yekudyira kwebhailer, misoro yehutsi, kupisa-pombi dzekuchinjana, sevhisi yemafuta anopisa uye masisitimu ekuchenesa. NePWHT yakakodzera uye maitiro ekushongedza, pombi inogona zvakare kumhanya musevhisi yecyclic pasina kurasikirwa nekukurumidza kwekuoma.

YeA106 Giredhi B nzira yekugadzira haisi yekuwedzera - ndicho chikonzero iyo pombi inogona kunyatsoshanda pakupisa kwakanyanya uye kudzvanywa. Iyo yakajairwa chigayo nzira isina musono A106 Giredhi B paOctal Pipe inoita seizvi:

1. Billet kusarudzwa uye chemistry control
Kugadzirwa kunotanga kubva pakufa (kunyatso deoxidized), yakanaka-grain carbon steel billets zvinotoenderana neA106 chemical range. Izvi zvinovimbisa yakaderera P uye S, kuchena kwakanaka uye weldability. Kupisa kunotariswa kusati kwakunguruka kuitira kuti michina yeGiredhi B inokwanisa kusvikirwa mushure mekugadzira uye kurapwa kupisa.

2. Billet kupisa
Mabhari anodziiswa muchoto chinotenderera kana kufamba-padanda kusvika pakuboora/kukunguruka. Kudziisa kwakafanana kwakakosha pano nekuti tembiricha isina kuenzana inogona kukonzera madziro-kusiyana kweukobvu kana billet raboorwa.

3. Kuboora kupisa (hollow making)
The hot billet inobayiwa pamuchinjiko- kana mandrel piercing mill kuita goko risina mhango. Apa ndipo panotendeuka pombi kubva padenderedzwa rakasimba kuita chubhu isina musono. Chinangwa ndechekugadzira shell isina kuputika kwepakati uye ine kunyange madziro akatenderedza denderedzwa.

4. Elongation uye plug/mandrel rolling
Goko rine mhango rinobva rarebeswa uye rokungurutswa pamusoro pemandrel kana plug mill kuti isvike pedyo nedhayamita yakarongerwa uye ukobvu hwemadziro. Mamiriro akati wandei ekutenderedza anogona kushandiswa kukwenenzvera madziro uye kugadzirisa pamusoro. Iyi nhanho ndiyo kiyi yekuita kuti mukati memukati utsvedze uye nekuchengetedza madziro ukobvu mukati mekushivirira.

5. Kukura/kudzikisa chigayo
Chigayo chekuyera kana kudzikisira chinounza pombi kune yayo yekupedzisira OD uye kutenderera. Kune akakwira masheti (akasimba madziro), rolling parameter inogadziriswa kuchengetedza concentricity. Kunyatsoita saizi pano zvinoreva kuti zviri nyore kupinza uye kukwana zviri nani-panzvimbo.

6. Kutonhora uye kururamisa
Mushure mekushanda kunopisa, mapaipi anotonhodzwa nenzira inodzorwa uye ozopfuura nemuchina wekururamisa. Kutwasuka kwakakosha kune dzakafanogadzirwa spools uye kune otomatiki welding.

7. Kurapa kwekupisa (sezvinodiwa)
Zvichienderana nekukura kwepombi, reshiyo yekuderedza uye zvinodiwa nemutengi, mapaipi anogona kugadzirwa kana kuti stress-kusunungurwa.

Normalizing inonatsa iyo ferrite-pearlite chimiro, inofananidzira zvivakwa pamwe nehurefu uye inovandudza kuoma.

Kunyaradza kushushikana kunobvisa kuumba kushushikana, uko kunobatsira kana pombi ichizoiswa musystem inozoona kuchovha bhasikoro.
Iyi inodzorwa kupisa kurapwa ndiyo inobatsira A106 Giredhi B kuchengetedza ductility uye kukanganisa kuramba mubasa rinopisa.

8. Kupedzisa, NDE uye hydrotest
Mapombi akapedzwa anochekwa kusvika pakureba, migumo yakatarisana/yakakomberedzwa, uye hurefu hwega hwega hunoongororwa nemeso ekuona kwepamusoro uye kwedimensional kurongeka. Ipapo pombi inoedzwa:

• hydrostatic bvunzo kuratidza kudzvanywa kwemukati
• eddy{{0}yazvino kana ultrasonic NDE yekutsvaga mukati/pamusoro pezvakaremara
• kutara uye kuvhara / varnish yekudzivirira
• Chete mushure mematanho ese aya ndipo pombi inoburitswa neMTC.

Nekuda kwekuti nzira yese haina musono (hapana longitudinal weld), pombi ine yunifomu yekumanikidza kutenderedza denderedzwa rakazara - chikonzero chikuru A106 inosarudzwa pamusoro pepombi yakashongedzwa kuitira{1}}tembiricha yepamusoro.

(yakajairika kupa, inogona kutevera chikumbiro cheprojekiti)

Kuita kuti pombi igamuchirwe kumanikidza uye sevhisi inopisa, ASTM A106 inoreva izvo zvinodikanwa muASTM A999. Octal Pipe inogona kupa iyo yakazara nzira yekuyedza:

• Hydrostatic bvunzo pahurefu hwega hwega kuratidza kudzvanywa
• Nondestructive bvunzo (eddy yazvino kana ultrasonic) kuratidza kumusoro uye kukanganisa kwemukati
• Tensile uye kuoma bvunzo pakupisa kwesimbi kuratidza kutevedza kwemichina
• Kufuratira / kubhenda bvunzo kuratidza ductility
• Visual, OD, madziro uye kureba macheki kuti ave nechokwadi chekuenderana
• MTCs kuenda ku EN 10204 3.1/3.2 yekupisa kuzere uye bvunzo kutsvaga

Chinhu chakakosha ndechekuti A106 Giredhi B inotsanangurwa kana sevhisi iri eseisina musonouyetembiricha-pamusoro. Kana chinodiwa chiri nzvimbo-tembiricha kana chimiro, vatengi vanowanzoenda kuASTM A53 pachinzvimbo; kana chinodiwa chiri mutsetse pombi ine PSL zvinodiwa, vanoenda kuAPI 5L. Kuchengeta peji rino rakajeka kuti "yepamusoro-temperature isina musono CS pipe" zvichabatsira Google kunzwisisa kuti URL iyi ndeyei.

• Seamless kabhoni simbi pombi inogadzirwa kune ASTM A106 / ASME SA106
• Grade B sechiyero; Giredhi A kana C kana zvichidikanwa neprojekiti
• Cheka-kusvika-kureba, magumo akakomberedzwa, kukoira / varnish uye kurongedza kunze kwenyika zviripo
• Yese bvunzo (hydro, NDE, mechaniki) yakanyorwa uye inoteedzera
• Yechitatu-kuongororwa kwebato (BV, SGS, LR, zvichingodaro) inogona kurongwa isati yatumirwa
• Ipa ruzivo rwekunatsa, simba uye makemikari zvidyarwa uko mapepa mapakeji anofanirwa kuenderana neEPC zvinodiwa
