1. Yintoni iJCOE LSAW Pipe?

Umbhobho we-JCOE LSAWyipayipi yentsimbi edityaniswe nge-arc ende engaphantsi komhlaba eyenziwe ngokwenza ipleyiti yentsimbi ethe tyaba ibe yimo ye-cylindrical ngokusebenzisa ulandelelwano lwe-JCO, ilandelwa kukwandiswa koomatshini okugcweleyo. Ngokungafaniyo nepayipi edityaniswe nge-spiral, ipayipi ye-LSAW inomthungo omnye othe tye weld weld, okwenza ukuba ifaneleke kwizicelo ezifuna ukuchaneka okuphezulu kunye nokuthembeka kwesakhiwo.

Kwizakhiwo ezikude nolwandle, iipayipi zamandla, kunye neeprojekthi zokwakha ezinzima, ubungakanani beepayipi eziqhelekileyo abusoloko bunganelanga. Iinjineli zinokufuna ububanzi bangaphandle obulungiselelwe wena, ubukhulu beendonga ezinzima, amanqanaba entsimbi ekhethekileyo, okanye iimfuno ezithile zokuhlola. Kule miyalelo esekelwe kwiprojekthi, imveliso enkulu ye-UOE inokuba lula ukuyitshintsha ngenxa yemodeli yayo yokuvelisa enomthamo omkhulu.

Ukwenziwa kwe-JCOE kubonelela ngokuguquguquka okukhulu kwiimilinganiselo ezenziwe ngokwezifiso kunye neebhetshi zemveliso ezincinci ngelixa kugcinwa iimfuno zomgangatho ezifunekayo kwizicelo ezibalulekileyo. I-Yuantai Derun isebenzisa itekhnoloji ye-JCOE kwiiprojekthi zemibhobho emikhulu kunye neendonga ezinzima, ixhasa usetyenziso kwiziseko zophuhliso, amandla, kunye nobunjineli bezakhiwo.

2. Ipayipi ye-JCOE vs UOE: Uthelekiso lweNkqubo

Ngaphambi kokuba ucacise, kuyanceda ukubona indlela iinkqubo ezine eziphambili ezihambelana ngayo nezinto ezimbini abathengi abazikhathaleleyo: ukuba yeyiphi i-geometry abanokuyenza, kunye nokuba iodolo yabo incinci kangakanani.

Ingcamango yenjineli:I-ERW ilungele imigca eqhelekileyo yodonga oluncinci, kwayeSI-SAW isetyenziswa kakhulu kwiindlela ezinkulu apho iimfuno ze-spiral welding kunye neprojekthi zamkelekile.I-JCOE LSAW yinkqubo eyenza i-OD eyenziwe ngokwezifiso, umbhobho onzima (masithi i-OD 720 mm × WIT 38 mm) kwiibhetshi ezincinci ezisekelwe kwiprojekthi.ngaphandle kokubangela isohlwayo sokutshintsha izixhobo zokusebenzisa imifanekiso emihlanu. (Jonga ulwazi lwethu olunzulu malungaI-LSAW vs. SSAW vs. Ingenamthungo.)

3. Zisetyenziswa phi iipayipi ze-JCOE LSAW?

Ngenxa yokuba i-JCOE iphatha ububanzi obungaqhelekanga kunye neendonga ezinzima ngobukhulu obuphathekayo, ibonakala naphi na apho intsimbi yolwakhiwo ifuna umthungo ochanekileyo noqinisekisiweyo we-longitudinal. Eyona ndlela ixhaphakileyo yokusebenzisa:

• Iimonopile zomoya zaselwandle kunye neziqwenga zotshintsho.Iimonopile zityhala ububanzi obuyi-8–12 m kwaye zifuna ubukhulu bodonga obuhambelanayo kunye nokujikeleza; i-JCOE ivumela igadi ukuba ifikelele kwi-geometry echanekileyo ngaphandle kokuzinikela kwe-UOE-scale.
• Izakhiwo zejakethi kunye namaqonga angaphandle kolwandle.Imilenze, ii-braces, kunye nezikhokelo zomqhubi zifuna umbhobho odonga olunzima onokunyamezelana kakhulu — kanye njengoko i-JCOE injalo.
• Imigca yokuhambisa ioyile negesi.Kwiindawo ezifuna i-WT eyenziwe ngokwezifiso okanye uhlobo oluthile olukufutshane ne-tie-in, i-JCOE inika isiqwenga esingenakukwazi ukusikwa yi-spiral mill.
• Iikholamu eziqinileyo zesakhiwo.Uphahla lwenkundla, iiholo zemiboniso, kunye neefreyimu zemizi-mveliso zisebenzisa iindawo ezinkulu ezixineneyo nezingqukuva apho ulawulo lobukhulu lubaluleke ngaphezu komthamo.

Kwimeko nganye umthengi akathengi itoni ebiza kancinci — bafuna umbhobho ohambelana nomzobo kwaye uphumelele ukuhlolwa okokuqala. Elo lithuba elizaliswa yiJCOE.

4. Yenziwa njani ipayipi ye-LSAW? Ukwenziwa kwe-JCOE Inyathelo ngeNyathelo

IgamaI-JCOEichaza ulandelelwano loomatshini olusetyenziselwa ukubumba ipleyiti yesinyithi esinzima:

Ipleyiti yentsimbi → Ukugoba kwe-J → Ukugoba kwe-C → Ukugoba kwe-O → Ukuwelda kwe-ID/OD SAW → Inyathelo E (Ukwandiswa)

I-Universal press dies igoba ipleyiti inyathelo ngenyathelo (J → C → O) — akukho zixhobo zikhethekileyo ezifunekayo kubungakanani ngabunye.

• Ukugoba kwangaphambili komphetho:Ukugoba ngoomatshini kudala imiphetho yepleyiti ukuya kwiradiyumu ekujoliswe kuyo, kususa amabala athe tyaba ebeya kuhlala kufutshane nomthungo.
• Ukugoba kuka-J:I-hydraulic press ejikelezileyo ijika ngokuthe chu umphetho omnye ube yiprofayili ethi "J".
• Ukugoba kwe-C:Umphetho ochaseneyo ucinezelwa inyathelo ngenyathelo kwi-"C" evulekileyo.
• Ukugoba kwe-O:I-press ivala ipleyiti ibe ngu-“O” ovulekileyo, ilungelelanisa imiphetho ukuze kufakwe i-submerged-arc welding.
• Ukuwelda kwe-Arc efakwe emanzini (i-SAW):Iipaseji zangaphakathi (ID) nezangaphandle (OD) ezininzi zidibanisa umthungo. Ukufakwa kobushushu obuphezulu kuqhuba ukudibana okunzulu kwaye kutshisa izinto ezingcolisayo ezinokubakho.

Inyathelo Lokwandisa (E): Ukwandiswa Kokubanda Koomatshini Obude Obupheleleyo

I-“E” yokugqibela kukwandiswa. Intloko yesandisi se-hydraulic enamacandelo amaninzi ihamba yonke ubude bangaphakathi bombhobho, iwandisa ukusuka ekuqaleni ukuya ekupheleni. Eli linyathelo elahlula i-JCOE kwiindawo ezilula zokugoba iipleyiti.

[ Umbhobho odibeneyo ongandiswanga ] → [ Intloko yokwandisa i-hydraulic yangaphakathi ] → [Ulungelelwano oluphuculweyo kunye nokujikeleza]

Ukwandiswa koomatshini obupheleleyo kunciphisa uxinzelelo olushiyekileyo kwaye kuvale ukujikeleza kunye nokuthe tye kuyo yonke ipayipi.

• Ukunciphisa uxinzelelo olushiyekileyo:Ukuwelda okwenziwayo kunye nokufakelwa iintambo ezininzi kushiya uxinzelelo loomatshini kunye nobushushu kwindawo ethile. Ukwandiswa okubandayo kwenza intsimbi idlule kancinci kwindawo yayo yokunwebeka, inciphise uxinzelelo olushiyekileyo kwaye iphucule uzinzo olunemilinganiselo kunye nokusebenza kwe-weld.
• Ukuqinisekisa ukulungiswa kwebala:Ukwandiswa kunyanzela umbhobho ukuba ube ngqukuva (ovality) kwaye ube tye. Iziphelo zombhobho ezicocekileyo zithetha ukulingana kwindawo endaweni yokuwelda ebaleni kunye nokulwa ngokulungelelaniswa.

5. Umzekelo woHluko lweeNdleko: I-oda ye-JCOE LSAW eyenziwe ngokwezifiso ye-75-Ton

Qaphela: La manani angezantsi abonisa izinto, asekelwe kwibhetshi emeleyo yeetoni ezingama-75 ezenziwe ngokwezifiso. Amaxabiso okwenyani axhomekeke kudidi lwentsimbi, iimfuno zesatifikethi, kunye ne-incoterms. Abelana ngazo ukubonisa ulwakhiwo lweendleko, kungekhona njengekowuteshini.

Abathengi basibuza rhoqo:"Kutheni ixabiso ngetoni nganye liphezulu kwi-odolo ye-JCOE encinci kunakwi-standard bulk run?"Impendulo enyanisekileyo icacileImodeli yexabiso "leMigangatho Emithathu":

Ixabiso lilonke lePipe eyenziwe ngokwezifiso = [Umgangatho wokuseta kunye nezixhobo] + [Umgangatho wezinto] + [I-NRE kunye nomgangatho wokuhlola]

Umzekelo osebenzayo: ukwabiwa kweendleko zeprojekthi

Imfuneko:Umbhobho we-API 5L PSL2 X65Q LSAW, OD 610 mm × WIT 32 mm (udonga olunzima olulungiselelwe wena).
Umthamo:Iitoni ezingama-75 zemetric (≈ 165 metres / 14 ubude be-11.8 m).

Ukuqonda isikali: Cinezela iodolo ukusuka kwi-75→Iitoni ezingama-300 kwaye iseti emiselweyo ye-$4,500 iyancipha ukusuka kwi-$60/ngetoni ukuya kwi-$15/ngetoni. Xa idibene nokuphucula okuncinci ekusebenzeni kakuhle ekusikeni iipleyiti kunye nokuwelda okuqhubekayo, ixabiso leyunithi liyancipha ukusuka kwi-$1,440/ngetoni ukuya malunga ne-$1,385/ngetoni.—ubungqina bokuba "iprimiyamu" kwiindlela ezenziwe ngokwezifiso iqhutywa yi-fixed overhead amortization, kungekhona inzuzo ephakanyisiweyo.

6. Ukuhlolwa kwePipe ye-LSAW: Iimfuno zoVavanyo lwe-UT vs RT

Amaqela okuthenga aphikisana ngokungapheliyo malunga nokuba ingaba ayaqhuba nazombiniUvavanyo lwe-Ultrasonic (UT) kunye novavanyo lwe-Radiographic (RT) kumthungo we-longitudinal kuyimfuneko okanye iindleko eziphindwe kabini. Uhlobo olufutshane: zibamba iindidi ezahlukeneyo zeziphene, ngoko ke ziyahambelana, azidingi mfuneko.

I-UT ezenzekelayo ihlola ubude bomthungo obuyi-100%; i-RT ekujoliswe kuyo iqinisekisa imiqondiso engacacanga kwiziphelo zepayipi.

Kutheni i-weld ingadlula i-UT kodwa ingaphumeleli kwi-RT (kwaye okuchaseneyo)

Umbuzo esiwufumana kakhulu:"Ngaba isiphene kumbhobho we-LSAW singadlula kwi-UT kodwa singaphumeleli kwi-RT?"

Ewe.I-Micro-cluster porosity okanye i-scattered slag ivumela amaza esandi ukuba adlule ngokukhanya okuncinci (adlula i-UT) kodwa avele ngokucacileyo njengee-voids kwifilimu ye-X-ray (ayiphumeleli i-RT). Yijike ijikeleze: i-sidewall crack eqinileyo ethe nkqo ehambelana nomqadi we-X-ray ayinakubangela sithunzi sibonakalayo (adlula i-RT) kodwa ibonakalisa umqadi we-ultrasonic ubuyela ngqo kwi-transducer (ayiphumeleli i-UT). UkucacisaI-API 5L PSL2Ngokwesiqhelo kufuneka zombini i-AUT full-length scanning kunye ne-spot RT verification, kuba umgangatho ubeka ulindelo oluqinileyo lwe-weld-integrity.EN 10219Iiprojekthi, ngokwahlukileyo, zilandela udidi lokuhlola kunye neemfuno zomthengi ezibhalwe kwi-odolo yokuthenga — ezisenokufuna okanye zingadingi indibaniselwano efanayo. (EyethuUkuthembeka kwe-weld ye-NDT eyi-100%isiqwenga sigubungela indlela yokuchaza ngokuchanekileyo nokuba yeyiphi na.)

7Ukwakha iiNesti zoMbhobho: Indlela yokunciphisa imithwalo yolwandle kwiimpahla ze-LSAW

Imithwalo yolwandle yepayipi enkulu iqhutywa yimithwaloivolumu, hayi ubunzima. Ngenxa yokuba i-JCOE yenza ubude kunye nobubanzi obukhethekileyo, ungayila ukuthunyelwa ukuze unciphise iindleko zokufika ngemitha nganye.

[ Ukwakha iindlwane zepayipi / i-telescoping ] → ipayipi encinci ye-OD ngaphakathi kwipayipi enkulu ye-OD = ivolumu eyongeziweyo
[ Ukulungiswa kwesikhongozeli ] → ubude obulungiselelwe wena (5.8 m / 11.8 m) = 100% isivuno somthamo wesikhongozeli

Ukubona ipayipi encinci ye-OD ngaphakathi kwenkulu kuguqula indawo ekhululekileyo ibe yimithwalo egciniweyo.

Umzekelo wokonga osebenzayo: iipayipi zokwakha ezisebenzisa iteleskopu

Umbhobho wangaphandle:I-OD 1016 mm × Ubunzima obuyi-25 mm LSAW (iitoni ezili-100)
Umbhobho wangaphakathi:OD 711 mm × Ubunzima 16 mm LSAW (70 Tons)

Ubude be-JCOE obuqhelekileyo bunganqunyulwa bube bukhulu ngokweembotyi (11.8 m kwiibhokisi ezingama-40HQ) kunye nee-spacers ezikhuselayo — ukwandisa isithuba ngelixa kuthintela imibhobho ukuba ingachukumisi xa idlula.

8Uluhlu lokujonga i-RFQ yepayipi ye-LSAW eyenziwe ngokwezifiso

Ukuze uphephe iingxaki zonxibelelwano eziqhelekileyo ngexesha lokulungiselela i-RFQ kwaye ufumane ikowuteshini echanekileyo kwi-oda ye-LSAW yesiko, hamba ngolu luhlu lokujonga:

• Iinkcukacha zobukhulu:Xela i-OD echanekileyo × i-WT echanekileyo ngeemilimitha (umz., 610 mm × 32 mm). Kuphephe ukubiza okungacacanga kwe-NPS/Shedyuli kwizinto ezixineneyo eludongeni.
• Umgangatho wezinto kunye nemeko yokuhanjiswa:Xela ibakala kunye nemeko (umz., i-API 5L PSL2 X65Q icinyiwe/iqiniswe, okanye i-EN 10219 S355J2H iqhelekile).
• Uvavanyo kunye nesatifikethi:Ugutyungelwe yi-NDT (i-100% AUT seam scan + i-RT yombhobho) kunye nenqanaba le-cert (i-MTC 3.1, okanye ingqina le-MTC 3.2 le-SGS / Lloyd's).
• Ukulungiselela nobude bokugqibela:I-engile ye-bevel (30° – 35° yokufakela intsimi) kunye nobude bethagethi (11.8 m ±10 mm yokukhupha isitya).

Izinto ezibalulekileyo ekufuneka ziqwalaselwe

• I-JCOE LSAW yenza i-OD eyenziwe ngokwezifiso, umbhobho onzima (ukuya kuthi ga kwi-50 mm WT) kwiibhetshi ezincinci ezisekelwe kwiprojekthi kunokuba i-UOE mill idla ngokufuna.
• Ukwandiswa kobushushu obupheleleyo (Inyathelo E) kunciphisa uxinzelelo olushiyekileyo kwaye kuqinisekisa ukulingana kwentsimi — ukulibaziseka kokuwelda kuncinci.
• Kwiinkqubo ezininzi ze-API 5L PSL2 ezibalulekileyo zemibhobho, uvavanyo lwe-ultrasonic oluzenzekelayo kunye novavanyo olongezelelweyo lwe-radiographic lunokucaciswa ngokuxhomekeke kwiinkcukacha ezifanelekileyo kunye neemfuno zomthengi; iiprojekthi ze-EN 10219 zilandela udidi lwazo lokuhlola oluchaziweyo.
• Ukwakha iindlwane zemibhobho kunokunciphisa umthwalo wolwandle malunga ne-45% ngokuhambisa umbhobho omncinci we-OD ngaphakathi kombhobho omkhulu we-OD.

9Imibuzo Ebuzwa Rhoqo (Imibuzo Ebuzwa Rhoqo)

Q1: Yintoni umahluko omkhulu phakathi kokwenziwa kwemibhobho ye-UOE kunye ne-JCOE LSAW?

Umahluko ukwindlela yokwenza izinto. I-UOE isebenzisa ii-dies eziqinileyo zesenzo esinye ukucinezela iipleyiti ezipheleleyo kwiimilo ze-U kunye ne-O, ngoko ke ifuna ukubaleka okukhulu ukuze ihlawule utshintsho lweedayi. I-JCOE isebenzisa ii-dies ezicinezelayo ze-universal ukugoba iipleyiti ngokuthe chu (J → C → O), ivumela ukuseta okuguquguqukayo okufanelekileyo kubungakanani obuqhelekileyo kunye neebhetshi ezincinci.

Umbuzo 2: Kutheni ixabiso ngetoni nganye liphezulu kwiiodolo ze-JCOE ezincinci ezenziwe ngokwezifiso?

Iibhetshi ezincinci zineendleko ezimiselweyo — ukulinganiswa koomatshini, ukwenziwa kweplate yovavanyo, uvavanyo lwe-hydrostatic, ukuseta i-NDT — zisasazwe kwiitoni ezimbalwa. Iifektri zentsimbi eluhlaza zongeza iiprimiyamu ezincinci ezingaphantsi kobushushu obuqhelekileyo. Ezo ziphezulu ezizinzileyo, hayi umda owongezelelweyo.

Umbuzo 3: Ukwandiswa koomatshini (iNyathelo E) kuthintela njani iingxaki zokuwelda ebaleni?

Ukwandiswa kobushushu obupheleleyo kunyanzela umbhobho ukuba ube nobubanzi obuchanekileyo, ujikeleze (ukujiya), kunye nokuthe tye kubude bawo bonke. Oko kuphelisa ukungalungelelani kwamalungu xa efakwa, okusindisa umsebenzi wokudibanisa kunye nokuthintela ukuqhekeka komthungo.

Umbuzo 4: Ngaba ndifuna zombini i-UT kunye ne-RT kumthungo?

Kwinkonzo ebalulekileyo ye-API 5L PSL2, ngokubanzi ewe — umgangatho uhlala ufuna zombini ukuskena okupheleleyo kwe-AUT kunye ne-spot RT. Umsebenzi we-EN 10219 ulandela udidi lokuhlola olubhalwe kwi-odolo yokuthenga. I-UT ibamba iziphene ezicwangcisiweyo (iintanda, ukungabikho kokudibana) kwaye inika ubunzulu; i-RT ibamba iziphene ze-volumetric (i-porosity, i-slag).

10Isiphelo
