Inkqubo yokwenziwa kweElbow engenamthungo (Ukugoba ubushushu kunye nokugoba okubandayo)

Enye yeendlela eziqhelekileyo zokuvelisa ingqiniba kukusebenzisa ukugoba kwe-mandrel eshushu kwimibhobho yentsimbi ethe tye.Emva kokufudumeza umbhobho wensimbi kwiqondo lokushisa eliphakamileyo, umbhobho utyhalwa, wandiswa, ugobe ngezixhobo zangaphakathi ze-mandrel isinyathelo ngesinyathelo.Ukusebenzisa ukugoba kwe-mandrel eshushu kunokuvelisa uluhlu olubanzi lobungakanani bengqiniba engenamthungo.Iimpawu zokugoba mandrel zixhomekeke ngamandla kwimilo edibeneyo kunye nemilinganiselo ye-mandrel.Ukusetyenziswa kweenzuzo zokugoba iingqiniba ezishushu ziquka ukutenxa kobukhulu obuncinci kunye neradiyasi eyomeleleyo yokugoba kunolunye uhlobo lwendlela yokugoba.Ngeli xesha, ukusebenzisa ukugoba endaweni yokugoba okwenziwe kwangaphambili kunciphisa kakhulu inani leentsimbi ezifunekayo.Oku kunciphisa inani lomsebenzi ofunekayo kwaye kwandisa umgangatho kunye nokusetyenziswa kwemibhobho.Nangona kunjalo, ukugoba okubandayo yinkqubo yokugoba umbhobho wentsimbi othe tye kumaqondo obushushu aqhelekileyo kumatshini wokugoba.Ukugoba okubandayo kufanelekileyo kwimibhobho enobubanzi obungaphandle be-17.0 ukuya kwi-219.1 mm, kunye nobukhulu bodonga 2.0 ukuya kwi-28.0 mm.Irediyasi yokugoba ecetyiswayo yi-2.5 x Yenza.Ngokuqhelekileyo kwiradiyasi yokugoba ye-40D.Ngokusebenzisa ukugoba okubandayo, sinokufumana iingqiniba zerediyasi ezincinci, kodwa kufuneka sipakishe izinto zangaphakathi ngesanti ukunqanda ukushwabana.Ukugoba okubandayo yindlela yokugoba ekhawulezayo nengabizi kakhulu.Lukhetho olukhuphisanayo lokwenza imibhobho kunye neengxenye zomatshini.

Inkqubo yokwenziwa kweElbow eWelded (Encinci & Enkulu)

Iingqiniba ezidityanisiweyo zenziwe kwiipleyiti zentsimbi, ngoko ayizizo iingqiniba zentsimbi ezingenamthungo.Sebenzisa i-mold kwaye ucinezele ipleyiti yentsimbi kwimilo yengqiniba, emva koko weld i-seam ibe yintsimbi yokugqiba.Yindlela endala yokuvelisa iingqiniba.Kutshanje iingqiniba zobukhulu ezincinci ziphantse ziveliswa kwimibhobho yentsimbi ngoku.Ubukhulu bengqiniba, umzekelo, kunzima kakhulu ukuvelisa iingqiniba ngaphezu kwe-36” OD ukusuka kwimibhobho yentsimbi.Ke ngokuqhelekileyo yenziwe kwiipleyiti zentsimbi, ukucinezela ipleyiti kwimilo yesiqingatha sengqiniba, kunye nokuwelda iihafu ezimbini kunye.Ekubeni i-elbows ifakwe emzimbeni wayo, ukuhlolwa kwe-welding joint kuyimfuneko.Ngokuqhelekileyo sisebenzisa ukuhlolwa kwe-X-Ray njenge-NDT.

Olu luhlu lubandakanya iiklasi ezimbini eziqhelekileyo, i-WP & CR, ye-austenitic stainless stainless fittings edibeneyo yokwakha engenamthungo kunye ne-welded.
Izixhobo zodidi lweWP zenziwe ngokweemfuno ze-ASME B16.9 kunye ne-ASME B16.28 kwaye zohlulwe zaba ziindidi ezingaphantsi ezintathu ngolu hlobo lulandelayo:

I-WP -Yenziwe kwimveliso engenamthungo ngendlela engenamthungo yokuvelisa.
I-WP - W Ezi zixhobo ziqulethe i-welds kunye nazo zonke ii-welds ezenziwe ngumenzi ofanelekileyo kubandakanywa ukuqala kwe-pipe weld ukuba umbhobho wawuxutywe kunye nokongezwa kwezinto zokuzalisa i-radiographed.Nangona kunjalo akukho radiography eyenziwayo kwi-weld yepayipi yokuqalisa ukuba umbhobho wawudityaniswe ngaphandle kokongezwa kwezinto zokuzalisa.
I-WP-WX Ezi zifakelo ziqulethe i-welds kunye nazo zonke ii-welds nokuba zenziwe ngumvelisi ofanelekileyo okanye ngumenzi wezinto eziqalayo zenziwe nge-radiographed.

Izixhobo zokufakwa kwiiKlasi zeCR zenziwa ngokweemfuno ze-MSS-SP-43 kwaye azifuni iimviwo ezingonakalisi.

Ngaphantsi kwe-ASTM A403 amabakala amaninzi ayafumaneka ngokuxhomekeke kukwakheka kweekhemikhali.Ukhetho luya kuxhomekeka kwimathiriyeli yombhobho eqhagamshelwe kwezi zifakelo.Amanye amabakala akhoyo phantsi kolu nkcukacha kunye neenkcukacha zemathiriyeli yombhobho edityanisiweyo adweliswe ngezantsi:

I-ASTM A420

Le ngcaciso igubungela intsimbi yekhabhoni ekhandiweyo kunye nokufakwa kwentsimbi yealloyi yolwakhiwo olungenamthungo & oludityanisiweyo olulungiselelwe ukusetyenziswa kumaqondo obushushu aphantsi.Ibandakanya amabanga amane i-WPL6, WPL9, WPL3 & WPL8 ngokuxhomekeke kukwakheka kweekhemikhali.Ufakelo lwe-WPL6 lunempembelelo evavanyiweyo kwiqondo lobushushu - 50° C, i-WPL9 ku- -75° C, i-WPL3 ku- -100° C kunye ne-WPL8 ku- -195° C ubushushu.

Imilinganiselo yoxinzelelo evumelekileyo yofakelo ingabalwa njengombhobho othe tye ongenamthungo ngokuhambelana nemigaqo esekwe kwicandelo elisebenzayo le-ASME B31.3.

Ubunzima bodonga lombhobho kunye nohlobo lwempahla buya kuba yinto eyalelwe ukuba i-fittings isetyenziswe, isazisi sazo kwiifittings endaweni yokumakisha ukulinganiswa koxinzelelo.
