Umbhobho weNtsimbi odityanisiweyo ngeLongitudinally Submerged Arc (LSAW).

Inkcazelo emfutshane:

Umbhobho we-LSAW ngumbhobho we-Longitudinal Submerged Arc Welding.

Itekhnoloji yemveliso yombhobho we-LSAW iyaguquguquka, kwaye inokuvelisa iinkcukacha kunye neemodeli ezingenakuveliswa ngumbhobho wentsimbi ojikelezayo, umbhobho wentsimbi ojikelezayo kunye nombhobho wentsimbi ongenamthungo.

Usetyenziswa njani i-LSAW eWelded Steel Pipe kwiMibhobho

Isiseko sesinyithi kunye nentsimbi ye-welding ziye zavavanywa ngokwenkcazo ye-API SPEC 5L, i-DIN, i-EN, i-ASTM, i-GOST standard kunye neminye imigangatho.

Kwakhona, umbhobho we-LSAW unokudityaniswa neeflange, ukuphakamisa amehlo kunye nezinye iindawo ngokuxhomekeke kwiimfuno zabathengi.

Umbhobho we-LSAW usetyenziselwa ukuhambisa ulwelo olufana ne-oyile, igesi kunye nothutho lwamanzi kunye nokusetyenziselwa iiprojekthi zonxweme kunye nokwakhiwa komhlaba.Ezi mveliso zenziwa eTshayina kwaye zithunyelwa kwamanye amazwe afana ne-United States of America, Canada, Indiya, Pakistan, Afrika, njl.

Inkqubo yokwenziwa kwemibhobho yentsimbi ye-LSAW

Inkqubo yokwenziwa kwe-LSAW yentsimbi yobukhulu obukhulu ichazwa kula manyathelo angezantsi:

1. I-Plate Probe: Le isetyenziselwa ukuvelisa i-diameter enkulu ye-LSAW joints kanye emva kokuba ingene kumgca wemveliso oluyinkqubo yokuqala yovavanyo lwe-ultrasonic.

2. Ukugaya: Umatshini osetyenziselwa ukungqusha wenza lo msebenzi ngepleyiti entlangothi-mbini yokusila ukuze ihlangabezane neemfuno zobubanzi bepleyiti kunye namacala ahambelana nokumila kunye nesidanga.

3. Icala eligobileyo ngaphambili: Eli cala liphunyezwa ngokusebenzisa umatshini wokugoba ngaphambili kumda weplate yokugoba.Umphetho wepleyiti kufuneka uhlangabezane neemfuno zegophe.

4. Ukubumba: Emva kwesinyathelo sokugoba kwangaphambili, kwisiqingatha sokuqala somatshini wokubumba we-JCO, emva kwentsimbi egxininisiweyo, icinezelwe ibe yimo "J" ngelixa kwelinye isiqingatha sentsimbi efanayo igobile kwaye icinezelwe. kwimilo ethi "C", emva koko ukuvuleka kokugqibela kwenza imilo ethi "O".

5. I-welding yangaphambili: Oku kukwenza intsimbi yombhobho edibeneyo ibe ngumthungo othe tye emva kokuba yenziwe kwaye emva koko isebenzise i-gas welding seam (MAG) ye-welding eqhubekayo.

6. Ngaphakathi weld: Oku kwenziwa nge tandem multi-wire submerged arc welding (malunga nocingo ezine) kwindawo engaphakathi umthungo wentsimbi umbhobho welding.

7. I-Weld yangaphandle: Ngaphandle kwe-weld yi-tandem ye-arc ye-tandem emininzi efakwe emanzini kwindawo engaphandle ye-LSAW yentsimbi yombhobho welding.

8. Uvavanyo lwe-Ultrasonic: Ngaphandle nangaphakathi komthungo ochanekileyo we-welded steel pipe kwaye macala omabini ezinto ezisisiseko adityaniswe ngokuhlolwa kwe-100%.

9. Ukuhlolwa kwe-X-reyi: Uhlolo lwe-X-reyi kwimizi-mveliso ye-TV lwenziwa ngaphakathi nangaphandle kusetyenziswa inkqubo yokulungisa imifanekiso ukuqinisekisa ukuba kukho ubuntununtunu bokubona.

10. Ukwandiswa: Oku kukuphumeza i-arc ye-arc efakwe emanzini kunye ne-straight seam yentsimbi yombhobho ubude bomngxuma ububanzi ukuze kuphuculwe ukuchaneka kobungakanani betyhubhu yentsimbi kunye nokuphucula ukuhanjiswa koxinzelelo kwityhubhu yentsimbi.

11. Uvavanyo lwe-Hydraulic: Oku kuqhutyelwa kumatshini wokuvavanya i-hydraulic yensimbi emva kokwandisa uvavanyo lwe-root-root ukuqinisekisa ukuba umbhobho wensimbi uhlangabezana neemfuno eziqhelekileyo kunye nomatshini onokurekhoda ngokuzenzekelayo kunye nokukwazi ukugcina.

12. I-Chamfering: Oku kubandakanya ukuhlolwa okwenziwa kumbhobho wensimbi ekupheleni kwayo yonke inkqubo.
