Umgangatho wePipe ye-ASTM A53: Isikhokelo sokuSebenzisa ngokubanzi Iipayipi zentsimbi ze-ASTM A53 ngomnye wemigangatho esetyenziswa kakhulu kwiipayipi zentsimbi kwihlabathi liphela kwicandelo leepayipi nolwakhiwo. Kukho iintlobo ezintathu: i-LSAW, i-SSAW, kunye ne-ERW, kodwa iinkqubo zazo zokuvelisa zahlukile kwaye ukusetyenziswa kwazo kwahlukile.
1. I-Astm A53 LSAUmbhobho weNtsimbi ye-W(Ukuwelda kwe-arc engaphantsi komhlaba eLongitudinal)
Umbhobho we-LSAW wenziwa ngokugoba ipleyiti yentsimbi ngobude uze udityaniswe kwaye umthungo odityanisiweyo ungaphakathi nangaphandle kombhobho! Imibhobho ye-LSAW, enentsimbi ezikumgangatho ophezulu, ifanelekile kwizicelo zeoyile kunye negesi ezinoxinzelelo oluphezulu. Ii-welds ezinamandla aphezulu kunye neendonga ezixineneyo zenza le mibhobho ifaneleke kwimibhobho yeoyile kunye negesi enoxinzelelo oluphezulu, ukusetyenziswa kolwandle.
2. I-Astm A53I-SSAWUmbhobho wentsimbi(I-Spiral Submerged Arc Welded)
Umbhobho we-Spiral Submerged Arc Welded (SSAW) wenziwa ngokusebenzisa indlela ye-spiral submerged arc welding. Ii-spiral welds zazo zenza kube lula ukuvelisa kwaye zizenze zilungele ukusetyenziswa kwamanzi aphakathi ukuya kwaphantsi okanye ukusetyenziswa kwesakhiwo.
3.I-Astm A53I-ERWUmbhobho wentsimbi(I-Welded yokumelana nombane)
Iipayipi ze-ERW zenziwe nge-electric resistance welding, ukuze kufuneke i-radius encinci yokugoba ekulungiseleleni i-weld evumela ukwenziwa kweepayipi ezinobubanzi obuncinci ezine-welds ezichanekileyo, iindleko zokuvelisa ezo payipi ziphantsi kakhulu. Zisetyenziswa kakhulu ekwakheni izakhelo zokwakha, iityhubhu zoomatshini, kunye nokuhanjiswa kolwelo ngoxinzelelo oluphantsi.
Nazi izinto eziphambili ezahlukileyo:
Inkqubo yokuWeldaIinkqubo ze-LSAW/SSAW zibandakanya ukuwelda kwe-arc engaphantsi komhlaba, i-ERW yinkqubo yokuwelda yokumelana nombane.
Ububanzi kunye nobukhulu bodongaIipayipi ze-LSAW zinobubanzi obukhulu obuneendonga ezityebileyo xa kuthelekiswa neepayipi ze-SSAW kunye ne-ERW.
Ukuphatha Uxinzelelo: LSAW > ERW/SSAW.
