Umgangatho wePipe ye-ASTM A53: ISikhokelo sokuSetyenziswa Jikelele kwe-ASTM A53 imibhobho yensimbi yenye yezona migangatho zisetyenziswa kakhulu kwimibhobho yensimbi kwihlabathi kwintsimi yeepayipi kunye nokwakhiwa. Kukho iintlobo ezintathu: i-LSAW, i-SSAW, kunye ne-ERW, kodwa iinkqubo zabo zokuvelisa zahlukile kwaye ukusetyenziswa kwahlukile.
1. I-Astm A53 LSAUmbhobho wentsimbi W(I-Longitudinal Submerged arc Welding)
I-LSAW Umbhobho wenziwa ngokugoba ipleyiti yentsimbi ngobude emva koko idityaniswe kwaye umthungo odityanisiweyo ungaphakathi nangaphandle kombhobho! Imibhobho ye-LSAW, enezinsimbi ezikumgangatho ophezulu, ilungele ukusetyenziswa kwe-oyile ephezulu kunye negesi. Iiwelds ezinamandla aphezulu kunye neendonga ezingqingqwa zenza le mibhobho ifaneleke kuxinzelelo oluphezulu lweoyile kunye nemibhobho yegesi, ukusetyenziswa kolwandle.
2. I-Astm A53SSAWUmbhobho wentsimbi(Spiral Submerged Arc Welded)
I-Spiral Submerged Arc Welded (SSAW) Umbhobho wenziwa ngokusebenzisa i-spiral submerged arc welding method. I-spiral welds yazo yenza ukuba imveliso ibe yeyongayo kwaye iyenze ilungele imibhobho yamanzi yoxinzelelo oluphakathi ukuya kuxinzelelo oluphantsi okanye kusetyenziso lwezakhiwo.
3.I-Astm A53ERWUmbhobho wentsimbi(Ukuxhathisa koMbane kuWelded)
Imibhobho ye-ERW yenziwe nge-welding ye-electric resistance welding, ukwenzela ukuba i-radius encinci ye-curvature iyadingeka ukugoba ekulungiseleleni i-weld evumela imibhobho yokuvelisa nge-diameter encinci kunye ne-welds echanekileyo, iindleko zemveliso zemibhobho enjalo ziphantsi. Zisetyenziswa kakhulu kulwakhiwo lwezakhelo zokwakha, iityhubhu yoomatshini, kunye nokuhanjiswa kolwelo kuxinzelelo oluphantsi.
Oku kulandelayo ngowona mahluko uphambili:
Inkqubo yeWelding: Iinkqubo ze-LSAW / SSAW zibandakanya i-arc welding ephantsi kwamanzi, i-ERW yinkqubo yokumelana nombane.
Idayamitha kunye nokutyeba kodonga: Imibhobho ye-LSAW inobubanzi obukhulu kunye neendonga ezityebileyo xa kuthelekiswa ne-SSAW kunye ne-ERW imibhobho.
Ukuphathwa koxinzelelo: LSAW > ERW/SSAW.
