API 5L Spiral Welded Steel Pipes Overview:
Umgangatho: API 5L
Inkcazo: I-API 5L ichaza iimfuno zokwenziwa kwamanqanaba amabini enkcazo yemveliso (PSL1 kunye ne-PSL2) yeepayipi zentsimbi ezingenamthungo kunye ne-welded. I-SSAW (i-Spiral Submerged Arc Welded) imibhobho luhlobo lombhobho wentsimbi odityanisiweyo oveliswe ngendlela ye-spiral welding, evumela ukuveliswa kwemibhobho emikhulu yobubanzi.
1500MM SSAW Imibhobho yentsimbi eDidiweyo IiNgcaciso eziphambili:
Ububanzi:1500mm (60 intshi)
Ukutyeba kweendonga:Ubunzima bodonga bunokwahluka ngokuxhomekeke kwiimfuno ezithile, kodwa amaxabiso aqhelekileyo avela kwi-6mm ukuya kwi-25mm okanye ngaphezulu.
Ibakala lentsimbi:
PSL1: Amanqaku aqhelekileyo aquka A, B, X42, X46, X52, X56, X60, X65, X70.
Inkqubo yokuVelisa:
I-SSAW (i-Spiral Submerged Arc Welding): Le nkqubo ibandakanya ukuguquka kwentsimbi eshushu-eqengqelekayo kwi-mandrel ejikelezayo kwi-engile echaziweyo kwi-axis yombhobho, eyenza i-spiral seam. Umthungo ke udityaniswe ngaphakathi nangaphandle usebenzisa i-arc welding ephantsi kwamanzi.
Ubude:Ngokuqhelekileyo ibonelelwa ngobude be-12m (40 iinyawo), kodwa inokusikwa kubude obukhethekileyo bomthengi.
Ukwaleka kunye noLwango:
I-Coating yangaphandle: Ingabandakanya i-3LPE, i-3LPP, i-FBE, kunye nezinye iintlobo zokubonelela ngokhuseleko lokubola.
ULuhlu lwangaphakathi: Lunokubandakanya ukugquma kwe-epoxy ukuze kuxhathise ukudleka, udaka lwesamente eludaka lwemibhobho yamanzi, okanye ezinye iilayile ezikhethekileyo.
Iintlobo Zokuphela:
I-Plain Ends: Ifanelekile kwi-welding yasendle okanye i-mechanical coupling.
Iziphelo eziBeveled: Zilungiselelwe ukuwelda.
Usetyenziso:
Ukuhanjiswa kwe-oyile kunye negesi: Isetyenziselwa kakhulu ukuthutha ioli kunye negesi yendalo.
UThutho lwaManzi: Afanelekile kwiiprojekthi ezinkulu zokubonelela ngamanzi.
Iinjongo zoLwakhiwo: Isenokusetyenziswa kwizicelo zesakhiwo ezifuna imibhobho emikhulu edayamitha.
UQinisekiso loMgangatho weMibhobho yentsimbi yeSSAW:
Unikeze Amandla:Ngokuxhomekeke kwibakala, amandla esivuno anokuqala ukusuka kuma-245 MPa (kwiBanga B) ukuya kuma-555 eMPa (kwiBakala X80).
Tensile strength:Kuxhomekeka kwibakala, amandla e-tensile anokuqala ukusuka ku-415 MPa (kwiBanga B) ukuya kuma-760 MPa (kwiBakala X80).
Uvavanyo lweHydrostatic:Umbhobho ngamnye uphantsi kovavanyo lwe-hydrostatic ukuqinisekisa ukunyaniseka kwe-weld kunye nomzimba wombhobho.
Ukuhlolwa komda:Uqinisekisa ukuba umbhobho udibana nemilinganiselo ethile kunye nokunyamezela.
