I-API 5L Spiral Welded Steel Pipes Uhlolojikelele:
Okujwayelekile: API 5L
Incazelo: I-API 5L icacisa izidingo zokwenziwa kwamazinga amabili okucaciswa kwemikhiqizo (PSL1 kanye ne-PSL2) yamapayipi ensimbi angenamthungo nashiselwe. Amapayipi e-SSAW (Spiral Submerged Arc Welded) awuhlobo lwamapayipi ensimbi ashiselwe akhiqizwa indlela ye-spiral welding, evumela ukukhiqizwa kwamapayipi amakhulu obubanzi.
1500MM SSAW Imininingwane Ebalulekile Yamapayipi Ensimbi Ashiselwe:
Ububanzi:1500mm (60 amayintshi)
Ukuqina Kwezindonga:Ubukhulu bodonga bungahluka kuye ngezidingo ezithile, kodwa amanani ajwayelekile asukela ku-6mm kuya ku-25mm noma ngaphezulu.
Ibanga Lensimbi:
PSL1: Amabanga ajwayelekile ahlanganisa A, B, X42, X46, X52, X56, X60, X65, X70.
Inqubo Yokukhiqiza:
I-SSAW (I-Spiral Submerged Arc Welding): Le nqubo ihilela ukusonteka okuqhubekayo kwe-hot-rolled steel strip ku-mandrel ejikelezayo nge-engeli ecacisiwe ku-eksisi yepayipi, okwenza umthungo ozungezayo. Umthungo ube usushiselwa ngaphakathi nangaphandle kusetshenziswa i-arc welding engaphansi.
Ubude:Ivamise ukuhlinzekwa ngobude obungu-12m (amafidi angama-40), kodwa ingasikwa kubude obuqondene nekhasimende.
I-Coating and Lining:
I-External Coating: Ingafaka i-3LPE, 3LPP, FBE, nezinye izinhlobo ukuze kuhlinzekwe ukuvikela ukugqwala.
I-Internal Lining: Ingafaka i-epoxy coating yokumelana nokugqwala, ulayini lukasimende lodaka lwamapayipi amanzi, noma ezinye izingilazi ezikhethekile.
Izinhlobo Zokugcina:
I-Plain Ends: Ifanele i-welding yasensimini noma ukuhlanganisa imishini.
I-Beveled Ends: Ilungiselelwe ukushiselwa.
Izicelo:
Ukudluliswa kukawoyela negesi: Kusetshenziswa kakhulu ekuthuthweni kukawoyela negesi yemvelo.
Ukudluliswa kwamanzi: Afanele amaphrojekthi amakhulu okuphakelwa kwamanzi.
Izinjongo Zesakhiwo: Ingasetshenziswa futhi ezinhlelweni zesakhiwo ezidinga amapayipi amakhulu obubanzi.
I-SSAW Welded Steel Pipes Ukuqinisekisa Ikhwalithi:
Amandla Okukhiqiza:Kuya ngebanga, amandla esivuno angasukela ku-245 MPa (eBangeni B) kuye ku-555 MPa (eBangeni X80).
Amandla Okuqina:Kuye ngebanga, amandla okuqina angasukela ku-415 MPa (weBanga B) ukuya ku-760 MPa (eBangeni X80).
Ukuhlolwa kwe-Hydrostatic:Ipayipi ngalinye lingaphansi kokuhlolwa kwe-hydrostatic ukuze kuqinisekiswe ubuqotho be-weld kanye nomzimba wepayipi.
Ukuhlolwa kobukhulu:Iqinisekisa ukuthi ipayipi ihlangabezana nobukhulu obucacisiwe nokubekezelela.
