I-ASTM A53 Pipe Standard: Umhlahlandlela Wokusetshenziswa Okujwayelekile Amapayipi ensimbi we-ASTM A53 angelinye lamazinga asetshenziswa kakhulu amapayipi ensimbi emhlabeni emkhakheni wamapayipi nokwakha. Kunezinhlobo ezintathu: i-LSAW, i-SSAW, ne-ERW, kodwa izinqubo zabo zokukhiqiza zihlukile futhi ukusetshenziswa nakho kuhlukile.
1. I-Astm A53 LSAW Ipayipi Lensimbi(I-Longitudinal Submerged arc Welding)
Ipayipi le-LSAW lakhiwe ngokugobisa ipuleti lensimbi ngobude bese liyashiselwa futhi umthungo oshiselwe ungaphakathi nangaphandle kwepayipi! Amapayipi e-LSAW, anezinsimbi ezisezingeni eliphezulu, alungele ukusetshenziswa kwe-high-pressure kawoyela negesi. Ama-weld anamandla aphezulu kanye nezindonga eziwugqinsi zenza la mapayipi afanelekele umfutho ophakeme wamapayipi kawoyela negesi, ukusetshenziswa kolwandle.
2. I-Astm A53I-SSAWIpayipi Lensimbi(Spiral Submerged Arc Welded)
I-Spiral Submerged Arc Welded (SSAW) Pipe yenziwa kusetshenziswa indlela yokushisela ye-arc e-spiral submerged. Ama-spiral welds azo enza kube lula ukukhiqiza futhi awenze alungele amapayipi amanzi anengcindezi ephakathi nendawo noma ephansi noma ekusetshenzisweni kwesakhiwo.
3.I-Astm A53ERWIpayipi Lensimbi(Electric Resistance Welded)
Amapayipi e-ERW enziwa ngokushisela ukumelana nogesi, ukuze i-radius encane yokugoba idingekile ukuze igobe ekulungiseleleni i-weld evumela amapayipi okukhiqiza ane-diameter encane nama-welds anembile, izindleko zokukhiqiza zamapayipi anjalo ziphansi kakhulu. Asetshenziswa kakhulu ekwakheni amafreyimu, amashubhu emishini, kanye nokuhanjiswa koketshezi ngengcindezi ephansi.
Okulandelayo umehluko omkhulu:
Inqubo yokushisela: Izinqubo ze-LSAW/SSAW zibandakanya i-arc welding engaphansi kwamanzi, i-ERW iyinqubo yokushisela ukumelana nogesi.
Ububanzi & Ukuqina Kodonga: Amapayipi e-LSAW anomadayamitha amakhulu anezindonga eziwugqinsi uma kuqhathaniswa namapayipi e-SSAW kanye ne-ERW.
Ukuphatha Ingcindezi: LSAW > ERW/SSAW.
