Ulwazi Oluhlobene Ne-ERW

        Amapayipi ensimbi e-ERWZenziwe ngokumelana nogesi okuphansi noma okunemvamisa ephezulu. Zingamapayipi ayindilinga ahlanganiswe ngamashidi ensimbi anezithungo ezinde. Zisetshenziselwa ukuthutha igesi nezinto eziwuketshezi ezifana namafutha negesi yemvelo, futhi zingahlangabezana nezidingo ezahlukahlukene zokucindezela okuphezulu nokuphansi. Njengamanje ithatha indawo ebalulekile emkhakheni wamapayipi okuthutha emhlabeni.
Lapho kushiselwa amapayipi e-ERW, ukushisa kukhishwa lapho umsinga ugeleza ezindaweni zokuthintana zendawo yokushisela. Kushisa imiphetho emibili yensimbi kuze kube yilapho umphetho owodwa ungakha isibopho. Kulesi simo, ngaphansi kwengcindezi yokuhlangana, imiphetho yepayipi engenalutho iyancibilika futhi ikhishwe ndawonye.

NgokuvamileAmapayipi e-ERWanobubanzi obuphezulu bangaphandle obungamasentimitha angu-609 (24 mm), amapayipi amakhulu enziwa kusetshenziswa i-SAW.
Kunezipayipi eziningi ezingenziwa kusetshenziswa indlela ye-ERW. Ngezansi sibala izindinganiso ezivame kakhulu ekufakweni kwamapayipi.
Amapayipi ensimbi yekhabhoni e-ERW ASTM A53 Grade A kanye ne-B (kanye ne-galvanized) Amapayipi ensimbi yekhabhoni e-ASTM A252 Amapayipi enqwaba e-ASTM A500 Amapayipi esakhiwo e-ASTM A134 kanye ne-ASTM A135Amapayipi e-EN 10219 S275, amapayipi e-S355.
Ipayipi Lensimbi Engagqwali le-ERW ASTM A269 Amazinga kanye Nemininingwane Ipayipi Lensimbi Engagqwali le-ASTM A270 ASTM A312 Ipayipi Lokufaka Amapayipi Ipayipi Lensimbi Engagqwali le-ASTM A790 Ipayipi Lensimbi Engagqwali le-Ferritic/Austenitic/Duplex.
Ipayipi lomugqa we-API ERW API 5L B kuya ku-X70 PSL1 (PSL2 kumele ibe yinqubo ye-HFW) API 5CT J55/K55, N80ikheyisi kanye nepayipi.
Ukusetshenziswa kanye nokusetshenziswa kwepayipi lensimbi le-ERW: Ipayipi lensimbi le-ERW lisetshenziselwa ukuthutha igesi nezinto eziwuketshezi ezifana namafutha negesi yemvelo, futhi lingahlangabezana nezidingo zomfutho ophansi nophezulu. Eminyakeni yamuva nje, ngokuthuthukiswa kobuchwepheshe be-ERW, amapayipi ensimbi e-ERW amaningi asetshenziswa emikhakheni kawoyela negesi, embonini yezimoto, njll.
