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. Okwamanje zisesikhundleni esibalulekile emkhakheni wezokuthutha.amapayipiemhlabeni.
Niniukushisela amapayipi e-ERW, ukushisa kukhishwa lapho ugesi ugeleza ezindaweni zokuthintana zendawo yokushisela. Kushisa imiphetho emibili yensimbi kuze kube yilapho umphetho owodwa ungakha isibopho. Kulokhu, ngaphansi kwengcindezi yokuhlangana, imiphetho yepayipi elingenalutho 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 amazinga avame kakhulu ekufakeni amapayipi. Amapayipi ensimbi yekhabhoni e-ERW ASTM A53 ebanga A ne-B (kanye ne-galvanized) ASTM A252amapayipi ensimbi yekhabhoniAmapayipi enqwaba e-ASTM A500 ASTM A134 kanye ne-ASTM A135 amapayipi esakhiwo e-EN 10219 amapayipi e-S275, S355. Ipayipi Lensimbi Engagqwali le-ERW Amazinga Nemininingwane ye-ASTM A269 Ipayipi Lensimbi Engagqwali le-ASTM A270 Ipayipi Lensimbi Engagqwali le-ASTM A312 Ipayipi Lokufaka Amapayipi le-ASTM A790 Ipayipi Lensimbi Engagqwali le-Ferritic/Austenitic/Duplex. Ipayipi Lomugqa we-ERW API 5L B kuya ku-X70 PSL1 (PSL2 kumele ibe yinqubo ye-HFW) I-API 5CT J55/K55, N80 casing kanye ne-tubing.
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.
