ERW amapayipi ensimbizenziwa nge frequency low noma high frequency kagesi ukumelana "resistance".Amapayipi ayindilinga ashiselwe kusuka kumashidi ensimbi ane-longitudinal seams.Isetshenziselwa ukuthutha igesi nezinto eziwuketshezi ezifana nowoyela negesi yemvelo, futhi ingahlangabezana nezidingo ezihlukahlukene zokucindezela okuphezulu nokuphansi.Njengamanje inesikhundla esibalulekile endimeni yezokuthuthaamapayipiemhlabeni.
Niniukushisela amapayipi e-ERW, ukushisa kukhishwa lapho okwamanje kugeleza ezindaweni zokuthintana zendawo yokushisela.Ishisisa imiphetho emibili yensimbi kuze kube yilapho unqenqema olulodwa lungakha isibopho.Kulesi simo, ngaphansi kwengcindezi ehlangene, imiphetho yepayipi engenalutho iyancibilika futhi ikhishwe ndawonye.NgokuvamileAmapayipi e-ERWabe nobukhulu bangaphandle ububanzi obungama-intshi angu-24 (609 mm), amapayipi amakhulu enziwa kusetshenziswa i-SAW.
Maningi amapayipi angenziwa kusetshenziswa indlela ye-ERW.Ngezansi sibala izindinganiso ezivame kakhulu ekufakeni amapayipi.ERW ASTM A53 Ibanga A no-B amapayipi ensimbi ekhabhoni (kanye namagalani) ASTM A252carbon steel amapayipiI-ASTM A500 inqwaba yamapayipi ASTM A134 kanye ne-ASTM A135 amapayipi esakhiwo EN 10219 amapayipi S275,S355 amapayipi.ERW Ipayipi Lensimbi Engagqwali ASTM A269 Amazinga & Ukucaciswa ASTM A270 Ipayipi Lensimbi Engagqwali ASTM A312 Ipayipi le-ATM A312 Ipayipi Lensimbi I-A312 I-AsTM I-Stainless Dut Ipayipi Lensimbi Engagqwali .API ERW line pipe API 5L B to X70 PSL1 (PSL2 kumele kube HFW inqubo) API 5CT J55/K55,N80 casing kanye neshubhu.
Ukusetshenziswa kanye nokusetshenziswa kwepayipi lensimbi le-ERW: Ipayipi lensimbi i-ERW lisetshenziselwa ukuthutha igesi nezinto eziwuketshezi ezifana nowoyela negesi yemvelo, futhi lingahlangabezana nezidingo zomfutho ophansi nophezulu.Eminyakeni yamuva nje, ngokuthuthukiswa kobuchwepheshe be-ERW, amapayipi ensimbi amaningi e-ERW asetshenziswa ezindaweni zikawoyela negesi, embonini yezimoto, njll.
