API 5L Tsarin Kera Bututun Karfe Welded
Nau'in 1. Karkace Welded: Karfe welded karfe bututuana yin su ne ta hanyar walda wani tsiri na karfe, wanda ke samar da kabu mai kama. Wannan tsari yana ba da damar samar da manyan bututun diamita kuma sau da yawa ya fi dacewa da farashi don wasu aikace-aikace.
Rufewa da Jiyya:Don haɓaka juriya da karko, waɗannan bututu na iya ɗaukar nau'ikan shafi daban-daban da hanyoyin jiyya, irin su fusion bonded epoxy (FBE) ko polyethylene mai Layer uku (3LPE).
Nau'in 2. Welding Resistance Electric (ERW):Gefuna na tsiri na karfe da aka kafa suna zafi ta amfani da juriya na lantarki. Ana amfani da matsi don ƙirƙira gefuna tare, ƙirƙirar walda mai ƙarfi ba tare da buƙatar kayan filler ba.
Nau'i na 3.Welding mai tsayi:
Welding Arc Submerged (SAW): Ana haɗa gefuna na bututun da aka kafa tare ta amfani da tsarin waldawar baka mai nitse, wanda ya haɗa da yin amfani da baka na lantarki da ƙwanƙolin ƙwanƙwasa don ƙirƙirar walda mai inganci mai ƙarfi.
Biyu Submerged Arc Welding (DSAW): Don bututu masu kauri, duka biyun ciki da na waje ana waldasu, suna tabbatar da cikakken shigar da ƙarfi.
