A53 Hluav Taws Xob- Resistance Welded Yeeb Nkab
A53 Tube Specifications
Gnee Steel Cov khoom lag luam muaj ntau yam ntawm A/SA53-B welded yeeb nkab hauv:
Qhov ntau thiab tsawg: 1/8 "NPS to 26" OD
Teem sijhawm: S / 10, S / 20, S / 40, STD, S / 60, S / 80, XH, S / 100, S / 120, S / 140, S / 160 thiab XXH
Scope
ASTM A53 thiab ASME SA53 yog npaj rau kev siv tshuab thiab kev siv siab thiab tseem siv tau rau kev siv zoo tib yam hauv chav dej, dej, roj thiab cua. Nws yog qhov tsim nyog rau kev siv vuam thiab kev tsim cov haujlwm uas muaj xws li coiling, dabtsi yog khoov, thiab flanging, raug rau qee yam kev tsim nyog.

Khoom siv thiab kev tsim khoom
Cov yeeb nkab welded yuav tsum tau ua los ntawm cov txheej txheem hauv qab no: qhib-hearth, hluav taws xob rauv, los yog cov pa oxygen. Weld seam ntawm hluav taws xob tiv thaiv welded yeeb nkab hauv Qib B yuav tsum tau kho cua sov tom qab vuam.
