Shiinaha Adeeg Heerkul Sarreya ASTM A106 A53 Gra/API 5L Grb/A179 A192 Derbiga Qafiifsan/Darbiga khafiifka ah
Dulmar
Waxaan isku dayeynaa heer sare, taageer macaamiisha", waxaan rajeyneynaa in ay noqoto kooxda ugu sareysa ee iskaashiga iyo ganacsiga ugu sarreeya ee shaqaalaha, alaab-qeybiyeyaasha iyo dukaamada, waxay ogaataa in la wadaago iyo suuq-geyn joogto ah oo loogu talagalay Carbon Steel Seamless tube / Pipe, Ka sokow, shirkadeena waxay ku dheggan tahay tayada sare iyo Qiimaha la awoodi karo, waxaana sidoo kale aan u soo bandhignaa shirkado OEM oo waaweyn magacyo badan oo caan ah oo wajahaya tartan adag oo suuq caalami ah, waxaan bilownay istaraatiijiyadda dhisidda sumadda oo aan cusbooneysiinay ruuxa "adeeg ku wajahan bini'aadamka iyo daacadnimada", ujeedaduna tahay in la helo aqoonsi caalami ah. iyo horumar waara.
ASTM A106 GR. Dhuumaha birta ee B waxay leedahay wax qabad alxanka oo wanaagsan. Sababtoo ah maadada C ee hooseeysa, guud ahaan ma jiro qaab adag oo adag oo ay ugu wacan tahay alxanka, iyo wadajirka alxanka ah ayaa leh caag wanaagsan iyo adag Habka alxanka oo dhan wuxuu heli karaa isku-dhafka alxanka oo lagu qanco iyada oo aan la helin tallaabooyin tignoolajiyadeed oo gaar ah.
ASTM A106 GR. B iyo 20# waxay isku mid yihiin isku dhafka kiimikada iyo qalabka farsamada oo inta badan la isku beddelo midba midka kale, laakiin kala duwanaansho ayaa jira, gaar ahaan marka la eego shuruudaha isticmaalka dheeraadka ah. Tusaale ahaan, qaadashada 20 # tusaale ahaan, GB50316 waxay qeexaysaa heerkulka ugu hooseeya ee hawlgalka of GB8163 20# tube steel waa -19℃, halka ASMR B31.3 ay qeexayso in heerkulka ugu yar ee lagu dabaqi karo A106 GR. B tube steel waa -29 ℃, waxaana jira xaalad aan wax saameyn ah lahayn. Inkastoo ay jiraan kala duwanaansho naqshadeynta naqshadeynta, sababta qoto dheer ayaa ah farqiga heerka xakamaynta ee maadada Mn. Soo saaraha ayaa laga yaabaa inuusan ka warqabin kordhintan , laakiin iibsaduhu waa inuu ka warqabaa kala duwanaanshahan oo uu u sheego soo saaraha shuruudaha wakhtiga iibka, haddii kale dhibaatooyin ayaa laga yaabaa inay ka soo baxaan shuruudo adag.
