Gaadhida Degdegga ah ee Kulul Duubka ah ASTM A106 GR.B Kaarboon Birta Tuubbada Xiran
Sharaxaad Gaaban:
ASTM A106/ASME SA106 waa qeexitaanka caadiga ah ee tuubooyinka birta kaarboonka ee aan fiicnayn ee codsiyada heerkulka sare.Waxay ka kooban tahay saddex darajooyin A, B iyo C, darajada sida caadiga ah loo isticmaalo waa A106 fasalka B. Looma isticmaalo oo keliya hababka dhuumaha sida saliidda iyo gaaska, biyaha, iyo gaadiidka slurry, laakiin sidoo kale in kuleyliyaha, dhismaha iyo codsiyada dhismaha.
U hoggaansanaanta aragtida "tayada, adeegyada, hufnaanta iyo kobaca", hadda waxaan ka helnay kalsooni iyo ammaan ka soo dukaameeyaha gudaha iyo dibedda ee Delivery Delivery for Hot Rolled ASTM A106 GR.B Kaarboon Steel Dhuuma-la'aan, Dhammaan badeecadaha waxaa lagu soo saaray qalab horumarsan. iyo hababka adag ee QC ee gadashada si ay u noqdaan qaar tayo sare leh.Ku soo dhawoow macaamiisha cusub iyo kuwa da'da cusub inay nala soo xiriiraan iskaashiga ganacsiga.
U hoggaansanaanta aragtida "tayada, adeegyada, hufnaanta iyo kobaca", hadda waxaan helnay kalsooni iyo ammaan ka soo dukaameysiga gudaha iyo dibeddaChina ASTM A106 GR.B birta birta ah ee aan xujayn, Intaa waxaa dheer, dhammaan xalalkayaga waxaa lagu soo saaray qalab horumarsan iyo hababka QC adag si loo hubiyo tayada sare.Haddii aad xiisaynayso mid ka mid ah alaabtayada, iska hubi inaadan ka labalabayn inaad nala soo xidhiidho.Waxaan ku dadaali doonaa inaan daboolno baahiyahaaga.
ASTM A106 tubbada darajada B waxay kiimiko ahaan u dhigantaa ASTM A53 Fasalka B iyo API 5L Fasalka B marka loo eego booska kiimikaad iyo sifooyinka farsamada, guud ahaan iyadoo la isticmaalayo birta kaarboon, oo leh ugu yaraan wax soo saarkiisu yahay 240 MPa iyo xoogga xajinta ee 415 MPa.
Tilmaamaha Heerka ASTM A106 ee Dhuumaha Birta aan Xumaan lahayn waxay leedahay saddex darajo, ASTM A106 Gr.A.B iyo C, mar kasta oo ay ka sarreeyaan darajada maadada, ayaa ka sii wanaagsan sifooyinka xoogga.
Hababka tijaabada ee ASTM A106 A, B, C waa imtixaan fidsan, tijaabo korantada aan burburin, tijaabada ultrasonic, test eddy current, test flux leakage test, hababka tijaabadan waa in la ogeysiiyaa ama lagala hadlaa macaamilka si loo go'aamiyo imtixaanka la samayn doono. loo isticmaalo.
