Warshada Shiinaha ee Dhuumaha birta ah ee Dhuumaha Jumlada ah ee aan Xumaan lahayn X42 X46 X52 X56 X60 X65 X70 Tuubbada Birta Birta ah ee aan Xirnayn ee leh Dhuumaha Saliidda Gaaska Dabiiciga ah
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.
Waa hab fiican oo lagu sii wanaajin karo alaabtayada iyo dayactirka.Hadafkayagu wuxuu noqon lahaa in aan horumarino alaabada kheyraadka leh macaamiisha la kulanka sare ee China Factory for Steel Pipeline Xirmooyinka Dhuumaha Tubta X42 X46 X52 X56 X60 X65 X70 Tuubbada Birta Birta ah ee Bilaashka ah oo leh Dhuumaha Saliida Gaaska Dabiiciga ah, Shirkadeena waxay ku adkaysanaysaa hal-abuurnimo si kor loogu qaado waara horumarinta ururka, oo naga dhigaysa alaab-qeybiyeyaasha tayada sare leh ee gudaha.
Waa hab fiican oo lagu sii wanaajin karo alaabtayada iyo dayactirka.Hadafkayagu waxa uu noqon lahaa in aan u horumarino agabka waxtarka leh macaamiisha leh kulan heer sare ahChina Steel Tube iyo Birta, Badeecadaha iyo adeegyadayada wanaagsan awgeed, waxaan sumcad wanaagsan iyo kalsooni ka helnay macaamiisha gudaha iyo kuwa caalamiga ah.Haddii aad u baahan tahay macluumaad dheeraad ah oo aad xiisaynayso mid ka mid ah alaabtayada, fadlan xor u noqo inaad nala soo xidhiidho.Waxaan rajeyneynaa inaan noqono alaab-qeybiyahaaga mustaqbalka dhow.
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.
