API 5L ASTM A53/A106 Gr.B Rolling Cold/Kulul Birta Kaarboon Bir ah oo aan Xirnayn Tuubo Madow oo khafiif 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.
"Tayada bilawga ah, Daacadnimada saldhig ahaan, Caawin daacad ah iyo faa'iido wadaag" waa fikraddayada, si aan si joogto ah u soo saarno oo aan u daba galno heerka ugu sarreeya API 5L ASTM A53/A106 Gr.B Rolling Cold/Hit Hot Rolling Carbon Steel Dhuumaha Fudud ee Madaw, Sababtoo ah waxaan joognaa khadkan ilaa 10 sano.Waxaan helnay taageerada alaab-qeybiyeyaasha ugu fiican ee tayada iyo qiimaha.Waxaanan ka saarnay alaab-qeybiyeyaal tayadoodu liidato.Hadda warshado badan oo OEM ah ayaa nala kaashaday sidoo kale.
"Tayada bilawga ah, Daacadnimada sida saldhigga, Caawin daacad ah iyo faa'iido wadaag" waa fikraddayada, si aan si joogto ah u soo saarno oo aan u raadinno heerka ugu sarreeyaShiinaha Dhuumaha Birta aan Xumaan lahayn iyo St37 St52 1020 1045 A106b Dhuumaha dareeraha ahWaxaan aaminsanahay in xiriirka ganacsi ee wanaagsan uu u horseedi doono faa'iido wadaag iyo horumar labada dhinacba ah.Waxaan hadda la sameysannay xiriir iskaashi oo fog oo guul leh oo lala yeesho macaamiil badan iyada oo loo marayo kalsoonida ay ku qabaan adeegyadayada gaarka ah iyo daacadnimada ganacsiga.Waxaan sidoo kale ku raaxaysannaa sumcad sare iyada oo loo marayo waxqabadkayaga wanaagsan.Waxqabad ka wanaagsan waxa la filayaa in uu noqdo mabda'ayada daacadnimada.Cibaadada iyo xasiloonida waxay ahaan doonaan sidii hore.
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.
