OEM Spot Kulul / Qabow Rolled ASTM 42CrMo Q355b 20# 1045 1030 1052 Dhuumaha Birta ee aan Xunnayn
Sharaxaad Gaaban:
Tuubbooyinka birta ee saxda ah ee aan cillad lahayn ee loogu talagalay codsiyada qaabdhismeedka farsamada iyo iftiinka.
Waxaan ku tiirsanahay fikirka istiraatijiyadeed, casriyeynta joogtada ah ee dhammaan qaybaha, horumarka tignoolajiyada iyo dabcan shaqaalaheena sida tooska ah uga qaybqaata guushayada OEM Customized Factory Spot Hot / Cold Rolled ASTM 42CrMo Q355b 20# 1045 1030 1052 Dhuumaha Birta aan Xumaan ee Saxda / Wareegga /Hollow/Galvanized/Black/Tube Carbon/Alloy Steel Pipe, Koox khibrad leh ahaan waxaan sidoo kale aqbalnaa amarada ku habboon.Hadafka ugu weyn ee shirkadeena had iyo jeer waa in aan horumarino xusuus qancisa dhammaan dukaamaystayaashii, iyo in la dejiyo iskaashi ganacsi oo guul-guul ah oo mustaqbalka fog ah.

Tuubbooyinka birta ee saxda ah ee aan cillad lahayn ee loogu talagalay codsiyada qaabdhismeedka farsamada iyo iftiinka.Tani waxay keenaysaa sifooyin badan oo isku mid ah oo dhan tuubada marka loo eego tuubooyinka caadiga ah.Iyadoo tuubooyinka makaanikada loo soo saari karo qeexitaannada caadiga ah marka la codsado, guryaha "caadiga ah" waxay caadi ahaan soo saaraan xoogga wax-soo-saarka ee cabbirka saxda ah iyo dhumucda derbiga.Qaar ka mid ah codsiyada aadka loo sameeyay, xoogga wax-soo-saarka ayaa laga yaabaa inaan xitaa la cayimin oo tuubada farsamada ayaa la soo saaray "ku habboon isticmaalka".Tuubooyinka makaanikada waxaa ku jira codsiyo qaab dhismeed iyo mid aan dhisneyn oo ballaaran.
Haihui Steel, waxaanu ku dabaqnaa khibradeena birta iyo wax soo saarka si aanu u soo saarno alaabada tuubbooyinka farsamaysan ee wax qabadkoodu sarreeyo si loo daboolo baahiyahaaga.
Tan waxaa ka mid ah kaarboon, alloys iyo xitaa darajooyinka birta caadiga ah;la jeexjeexay, la caadiyeeyay oo la xanaaqay;culayska la yareeyey oo aan diiqada lahayn;demisay oo xanaaqsan.

Habaynta Gaarka ah
Alaabooyinka tubbada ee khaaska ah ee isku xidhka tuubooyinka waxay ku bilaabmaan birta tayada ugu sareysa.Darajada, falanqaynta kiimikada iyo xaaladda dusha si taxadar leh ayaa loo tixgaliyaa, iyo hababka wax soo saarka ayaa loo habeeyey si loo gaaro tubbada ugu fiican ee isticmaalka dhamaadka.
Habayntu waxay ka samaysan tahay tuubo wareegsan iyadoo sawir qabow laga sameeyay.Tuubada waxaa lagu sawiraa mander qaabaysan ama iyada oo loo sii marayo dhinta qaabaysan, ama labadaba.Dulqaadyada la wanaajiyay, dhammaynta iyo natiijadii sifooyinka farsamada.
