Dulmar
We try for excellence, service the customers", hopes to be the most effective Cooperation workforce and dominator company for staff, suppliers and shoppers, realize price share and current marketing for High Pressure Seamless Steel Pipe for Liquid Transportation, We wholeheartedly welcome shoppers all Adduunka oo dhan u kaalay si aan u tagno xaruntayada wax soo saarka oo ay nala yeeshaan wada shaqayn guuleed kale si ay u siiyaan macaamiisheena kala duwan oo wax ku ool ah oo badeecooyin iyo xal.
Tuubooyinka dareeraha ah, marka lagu daro heerka Ameerika, heerar badan oo Japan ah ayaa loo isticmaalaa adduunka. Waxaa ka mid ah, JIS G3454 STPG370 waa shay caadi ahaan loo isticmaalo tuubooyinka dareeraha caadiga ah ee Japan. Shuruudaha isku dhafka kiimikada waa: C: 0.25% max, Si: 0.35% max, Mn: 0.3% ~ 0.9%, P: 0.04% max, S: 0.04% max; sifooyinka farsamada waa in ay ahaadaan: xoogga xajinta: 370Mpa min, xoog dhalidda: 215Mpa min, elongation: 30%. Aad ugu eg GB/T8163 10#, labada heer waxay u baahan yihiin tijaabo isku mid ah (cadaadiska hydraulic iyo tijaabo aan burburin, tijaabin flaring), markaa labada waa la bedeli karaa midba midka kale.
Codsiga
Waxaa inta badan loo adeegsadaa in lagu sameeyo birta qaab dhismeedka kaarboon, birta qaab dhismeedka Alloy iyo qaabdhismeedka farsamada.

a.Marka lagu daro darajooyinka Q345A iyo Q345B, birta waa in ay ka kooban tahay ugu yaraan mid ka mid ah walxaha badarka la safeeyey ee Al, Nb, V, iyo Ti. Marka loo eego baahiyaha, alaab-qeybiyuhu wuxuu ku dari karaa hal ama in ka badan oo walxood oo la safeeyey. Qiimaha ugu badan waa inuu ahaadaa sida lagu qeexay shaxda. Marka la isku daro, Nb + V + Ti kama badna 0.22%b. Q345, Q390, Q420 iyo Q46O, Mo + Cr kama badna 0.30%c. Marka Cr iyo Ni ee fasal kasta loo isticmaalo hadhaaga, waxa ku jira Cr iyo Ni waa in aanay ka badnaan 0.30%; marka ay lagama maarmaan noqoto in lagu daro, waxa ku jira waa in ay buuxiyaan shuruudaha miiska ama ay go'aamiyaan alaab-qeybiyaha iyo iibsadaha iyada oo la tashanayo.d. Haddii alaab-qeybiyuhu uu hubin karo in waxa ku jira nitrogen uu buuxiyo shuruudaha shaxda, falanqaynta waxa ku jira nitrogen lama samayn karo. Haddii Al, Nb, V, Ti iyo walxo kale oo alloy ah oo leh hagaajinta nitrogen lagu daro birta, nuxurka nitrogen ma xaddidna. Nuxurka hagaajinta nitrogen waa in lagu qeexaa shahaadada tayada.e. Marka la isticmaalayo aluminium buuxa, wadarta aluminium ka kooban Alt ≥ 0020%. |
