Inkonzo yobushushu obuphezulu yaseTshayina i-ASTM A106 A53 Gra/API 5L Grb/A179 A192 Udonga olungqindilili/Udonga oluNcinci lweCarbon olungenamthungo lwentsimbi/umbhobho ofakwe igalvanized
Isishwankathelo
Sizama ukugqwesa, sixhasa abathengi", sinethemba lokuba lelona qela liphezulu lentsebenziswano kunye neshishini elilawulayo kubasebenzi, ababoneleli kunye nabathengi, baqonda ukuba kufanelekile ukwabelana kunye nokuthengisa rhoqo kwiCarbon Steel Seamless Tube/Pipe, Ngaphandle koko, inkampani yethu inamathela kumgangatho ophezulu kwaye iindleko ezifikelelekayo, kwaye sikwabonisa iinkampani ezinkulu ze-OEM kwiimveliso ezininzi ezidumileyo Sijongene nokhuphiswano oluqatha lwemarike yehlabathi, siye sasungula isicwangciso sokwakha uphawu kwaye sahlaziya umoya we "inkonzo ejoliswe ebantwini kunye nethembekileyo", ngenjongo yokufumana ukuqatshelwa kwehlabathi kunye nophuhliso oluzinzileyo.
I-ASTM A106 GR. B Umbhobho wentsimbi ongenamthungo unomsebenzi omhle we-welding. Ngenxa yomxholo ophantsi we-C, akukho sakhiwo esinzima sokuqina ngenxa ye-welding, kwaye i-welded joint ine-plastiki efanelekileyo kunye nokuqina. Yonke inkqubo ye-welding inokufumana i-welding eyonelisayo ngaphandle kwamanyathelo akhethekileyo obuchwepheshe.
I-ASTM A106 GR. I-B kunye ne-20 # zifana ngokuqulunqwa kweekhemikhali kunye neempawu zoomatshini kwaye zihlala zitshintshwa enye kwenye, kodwa iyantlukwano ikhona, ngakumbi ngokumalunga neemfuno zokusetyenziswa okwandisiweyo. of GB8163 20 # ityhubhu yentsimbi yi -19℃, ngelixa i-ASMR B31.3 ichaza ukuba ubuncinane obusebenzayo be-A106 GR. I-tube yensimbi ye-B yi-29 ℃, kwaye kukho imeko yokungabikho kovavanyo lwempembelelo.Nangona kukho ukungafani kwiinkcazo zoyilo, isizathu esinzulu singumahluko kwinqanaba lokulawula umxholo we-Mn.Umvelisi akanakuqaphela ezi zandiso. , kodwa umthengi kufuneka awazi lo mahluko kwaye azise umenzi ngeemfuno ngexesha lokuthenga, kungenjalo iingxaki zinokuvela phantsi kweemfuno ezingqongqo.
Isicelo
Umbhobho wensimbi ongenamthungo wokusebenza okuphezulu kwe-ASTM A106, ilungele ukushisa okuphezulu
