Ukuba ufuna ukwazi ulwazi oluthe kratya, olufana neekowuteshini, iimveliso, izisombululo, njl.njl., pqeshisanxibelelana nathi kwi-intanethi.
I-Tianjin Sanon Steel Pipe Co., Ltd. ngumthengisi wempahla. Ifektri yethu yempahla ikwiSixeko saseCangzhou, kwiPhondo laseHebei. Imithombo yethu ephambili yeempahla yileimibhobho yebhoyila, kwaye izixhobo ezimeleyoI-ASTM A335 P5/P11/P91/P92,I-ASME SA-106/SA-106MGR.B,GB/T 3087-200810#/20#. Izinto ezimele imibhobho yepayipi zeziI-API 5L,I-API 5CT, izinto ezimele imibhobho yokuqhekeka kwepetroliyamI-GB/T 9948ziyi-15MoG/12CrMoVG. I-GB/T 6479-2013 imele izinto ezi-10#/20#, iityhubhu zokutshintsha ubushushu i-SA179/SA210/SA192, njl.njl., iityhubhu zoomatshini i-GB/T 8162 zimele izinto ezi-10#/20#/Q345/42CrMo, i-EN10210 imele izinto ezi-S355JOH/S355J2H, iityhubhu zesilinda yegesi i-GB1 8248, zimele izinto ezi-34CrMo4/30CrMo.
Ukuthengwa kunye nekoteshini yepayipi yentsimbi yekhabhoni
Umbhobho wentsimbi yekhabhoni yimveliso esetyenziswa rhoqo kwaye ithengwa ngabathengi. Iinkcukacha eziqhelekileyo ziqukaI-ASTM A106 GRB, ububanzi bangaphandle yi-60-273mm, ubukhulu bodonga yi-SCH40-SCH80. Ngaphambi kokuba uthenge, kuyimfuneko ukucwangcisa iinkcukacha zeemfuno zabathengi kwaye ubuze amaxabiso kubathengisi. Abathengisi abakumgangatho ophezulu esisebenzisana nabo baquka iBaosteel, iHengyang, iTPCO, iAnhui Tianda, iLuli, iFengbao, njl.njl., kwaye sibeka phambili uluhlu lwezinto ezifumanekayo ukuqinisekisa impendulo ekhawulezileyo kwiimfuno zabathengi.
Ukuba umthengisi unikezela ngexabiso letyhubhu engenanto, kufuneka ukucubungula okongezelelweyo, okubandakanya ukuthutha impahla, iifizi zokucubungula kunye neefizi zokuhlola (ngokweemfuno zabathengi). Uvavanyo olusisiseko lubandakanya ububanzi bangaphandle, ubukhulu bodonga, umlinganiselo wobude, kunye nokuqinisekiswa kwefoto okanye ividiyo. Ukuhlolwa komntu wesithathu kunokucwangciswa ngokubambisana, kwaye zonke iifoto zepayipi yentsimbi zigcinwa kwindawo yokugcina ukuze zisetyenziswe.
Ukuthengwa kwemibhobho yentsimbi ye-alloy kunye neempawu zayo
Inkqubo yokuthenga imibhobho yentsimbi ye-alloy ifana neyemibhobho yentsimbi ye-carbon, kodwa ukusebenza kwezinto kwahlukile kakhulu. Intsimbi ye-carbon yenziwe kakhulu ngentsimbi kunye ne-carbon, ngexabiso eliphantsi kwaye ifanelekile kwimveliso enkulu, kodwa ayinabo ukuqina kwaye ithambekele ekuqhekekeni okuqhekekayo kumaqondo obushushu aphantsi. Intsimbi ye-alloy yongeza izinto ezifana ne-chromium, i-nickel, kunye ne-molybdenum ukuphucula ukumelana nokugqwala, amandla obushushu aphezulu, kunye nokumelana nokuguguleka. Umzekelo:
I-ASTM A335 P5, P9, P11, P22,I-P91
Ityhubhu yesilinda yegesiGB/T 18248-2021 34CrMo4, 37Mn
Sineetoni ezingama-20,000 zeetyhubhu ze-alloy ezikhoyo unyaka wonke ukuhlangabezana neemfuno ezahlukeneyo.
Amanqaku aphambili okuthengaimibhobho yeoyilekwayeimibhobho
Iipayipi zeoyile kunye neepayipi zisetyenziswa kakhulu kwiiodolo zobunjineli okanye ukuphinda zisetyenziswe. Iitoni ezincinci zikhethwa xa kuthengwa izinto ezithengiswayo, kwaye iiodolo ezinkulu zifuna ukuphononongwa kunye nokuhlelwa kweshedyuli. Iiodolo zobunjineli zihlala zichaza iimpawu kunye neemfuno zokubhida. Singabonelela ngamaxwebhu eziqinisekiso zokuxhasa ukubhida. Amatyala aphumelelayo agubungela iIndiya, iNepal, iVietnam, iBahrain, iPeru, iNigeria kunye namanye amazwe, anamava avuthiweyo kwimisebenzi yoku-odola kobunjineli.
Isishwankathelo
Ukuthengwa kwemibhobho yentsimbi engenamthungo kufuneka kuhambelane ngokuchanekileyo neemfuno zabathengi. Imibhobho yentsimbi yekhabhoni, imibhobho ye-alloy, imibhobho yeoyile kunye nemibhobho yomgca nganye ineempawu zayo. Sixhomekeke kubaboneleli abakumgangatho ophezulu kunye noluhlu oluninzi lwezinto ezikhoyo ukuqinisekisa ukuhanjiswa okusebenzayo, ngelixa sixhasa iinkonzo zokucubungula kunye nokuhlola ezenzelwe wena ukubonelela ngezisombululo zemibhobho yentsimbi ezinokuthenjwa kwiiprojekthi zehlabathi.
