ULuhlu lwamaxabiso aphantsi loMbhobho woMvelisi kunye neTube yeKhabhoni ye-Iron Oval Shape Steel yolwakhiwo olungenamthungo lombhobho we-ERW umbhobho
Inkcazelo emfutshane:
Umbhobho okhethekileyo wensimbi ongenamthungo ligama eliqhelekileyo lemibhobho yentsimbi engenamthungo kunye nezinye iimilo ezinqamlezileyo ngaphandle kwemibhobho engqukuva.Ngokweemilo ezahlukeneyo ezinqamlezileyo kunye nobukhulu bemibhobho yentsimbi, zinokwahlulwa zibe yimibhobho yentsimbi elinganayo emilise okwemilo eyodwa (ikhowudi D), ubukhulu bodonga obungalinganiyo imibhobho yentsimbi engenamthungo (ikhowudi BD) kunye nedayamitha ekhethekileyo. -imibhobho yentsimbi engenamthungo (ikhowudi BJ).
Impahla yethu yamkelwa ngokubanzi kwaye ithembekile ngabasebenzisi kwaye inokuhlangabezana nokutshintsha ngokuguquguqukayo iimfuno zemali kunye nezentlalo zoLuhlu lwamaxabiso atshiphukileyo kuMvelisi wePipe kunye neTube yeCarbon Iron Oval Shape Steel Seamless Structure Pipe ERW Pipe, urhwebo lwethu luthandwa kakhulu kwihlabathi liphela njengolona lukhuphisanayo. ixabiso kunye nelona ncedo lwethu emva kokuthengiswa koncedo lwabathengi.
Impahla yethu yamkelwa ngokubanzi kwaye ithembekile ngabasebenzisi kwaye inokuhlangabezana nokutshintshana ngokweemfuno zemali nezentlaloUmbhobho weNtsimbi weMilo ekhethekileyo yaseTshayina kunye nombhobho wentsimbi, Ngeqela labasebenzi abanamava nabanolwazi, imarike yethu igubungela uMzantsi Merika, i-USA, uMbindi Mpuma, kunye noMntla Afrika.Abathengi abaninzi baye baba ngabahlobo bethu emva kwentsebenziswano elungileyo nathi.Ukuba unemfuno kuyo nayiphi na imveliso yethu, khumbula ukudibana nathi ngoku.Sijonge ukuva kuwe kungekudala.
Umbhobho wensimbi owenziwe ngokukhethekileyo unokulungelelanisa ngakumbi ubungcali beemeko zenkonzo, ugcine isinyithi kunye nokuphucula imveliso yabasebenzi yeengxenye zokuvelisa.Isetyenziswa kakhulu kwinqwelomoya, kwimoto, kulwakhiwo lweenqanawa, koomatshini basemigodini, koomatshini bezolimo, ekwakhiweni, kwilaphu nakwibhoyila.Umzobo obandayo, i-welding yombane, i-extrusion, i-hot rolling kunye nokunye iindlela zokuvelisa imibhobho ekhethekileyo, phakathi kwayo indlela yokudweba ebandayo isetyenziswe ngokubanzi.
Imibhobho yentsimbi eneprofayili, imibhobho yentsimbi eneprofayili yenziwa ngokugoba, eyaziwa ngokuba kukugoba.Kukho iindidi ezimbini zokugoba kwimibhobho yentsimbi enokwakheka okukhethekileyo, enye kukugoba okuyinyaniso kwaye enye kukugoba okungenanto.
Yinkqubo yeendlela ezimbini ukuba umbhobho wesquare ogobileyo wokwenyani udityaniswe, kwaye emva koko ukugoba okugobileyo, iindonga zangaphakathi nangaphandle zemibhobho yerola yangaphakathi kunye neyodwa kunye nemibhobho yentsimbi ekhethekileyo ihlanganiswe.Uncedo lokugoba lokwenyani lwemibhobho yoxande kukuba ukugoba okuqinileyo kuya kuba kuncinci, kwaye i-engile echaneke ngakumbi yeprofayili yemibhobho yentsimbi inokwakheka ukuba nje uhlobo lomqulu lusetyenziswa ngokuchanekileyo kwaye umbhobho wentsimbi wangaphakathi wenziwa ngokuchanekileyo. ixesha lemveliso.
Ukugoba okukhawulezileyo kuneziphene ezithile.Ixesha eliphambili lokwelula liya kubangela ukuba umbhobho wensimbi ube mncinci.Ukugoba kwangempela kuya kubangela ukuba umbhobho wexande ugobe.Ukugoba ukugoba kweemveliso zezolimo kuya kubangela ukuba ubude becala lokugoba kwicala lobude bombhobho wentsimbi obukhethekileyo bube bufutshane, kwaye umxholo wesinyithi uya kuncitshiswa ngenxa yokwelula.
Kwimveliso yokugoba engenanto imibhobho yoxande, iirola zangaphandle kunye neendonga zangaphandle zesikwere kunye nemibhobho yentsimbi ekhethekileyo, kunye nokugoba kwentsimbi, igophe lokugoba lombhobho wentsimbi liya kuvelisa uxinzelelo oluthile, ngoko ke impembelelo yoxinzelelo, ukuguquguquka kobude. Ubude belayini egoso-goso, kunye nentsimbi egotywe ngumbhobho woxande iya kuba kukugoba komoya ongqindilili, ukucinezelwa okanye ukujiya.
Ezi ndlela zimbini zokuvelisa, iindlela ezimbini ezisisiseko zokuvelisa umbhobho woxande kunye nesikwere kunye nokwakhiwa kombhobho wentsimbi owenziwe ngendlela ekhethekileyo, kwaye uqwalaselo lwenkqubo olufanelekileyo lukhethwa ngokweemfuno zeemveliso ezahlukeneyo.Kufuneka kuqatshelwe ukuba xa yoluliwe kwaye icinezelwe, impembelelo kumgangatho wemveliso, okanye ukuguqulwa kwesikwere kunye neetyhubhu ezixande.
