    Isishwankathelo

    Sigcina ukuphuculwa kunye nokugqibelela ukuthengisa kunye nenkonzo yethu. Kwangaxeshanye, senza umsebenzi ngenkuthalo ukwenza uphando kunye nokuphuculwa kweMechanical Steel Pipe, Ngenzuzo yolawulo lweshishini, ishishini belisoloko lizibophelele ekuxhaseni amathemba okuba yinkokeli yangoku yentengiso kumashishini abo. Ukuzinikela kusoloko kusisiseko kuthumo lwethu. Besisoloko sihambelana nokusebenzela abathengi, ukudala iinjongo zolawulo lwexabiso kunye nokuthobela ukunyaniseka, ukuzinikela, ingcamango yokulawula eqhubekayo.

    Isicelo

    Isetyenziswa ikakhulu kumatshini kwaye isetyenziselwa ukwenza iisilinda zerhasi.ibandakanya ikhabhoni kunye nentsimbi yensimbi engenamthungo, kwaye igquma zombini iityhubhu yoomatshini engenamthungo eshushu-egqityiweyo kunye netyhubhu yomatshini egqityiweyo engenamthungo ngokobukhulu ukuya kunye nokubandakanya i-12 3⁄4 ngaphakathi. (323.8 mm) ngaphandle kwedayamitha yeetyhubhu ezingqukuva ezinobunzima bodonga njengoko kufuneka.

    Imfuneko yoVavanyo

    1.Uvavanyo lobunzima
    Xa imida yokuqina ifuneka, umvelisi kuya kuboniswana naye. Ubulukhuni obuqhelekileyo zidweliswe kwiThebhile .Xa kucacisiwe, uvavanyo lobunzima luya kwenziwa kwi-1% yeetyhubhu.

    2.Tension Tests
    Xa iipropathi zokuqina zifuneka, kuya kuboniswana nomvelisi. Iipropathi eziqhelekileyo zokuqina kwamanye amabakala aqhelekileyo kunye neemeko zobushushu zidweliswe kwitheyibhile.

    3.Uvavanyo olungonakalisiyo
    Iindidi ezahlukeneyo zovavanyo lwe-ultrasonic okanye i-electromagnetic engasebenziyo ziyafumaneka. Uvavanyo oluza kusetyenziswa kunye nemida yokuhlola iya kusekwa ngumenzi kunye nesivumelwano somthengi.

    4.Uvavanyo oluvuthayo
    Xa kukho iimfuno ezikhethekileyo zokucoceka kwensimbi, iindlela zokuvavanya kunye nemida yokwamkelwa ziya kusekwa ngumenzi kunye nesivumelwano somthengi.
