    test Izidingo

    Flattening test

    ngemibhobho Steel kunye ubukhulu enkulu engaphandle kwe-22 mm ukuya kwi-400 mm, kunye nodonga ubukhulu ngaphezulu kwe-10 mm kufuneka bangenele uvavanyo flattening. Emva kokuba iisampula atshabalalisa

    ukugoba test

    ngemibhobho Steel kunye ubudeki engaphandle umkhulu kwe-22 mm kufuneka bangenele uvavanyo ukuvumela. I angle ukugoba yi 90o. Le radius ukugoba ngokuphindwe 6 sangqa kumphandle le tube.After ngentsimbi ayeguqa isampulu, akukho ehlola okanye amathanda ukuba bavele kwi isampulu.

    iimviwo kokukhulu

    Kuba ngemibhobho steel wenza ngqo billets ngokuqhubekekayo baphose okanye etshe zentsimbi, iqela ukunika kufuneka ukuqinisekisa ukuba akukho amatshatshazi amhlophe, ubumdaka, sub-umphezulu amaqamza, amabala yaba lukakayi okanye emva komnye emnqamlezweni-somhlathi acid zifakwa izihlunu kokukhulu le billet okanye tube kuhlinzwa.

    ukuhlolwa Non-umonakalo

    Ngokutsho isicelo iqela ngenkani, nto leyo ke thethwane phakathi kwamaqela ukunika kwaye zenziwe futhi kuboniswe kwisivumelwano, Ubhaqo obubangela cuke ukuba ngamnye ukwenziwa ngenxa kwimibhobho yentsimbi. I siphene longitudinal ncwadana Manual of reference isampuli ityhubhu kufuneka ihlangabezane neemfuno post-ukuhlolwa ngokulikholo grade C8 abakhankanywe ku GB / T 5777-1996.
