Imibuzo Evame Ukubuzwa – Ipayipi Eli-ERW Elishiselweyo
Q1: Yini umehluko phakathi kwe-ERW nepayipi elingenamithungo?
A: ERW – umthungo owenziwe ngomshini, izindleko eziphansi, ezifanele izicelo ezijwayelekile. Okungenamithungo – akukho umthungo wokushisela, isilinganiso esiphezulu sengcindezi, izindleko eziphakeme.
Umbuzo 2: Ingabe ipayipi le-ERW lifanele izicelo zengcindezi ephezulu?
Impendulo: Yebo – emapayipini aphakathi nendawo kuya kwaphezulu (kufika ku-API 5L X70). Emapayipini anomfutho ophakeme kakhulu, kunconywa i-seamless.
Umbuzo 3: Yisiphi ubukhulu obukhulu obutholakalayo ngepayipi le-ERW?
A: 256mm OD ejwayelekile. Izinhlobo ezinkulu ezingafika ku-610mm ziyatholakala uma kucelwa.
Umbuzo 4: Ingabe umthungo wokushisela uphathwe ngokushisa?
Impendulo: Yebo – amapayipi amaningi e-ERW adlula ekwelashweni ngokushisa ngemuva kokuhlanganiswa ukuze kukhululwe ingcindezi futhi kuqiniswe indawo eyenziwe ngayo.
Q5: Ingabe ipayipi le-ERW lingasetshenziswa emishayweni kawoyela negesi?
A: Yebo – Amapayipi E-API 5L ERW asetshenziswa kakhulu ekudlulisweni kukaphethiloli negesi, ikakhulukazi izigaba ze-X42, X52, X65.
Q6: Ingabe ipayipi le-ERW lilungele i-galvanizing?
A: Yebo – Imishudo ye-ERW ivamise ukugcotshwa ngoshizi olushisayo emapayipini amanzi negesi.
Umbuzo 7: Ingabe iphayiphu le-ERW lingafakwa intambo?
A: Yebo – Amapayipi e-ERW angalungiswa ngemithambo ye-NPT noma ye-BSP ukuze axhunyaniswe ngomshini.
Umbuzo 8: Ingabe uhlinzeka ngokuhlola komuntu wesithathu?
A: Yebo. I-SGS, i-BV, i-TUV, noma noma iyiphi i-ejensi ecaciswe yikhasimende.
Umbuzo 9: Ingabe ninikeza amasampula amahhala?
A: Isampula engu-30cm iyatholakala ngobukhulu obujwayelekile. Kukhona imali yokuthumela.
