UMbhobho WOKWAKHIWA OKUNGATHUMELI UMBHAYIBHI ONGATHUNGEYO WOKWAKHIWA
Inkcazo
Umbhobho wensimbi wesakhiwo unombhobho wentsimbi eshushu-eqengqelekayo kunye ne-welded steel tube.I-tube yensimbi engenamthungo yesakhiwo yahlulwe ibe ziindidi ezimbini ngokuhambelana nemiqathango "ye-tube yensimbi engenamthungo yesakhiwo" (GB / t8162-2008) : i-hot rolling (i-hot rolling) i-extrusion, i-extrusion) kunye nomzobo obandayo (ukuqengqeleka)Idayamitha yangaphandle yombhobho wentsimbi etsalwa ngokubanda yi-5-200mm kwaye ubukhulu bodonga yi-2.5-12mm.Umbhobho wentsimbi odityanisiweyo wenziwa ngepleyiti yentsimbi okanye umcu wentsimbi emva kokugonywa kunye nokwenza, enokuthi yahlulwe ibe ngumbhobho wentsimbi odityanisiweyo othe tye kunye nombhobho wentsimbi ojikelezayo. -12.7mm ngokulandelanayo, eya kuhambelana nemimiselo ye-GB / t3793-2008. Umbhobho wensimbi odibeneyo wokuthuthwa kwamanzi oxinzelelo oluphantsi ubizwa ngokuba yipayipi eqhelekileyo, eyaziwa ngokuba yi-clark pipe.Inkcazo ibonakaliswe kwi-mm ye-diameter ye-nominal, ekufuneka ihambelane nemimiselo ye-GB / t3091-2008 yokuthutha umbane ophantsi.

Ukupakisha&Ilayisha
Ipakethe ehlanganisiweyo
Kwi-bundle yetyhubhu yentsimbi iya kuba yinto enye kwi-batch number.ibakala lentsimbi kunye ne-specification.intsalela yetyhubhu engaphantsi kwesinye kufuneka ibotshelelwe kwimiyanda emincinci.
Ubunzima bomthwalo ngamnye kufuneka bube ngaphantsi kwe-50kg. Ubunzima obukhulu abukwazi ukudlula i-80kg ye-bundle Ukuba kukho iimfuno ezikhethekileyo.
Xa ubude betyhubhu yensimbi bukhulu okanye bulingana ne-6m. kunye neebhanti zokubopha ubuncinane ezi-8 kwi-bundle nganye, yahlulwe ngamaqela ama-3 kunye ne-3-2-3
Xa ubude betyhubhu yentsimbi bungaphantsi kwe-6mand inyanda nganye ibotshelelwe ubuncinane amaqhina ama-5 kwaye yahlulwe ngamaqela ama-3 angama-2-1-2.
Xa ubude bombhobho bukhulu okanye bulingana ne-3m, kwaye i-bundle nganye iboshwe ubuncinane kunye namaqela angama-3. Ihlulwe ngamaqela ama-3, i-1-1-1 ibonise ngezantsi.
Iphakheji yebhokisi yomthi
Ibhokisi yomthi ilungele ukuqengqeleka okubandayo okanye ukuzoba ityhubhu yentsimbi engenamthungo epholileyo, ityhubhu yentsimbi epholileyo ephothiweyo.Xa ububanzi bangaphandle bombhobho wentsimbi bukhulu okanye bulingana ne-10mm, ubunzima obukhulu besitya kufuneka bube yi-50kg.Xa i-diameter yangaphandle yombhobho wentsimbi ingaphantsi okanye ilingana ne-10mm, ubunzima besikhongozeli kufuneka bube yi-30kg.
