Ungayenza njani i-SML Pipe Tensile Test ngokwe-EN877?

Kwiimveliso ezenziwe nge-spheroidal graphite cast iron, amandla okuxinana kufuneka alinganiswe ngokuhambelanaEN 598:2007+A1:2009, 6.3. Kwimveliso ezenziwe ngentsimbi engwevu okanye naluphi na olunye uhlobo lwentsimbi eyosiweyo, ukumisela amandla okuxinana kuya kwenziwa ngokuhambelana no-2 okanye u-3.

Chaza amandla okutsalwa kwimibhobho yentsimbi engwevu kunye nokufakelwa kwayo

1. Iisampulu

Ukuze kufunyanwe iziphumo ezimele kangangoko kunokwenzeka iimveliso ezigqityiweyo, uvavanyo lokuxinana kufuneka lwenziwe kwiisampuli:nokuba ithathwe kwiImibhobho ye-SMLokanye izixhobo zombhobho wesinyithi. Isampulu kufuneka isikwe ngokuhambelana nomgca wombhobho okanye isixhobo; okanye kuphela kwiindawo zokufaka, ezivela kwiziqwenga zovavanyo ezidityanisiweyo, ezidityanisiweyo ngaxeshanye nezixhobo zokufaka.

Isiqwenga sovavanyo esisikiweyo kwisampulu masihambelane neMifanekiso, kwaye ukuba sivela kwiziqwenga zovavanyo ezidityanisiweyo ngokwahlukeneyo, sinokuba sithe tyaba endaweni yokuba sigobe.

2. Izixhobo kunye nendlela yovavanyo

Umatshini wokuvavanya kufuneka ube nezixhobo ezifanelekileyo ukuvumela ukusetyenziswa kwamandla okuvavanya ngaphandle kokutyibilika.
Umatshini wokuvavanya uya kukwazi ukuvelisa amandla aneleyo ukuqhekeza iziqwenga zovavanyo ngelixa ebonisa umthwalo osetyenzisiweyo.
Ukuchaneka komatshini wokuvavanya kufuneka kuhambelaneI-EN IS0 6892-1:2019, Isiqendu 9.
Isantya sokusetyenziswa komthwalo masibe njalo kangangoko ngokuhambelanaI-EN IS0 6892-1:2019, Isiqendu 10.
Amandla okutsalwa kufuneka abalwe ngokwahlula amandla aboniswe ekuqhekekeni ngendawo yecandelo lokuqala lokuwela lesixhobo sovavanyo. Icandelo eliwelayo (ububanzi kunye nobukhulu) kufuneka lilinganiswe ngokuchanekileyo kwe-0,1 mm ngaphambi kovavanyo.

3. Ukunyaniseka kovavanyo lwamandla okuqina

Uvavanyo luvakaliswa lusebenza ukuba le miqathango ilandelayo iyazalisekiswa:

• kwimibhobho: umyinge wamaxabiso amathathu athathwe kwimveliso yosuku olunye kufuneka ubuncinci ibe yi-200 MPa kwaye ubuninzi bexabiso elinye bunokuba phakathi kwe-180 MPa kunye ne-200 MPa;
• kwizixhobo zokufakelwa: onke amaxabiso kufuneka abe yi-150 MPa ubuncinane

Iziphumo zoVavanyo oluThambileyo
