Imibhobho yentsimbi engenamthungo idlala indima ebalulekileyo kwizicelo zoshishino, kwayeEN 10210kunye ne-EN 10216 ziinkcukacha ezimbini eziqhelekileyo kwimigangatho yaseYurophu, ezijolise kwiipayipi zentsimbi ezingenamthungo zokusetyenziswa kwesakhiwo kunye nokusetyenziswa koxinzelelo ngokwahlukeneyo.

Umgangatho we-EN 10210
Izinto kunye nokwakheka kwazo:
IEN 10210umgangatho usebenza kwiipayipi zentsimbi ezingenamthungo ezenziwe ngobushushu kwizakhiwo. Izinto eziqhelekileyo ziquka i-S235JRH, i-S275J0H,S355J2H, njl. Izinto eziphambili ze-alloy zezi zinto ziquka ikhabhoni (C), i-manganese (Mn), i-silicon (Si), njl. Ulwakhiwo oluthile luyahluka ngokwemigangatho eyahlukeneyo. Umzekelo, umxholo wekhabhoni we-S355J2H awudluli kwi-0.22%, kwaye umxholo we-manganese umalunga ne-1.6%.

Ukuhlolwa kunye neemveliso ezigqityiweyo:
EN 10210Imibhobho yentsimbi kufuneka ivavanywe ngokuqatha iimpawu zoomatshini, kuquka amandla okutsalwa, amandla okukhupha kunye novavanyo lobude. Ukongeza, uvavanyo lokuqina kwempembelelo luyafuneka ukuqinisekisa ukusebenza kwiindawo ezinobushushu obuphantsi. Imveliso egqityiweyo kufuneka ihlangabezane nobunzima obufunekayo kunye neemfuno zomgangatho womphezulu ezichazwe kumgangatho, kwaye umphezulu uhlala ungagqwali.

Umgangatho we-EN 10216
Izinto kunye nokwakheka kwazo:
Umgangatho we-EN 10216 usebenza kwiipayipi zentsimbi ezingenamthungo zokusetyenziswa koxinzelelo. Izinto eziqhelekileyo ziquka i-P235GH, i-P265GH, i-16Mo3, njl. Ezi zinto ziqulethe izinto ezahlukeneyo zokudibanisa. Umzekelo, i-P235GH inomxholo wekhabhoni ongadluli kwi-0.16% kwaye iqulethe i-manganese kunye ne-silicon; i-16Mo3 iqulethe i-molybdenum (Mo) kunye ne-manganese, kwaye inokumelana nobushushu okuphezulu.

Ukuhlolwa kunye neemveliso ezigqityiweyo:
Imibhobho yentsimbi ye-EN 10216 kufuneka idlule kuthotho lweenkqubo zokuhlola ezingqongqo, kubandakanya uhlalutyo lokwakheka kweekhemikhali, uvavanyo lwepropathi yoomatshini kunye novavanyo olungonakalisiyo (njengovavanyo lwe-ultrasonic kunye novavanyo lwe-X-ray). Umbhobho wentsimbi ogqityiweyo kufuneka uhlangabezane neemfuno zokuchaneka kobukhulu kunye nokunyamezela ubukhulu bodonga, kwaye uhlala ufuna uvavanyo lwe-hydrostatic ukuqinisekisa ukuthembeka kwawo kwiindawo ezinoxinzelelo oluphezulu.

Isishwankathelo
IEN 10210kunye nemigangatho ye-EN 10216 yemibhobho yentsimbi engenamthungo yeyemibhobho yentsimbi yokwakha kunye neyoxinzelelo ngokwahlukeneyo, egubungela iimfuno ezahlukeneyo zezinto zokwakha kunye nokwakheka. Ngokusebenzisa iinkqubo zokuhlola ezingqongqo kunye novavanyo, iimpawu zoomatshini kunye nokuthembeka kwemibhobho yentsimbi kuyaqinisekiswa. Le migangatho ibonelela ngesiseko esithembekileyo sokukhethwa kwemibhobho yentsimbi kwizicelo ezahlukeneyo zoshishino, iqinisekisa ukhuseleko kunye nokuzinza kweprojekthi.
