Indandatho ye-Metallic VSP, ebizwa nangokuthi indandatho ye-arc yangaphakathi, indandatho ekhethekile kakhulu, yenziwe nge-carbon steel, insimbi engagqwali, i-titanium alloy, i-aluminium alloy, i-alloy yethusi nezinto zensimbi engagqwali.Izindandatho ze-Metallic VSP zine-symmetry yejometri enengqondo, i-arc yangaphakathi igoqwe ngokulinganayo eduze kwe-axial direction futhi ithathelwa indawo ngokushintshana okuhleliwe.Lo mklamo unikeza indawo eqhubekayo yokungabi nalutho okuphezulu kakhulu nokusabalalisa ngokulinganayo.
Indandatho ye-Metal VSP inezici zodonga oluncane, isilinganiso esikhulu se-void, ukugeleza okuphezulu, umthamo, ukwehla kwengcindezi ephansi nokusebenza kahle kokuhlukana.Ngakho-ke uhla lwayo lokusebenza lubanzi kakhulu, okomisa, ukumunca, ukupholisa kanye nokuvuselela umbhoshongo embonini ye-metallurgic yamakhemikhali, igesi yamalahle kanye nokuhlukaniswa komoya.
