About this concrete pump twin wall elbow, we have two types, one kind double layer elbow material is Q235+65Mn, inner wall bend through heat treatment, in order to improve the elbow hardness, so the toughness of the inner elbow is not so strong, but this kind of elbow is fragile, service life is about 30000cbm. Also have one kind double layer bend, the inner wall elbow is alloy steel, high wear resistence degree, delivery capacity is more longer, about 50000cbm. we usually exported this elbow to European countries.
