I .Brief introductio structurarum pipe

Fistula inconsutilis ad structuram (GB/T8162-2008) adhibetur pro structura generali et structura mechanica organi inconsutilem. Seamless chalybeis tubus in varios usus dividitur.

Fistula immaculata inconsutilem ad structuram (GB/T14975-2002) est calidum volvitur (extruditur, dilatatur) et frigidum extractum (volutum) inconsutilem fistulam ex ferro immaculato adhibitam in chemicis, petrolei, textilibus, medicinis, cibis, machinationibus ac aliae industriae, fistulae corrosio-resistentes et partium structuralium et componentium.

GB/T8162-2008 (tibia inconsutilis ad structuram) maxime adhibetur ad structuram generalem et structuram mechanicam. Eius materia repraesentativa (ensis) : chalybe carbonis 20, 45 chalybs, Q235, mixtura ferri Q345, 20Cr, 40Cr, 20CrMo, 30-35CrMo , 42CrMo et reliqua.

Seamless ferro pipe

Propter processum fabricationis diversum, in fistulam calibem (extrusam) inconsutilem chalybem inamabilem et frigidum tubus ferri (volutus) inconsutilem ferri duo genera divisum est. Fistula Cold-ducta (rolled) in fistulam circularem dividitur, et fistulam specialem in duas. genera earum.

A.Overview processus influunt

Calidum volubilem (tubus ferro inconsutilem extrusam) : tubum rotundum subcinericium → calefactio → perforatio → tres-volubilis crux volubilis , continuus volubilis vel extrusio → tubus denudatio → inspectionem ( vel reductio ) → refrigeratio → tubulum blank → tubulum aquae pressionis test → erigens ( vel defectus . deprehensio) → Intendens → Reposita.

Frigidus tractus (volubilis) inconsutilem ferro tubo: rotundo tubo conata → calefactio → perforatio → petentis → furnum → spicarum → unctionem ( aeneam ) → multi-transitu frigoris tractus (frigus volubilis) → blank fistula → calor curatio → corrigens aqua pressura test → ( Vitium deprehensio ) → Repono → Repono.
