1. Soo bandhigid kooban oo ah dhuumaha qaab dhismeedka

Dhuumaha aan fiicnayn ee qaab dhismeedka (GB/T8162-2008) ayaa loo isticmaalaa qaab dhismeedka guud iyo qaab dhismeedka farsamada ee tuubada birta ah ee aan fiicneyn ayaa loo qaybiyaa noocyo kala duwan oo adeegsiyeedyo kala duwan.

Dhuumaha birta aan fiicnayn ee qaab dhismeedka (GB/T14975-2002) waa tuubo kulul (extruded, ballaadhiyay) iyo qabow-duuban (duubay) tuubo aan fiicnayn oo ka samaysan birta aan fiicnayn ee loo isticmaalo kiimikada, batroolka, dunta, caafimaadka, cuntada, mashiinnada iyo warshadaha kale, tuubooyinka u adkaysta daxalka iyo qaybaha iyo qaybaha dhismaha.

GB/T8162-2008 (tuubo aan kala go 'lahayn ee qaab dhismeedka) waxaa inta badan loo isticmaalaa qaab dhismeedka guud iyo qaab-dhismeedka farsamo.Its wakiilka (brand): carbon steel 20, 45 steel, Q235, steel alloy Q345, 20Cr, 40Cr, 20CrMo, 30-35CrMo, 42.

Dhuumaha birta ah ee aan cillad lahayn

Sababtoo ah habka wax-soo-saarku wuu ka duwan yahay, waxay u qaybsan tahay duub kulul (extruded) tuubo bir ah oo aan fiicneyn iyo qaboojiye (duubay) tuubo bir ah oo laba nooc ah.

A. Dulmarka socodka habka

Wareegid kulul (tuubo bir ah oo aan fiicneyn) : bir tuubo wareeg ah → kuleyl → daloolin → rogo saddex duuban, duubid joogto ah ama extrusion → tuubo xariif ah → cabbirka (ama yaraynta)

Sawirka qabow (rogid) tuubo bir ah oo aan fiicneyn: tuubo wareeg ah → kuleyl → dalool → ciwaanka → xinjirowga → pickling → saliid (salin naxaas ah) → sawir qabow badan oo baas ah (duubid qabow)
