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 oo duuban (la fidiyay, la ballaariyay) iyo qabow-duuban (duubay) tuubo aan bilaa lahayn oo ka samaysan bir aan fiicnayn oo loo isticmaalo kiimikaad, batroolka, dunta, caafimaadka, cuntada, mishiinada iyo warshadaha kale, tuubooyinka u adkaysta daxalka iyo qaybaha dhismaha iyo qaybaha.

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

Dhuumaha birta ah ee aan cillad lahayn

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

A. Dulmarka socodka habka

Wareegid kulul (tuubo bir ah oo aan fiicneyn) : tuubo wareeg ah → kululaynta → daloolin → rogo saddex duuban, duubid joogto ah ama extrusion → tuubo xariijimo → cabbir (ama yaraynta) → qaboojinta → tuubo banaan ogaanshaha) → calaamadaynta → kaydinta.

Sawir-qabow (rogid) tuubo bir ah oo aan lahayn: tuubo wareegsan (helidda cilladda) → calaamadaynta → kaydinta.
