Pipes manufacture

The technologies of pipes manufacture from the following materials are widely used:

  • aluminum alloys: 6.0-80.0 mm and wall thickness 0.5-2.5 mm;
  • titanium alloys: 10.0-42.0mm and wall thickness 0.5-1.2 mm;
  • stainless steel: 3.0-50.0 mm and wall thickness 0.3 - 1.5 mm;
  • copper: 5.0-10.0 mm and wall thickness 0.5 - 1.5 mm;

JSC “KnAAPO” executes the following actions:

  • cutting of tubing;
  • chemical treatment of tubing and its elements;
  • bending of tubing:
    manual bending;
    by specialized machine TG -1;
  • by NC machine:
    TGSP-24 - up to 24mm;
    TGSP-40 - up to 40mm;
  • welding of the tubing:
    soldering of tubing by HDTV-sets;
    soft soldering of tubing (on a base of tin);
    hard soldering of tubing (on a base of silver);
    automatic welding of capacitances;
    spot and roller welding (manholes of different dimensions);
  • manufacture of tubing elements:
    expansion of a tube on the SIT-1specialized machine;
    extraction of T-branches on the SIT-2specialized machine;
    steeply curved fittings - on PGFP 20/100;
  • ball connections - on universal press;
  • rolling-off and expansion of tubes into nipple;
  • strength and leakage test of all spectrums of products, its packaging.

The enterprise bought the RB 90 CNC Swiss-made tube bending machine tool for bending of 25-90 mm tubes.
