Outside Diameter : 4,00; 4,76; 6,35; 8,00 mm
Wall Thickness: 0,7 mm.
Notes:
- Steel grade: 08Al.
- The tubes are delivered zinc-coated or "black" in coils.
- The tubes of other dimensions can be produced by agreement:
OD: 4.0 - 8.0 mm with WT: 0.6 - 0.7 mm (excepting size 8.0 x 0.6 mm).
- Leak-proofness of tubes is checked by pneumatic pressure of 50 bars (dry air or nitrogen).
- High cleanness of internal surface (washed residue is not more than 0.1 g/m2) allows use of these steel tubes in refrigerators with ozone freandly coolants.
