| Standard Tubing, Capillary and Rodding |
| BOROSIL® brand glass tubing and rodding are very widely used for a variety of applications. Made from low thermal expansion borosilicate glass, its intrinsic qualities of resistance to physical and chemical attack and
ability
to stand thermal shock make it an ideal material of
construction
for scientific and laboratory apparatus, for industrial applications like syringe manufacture, gauge glasses, photo printing cylinders, petromax lantern globes, explosion-proof lighting covers and for fabrication of
chemical
process plant and piping. |
| BOROSIL® Brand Tubing is drawn on fully automatic machines which permit close
tolerances
on dimensions. These also undergo careful and strict quality control. A large and comprehensive range of tubing in diameters from 4mm to 163mm in light, medium and heavy wall is available ex-stock. |
| Capillary bore tubing and rodding are also available. Rigid tolerance tubing for the manufacture of hypodermic syringes is also offered. These are suitable for grinding and shrinkage
processes
for syringe manufacture. |
| We offer tubing (light, medium and heavy wall) in dimensions as required by International Standards
Organization
to comply generally with ISO/4803. |
| |
| Gauging/Dimension Control |
| Outside diameter when specified, all outer diameters at any point on a piece of tubing or rodding will be within the tolerances specified. These
tolerances
include out of round (ovaity). |
| Inside diameter when specified, all inner diameters at any point on a piece of tubing or rodding will be within the tolerances specified. These
tolerances
include out of round (ovality). |
| Wall thickness - All points at each end of a piece will be within the wall
tolerances
specified. Siding is included. |
| Lengths - For all standard lengths, a tolerance of ± 50mm is specified. |
| |
| Tubing/Rodding lengths |
| All tubing, capillary and rodding comes with standard lengths of 1500 mm. |
| Special sizes |
| BOROSIL® brand tubing and rodding can be manufactured to sizes and tolerances not listed. Any order for special sizes will be subject to the following -- |
- Minimum order for 1000 kg. Variation in supply can be ± 20%.
- The specifications should include diameter, wall thickness, length and their tolerances in mm and the same should have been confirmed by us.
