High-Quality Oversized Fused Quartz Tubes from China Suppliers | Factory for High-Temperature Applications

The specification table covers outer diameters ranging from 200 mm up to 1000 mm, providing a wide selection to suit various industrial and structural applications.

As the outer diameter increases, the standard wall thickness range also increases proportionally. For example, a 200 mm diameter pipe has a wall thickness of 6–12 mm, while a 1000 mm diameter pipe requires 25–45 mm, ensuring adequate structural integrity at larger sizes.

Most sizes (200–600 mm outer diameter) are available in standard lengths of 1000–2000 mm. Larger diameters (700–800 mm) are limited to 1000–1800 mm, and the largest sizes (900–1000 mm) are available in 1000–1500 mm lengths, reflecting manufacturing and handling constraints.

Larger pipes are more challenging to manufacture with tight precision due to the greater material volume and thermal effects during production. As a result, tolerance ranges widen with increasing diameter — from ±2.0～±3.0 mm at 200 mm up to ±12.0～±15.0 mm at 1000 mm — while still meeting industry standards.

The table lists standard wall thickness ranges for each diameter. Custom thicknesses beyond these ranges may be available depending on specific project requirements and material capabilities. It is recommended to consult with the manufacturer directly for non-standard specifications.

Wall thickness tolerances define the acceptable variation from the nominal wall thickness during production. They are critical for ensuring consistent pressure resistance, structural performance, and compatibility with fittings or installation systems. Tighter tolerances are applied to smaller pipes, while larger pipes carry slightly wider tolerance bands.
