Tolerances for standard precision tubes

The tolerances for precision tubes align with dimensional tables specified in industry standards. Typically, the accepted deviation for the outside diameter (OD) is less than 0.5% in processes without heat treatment. However, for heat-treated tubes, tolerance values are contingent on the relationship between wall thickness and tube diameter (WT/OD) and may be comparatively larger, sometimes even doubling.

In terms of the outside diameter (OD), circularity deviation is factored into the allowed tolerance. For orders based on wall thickness, the acceptable tolerance is set at 10% of the wall thickness. It’s important to note that the eccentricity of a precision tube is already considered within the wall thickness tolerance.

Length of the standard precision tubes

The length of standard precision tubes is a critical parameter in meeting diverse industrial requirements. The maximum standard length for these tubes is set at 18 meters, providing flexibility and adaptability to different project specifications.

Types of Supplied Lengths:

1. Random Length: Typically falls within the range of 3 to 7 meters, with an extended option up to 9 meters. This allows for versatility in applications requiring varied tube lengths.
2. Fixed Length: Precisely controlled with a tolerance of ± 500 mm, ensuring uniformity and ease of handling during installation and fabrication processes.
3. Exact Length: Tubes can be supplied with exact lengths, with a specified agreement on the permissible deviation (– 0 / + x mm). This tailored approach allows for precise customization to meet specific project requirements.
4. Cut Tubes: For enhanced convenience, tubes can also be supplied as cut tubes, streamlining the manufacturing and assembly processes.

Standard Precision Tube Testing

Precision tubes undergo rigorous testing to meet stringent industry standards, ensuring their integrity and performance. The testing procedures can be categorized into mandatory and optional assessments.

Mandatory Testing:

1. Cast/Chemical Analysis: Verifies the composition of the tube materials, essential for meeting specified standards and ensuring quality control.
2. Tensile Test: Measures the tube’s mechanical properties, providing insights into its strength and durability under various conditions.
3. Dimensional Inspection: Ensures the precision tubes adhere to specified dimensional standards, crucial for seamless integration into diverse applications.
4. Visual Inspection: Thorough examination of the tube surface, detecting any visible defects or irregularities that may impact performance.

Optional Testing:

1. Flattening Test or Drift Expanding Test: Evaluates the tube’s deformability and resistance to flattening or expanding forces, crucial in applications with varying pressures.
2. Roughness Measurement NDT: Identifies longitudinal defects by assessing the tube’s surface roughness, enhancing quality control measures.
3. Eddy Current Testing: Utilizes electromagnetic induction to detect cracks, corrosion, or other anomalies in the tube material.
4. Stray Flux Testing: Assesses magnetic permeability, identifying potential issues such as cracks or discontinuities in the tube material.
5. Ultrasound Testing: Uses high-frequency sound waves to inspect the internal structure of the tube, ensuring the absence of defects that might compromise its performance.
6. Leakage Test by Eddy Current (EN 10246-1): Provides a non-destructive proof of tightness, ensuring the tube’s resistance to leaks under various conditions.
