❓ Frequently Asked Questions
Q
What outer diameter range is available for these pipes?
The pipes are available in outer diameters ranging from 200 mm to 1000 mm, covering a wide range of industrial and infrastructure applications. Custom sizes outside this range may also be available upon request.
Q
How are the outer diameter tolerances determined?
Outer diameter tolerances increase proportionally with pipe size. For example, a 200 mm pipe carries a tolerance of ±2.0～±3.0 mm, while a 1000 mm pipe has a tolerance of ±12.0～±15.0 mm. These tolerances follow standard manufacturing guidelines to ensure fit and performance.
Q
What wall thickness options are available?
Wall thickness varies by pipe diameter. Smaller pipes (200 mm) start at 6～12 mm, while larger pipes (1000 mm) offer wall thicknesses of 25～45 mm. The range allows selection based on pressure requirements, load conditions, and application environment.
Q
What are the standard lengths available?
Standard lengths range from 1000 mm to 2000 mm for pipes up to 600 mm in diameter. Larger pipes (700–800 mm) are available up to 1800 mm, and pipes of 900–1000 mm diameter are available up to 1500 mm in length, reflecting practical handling and transportation considerations.
Q
Can custom specifications be ordered beyond the listed tolerances?
Yes. The values listed represent standard manufacturing tolerances. For projects requiring tighter tolerances or special dimensions, custom orders can be arranged. Please contact our technical team with your specific requirements for a tailored solution.
Q
Why does the standard length decrease for larger diameter pipes?
Larger diameter pipes are heavier and more difficult to handle, transport, and install. Reducing the standard length for pipes with diameters of 700 mm and above helps ensure safer logistics, easier on-site handling, and compliance with transportation weight limits without compromising structural integrity.
