GB/T8162 Steel Pipe

As a leading seamless steel tube manufacturer with over two decades of expertise, Tenjan produces GB/T 8162 seamless steel tubes that meet China’s national standard for structural applications while maintaining full compatibility with major international specifications. Our structural seamless tubes are engineered to deliver reliable performance in construction frameworks, mechanical components, and industrial structures, offering global clients a cost-effective alternative without compromising quality or technical requirements.

GB/T 8162 structural seamless tube inquiries should identify the structural or mechanical application, grade, standard edition, dimensions, length and delivery condition. Add straightness, surface, end machining and any fatigue- or impact-related requirements from the component drawing.

• Load case and downstream fabrication
• Outside diameter, wall, length and tolerances
• Heat treatment and mechanical properties
• Certificate, marking and traceability

Availability varies by grade, section, condition and order quantity. Proposed substitutions should be checked against the full design requirement; similar nominal strength does not establish equivalence for welding, impact service or heat treatment.

This product family is intended for structural and mechanical use rather than being selected solely as a pressure pipe. Typical projects include machinery, frames, cylinders and machined components. Provide the finished-part drawing so machining allowance and functional tolerances can be included in the tube plan.
