Seamless Rectangular Steel Pipe Ideal for Piping Systems and Conduit Installations in Construction

Engineered for precision and durability, our seamless rectangular steel pipes deliver exceptional performance in demanding construction environments. Manufactured by Hunan Yige Special Steel since 2015, these pipes combine structural integrity with installation flexibility.

With ISO-certified quality control across our 5,000-10,000㎡ facility, we ensure consistent dimensional accuracy and material properties that meet international standards. These pipes eliminate weak points inherent in welded alternatives, providing superior pressure containment for critical infrastructure projects.

Core Technical Advantages:

• Seamless construction prevents leakage and corrosion at joints

• Rectangular profile optimizes space utilization in conduit bundles

• High strength-to-weight ratio reduces structural load

• Uniform wall thickness (±0.2mm tolerance) ensures consistent flow

• Customizable surface treatments for corrosion resistance

Standard Specifications:

Installation benefits include simplified alignment due to precise right-angle corners and compatibility with standard fitting systems. The smooth interior surface minimizes friction loss in fluid transport applications while the flat external surfaces facilitate secure mounting.

Our rectangular pipes undergo rigorous testing including hydrostatic pressure examination, ultrasonic flaw detection, and dimensional verification. Material traceability is maintained throughout production with heat number tracking.

Frequently Asked Questions:

Q: What makes seamless pipes superior to welded alternatives?
A: Seamless construction eliminates weld seams that can become failure points under cyclic stress, providing homogeneous material integrity throughout the pipe length.

Q: Can these pipes be used for underground installations?
A: Yes, when specified with appropriate corrosion protection (galvanization or epoxy coating). Soil resistivity testing is recommended for optimal coating selection.

Q: What certifications support your quality claims?
A: Our manufacturing processes are certified to ISO9004 (quality management) and ISO14000 (environmental management) standards, with material test reports available.

Q: Do you offer custom sizes outside standard dimensions?
A: Yes, we provide custom tooling for specialized cross-sections and wall thicknesses. Minimum order quantities apply for custom specifications.

Q: How do rectangular pipes compare to round pipes in structural applications?
A: Rectangular profiles offer superior resistance to bending in two axes and provide flat mounting surfaces, making them ideal for structural framing and conduit organization.

Q: What packaging options are available?
A: Standard packaging includes bundled units with protective end caps and moisture barrier wrapping. Special export packaging can be arranged upon request.
