Versatile Applications for Reliable Performance

These black structural pipes are ideal for use in construction, infrastructure, industrial settings, and general structural projects. Their high tensile and yield strengths ensure safety and structural integrity. With flexible connection options such as butt weld or threaded ends, they can be customized to suit various project needs.

Certified Quality and Robust Testing

Manufactured in accordance with ASTM A500 and IS 1239 standards, every pipe undergoes rigorous hydrostatic and non-destructive testing. This process guarantees pipes meet strict quality tolerances and performance requirements, offering dependable service life in demanding environments.

Customizable Packing and Sizing Solutions

Pipes are provided in lengths ranging from 6 to 12 meters, with packing options including loose bundled or as per customer specifications. Outer diameters and thicknesses can be selected to match the technical requirements of your specific project, ensuring optimal fit and performance.

FAQs of Black Structural Pipes:

Q: How are black structural pipes manufactured and tested for quality?

A: Black structural pipes are produced through the Electric Resistance Welded (ERW) process using mild steel. Stringent quality control is maintained through both hydrostatic and non-destructive testing to ensure reliability and structural integrity.

Q: What are the typical applications of these pipes in construction or industry?

A: These pipes are widely used in structural frameworks, industrial systems, construction scaffolding, and various infrastructure projects due to their strength, rigidity, and moderate corrosion resistance.

Q: What grade and standards do these pipes adhere to?

A: Black structural pipes meet ASTM A500, IS 1239, and material grades such as IS 2062 and IS 1239 Grade, satisfying international and Indian structural standards.

Q: When should I choose plain ends versus bevelled ends for my project?

A: Plain ends are ideal for applications requiring threading or simple welding, while bevelled ends are recommended for butt weld connections in structural installations, enhancing weld quality.

Q: Where can I source these pipes and fittings?

A: These pipes are available from authorized exporters, manufacturers, and suppliers across India, with fittings provided upon request to suit specific project requirements.

Q: What benefit does the black bituminous coating provide?

A: This coating offers moderate corrosion resistance, extending the service life of the pipes in environments where exposure to moisture or chemicals could otherwise lead to deterioration.

Q: How is the pipes size, weight, and length determined?

A: Pipe dimensionsthickness (28 mm), diameter (21355 mm), and length (612 m)can be selected based on your project specifications. Weight will vary according to the chosen size and length.
