Reliable Construction and Versatility

These black pipes are widely used for gas, water, and steam delivery in construction, plumbing, and industrial applications. Their cylindrical, weldable design and excellent elongation (minimum 15%) make them suitable for high-strength installation where both performance and safety are essential.

Superior Material and Finish

Manufactured from premium mild steel with a black varnished surface, these pipes offer outstanding rust resistance and longevity. Compliance with industry standards such as ASTM A53 and IS 1239 ensures consistent quality, while the black painted finish enhances corrosion resistance in harsh environments.

Flexible Sizing and Customization

Available in diameters ranging from 1/2 inch to 12 inches and lengths up to 12 meters, our pipes accommodate diverse project requirements. Customers can select from plain or threaded ends, and tight dimensional tolerance (0.5 mm) ensures precise fitment in various applications.

FAQs of Black Pipe:

Q: How are the black pipes packaged for shipment?

A: The pipes are bundled securely using steel strips to prevent damage during transit. Each pipe end is also protected with plastic caps to maintain product quality until delivery.

Q: What process is used to manufacture these black pipes?

A: These pipes are produced using the Electric Resistance Welded (ERW) method, which ensures strong, consistent seams and reliable structural integrity suitable for industrial and construction applications.

Q: Where can these black pipes be used effectively?

A: They are ideal for use in construction frameworks, plumbing installations, and industrial systems requiring the conveyance of water, air, oil, and gas, including gas, water, and steam pipelines.

Q: What are the benefits of choosing this black pipe for projects?

A: Key advantages include excellent weldability, high strength, rust resistance, precise manufacturing tolerances, and a corrosion-resistant finish, resulting in durable and reliable pipework for demanding applications.

Q: When is it necessary to use black pipes with a high-pressure rating?

A: Black pipes rated up to 25 bar are essential for systems where fluids are conveyed under significant pressure, such as in industrial process lines or building plumbing systems handling gas and steam.

Q: What sizes and thicknesses are available for order?

A: The pipes come in outer diameters from 1/2 inch to 12 inches, with wall thicknesses ranging from 2.5 mm to 10 mm. Lengths of up to 12 meters can be supplied to suit project-specific requirements.

Q: How do the pipes resist corrosion in harsh environments?

A: A black varnish surface treatment and black painted finish provide a robust layer of protection, making these pipes well-suited for environments where moisture or corrosive elements are present.
