Import Black Steel Pipes — Buy in Bulk from Supplier in India

Black steel pipes supplied by Maskot International are manufactured from carbon steel, with outer diameters ranging from 21.3mm to 610mm and wall thicknesses including SCH 40 and SCH 80. The pipes are produced without surface coatings, retaining the natural iron oxide finish from the hot rolling process. Lengths are supplied in 6-meter and 12-meter segments, with plain or beveled ends as standard. These pipes are designed for low-pressure fluid conveyance and structural applications.

The material is consistent with ASTM A53 Grade B and IS 1239 standards, with a typical carbon content of 0.25% and manganese content near 0.90%. The absence of a protective coating means the pipe relies on environmental conditions for corrosion resistance. In humid or coastal climates, additional protective measures such as painting or wrapping are recommended. The pipe is not intended for high-pressure or high-temperature service beyond standard industrial limits.

Contractors in construction, plumbing, and light industrial sectors in South Asia and East Africa commonly source these pipes for water lines, scaffolding, and non-critical gas distribution. Shipments are packed in steel strapping bundles and loaded in 20-foot containers. MOQ is not specified but is typically one container load. Buyers must confirm the applicable standard (ASTM or IS), end preparation, and inspection documentation before placing orders.
