Hello Pipe Enthusiasts!
Following our previous discussion on Understanding National and International Standards for Welded Steel Pipes: SNI, ASTM, API, JIS, AWWA, DNV, and UL, this edition of #SEAPIPipeInsights takes a closer look at the genuine steel pipe products from Bakrie Pipe Industries (BPI) now exclusively distributed by SEAPI.
In the realms of construction, manufacturing, and urban utilities, choosing the right steel pipe is about more than just size and price; it’s about production quality, dimensional accuracy, and technical support. This article explores five flagship brands: SIO, BOS, BRATA, SENA, and XL, outlining their specifications and intended applications.

📎 SIO represents the thickest wall pipe product in the SEAPI lineup. It is well suited for commercial and industrial facilities requiring pipes that withstand light to medium pressure, including main clean water lines for high-rise buildings, hydrant and fire protection systems (especially low-pressure supply to nozzles/valves), factory utility distribution (such as cold water, non-chemical process water, and backup pipelines), and casing for mechanical or cable protection, such as open conduit shielding in light mining or outdoor installations. Its extra thickness makes it ideal for locations that need enhanced installation safety, even if the wall does not have to meet minimum SNI standards for high-pressure systems.

📎 BOS is used in non-structural construction such as steel plating, suspended ceilings, partition frames, MEP works inside buildings (including electrical conduits, lightweight ducting, and ventilation systems), non-pressurized water lines (rainwater, domestic wastewater, treated groundwater), and as structural supports for light machinery in factories, workshops, or laboratories. BOS is a smart choice for projects with budget constraints that still demand dimensional consistency and dependable performance, especially in fabrication workshops.

📎 BRATA and SENA are well-suited for structural frames, heavy-duty construction, and modular designs. BRATA (RHS) is often used for building foundations, bridge pylons, infrastructure fencing, and steel panel supports in public utility projects. SENA (SHS) is more flexible for industrial and institutional sectors, from storage racks and canopy frames to lighting poles and medical furniture, such as hospital beds, IV stands, logistics trolleys, and wheelchairs. Both support precision fabrication and offer professional appearance across project types.

📎 XL Round Pipe is ideal for low-pressure water distribution, light drainage systems, and indoor utility networks including split AC pipes and closed fan coil lines. Due to its thin wall (1.3 – 1.5 mm), it is preferred for light-duty applications and easy indoor installations.

📎 XL SHS/RHS small size variants are used for modular frames, lightweight logistics racks, machine casings, and ducting structures. Their compact and thin-walled profile makes them popular for manufacturing, metal furniture assembly, and practical construction work that still requires precise symmetry.
Conclusion
Five steel pipe products from our top brands namely SIO, BOS, BRATA SENA, and XL have introduced steel pipe products designed to meet market demands and technical requirements in the field, without neglecting aspects of safety, quality, and efficiency. Amidst a competitive landscape where some products offer low prices but lack guaranteed specifications, such as unbranded pipes with unclear material, dimensions, or manufacturing controls, SEAPI continues to provide reliable solutions trusted by contractors, engineers, and industry professionals.
