Understanding BPI Steel Pipe Products: SIO, BOS, BRATA SENA and XL

July 14, 2025
Hello Pipe Enthusiasts!
 
Following our previous article on Understanding National and International Standards for Welded Steel Pipes: SNI, ASTM, API, JIS, AWWA, DNV, and UL, in this edition of #BPIPipeInsights, we will take a closer look at the steel pipe product line from Bakrie Pipe Industries (BPI) engineered to meet the specifications of those very standards.
 
In construction, manufacturing, and public utilities, selecting a steel pipe is not only about size and price, but also about production quality, dimensional accuracy, and reliable technical support. This article explores five featured brands from BPI: SIO, BOS, BRATA SENA and XL, along with their specifications and industry usage.
 
# SIO – Steel Pipe for General Purpose Specification

Specification

Details

Shape

Round Pipe

OD (mm / inch)

21,3 mm – 406,4 mm (½" – 16")

Thickness (mm)

2,0 – 6,35 mm

Length

6 meters

📎 SIO represents the thickest wall pipe product in the BPI 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 – Steel Pipe for General Purpose Specification

Specification

Details

Shape

Round Pipe

OD (mm / inch)

21.3 – 114.1 mm (½”  – 4")

Thickness (mm)

1,8 – 2,3 mm

Length

6 meters

📎 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 – RHS (Rectangular Hollow Section)

Shape

Size RHS (mm × mm)

Thickness (mm)

Length

RHS

40×20 – 140×60

1,8 – 4,0

6 meter


# SENA – SHS (Square Hollow Section)

Shape

Size SHS (mm × mm)

Thickness (mm)

Length

SHS

20×20 – 100×100

1,8 – 6,0

6 meter

📎 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 & SHS / RHS 

Tipe

Size OD / Side (mm / inch)

Thickness (mm)

Length

Round Pipe

21,3 – 60,3 mm (½" – 2")

1,3 – 1,5 

6 meters

📎 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.
 

Tipe

Size OD / Side (mm / inch)

Thickness (mm)

Length

SHS/RHS

20×20 – 40×40 mm

1,3 – 1,5

6 meters

📎 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
BPI’s five steel pipe products SIO, BOS, BRATA SENA and XL, have been developed to meet real-world market demands and technical requirements without compromising safety, quality, or 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, BPI continues to provide reliable solutions trusted by contractors, engineers, and industry professionals.
