Bs1387 Steel Tube

 

 

Bs1387 Steel Tube are a type of steel pipe that has been hot-dipped in a zinc coating to protect it from corrosion. This galvanization method ensures a longer lifespan for the pipes, making them suitable for various applications such as water supply, gas transportation, and construction projects. These pipes are also highly durable due to their electric resistance welding process. They comply with British Standards Institution specifications and are widely used in many industries worldwide.

BS1387钢管
Advantages of Bs1387 Steel Tube

High-quality material: BS1387 steel tubes are made from high-quality steel, which provides them with excellent strength and durability. This ensures that the tubes can withstand the high pressure and flow of fluids without breaking or leaking.

 

Wide range of sizes: BS1387 steel tubes come in a variety of sizes. This means that they can be used for a range of different applications, from small domestic plumbing systems to large industrial pipelines.

 

Easy installation: BS1387 steel tubes are easy to install, thanks to their simple design and easy-to-follow instructions. This means that they can be installed quickly and efficiently, reducing the need for skilled labor and saving time and money.

 

Low maintenance: Due to their high-quality construction, BS1387 steel tubes require minimal maintenance. They are resistant to abrasion and corrosion, which further reduces the need for repairs or replacements.

 

Versatility: BS1387 steel tubes are versatile and can be used for a range of different applications. They are suitable for transporting both hot and cold fluids, making them ideal for use in any climate.

 

Types of Bs1387 Steel Tube
 

Seamless BS1387 Galvanized Pipes

Manufactured without any welded joints, seamless pipes offer superior strength and integrity under pressure.

Welded BS1387 Galvanized Pipes

Formed by rolling steel sheets and welding the seam, these pipes are cost-effective and widely used in general applications.

Round Galvanized Steel Pipes

The most common shape, round pipes offer optimal flow efficiency and structural strength.

Square & Rectangular Galvanized Pipes

These profiled pipes offer enhanced rigidity and aesthetic appeal in structural and architectural applications.

Low-Pressure BS1387 Pipes

Designed for systems with minimal internal pressure, such as domestic water lines and gas distribution.

High-Pressure BS1387 Pipes

Engineered with thicker walls and tighter tolerances to withstand demanding industrial conditions.

 

Application of Bs1387 Steel Tube

Water Distribution Systems

Durability in Plumbing Infrastructure
BS1387 galvanized steel pipes have long been a staple in both residential and commercial water supply systems. Their resistance to internal and external corrosion makes them ideal for transporting potable water over extended periods.

Construction and Structural Supports

Reliable Framework Components
In construction, BS1387 pipes serve as essential structural elements in framing, support columns, and load-bearing assemblies. Their high tensile strength and ability to withstand dynamic loads make them suitable for both temporary and permanent installations.

Automotive Industry

Exhaust and Chassis Systems
Within the automotive sector, galvanized steel pipes are extensively used in exhaust systems, roll cages, and chassis components. The pipes' ability to resist high temperatures and corrosive exhaust gases—such as sulfur dioxide and moisture—ensures prolonged service life and reduced maintenance costs.

Agricultural Applications

Fencing, Gates, and Equipment Frameworks
Farmers and agribusinesses rely on galvanized steel pipes to build durable fencing, livestock enclosures, gates, and support structures for greenhouses and irrigation systems.

Scaffolding Systems

Safety and Stability in Elevated Work
One of the most critical applications of BS1387 pipes is in scaffolding for construction and maintenance projects. These pipes form the uprights, ledgers, and braces of modular scaffolds that support workers and materials at height.

Industrial Applications

Conveyance of Gases, Chemicals, and Steam
BS1387 pipes are widely used in industrial plants for low-pressure fluid and gas transmission. They are commonly found in pneumatic systems, compressed air lines, and steam distribution networks.

Outdoor Railings and Support Fixtures

Aesthetic and Functional Safety Solutions
Galvanized steel pipes are increasingly used in architectural applications such as handrails, guardrails, and support hangers for outdoor walkways, parks, and commercial buildings. Their sleek, metallic finish provides a modern industrial look while offering robust protection against weathering.

 

Standard calibration of TBs1387 Steel Tube

 

BS1387钢管
  • Dimensions and Tolerances

    Specifies nominal bore sizes, wall thicknesses, and outer diameters for both light and medium-grade pipes.

  • Material Quality

    Requires the use of weldable carbon steel with controlled chemical composition and mechanical properties.

  • Structural Integrity

    Mandates that welded seams must pass hydrostatic testing and be free from defects to ensure leak-proof performance.

  • Galvanization Requirements

    Defines minimum zinc coating thickness—typically ranging from 40 to 80 microns depending on pipe size and grade—to ensure effective corrosion protection.

 

Custom
 
 
 

Custom Dimensions

Non-standard lengths (e.g., 6m, 8m, or cut-to-size), special diameters, or unique wall thicknesses.

 
 

Enhanced Coatings

Thicker zinc layers beyond standard specifications, duplex coatings (zinc + paint), or additional sealants for extreme conditions.

 
 

Special Finishes

Powder-coated exteriors, color coding, or anti-fingerprint treatments for aesthetic or identification purposes.

 
 

Additional Testing

Optional non-destructive testing (NDT), chemical analysis reports, or third-party certification for quality assurance.

 

 

Maintenance and Longevity Tips

 

Regular Inspection

Check for signs of coating damage, rust at cut ends, or thread wear. Reapply protective sealants if necessary.

01

Proper Cutting and Threading

After cutting, treat exposed steel edges with zinc-rich paint to prevent localized corrosion.

02

Avoid Galvanic Corrosion

Do not directly connect galvanized steel to dissimilar metals like copper without dielectric unions.

03

Use Compatible Sealants

Apply PTFE tape or pipe dope suitable for threaded steel joints to ensure watertight seals.

04

Monitor Water Quality

In hard water areas, periodic flushing helps reduce mineral buildup inside pipes.
