Manufacturer of Steel Pipes in Gujarat: Steel Pipe Thickness & Grades Buyer Guide
Steel pipes are the backbone of infrastructure and industrial progress. From high-rise buildings and pre-engineered warehouses to irrigation systems and oil pipelines, their role is indispensable. Whether for structural support or fluid transmission, the quality, grade, and thickness of steel pipes determine a project’s long-term success, safety, and cost efficiency.
Yet, many buyers overlook a critical factor when selecting steel pipes—wall thickness and material grade. Focusing only on diameter or price often results in performance failures, corrosion issues, or inflated project costs.
For engineers, EPC contractors, procurement managers, and fabricators, understanding steel pipe thickness and grade is essential before placing an order. This detailed guide is brought to you by Asian Group of Companies, a leading manufacturer of steel pipes in Gujarat, to help buyers make informed, cost-effective, and technically sound purchasing decisions. We’ll explore grades, wall thickness, application-specific selection, and more—ensuring you choose the right steel pipe for the job.
Understanding Steel Pipe Thickness
Steel pipe thickness refers to the wall thickness of the pipe, generally measured in millimeters. It significantly influences a pipe’s mechanical strength, pressure-handling capacity, and service life. For example, two pipes with identical diameters but different wall thicknesses may perform very differently under load.
A thicker pipe generally supports higher pressure and structural loads, while thinner pipes are suitable for light-duty applications. Inaccurate selection often leads to over-engineering or failures, increasing project risks or costs.
Why Thickness Matters Before Ordering
Using steel pipes with incorrect thickness can lead to:
- Structural instability
- Premature cracking or deformation
- Increased fabrication complexity and costs
- Higher maintenance due to corrosion or damage
On the other hand, over-specifying thickness adds unnecessary weight and cost without improving performance. Precision in thickness selection ensures an ideal balance between strength, economy, and long-term reliability.
Common Thickness Standards
Recognized standards help ensure consistency across pipe manufacturing and procurement. Major standards include:
- IS (Indian Standards)
- ASTM (American Society for Testing and Materials)
- API (American Petroleum Institute)
- EN (European Standards)
Thickness can be expressed in:
- Millimeters (mm)
- Schedule Numbers (e.g., SCH 40, SCH 80)
- Gauge Systems
Buyers should confirm the relevant standard in their technical specifications.
Steel Pipe Grades Explained
Steel pipe grades reflect the material’s chemical and mechanical properties. These include:
- Tensile strength
- Yield strength
- Hardness
- Weldability
Choosing the wrong grade can result in:
- Brittleness under stress
- Poor weld joints
- Reduced service life
Correct grade selection should align with environmental conditions, structural requirements, and compliance standards.

Environmental and Cost Impact of Thickness
Over-specifying thickness:
- Increases steel consumption
- Raises carbon emissions
- Elevates project cost
Right-sizing thickness promotes sustainability and project economy.
Common Mistakes to Avoid
- Ignoring application-based thickness
- Not specifying tolerance limits
- Choosing unverified suppliers
- Overlooking coating needs for outdoor use
FAQs
Q: What thickness is best for structural projects?
A: Depends on load and design. Square/rectangular MS Pipes are typically used.
Q: Is thicker always better?
A: No, over-thickness adds cost without always improving safety.
Q: How do I ensure accurate thickness?
A: Work with certified manufacturers that control tolerances.
Q: Which grade suits outdoor use?
A: GI or GP pipes with zinc coating.
Q: Can one pipe type fit all applications?
A: No, each application requires specific grade and shape combinations.
