Galvanized Steel Pipe 33.7mm

33.7mm Outer Diameter (OD) Hot-Dip Galvanized Steel Pipe is a precision-engineered conduit solution designed for superior corrosion resistance and structural integrity. Corresponding to the standard 1-inch nominal pipe size (NPS) and often Schedule 40, this pipe is manufactured under strict quality controls to meet international standards like ASTM A53. It is the ideal choice for plumbing, fencing, scaffolding, and industrial applications where reliability and longevity are critical. The hot-dip galvanized coating ensures a maintenance-free service life even in the most demanding environments.

Description: The primary advantage. The zinc coating acts as a sacrificial anode, meaning it will corrode before the underlying steel, even if the coating is scratched.

Benefit: Significantly extends the service life of the pipe, especially in environments prone to moisture and weathering. It can last 25-50 years or more depending on the environment.

High Strength and Durability:

Description: The steel core provides high tensile strength, making it capable of withstanding high physical impact, pressure, and heavy loads.

Benefit: Ideal for structural applications (e.g., scaffolding, handrails, frames) and underground burial where mechanical damage is a concern.

Long Service Life with Low Maintenance:

Description: Due to its corrosion resistance, it requires minimal upkeep over its long lifespan compared to unprotected steel.

Benefit: Reduces long-term costs associated with painting, repairs, and replacements.

Cost-Effectiveness (Initial Cost):

Description: While more expensive than black steel pipe initially, it is generally more affordable than many alternative corrosion-resistant materials like stainless steel, copper, or specialized alloys.

Benefit: Provides a good balance of performance and initial investment for many standard applications.

Versatility in Application:

Description: Can be used for a wide range of purposes, from transporting water to providing structural support.

Benefit: A reliable solution for plumbing, fencing, agricultural irrigation, electrical conduit, and construction projects.

Abrasion Resistance:

Description: The zinc coating is metallurgically bonded to the steel, making it tough and resistant to damage during handling, installation, and service.

Plumbing & HVAC: Potable water supply lines, waste lines, compressed air systems, and heating, ventilation, and air conditioning (HVAC) ducts.

Fencing & Handrails: As a top rail for chain-link fences, framework for gates, and structural balustrades or handrails for stairs and balconies.

Scaffolding & Construction: For light to medium-duty scaffolding frames, construction support props, and temporary structural frameworks.

Industrial & Agricultural: Conveyance of low-pressure gases, agricultural irrigation systems, protective conduits for electrical wiring, and machinery parts.

DIY & General Use: Outdoor furniture frames, greenhouse structures, DIY projects, and sports equipment.

Conclusion:

Galvanized steel pipe is an excellent choice for applications requiring a strong, durable, and corrosion-resistant material where its limitations are not a critical factor. It is ideal for:

Structural supports (handrails, frames, scaffolding)

Fencing and outdoor structures

Water supply lines (though being replaced by PEX in homes)

Electrical conduit (EMT)

Agricultural irrigation

Q: Is this 33.7mm pipe the same as a 1-inch pipe?

A: Yes, exactly. The Nominal Pipe Size (NPS) is "1 inch," but the actual outer diameter is standardized at 33.7mm. This is a critical distinction for ensuring compatibility with fittings.

Q: Is this pipe suitable for transporting drinking water?

A: Absolutely. When manufactured to ASTM A53 standards, our galvanized pipes are certified and safe for use in potable water systems.

Q: What is the difference between Schedule 40 and Schedule 80?

A: Schedule 80 has a thicker wall, resulting in a higher pressure rating but a smaller inner diameter (ID) and higher weight. Schedule 40 is the standard for general-purpose use.

Q: Can I get a sample order?

A: Yes, we encourage sample orders for quality verification. Please contact us to arrange a sample.
