High-Pressure Galvanized Pipe Fittings | Industrial Fluid Transport

Product Overview

High-pressure galvanized pipe fittings are engineered for demanding industrial fluid transport systems, offering superior corrosion resistance and structural integrity. These fittings are essential for applications in oil & gas, chemical processing, water supply, and power generation. The hot-dip galvanizing process ensures a robust zinc coating, extending service life even in harsh environments.

Technical Specifications

Key Features

1. Tensile & Bend Strength

Tensile strength (400–550 MPa) ensures resistance to internal pressure and mechanical stress, critical for high-pressure systems. Bend strength (300–450 MPa) prevents deformation under lateral loads, maintaining pipeline alignment.

2. Identification & Marking

Fittings are laser-etched with ASTM standards (e.g., A53, A123), size, pressure rating, and batch number for traceability.

3. Weight Calculation

Weight (kg/m) = (OD² – (OD – 2×WT)²) × 0.02466
Example: For a 2" (60.3mm OD) pipe with 3.5mm wall thickness:
(60.3² – 53.3²) × 0.02466 ≈ 4.89 kg/m.

4. Why Stainless Steel Can Rust

While stainless steel resists corrosion, chloride exposure (e.g., seawater), mechanical damage, or high-temperature oxidation can compromise its passive layer, leading to localized rust.

Maintenance & Application Tips

Galvanized Steel Pipe Repair

For minor corrosion, clean the affected area with a wire brush, apply zinc-rich paint or cold galvanizing spray, and inspect annually. Severe damage may require section replacement using rubber mechanical couplings or welding.

Galvanized Steel Water Pipes

Ideal for potable water systems due to zinc’s antimicrobial properties. Ensure joints are sealed with PTFE tape to prevent leaks.

How Do You Cut Galvanized Pipe

Use a reciprocating saw with a metal-cutting blade or angle grinder. Always deburr edges and apply anti-corrosion primer after cutting.
