Threaded-End Galvanized Pipe Fittings | Seamless Installation Options

Product Overview

Threaded-end galvanized pipe fittings are engineered for durability and versatility in plumbing, irrigation, fire protection, and industrial systems. These fittings are hot-dip galvanized to ensure superior corrosion resistance and longevity, even in harsh environments. With precise threading adhering to BSPT, NPT, and ISO 7-1 standards, they guarantee leak-proof connections and compatibility with various piping systems.

Specifications

Key Features

1. Superior Corrosion Resistance: The hot-dip galvanized coating provides a robust barrier against rust and environmental degradation, making these fittings ideal for outdoor and high-moisture applications like agricultural irrigation and sewage treatment.
2. High Pressure Tolerance: Engineered to withstand pressures up to 9000psi (forged carbon steel variants), these fittings are suitable for hydraulic systems and industrial pipelines.
3. Diverse Compatibility: Seamlessly connect galvanized pipe to PVC or other materials using adapters, ensuring flexibility in hybrid piping systems.
4. Precision Threading: Threads are machined to strict standards to prevent leaks, even under thermal expansion or vibration.

Technical Explanations

Tensile & Bend Strength

• Tensile Strength:
  Malleable iron fittings exhibit a tensile strength of 350 MPa (EN-GJMB-350-10), while stainless steel (Grade 316L) offers 485–650 MPa. This ensures structural integrity under high-pressure conditions.
• Bend Strength:
  The ductility of galvanized coatings allows fittings to endure bending stresses without cracking. For example, malleable iron fittings can withstand a bend angle of 90°–180° without deformation.

Identification & Marking

Fittings are laser-etched or stamped with:

• Material Grade (e.g., ASTM A105, EN-GJMB-350-10).
• Size (NPS or metric).
• Pressure Rating (PN16, 2000psi, etc.).
• Certification Marks (UL, FM).

Weight Calculation

Weight is determined by material density and dimensions:

• Formula: $\text{Weight (kg)}=\text{Volume}\times \text{Density}$.
  Example: A 1" stainless steel elbow (Schedule 40) weighs approximately 0.45 kg based on ASTM A312 standards.

Stainless Steel Corrosion Causes

While stainless steel is highly corrosion-resistant, improper use can lead to rust:

1. Galvanic Corrosion: Occurs when stainless steel contacts galvanized steel pipe coupling or dissimilar metals in electrolytic environments (e.g., saltwater).
2. Chloride Exposure: High chloride concentrations (e.g., coastal areas) can penetrate passive oxide layers, causing pitting.
3. Mechanical Damage: Scratches or welding defects expose raw metal to oxidation.

Applications

• Fire Protection Systems: Used in sprinkler networks due to FM/UL certifications.
• Water Treatment: Resists galvanized steel pipe corrosion in chlorine-rich environments.
• HVAC & Plumbing: Compatible with galvanized pipe to PVC transitions in residential and commercial buildings.
• Industrial Pipelines: Handles aggressive fluids in chemical plants with stainless steel variants.
