Galvanized Malleable Iron Tees and Crosses Set

Galvanized Malleable Iron Tees and Crosses Set

Product Overview

The Galvanized Malleable Iron Tees and Crosses Set is a specialized collection of branching fittings designed for complex piping distribution networks. Manufactured from high-strength malleable iron (ASTM A197) and coated with a heavy layer of hot-dip galvanized zinc, this set provides the essential components needed to split, combine, or distribute fluid flow in four directions. These fittings are engineered for durability and high-pressure performance, making them the ideal choice for water, gas, steam, and industrial piping systems where reliable branching connections are critical.

Key Features and Benefits

• Complex Flow Management: Provides the necessary geometry to create branch lines (Tees) or four-way intersections (Crosses) within a piping system.

• Superior Corrosion Resistance: The hot-dip galvanized coating offers robust protection against rust and oxidation, suitable for outdoor, underground, or wet environments.

• High Mechanical Strength: Malleable iron construction ensures high tensile strength and impact resistance, capable of withstanding heavy loads and pressure surges without cracking.

• Leak-Tight Connections: Precision-machined tapered threads (NPT/BSP) ensure a secure, seal-tight joint when assembled with pipe sealants.

• Versatility: Suitable for a wide range of applications including potable water, natural gas, steam, compressed air, and fire protection systems.

Set Components

This set focuses specifically on branching and intersection fittings, available in various configurations to suit different piping layouts:

1. Pipe Tees (Branching)

• Equal Tee: All three outlets are the same size (e.g., 1" x 1" x 1"). Used when the branch line is the same diameter as the main run.

• Reducing Tee: The branch outlet is smaller than the main run outlets (e.g., 1" x 1" x 3/4"). Used to feed smaller branch lines from a larger main.

2. Pipe Crosses (Intersections)

• Equal Cross: All four outlets are the same size. Used for four-way intersections in grid-like piping systems.

• Reducing Cross: One or more outlets are reduced in size to accommodate different pipe diameters within the same junction.

Applications

The Tees and Crosses Set is widely utilized in critical infrastructure and industrial systems:

• Plumbing & Water Supply: Creating branch lines for sinks, toilets, and showers from main distribution pipes.

• Natural Gas Distribution: Splitting gas lines for appliances (stoves, heaters, dryers) safely.

• Fire Sprinkler Systems: Connecting drop lines to main cross-mains in commercial and industrial buildings.

• HVAC Systems: Steam heating lines and condensate return loops.

• Industrial Process Piping: Distributing compressed air, oil, or process fluids to multiple machines.

• Structural Applications: Used in handrails and fencing for structural intersections.

Quality Assurance

We ensure that every fitting in the Tees and Crosses Set meets rigorous international standards for safety and performance. Our manufacturing process includes chemical analysis, mechanical testing (tensile and yield strength), and hydrostatic pressure testing. The galvanized coating is inspected for thickness and adhesion to ensure maximum corrosion protection. We provide full traceability and documentation, including Mill Test Certificates (MTC) and compliance statements for ASTM, ISO, and GB standards.
