What is 90 Degree Two Socket Tee Structural Pipe Fitting

Introduction

The 90 Degree Two Socket Tee is engineered to provide two sockets that are perpendicular to a vertical pipe, with both sockets also perpendicular to each other. Originally designed for upright supports, it securely connects two middle rails at right angles. This fitting enhances structural stability and is widely used in safety rails, fences, and custom frameworks.

Structure

This fitting builds on the design of a single socket tee by adding a second perpendicular socket. Each socket and the sleeve are equipped with hexagon set screws for firm fastening. The simple yet effective structure ensures pipes are securely connected, offering durability and ease of assembly in various applications.

How it Works

The 90 Degree Two Socket Tee works by clamping two horizontal pipes at right angles to a vertical upright. Once inserted, the pipes are secured by tightening the internal hex bolts on each socket. This creates a strong, stable connection without welding, making installation simple, reusable, and adjustable for various frameworks.

Advantages

This fitting provides a highly versatile connection for right-angled pipe assemblies. It ensures strong stability and reduces installation complexity by eliminating the need for welding. With multiple surface treatment options, it offers enhanced corrosion resistance and longer service life. Its flexibility makes it suitable for industrial, commercial, and DIY applications.

Application

In Guardrail and Handrail Systems:

The 90 Degree Two Socket Tee is commonly used to secure middle rails at right angles to uprights, ensuring both safety and stability.

In Fence Systems:

Installed at upright tops, it helps divide and reinforce different areas effectively.

In DIY Structures:

Ideal for projects that require additional perpendicular connections, such as square or rectangular frameworks. It allows two horizontal pipes to intersect at right angles, perpendicular to a vertical pipe, creating a strong cube-like frame. This is widely applied in building outdoor play equipment, greenhouse frames, storage racks, workbenches, and indoor furniture.

General Use:

Its adaptability and reusability make it perfect for temporary or permanent structures where strong, corrosion-resistant, and visually clean connections are required.

Materials

The 90 Degree Two Socket Tee can be manufactured from cast iron, stainless steel, or aluminum to suit different applications.

Cast Iron

Available in malleable iron and ductile iron, cast iron fittings offer excellent strength and cost-effectiveness. They are widely used in industrial and commercial frameworks due to their durability and ability to withstand heavy loads and long-term usage.

Stainless Steel

Stainless steel versions provide superior corrosion resistance, making them ideal for outdoor or marine environments. With a clean, polished finish, they are often chosen for structures requiring a modern appearance while ensuring reliable mechanical performance and long service life.

Aluminum

Aluminum fittings are lightweight yet durable, suitable for applications where reducing structure weight is important. They offer excellent corrosion resistance and easy handling, making them ideal for DIY projects, furniture frameworks, and other installations that require flexibility and convenience.

Surface Treatment and Suitable for Situation

Different surface treatments ensure durability, corrosion resistance, and suitability for various usage environments, from indoor settings to outdoor exposure.

Hot-dip Galvanizing

Hot-dip galvanizing provides a thick, durable zinc coating that offers long-lasting protection against corrosion. It is especially effective in outdoor and industrial environments where fittings are exposed to moisture, chemicals, or extreme conditions. This treatment ensures the fittings maintain strength and stability over time, even with heavy-duty use.

Double-Coating Galvanizing

This process combines hot-dip galvanizing with electro-galvanizing, resulting in an even stronger protective layer. It offers superior resistance to wear, scratches, and environmental damage. Double-coated fittings are especially suitable for environments with frequent physical contact, abrasive conditions, or where extended service life is required.

Powder Coating

Powder coating adds a decorative and protective finish in customizable colors. The coating provides excellent resistance against corrosion, UV rays, and abrasion, while improving the visual appeal of the fittings. It is ideal for architectural, indoor, and outdoor structures where appearance and durability are equally important.

Need to Pay Attention When Choosing the Right 90 Degree Two Socket Tee

Confirm whether the size of the 90 Degree Two Socket Tee meets the requirements of your system.

Ensure the surface treatment matches the environmental conditions of usage.

Need to Pay Attention When Choosing A Suitable Supplier
