How To Connect A Non-Threaded Galvanized Pipe?

Jun 28, 2024 | Industry News, News

Connecting a non-threaded galvanized pipe can seem like a daunting task, but with the right knowledge and tools, it can be done efficiently and securely. Galvanized pipes are commonly used in plumbing systems due to their durability and resistance to corrosion. In this guide, we will explore various methods and fittings to connect non-threaded galvanized pipes, emphasizing the benefits of using high-quality products such as malleable iron pipe fittings, cast iron pipe fittings, and grooved pipe fittings Rubber Joint.

Understanding Galvanized Pipes and Fittings

Galvanized pipes are steel pipes that have been coated with a layer of zinc to prevent rust and corrosion. These pipes are widely used in water supply lines, outdoor applications, and some interior plumbing. While threaded connections are common, non-threaded galvanized pipes require alternative methods for secure connections.

Methods for Connecting Non-Threaded Galvanized Pipes

1. Compression Fittings

   – Compression Couplings: These are ideal for joining non-threaded galvanized pipes. A compression coupling consists of a rubber gasket and a metal sleeve that compresses around the pipe when tightened.

   – Insert Couplings: Often used for quick repairs, these couplings fit inside the pipe ends and are sealed with compression nuts.

2. Grooved Pipe Fittings

   – Rigid Coupling: Suitable for rigid, secure connections, rigid couplings have grooves that fit into the pipe ends. They are tightened with bolts, ensuring a leak-proof seal.

   – Flexible Coupling: Flexible couplings allow for slight movements and are excellent for systems that may experience vibrations or thermal expansion. They also use grooves and are secured with bolts.

   – Grooved Welded Outlet: For branching off from a main pipe, grooved welded outlets are welded onto the pipe and provide a grooved end for connections.

3. Flange Adaptor

   – Flange Adaptors: These adaptors convert the end of a non-threaded pipe to a flange connection. The adaptor is clamped onto the pipe end and then bolted to a corresponding flange, providing a strong and durable joint.

4. Rubber Joints

   – Flexible Rubber Joint Single Sphere: These joints provide flexibility and can absorb vibrations and movements. They are clamped onto the pipe ends with stainless steel bands.

   – Flexible Rubber Joint Twin Sphere: Similar to single sphere joints but provide even greater flexibility and movement absorption.

5. Welded Connections

   – Welded Outlet: Welding provides a permanent and secure connection. A welded outlet can be used to create a branch or change pipe direction. This method requires skilled welding to ensure a proper seal.

Selecting the Right Fittings

When choosing fittings for non-threaded galvanized pipes, consider the application and specific requirements of your plumbing system. High-quality fittings such as malleable iron pipe fittings, cast iron pipe fittings, and grooved pipe fittings offer durability and reliability. Here are some benefits of these fittings:

– Malleable Iron Pipe Fittings: Known for their strength and flexibility, these fittings can withstand high pressure and are less likely to crack under stress.

– Cast Iron Pipe Fittings: These are extremely durable and resistant to wear and corrosion, making them ideal for long-term applications.

– Grooved Pipe Fittings: These fittings provide easy installation and maintenance, especially useful in fire fighting fittings and large-scale plumbing systems.
