Polyethylene or polypropylene BSP fittings are not recommended for compressed air applications, and are really only suitable for water. With our vast selection of fittings, you will find something to match your needs.

If you are looking for threaded pipe fittings and are still determining what would be ideal for your system, you can rest assured. We are here to aid you with your queries and doubts so that you can get the best results. We at Air Energy guarantee the quality and provide you with a competitive price for our products.

Galvanized Pipe Fittings

Galvanised fittings are not dipped into molten zinc and then any threads are cut afterwards otherwise the molten zinc will block up the threads. Other zinc coatings can be applied by electroplating and may be colloquially referred to as galvanised, but the coating, although protecting threaded areas, is much thinner than actual galvanising. all zinc coatings are applied to steel to protect it from rust and corrosion. Making threaded pipes and pipe fittings out of galvanised steel rather than black or bright steel is is highly recommended since it gives resistance to rust and corrosion.

Galvanized steel fittings are offered in conventional diameters ranging from 1/4″ to 4″.

Advantages Of Galvanised Steel Pipes

Galvanized steel gains popularity from its ability to withstand corrosion and cheap cost, however pressfit stainless systems have largely replaced galvanised steel for pipework due to the much faster installation time, increased internal diameter and much better appearance and performance. Galvanized pipe fittings can endure the effects of weather for 50 to 70 years, making them long-lasting.

Disadvantages of Galvanized Pipe Fittings

Regardless of the number of advantages, the drawbacks of galvanized pipes are also to be considered when using the system.

Prone to internal corrosion

Steel pipes have a zinc coating on their outsides to prevent corrosion. Still, if even a little portion of that coating is removed, the pipe will begin to rust wholly and within corrode.

Water or Food Contamination

If the pipe develops rust or corrosion, the metal will react with the water and release toxic compounds that will form plaque inside the pipe and contaminate the water supply. GI Pipes are not food-grade materials. Thus the water from their water supply cannot be used for potable reasons.

Frequently Asked Questions

Galv Threaded Rod Vs. Stainless Steel: Which Is Right For Your ...

Compare galv threaded rods with stainless steel options, discussing their respective advantages and disadvantages for various applications.

When it comes to selecting threaded rods for construction and industrial applications, the choice between galv threaded rods and stainless steel options can significantly impact performance, durability, and cost. Each material has its own set of characteristics that make it suitable for different situations. In this article, we will compare galv threaded rods and stainless steel threaded rods, discussing their respective advantages and disadvantages across various applications.

What are Galv Threaded Rods?

Galv threaded rods are steel rods that have been coated with a layer of zinc to protect them from corrosion. The galvanisation process involves immersing the steel in molten zinc, creating a barrier that prevents moisture and environmental factors from degrading the metal. This makes  threaded rods ideal for use in applications where they are exposed to the elements.

Key Features of Galv Threaded Rods

  1. Corrosion Resistance: The primary benefit of threaded rods is their resistance to rust and corrosion, which is crucial for outdoor and marine applications.
  2. Cost-Effective: Galvanised rods are generally more affordable than stainless steel options, making them a popular choice for budget-conscious projects.
  3. Versatile Applications: These rods can be used in a variety of settings, including construction, manufacturing, and automotive industries.

What are Stainless Steel Threaded Rods?

Stainless steel threaded rods are made from steel alloyed with chromium, nickel, and other elements, which give them exceptional corrosion resistance. Unlike threaded rods, stainless steel rods do not require additional coatings to maintain their durability.

Key Features of Stainless Steel Threaded Rods

  1. Superior Corrosion Resistance: Stainless steel rods excel in highly corrosive environments, such as chemical plants or coastal areas, where exposure to saltwater can quickly degrade other metals.
  2. High Strength and Durability: Stainless steel offers a higher tensile strength than galvanised rods, making them suitable for heavy-duty applications where strength is paramount.
  3. Aesthetic Appeal: Stainless steel has a polished, clean appearance, making it a preferred choice for visible applications in architecture and design.

Advantages of Galv Threaded Rods

1. Cost Efficiency

One of the most significant advantages of galv threaded rods is their affordability. They are less expensive than stainless steel options, making them an attractive choice for projects with tight budgets.

2. Good Corrosion Resistance

While not as durable as stainless steel in extreme conditions, threaded rods provide adequate protection against rust and corrosion for many outdoor applications. They are suitable for environments that are moderately wet but not exposed to harsh chemicals.

3. Ease of Availability

Galv threaded rods are widely available and can be found at most hardware and construction supply stores. Their commonality makes sourcing them for projects relatively easy.

4. Adequate Strength

For many applications, the strength of galv threaded rods is sufficient. They can handle moderate loads, making them a practical choice for a variety of construction and manufacturing projects.

Disadvantages of Galv Threaded Rods

1. Limited Durability in Harsh Environments

While galv threaded rods resist corrosion, they are not ideal for environments with high levels of moisture, chemicals, or extreme temperatures. In such conditions, the zinc coating may wear off, leading to rust.

2. Aesthetics

Galv threaded rods have a utilitarian appearance that may not be suitable for projects where aesthetics are a concern. Their appearance may not meet the standards required for visible architectural applications.

Advantages of Stainless Steel Threaded Rods

1. Exceptional Corrosion Resistance

Stainless steel threaded rods shine in corrosive environments. Their inherent properties provide protection against rust and degradation, making them perfect for marine applications, chemical processing plants, and food manufacturing.

2. High Strength

Stainless steel rods have a high tensile strength, making them suitable for heavy-duty applications. They are less likely to bend or break under high loads, which is critical in construction and industrial settings.

3. Low Maintenance

Due to their durability, stainless steel rods require minimal maintenance. They do not need to be replaced as frequently as galv threaded rods, which can save costs in the long run.

4. Aesthetic Appeal

The polished finish of stainless steel threaded rods gives them an attractive appearance, making them suitable for visible applications in architectural and design contexts.

Disadvantages of Stainless Steel Threaded Rods

1. Higher Cost

One of the main drawbacks of stainless steel threaded rods is their cost. They are generally more expensive than galv threaded rods, which can significantly impact project budgets, especially for large-scale applications.

2. Limited Availability

While stainless steel options are becoming more common, they may not be as readily available as galv threaded rods at local hardware stores, potentially leading to longer lead times for sourcing materials.
