Understanding Pipe Fittings and Pipe & Tube

by mandeep deol on October 07, 2021

The forms of pipe fittings that can be used to connect pipes for handrails and other architectural elements, where providing a leak-proof connection is not a requirement. Pipe fittings may be welded or threaded, mechanically joined, or chemically adhered, to name the most common mechanisms, depending on the material of the pipe.


Types of pipe fittings: An assortment of pipe fittings.

Material of Pipe Fittings: Stainless Steel

It’s Strong

If you need a material that can withstand the elements – be it wind, rain, sun or snow – then you need steel. Using steel also means you have no worries when it comes to mold, mildew and fungi and it is more resistant to fire and doesn’t warp, distort, buckle or splinter. This durability makes it cost effective too, as it’ll stand the test of time.

It’s Ductile

Steel might be strong, but that doesn’t mean it isn’t flexible. The ductility of this metal means that it can be rolled or cut up into any shape or size that you require.

It’s Less Expensive and More Efficient

Choosing steel for your next project will help reduce its overall expense and enhance its value. For many projects, the cost of steel is lower than that of competing systems.

Clamps are Environmentally Friendly

Businesses across the globe are becoming more eco-friendly. This is reflected in the construction industry and the practices that are used. Steel is made from recycled materials and it can be recycled when you’re finished with it too – making it an ideal choice for people keen to showcase their green credentials while engaged in construction projects. With 80 million tons of steel recycled every year, it’s said to be the world’s most recycled product.


Pipe vs. Tube

For your convenience we have put our full range of Pipe in one chapter. Choose from Steel, Galvanized Steel, Stainless Steel or Aluminum.

What is the difference between Pipe and Tube? That is a question that is being asked a lot and might not be obvious at first glance since they are both round and hollow.

Pipe is mainly used for pressurized applications. It is sized Nominal in Imperial Fractions and is standardized throughout the world. As an example, a 1” SCH 40 pipe has an outside diameter (OD) of 1.315” and an inside diameter (ID) of 1.049” which is fairly close to 1” which is why it is designated as a 1 inch pipe.

Tube on the other hand is sized on the OD with the wall thickness and is used for structural purposes. Dimensions are either in inches or millimeters.

Tube in most cases will also have a welded seam on the inside, unless it is specified as a DOM (drawn over mandrel) or seamless tube.

If wall thickness and strength are not the main objective but pricing is, then there are lots of tubes available that will match the outside diameter of many pipe sizes.

Type of Tube: Steel Tube and Flow Coat Tube

Steel Tube


The strength of steel tube makes it the good option for most projects. its strength enables it to withstand vibrations, shock and high pressure. Unlike other metals, steel will bend rather than break under extreme conditions.

Easy Installation

Custom steel pipes can be cut to any length. They can also be easily modified on-site, making them easy to install. Any maintenance or modifications that are needed after installation can be done quickly and easily because steel is a very easy metal to work with in that manner.

Greater Capacity

Steel tubes come in many different sizes and wall thickness which make steel tube more affordable and adaptable for specific needs or budgets.

Steel Tubes are Environmentally-Friendly

Using steel is a great way to look out for the local environment. Approximately 70% of all the steel used in North America gets recycled each and every year. Steel can be recycled frequently without losing its quality and strength.

Flow Coat Tube


Flo-Coat galvanized tubing is the product of choice where strength & superior corrosion protection is required. Flo-Coat tubing is fabricator friendly and in most cases is suitable for bending, flattening, welding, drilling and painting. Flo-Coat is also environmentally friendly boasting 99.9% pure zinc coating. Flo-Coat is already widely used in playground, agri, greenhouse, shelters and many other related applications. The patented rolling process used to manufacture Flo-coat products also fosters high strength properties over conventional or fence related products - up to 50,000 ksi yield and 55,000 ksi tensile strength. Flo-coat is a tube that consistently performs, thus enabling cost & service efficiencies over hot dip galvanized applications.


Unlike other metals that rust or corrode easily, flow coat tubes are rust-proof and are resistant to other chemical reactions that can cause corrosion. This helps them to be more maintenance-free than other types of tubes, lasting for many years beyond installation.

Flow Coat Product Features

  • Attractive, smooth, shiny surface appearance.
  • Resistant to oxidization or “grey down” with age. Resists “white surface rust”
  • Superior strength & corrosion resistance properties.
  • Zinc - rich interior paint to protect inner tube.
  • Clear Organic Coating acts as a primer for liquid/spray paints or powder coats

Type of Pipe: Aluminum Pipe and Galvanized Pipe

Aluminum Pipe


Aluminum pipe is less susceptible to corrosion and less resistant to airflow making them overall more energy efficient. Uneven surfaces and build-ups can cause obstructions with many other leading materials causing a great deal of resistance. Having a pipe with a smoother surface and a material resistant to corrosion makes your overall air system run much more efficient.

Where are Aluminum Pipes Used?

Aluminum pipe is mostly used for various industrial or building uses, but the use of aluminum pipe and the aluminum tube is also easily embraced by homeowners and auto manufacturers and has been modified for common household use.

In the demand to interior furnishings aluminum pipes are also used. Things are generally constructed of wrought iron from canopy beds and bedside tables. Aluminum tubes are a lightweight choice which gives a futuristic feel to the room. To threaded forms of tubing a variety of fasteners are given. Aluminum Pipe is a machined part widely used for all types of industrial projects where lightweight and corrosion resistance are the primary concern. Printed in both 6061-T6 and 6063-T6, 6063 has a smoother texture than 6061 and is more bendable.

Galvanized Pipe:


By providing an extra layer, rust must pass through if rust is contaminated. The iron in steel reacts with oxygen and water and easily causes rust, which leads to deterioration of the object. With a zinc coating, these elements are less likely to cause this reaction.

Lower the Price

The galvanizing process is usually less costly than other popular pipe protection methods. This is because other methods usually require a lot of labor, while galvanizing requires less physical labor. At the same time, the service life of galvanized steel pipe is also very long. It can be used for more than 50 years in many rural areas and for more than 25 years in severely exposed urban and coastal environments. As a result, maintenance costs are lower.

Easy to Check

The inspection process of galvanized pipe is simple and clear. Galvanized coatings can be visually examined, and their thickness can be tested using a simple nondestructive testing method.

Where are G Alvanized Pipes Used?

Galvanized pipe is used in outdoor and indoor applications due to its anti rusting components. The zinc coating slows the process of corrosion and can make the pipe last for decades (in the right environment). This makes it ideal for marine applications and for transporting hot and cold water alike.
