What You Need To Know About BS1387 Galvanized Steel Pipe

April 29, 2021

BS1387 Galvanized Steel Pipe

A BS1387 galvanized steel pipe is a steel pipe coated with a layer of zinc coating. The protective zinc layer makes the steel pipe resistant to rust and corrosion. This type of steel piping was invented slightly before the 1960s, and it was then a perfect alternative to the water supply lead pipelines. A galvanized steel pipe is like seamless welded pipes and carbon steel tubes or pipes. It meets the standards ASME B3610m, API 5L, and ASTM A53. Do you want to know more about this variant of steel piping? If yes, then read this article till the end.

About BS1387 Galvanized Steel Pipe

As we said earlier, it is a type of steel piping with enhanced rust and corrosion resistance. Therefore, you can use this piping solution for applications where your primary objective is to find a steel piping solution with improved rust and corrosion resistive properties. A BS1387 galvanized steel pipe is best for fluid, gas, construction, structure, and steam conveyance.

Various welding procedures are used for different types of applications. Therefore, there are different types of galvanized pipes available, such as ERW pipes, SSAW pipes, and LSAW pipes. An ERW steel pipe is made using top-quality, control-rolled, continuous-cast, fine-grain, galvanized, or low-carbon steel. Top-of-the-line steel grade ensures better corrosion resistance, improved strength, better tolerance level, and enhanced deformability.

Modern-day machines, such as pipe mills, slitting lines, finishing machines, high-pressure hydro-testing machines, threading machines, and galvanizing units ensure accuracy in welding steel pipes.

The following table shows the chemical composition and mechanical properties of a galvanized steel pipe at room temperature:

Ladle - Chemical Composition Mechanical Properties - At Room Temperature

We will discuss the tolerance, ends, bend test, flattening test, leak tightening test, and other properties of a galvanized pipe in upcoming articles. Now, let’s go through the uses and benefits of a galvanized pipe.

Galvanized Steel Pipe Types and Uses

Galvanized steel pipe comes in two kinds; hot dipped, and cold galvanized pipes. Cold galvanized pipes are also known as electric galvanized pipes. There are numerous uses of these pipes in both commercial and residential buildings. Generally, a BS1387 galvanized steel pipe is the most suitable type of steel pipe. It is used to transfer gas, water, oil, and other liquid substances.

Galvanized steel pipes are commonly used in:

  • Construction
  • Plumbing
  • Ballard
  • Cold and hot liquid transportation
  • Fencing
  • Marine environments
  • Exposed environments
  • Railings

Galvanized steel pipe is a solid steel pipe that comes in several shapes. It is the most popular steel pipe nowadays.

Benefits of Galvanized Steel Pipes

There are so many benefits for which a galvanized steel pipe is preferred over many other steel pipes. Better corrosion and rust resistance is the primary reason why they are chosen for residential and commercial applications. Here are a few other benefits that you will get with a galvanized steel pipe.

1. Improved Pressure Ratings

Galvanized steel pipes are known for their improved pressure rating. Due to this, the pipe will withstand higher liquid substance pressures. Calculating the galvanized steel pipe pressure is also very convenient as compared to any other kind of pipe. The extra protective coating of a galvanized pipe makes it an expensive pipe than others. However, you will get many additional advantages in the price you pay for a galvanized pipe. Therefore, if an improved pressure rating is essential, you must opt for a galvanized steel pipe.

2. Durable Wall and Good Shape

The additional zinc coating on a galvanized steel pipe makes the pipe uniform and thick from every side. So, using a galvanized steel pipe eliminates the chances of leakage and loss of liquid substances like water. Welding a pipe includes forming processes, such as stress and heat, which can impact things inside a steel pipe. However, you can avoid such issues by using a BS1387 galvanized steel pipe.

3. More Strength

Another benefit of a galvanized steel pipe is its better strength than other types of steel pipes. These pipes provide enhanced strength to the construction. Whatever you want to transport using a galvanized pipe will always ensure the highest strength, better support, and steady performance. Strength is an essential element of any construction, so you should choose a galvanized pipe to provide more strength.

You can replace every single old pipe in your building with galvanized pipes. These pipes will last for many decades due to their strength, rust resistance, corrosion resistance, and solid steel material. By replacing your old pipes, you will be able to restore the water pressure and flow fully. It will also minimize the risks of contamination in potable water.

Choosing the Right Plumbing Pipe

Different factors impact the selection of piping material and pipe. Before selecting your galvanized steel pipe, you must compare the pros and cons of the different pipe materials. It is also essential to learn about the possible risks associated with material compatibility. You also need to know about corrosion risks in domestic and hydronic piping systems. Apart from galvanized, the various other plumbing pipes include:

  • Stainless steel
  • PEX
  • Copper
  • PVC
  • Brass
  • Cast iron piping

All the above-listed plumbing pipes come with different advantages and also possible downsides. Whether you choose a BS1387 galvanized steel pipe or any other type we listed above, you must make sure you are selecting the most appropriate option. Before you choose one, you must compare all cons and pros of all plumbing pipes available. It will help you choose the most suitable plumbing pipe for your application.

 

Conclusion

Galvanized steel pipes are the most suitable steel pipes for applications where corrosion resistance and rust resistance are essential. You can replace your old commercial and residential plumbing pipes with new galvanized steel pipes.

High-quality galvanized pipes are durable, and they last for many decades, making them an affordable steep pipe product in the long run.
