It is difficult to choose the right spraynozzle for your application. There are a variety of nozzle sizes and types, each designed to perform different functions.
The following information will help you choose the right spray nozzle for your job. We will be comparing steel and plastic spray nozzles, which are the two most commonly used. Let’s get started!
How do I choose the right nozzle material?
Before we get into the steel vs. plastic nozzles debate, let’s first define some important factors that should be considered when choosing a nozzle material. These include temperature, corrosion, abrasion and cost.
1. Temperature
Your options will be narrowed based on the environment in which your tank cleaning nozzle will operate. Temperature is the first thing to consider. Each material will melt or soften at specific temperatures. Some materials are more able to withstand extreme temperatures like high heat.
It is important to remember that spray nozzles will operate in extreme temperatures.
2. Corrosion
Corrosion is a common problem over time. The type of media used to spray can also accelerate the corrosion process. Certain nozzle materials, however, are resistant to corrosion and can be used in highly-corrosive environments.
3. Abrasion
Chemicals such as acids, alcohol, and oxides can cause abrasion. This is why abrasion resistance is so important. These environments require that your nozzle material is strong enough to withstand the abrasive effects from powerful chemicals. Certain materials are better suited for such situations.
4. Cost
Spray nozzles should be selected based on cost. In the long-term, however, the most economical option may not be the best. Materials that resist corrosion are more expensive, but will last longer and won’t require replacement as often, which ultimately saves time and money.
Steel vs. Plastic Nozzles
Steel Spray Nozzles
We will first look at steel nozzles and how they fit in each of the four categories.
Temperature: The stainless steel nozzles can be used in hot environments. Steel nozzles are a common hard material and can withstand temperatures above 285 degrees. A stainless steel nozzle might be the best choice if you live in a hot environment.
However, stainless steel nozzles can be corroded. They will last for a while, but if you have a high-corrosive environment or require extremely low temperatures, an alternative material might be better.
Abrasion: Stainless steel is not very abrasion-resistant by itself. Steel is an excellent choice for abrasive applications once it has been hardened.
Cost: Stainless steel nozzles are cost-effective if used in the right environment.
Plastic Spray Nozzles
Next, we’ll examine plastic nozzles and how they fit in the above categories.
Temperature: Plastic nozzles do not work well in extremely hot environments. In extreme temperatures, plastic will melt and deform. Stainless steel is the best option in these situations.
Corrosion: Plastic nozzles are very resistant to corrosion. Plastic nozzles are more resistant to corrosion than most metal materials. This is the best feature. A plastic nozzle is a great choice in a highly corrosive environment.
Abrasion: Plastic nozzles can be damaged quickly by abrasive applications and are not suitable for extreme abrasion.
Plastic nozzles can be a cost-effective solution for particularly corrosive applications. They are not cost-effective in other situations, such as extreme heat and abrasion.
What about other nozzle materials?
Plastic and stainless steel aren’t the only options for nozzle materials. Spray nozzles can be made from a variety of metals and other exotic materials, each one suited to a specific application.
This article will not cover every spray nozzle material. However, it will briefly mention brass and silicon carbide as they are both very common materials.
How about brass?
Brass, like steel, can withstand high temperatures. It isn’t often used for corrosive and abrasive chemical.
What about silicon carbide?
Silicon carbide can also be used at high temperatures. Silicon carbide can also be used to spray abrasive chemical and can save money.
How can I prolong the life of my nozzles?
We conduct extensive research to extend the life of spray nozzles. Proper nozzle usage can reduce quality issues, profit loss, and prolong the life of your spray nozzles. Regular maintenance is not necessary. The best nozzle material is the first step to extend nozzle life.
Consider switching to plastic if your application is prone to corrosive chemicals. Your nozzles are made of steel. You can also consider stainless steel if your application uses abrasive chemical and your nozzles are made of plastic. The best nozzle will work for you and your application.
