Undoubtedly, steel pipes are considered as one of the most used metal pipes in buildings. These pipes can be used in petrochemical, oil, gas, etc. industries with their proper performance in various industrial fields. However, steel pipes do not show high resistance against corrosion and moisture, and to increase their resistance, a coating layer should be used. Steel pipe epoxy paint is one of the types of coatings that are created on steel pipes and increase their resistance. Stay with us to learn more about this type of stainless epoxy paint, its advantages and disadvantages.
What is steel pipe epoxy paint?
Epoxy paint is one of the types of metal paint that can be prepared with two components of resin and hardener. This paint has many applications in various industries, one of which is painting steel pipes. Steel pipes usually do not have a high resistance to moisture and corrosion and may be destroyed due to contact with certain conditions. Steel pipe epoxy paint is actually a type of coating that is placed on steel pipes and will multiply the strength of these pipes. Steel pipe epoxy paint is sprayed on steel pipes with special techniques. After drying, this paint gives a hard and resistant state to the pipe, which can even be washed. Epoxy paints can be made more flexible with different additives and actually perform better when applied to pipes.
Advantages of epoxy paint for steel pipe
Using stainless epoxy paint for steel pipes can be very beneficial because of its very high adhesion. So that this coating prevents water penetration and pipe corrosion. On the other hand, the implementation of this color will bring many advantages compared to other methods of strengthening steel pipes, some of which we will mention below.
Increasing the resistance of steel pipes
Epoxy paint of steel pipes is very durable and can show good resistance against corrosion and water penetration. On the other hand, because these colors have high resistance to temperature, they easily perform well in various industries with high temperature.
High chemical resistance and abrasion resistance
Steel pipe epoxy paint increases the resistance of steel pipes to chemicals. This pipe is resistant to all acidic and alkaline materials and can be considered a very good choice for industries that deal with chemicals.
Affordable price
Epoxy paint, which is used to cover steel pipes, has an affordable price compared to its various features. Therefore, these colors can be used for a wide area of pipes.
Ability to combine with other materials
Many of the properties and characteristics of epoxy are related to its flexibility to be combined with other products. In fact, this color can be combined with various other colors to improve its chemical and mechanical properties. as
Disadvantages of epoxy paint for steel pipe
Despite the advantages and advantages of steel pipe epoxy paint as an anti-rust coating, the disadvantages of this paint are not so noticeable. Metal pipes have low resistance to mechanical factors and may not perform well in wet environments. However, due to the fact that dry weather prevails in most regions of Iran, there is no need to worry about this. To increase the mechanical resistance of these pipes, polyethylene and other coatings can also be used.
How to apply steel pipe epoxy paint
To apply industrial epoxy paint on steel pipes, it is first necessary that the surface of the pipe has been completely cleaned. In this case, the surface will be ready to apply epoxy paint. For this purpose, sandblasting and various devices can be used to remove rust and deposits. After this step, the next steps of applying epoxy paint on steel pipes are done, which include the following.
Combination of two components
The two components of the epoxy paint must be thoroughly mixed together before use. For this, be sure to follow the manufacturer’s instructions for mixing epoxy paints and combine these two components according to the recommended percentage.
Application of paint on the pipe surface
Steel pipe epoxy paint is usually applied on hot pipes in order to benefit from the proper performance of the paint on the surface. Spray equipment can be used to apply epoxy paint. Depending on the type of pipe and its application, it is possible to apply epoxy paint with the number of layers and different thicknesses.
paint drying
After the process of applying the steel pipe epoxy paint is done, you should wait for them to dry before using these pipes. Depending on the type of compounds used and the air temperature, the drying time of epoxy paint is different. Detailed information about the drying of this color will be provided to you by the manufacturer; But it usually takes 72 hours for epoxy paints to dry completely.
Final inspection and control
After drying the epoxy paint on the pipe, the necessary checks must be done to determine the level of adhesion, hardness of the coating, etc., so that finally the epoxy paint can be applied on the pipe according to the requirements and standards.
