The pipe coating technology has been developed as oil and gas pipelines develop. 40 Last year tar coal was the best protector for pipes. Today synthetic resins are used for coating and applied to the pipe in the factory through high-precision processes. Coating is the first off-line coating on the corrosive environment where the pipe is buried.

The second line of defense is cathodic protection, which is a vital element in maintaining and integrating lines. On the other hand, the over current protection causes the coating to deteriorate, and for this reason, to keep the protection current at a safe level, increase the coating efficiency through its correct application on the metal surface prepared. The good performance of the coating depends largely on its adhesion to the metal surface. Its initial adhesion and durability under contact conditions are among the factors that lead to long-lasting coating performance.

Initial adhesion is highly correlated with the flow of coatings and coatings when applied to the coating as well as the cleanliness of the pipe surface.

Plastic pipe structure

Plastic tubes are in Asia made of organic polymers, which behave differently against heat:

1. Thermoplastics: They are often solid at ambient temperature and become soft and ductile with increasing heat. Many plastic pipe materials include polypropylene (P.P), PVC, polyethylene (PE), thermoplastic. Thermoplastics can be reheated and re-heated.

2- Thermosets: With the increase of heat they soften and form. They become solid again and harden, but the thermostats cannot be reheated and transformed into other forms. In fact, they are immutable.

Advantages of plastic or polymer tubes to buy

The properties of plastic pipes depend on the operating conditions, service specifications and fluid used in the raw material. In general, their most important properties are:

Abrasion and corrosion resistance

In general, plastics and therefore pipes made of it have good resistance to corrosive liquids and gases such as acids and salt solutions, etc. However, this resistance is directly related to the concentration of corrosive materials, temperature and pipe used. Slaves and the type of these fluids. For example, polyethylene pipes can transfer 70% sulfuric acid at 23 ° C.

Smooth interior wall

Other properties of plastic tubes are their smooth inner wall, which makes them low in sedimentation, and to a large extent to avoid clogging, blockage and pressure drop. These problems are common in metal pipes, which also cause the rust and taste of liquids inside the pipe.

Heat insufficiency

As you know, the heat transfer capability of the plastic pipes is very low, which minimizes the heat loss, but it is worth noting that the high expansion coefficient of the plastic pipes is one of the disadvantages of these pipes. . For example, PVC pipes expand at least five times the size of the steel, causing it to twist along the path that needs to be considered, and consider the necessary arrangements, such as expanding it further. It requires cost. Plastic pipe tolerances vary between 50 and 150 ° C depending on their type.

Who are the best producers of plastic pipe covers?

Given the increasing use of plastic pipes in the industry and construction of the country, the variety of production and distribution of these pipes with different properties, choosing the right plastic pipe for a particular application makes it a specialized choice based on knowledge and science. Has become. Since the 1930s, when the Germans first used plastic pipes in building installations and to discharge wastewater, plastic pipes have become widely used today.

These pipes have many advantages over metal pipes. Corrosion resistance, low weight, low deposition on the inner surfaces, easier transportation, easy installation of various types of different properties and even more beauty are the most important uses of these pipes over metal pipes.

Needless to say, there are disadvantages to using these pipes, but the variety of their properties can minimize the disadvantages of using a specimen for a particular application. This article examines their various properties that will hopefully help you make the right choice or at least determine the path of choice.

Approximately How many types of pipe covers are around the world?

Types of outer coatings of pipes

The coating is a layer that prevents the body (tube) from interacting with its surroundings. Steel pipe coatings can be one, two or three layers and in some applications the pipe coating is protected with cementitious materials.

Epoxy single and double layer coatings

The epoxy powder adheres to the hot metal surface as a solid and thermo-polymer by chemical reactions. Melting epoxy powder formulation includes hardener, paint, flow controller and stabilizer additives. To apply epoxy powder to the tube surface, first the tube previously cleaned by sand blast or shot blast operation is heated and the epoxy powder is sprayed on the surface by electrostatic gun.

The powder melts and flows in contact with the hot tube, then is geled and cooked to create a coating for corrosion protection. This type of coating has been commercialized since 1960. Epoxy Laminate System In addition to the first layer of epoxy powder used for corrosion protection, the second layer is epoxy fused and is usually applied to the mechanical protection of the pipe. The second layer epoxy is sprayed on the tube immediately after the first layer while the first layer is still active to form chemical bonds between the layers.

Double layer polyolefin coating

Extruded plastic coatings containing adhesive or sealants have been used for corrosion protection since the 1950s. Double layer coatings are very versatile, such as butyl base adhesives and asphalt base butyl or mastic coatings used as the first layer and polyolefins as the second layer and mostly polyethylene or polypropylene. During use, the adhesive is heated to achieve optimum flow and uniform coating on the surface of the tube and immediately coated with polyolefin of appropriate thickness.

Polyolefin three-layer coatings

Three-layer coatings have been in use since the 1980s; polyolefins used as the coatings are often made of polyethylene or polypropylene.

First layer: The epoxy powder used in the first layer plays a major role in protecting the pipe from corrosion. The epoxy powder is applied by an electrostatic gun with a thickness of 80 to 250 micrometers on the surface of the tube previously cleaned by sandblasting and heated for coating operations to be melted by the heat of the tube and cured to form a solid epoxy web.

The second layer is the copolymer adhesive which is extruded on the epoxy layer by a 250 mm thick side extrusion process. The adhesive used should have good chemical adhesion with the bottom epoxy layer and the outer coating.

Third layer (polyethylene): The third layer is applied to protect the pipe from physical damage with a thickness of 1.2 to 3.5 mm by extrusion process. Polyethylene coating is used for conditions where the service temperature fluid is about 80 degrees Celsius.

Third layer (polypropylene): 1.2 to 3.5 mm thick and sometimes 10 mm thick, stretched over the previous layer, with a service temperature of 120 ° C.

Comparison of polyethylene and polypropylene in three-layer coatings

Compared to polyethylene and polypropylene coatings, polypropylene has a higher service temperature and is a good choice for fluid transfer up to 120 degrees Celsius, with better impact resistance than polyethylene and due to higher wear resistance Polyethylene is more suitable for projects that are more likely to be damaged, such as rocky terrain, mountains or drilling operations.

Special Pipe Coatings

All steel pipes used for conveying water, gas, crude oil and other petroleum and petrochemical products require special coatings to extend service life, protect against corrosion and increase efficiency by reducing friction. Fluid with tube body. Crush pipe coatings are divided into two groups: inner and outer coatings. For exterior coatings depending on the location (on soil or buried in soil), suitable color systems are recommended.

PVC pipes have little resistance to forces that can be externally applied. These tubes are not resistant to high temperatures and, if they are too hot, lose their original shape and cause deformation. Also, dry PVC pipes have little resistance to cold and break down in the event of prolonged exposure to cold, so it is quite clear that PVC pipes are a good choice in areas where low air temperatures Is, are not.

Mastic adhesive and its performance in pipe joints: Elastomeric pipe insulators are used more and more today. These insulators are a good alternative to white foam and glass wool. Elastomeric tube insulators come in two types: plain and coated.

There is no simple type of coating. These insulators are mostly used indoors.
Outdoor coated pipe insulation is more commonly used. Because they are more resistant to environmental conditions.

Before insulating the pipe, check the size of the pipe and the amount of insulation required. The thickness of the insulation also depends on its thermal resistance and the water temperature and air temperature. How to insulate glass wool pipes: 1. Stainless steel 2. Glass wool and nylon 2. Apply nylon cardboard 2. Use of mastic, mastic, cross-section and wood glue 2. Paint Tubes 1- Use colored tape and sweep arrows

Anti-Acid Paint: Anti-acid paint can be used to cover metal pipes, concrete and tanks exposed to chemicals and alkalis such as wastewater, industrial waste, etc. Corrosion of concrete and metal surfaces can be predicted for the following reasons: 1: Presence of moisture 2: Heat of the pipes which elevate the activity of bacteria. 3: Alkalinity of concrete which high strengthens the concrete’s resistance to abrasion. 2: RC damage

Concrete Permeability: Permeability is one of the factors that are effective for resisting and adhering to concrete due to the damage that external chemicals can have on penetrating concrete and chemical reactions on cement paste as well as on reinforced concrete. Low durability and rupture of concrete depend on many different factors, so that despite some inadequate quality, the performance of a concrete may be satisfactory, but permeability is one of the parameters that can lead to concrete degradation alone.

Inside or outside the concrete, for example, the penetration of calcium hydroxide from the concrete to the outside and the penetration of water into the concrete which can cause frost and concrete damage. These are some of the things that influence permeability. It also affects the heat transfer properties of concrete. The permeability of cement paste mainly affects the permeability of concrete, but there are pores in the aggregates that exacerbate this phenomenon.
