Whenever the topic of transferring fluids comes up, we undoubtedly think of connections and pipes. Today, with the progress that has been made in the field of producing suitable tools for transfers, it is easy to see connections in different types and types in the market. One of the types of fittings available in the market are polyethylene fittings. The issue that we are going to talk about in this text is exactly related to this. In this article, polyethylene fittings, their applications and their types will be explained and described.
What are the connections of polyethylene?
When it comes to transmission by means of polyethylene pipes, without a doubt we must also talk about connections. Polyethylene fittings are actually parts and equipment used in pipelines and installations. In fact, the purpose of using these connections is to change the piping diameter, change the liquid flow rate in the pipe, connect the pipes together and change the angle at which the fluid is moving.
An important point that It is good to know about this type of connections that they can connect parts without the need for welding or using other tools such as bolts and nuts. In fact, the connection process in this type will be done with the help of a nut.
You should know that polyethylene connections are produced under DIN16963 standards and have different types. The DIN standard is one of the strictest standards in Germany, and most manufacturers in the world go to this type of standard to produce their products. Usually, the price of each of these connections is determined based on their use and quality.
Polyethylene fittings Features
One of the most important features and advantages that can be mentioned about polyethylene joints is the high speed of installation.
Another feature of these joints is their high resistance to breakage and cracking caused by external pressures. .
These joints have high resistance to corrosion and abrasion, for this reason, they can be considered to have a long useful life.
These joints also show high resistance to chemicals such as acid and base.
Low cost in execution and installation is also one of the other characteristics and specifications of this type of connection, which can be very interesting and important depending on the conditions.
In areas that are part of earthquake-prone areas, these connections show great durability and stability and are very resistant to vibrations caused by earthquakes. It is not heavy. Usually these pieces are not attacked by vermin; Because there are no nutrients in them.
These pipes have many advantages and for this reason, they are used in many facilities today, including rural and urban piping networks and even industries.
Pipes are widely used in agricultural fields. Especially in rain and drip irrigation methods, these types of connections show high efficiency.
Types of Polyethylene Fittings
Different types and types of polyethylene joints are available in the market and each of them is selected and used based on their application. In the continuation of this text, we are going to explain and introduce the types of polyethylene joints. So stay with us to get to know the types of these connections.
screw or gear or threaded joints
One of the types of polyethylene joints is screw or rib or threaded joints. These connections consist of components such as o-rings, body, head screw, oscillating ring and bushing and can withstand a pressure of up to 10 atmospheres. One of the significant advantages of this type of connection is the ability to open and close it multiple times. are used. The following types of screw connections can be mentioned:
- سه راه مساوی
- سه راه نر
- سه راه ماده
- زانو نر
- زانو مساوی
- زانو ماده
- رابط مساوی
- رابط نر
- رابط ماده
- تبدیل و درپوش انتهایی
Gas Fittings or Electrofigen
Among other types of polyethylene connections, gas connection or electrofusion can be mentioned. They use electric welding to connect different parts with the help of electrofusion. For this reason, more precision and resistance can be observed in the type of connection. Gas connections are used in industries such as oil, petrochemical and gas supply. A higher reliability factor can be seen in this type of connections.
welding joints
Another type of polyethylene joints is high pressure welding joints. This type of connection is connected butt to polyethylene pipe and it can be used in industries such as fire fighting and water and sewage industries. This type of connection also includes tees, elbows, conversions, flanges, PP.STEIL rings and conversions. This type of connection can be produced according to the needs and requests of the customer. Among the advantages of this type of connection are light weight, easy installation, their pre-fabrication, high resistance to chemicals, resistance to against temperature changes and so on.
Polyethylene Belt
Polyethylene belt can be mentioned among other types of polyethylene joints. In places where it is necessary to branch off from the main pipes or where reconstruction is needed, this type of connection can be of considerable help. Different materials are used in the construction of this type of connection. And for this reason, it can be seen in the market in different genders. This belt consists of two parts, the branch and the bottom. This belt is closed around the polyethylene pipes by means of a screw.
Flupes Foundings
Flange joints can be mentioned among other types of polyethylene joints. In this type of connection, the pipes are connected with the help of round steel plates, which are called fanledges. One of the most important points that can be mentioned about this type of connection is their ability to be bolted. Flanges are connected with the help of bolts and nuts and this process can have advantages in its place. It is good to know that flange connections have high resistance and for this reason in gas transmission industries and in general in They are widely used in the gas industry.
Drop irrigation joints
- آبپاش
- درپیر
- بابلر
- شیر خودکار
- شیر توپی
- سر شلنگ
- زانو 16
- شیر انشعاب
- فیلتر دیسکی و توری
injectable joints
Among polyethylene joints, injection joints can be mentioned. To produce connections of this type, first a mold must be made and then by plastic injection machines, polyethylene materials are injected into these molds and the required connection is also provided.
Among the advantages and features of this type Connection can be referred to their integrity and high strength. In addition, since this type of connection is made in the form of a mold, they are completely uniform in terms of size and dimensions, which is very significant in this case.
sewage connections
Other polyethylene connections that should be mentioned are sewer connections. This type of joints are butt-welded and are used to connect and change the direction in sewer pipes.
Polymer Connections
Another type of polyethylene joints can be referred to polymer joints. This type of connection is available in different types such as uPVC, polypropylene and cPVC and they are used in different industries according to the existing applications and needs. This type of connection is widely used in places such as refineries and irrigation of green spaces.
