coupling pe plumbing fitting | Newest Pipe Fittings On Global Market For Sale

Polyethylene pipes are a new type of pipes made of polyethylene raw materials in various commercial grades. Polyethylene is a very simple polymer used in the plastics industry. The most important application of PE is in the manufacture of gas and water supply pipes and fittings. Primary polyethylene is produced under the ethylene polymerization process in the presence of catalysts in the petroleum refinery. Polyethylene is used in the manufacture of all kinds of plastic utensils including kitchen utensils, plastic containers, tanks, garbage bags and so on. Although plastic pipes, such as PVC pipes, are still used in industry, polyethylene pipes have more common applications than PVC pipes. In this article we talk about coupling pe plumbing fitting.


What are the best pipes for homes?

Polyethylene plastic pipes and fittings are widely used today to transport various types of gases and liquids. Polyethylene is preferred over metal because of its inherent advantages such as light weight, high flexibility, easy installation and non-changeable nature. In addition, polyethylene pipe fittings are usually less expensive and more corrosive and flake resistant than other pipes. In the past due to the chemical reaction of the ingredients of old and traditional fittings, there were negative effects on the smell, color and taste of drinking water. There are many types of pipe fittings in markets.

For this reason, extensive research has been done on selecting the best pipes for pipeline water transfer and the results show the high performance of copper pipes as well as high density polyethylene (pe pipe fittings) pipes in this area. In this regard, the EPA regulates standards and regulations regarding the levels of pollution in drinking water distribution systems. Drinking water standards include a long list of pollutants and the maximum permitted level (maximum level of contamination or MCL) for drinking water.

How man types of pipes and fittings are there?

It is widely reported around the world that HDPE (High Density Polyethylene Tubes) is one of the best and safe plastics to use for food storage and water transfer, and no evidence of widespread health problems. No use has been found in the use of hdpe fittings in food and drink programs and drinking water. It can also be said that due to the complexity of the types of contaminants present when observing and reporting water contamination, by modifying the formulations for polymer tube manufacturing and the different planning conditions, the chemical risks of the reactions in the pipes are minimized.

It should be noted that there are pros and cons to choosing any materials for drinking water piping, but recent research shows that the risk of chemical contamination of copper pipes is lower than that of polyethylene pipes. The cost of using it is high and not cost effective. On the other hand, PE reduces costs, is resistant to change in current, and reduces disruption and leakage. Polyethylene pipes also offer the benefits of easy installation and environmental benefits of copper. The polyethylene pipe seller must guarantee the pipes in terms of chemical changes, odor and taste changes as well as good performance against high temperatures.

Who is the biggest pipe producer around the world?

The polyethylene pipe manufacturing plant must modernize its machinery and these lines must be equipped with a Gravimetric & Ultrasonic Weight and Weight Control System. Quality control laboratories are an essential part of any PE production plant and fittings, where laboratory equipment should always be reviewed. Highlights of a PE Pipe Factory:

  • The manufacturer must consider itself responsible for meeting the needs of the highest quality customers.
  • Customer orientation is our motto and customer pride is the priority of customer relationships.
  • The manufacturer values ​​customer time and speeds up the delivery of the best and highest quality products and services.
  • The manufacturer designs and offers its products based on customer needs and upgrades with their opinions.
  • The manufacturer commits itself to having the highest quality standards in customer service.
  • The human resources producer considers the most important asset and the key factor for organizational growth and excellence.
  • The manufacturer believes in teamwork.
  • The manufacturer considers its success in sustainable development and environmental protection and always considers environmental protection to be of value to itself.

Explain manufacturing process of pipes in factories

Until about thirty years ago, the extruders were manually fed. The granules were poured directly into the extruder hopper. Increasingly, the production capacity of the extruders increased as well as the need to reduce production costs using automated feed systems. The system consists of a set of pipes and a compressor or a blower, which transports the material to the hopper using air or vacuum from the silo. This system can operate on the basis of suction, pressure, and a combination of pressure and suction for one or more extruders simultaneously. One of the most important features of these systems is the ability to feed to different locations of the salon using a blower or central compressor. You can see pe pipe fittings catalogue in many websites. 

Today, modern manufacturing plants use central suction systems to feed their extruder machines. The method of determining the amount of input material in terms of speed of production is called the extruder. Depending on the accuracy of production, both volume and weight measurement systems are used. Volumetric metering system based on volumetric flow rate controls the amount of granule volume entered into the extruder. This inexpensive system is easy to operate but relatively low precision.

Can we use PE pipes in our homes?

Wastewater conveyance (Wastewater system) is very important for the collection of surface water or industrial wastewater in large industrial complexes because the penetration of fluid into the deep soil can cause an irreparable impact on underground bases and facilities. Corrosion, rust and soil contamination are the most important causes of water collection and industrial wastewater. Polyethylene pipe, polyethylene fittings and polyethylene manhole Pars Ethylene Kish with anti-corrosion and chemical resistance properties is a good solution for the collection and transfer of sewage sludge. Urban sewage is transported by underground pipes. Polyethylene carbonate tubes and polyethylene spiral tubes, because of their design, have a good cyclic resistance to the application of underground loads with minimum slope and the lowest possible weight, which reduces the cost of the pipe and ultimately the cost of wastewater transportation. Double wall polyethylene pipes (spiral and carogite) are also lighter in technical specifications than single wall polyethylene pipes and can be used as low-pressure polyethylene pipes for sewage and / or sewage transport. Use similar fluids.

How do you connect different size PVC pipes?

The method of bonding in PE and PE depends on the pipeline application, requirements and project conditions. Electrofusion joints are commonly used in gas distribution networks. Electro fusion fittings are in accordance with the recommendations of National Iranian Gas Company and German DIN standard. Butt welding joints are used in water and wastewater systems and their distribution network, fire extinguishing at various pressures. This type of welding is the best way to bond to the PE pipe and joints if done correctly. In welding joints, the quality and efficiency of the welding depends on the skill and ability of the welder, the suitability and efficiency of the welding machine and related equipment, and the compliance with welding principles and rules. Polyethylene screw joints are used in water and sewer lines at pressures below 4 times. The screw joints are easily and quickly opened and closed and do not damage the polyethylene pipes and fittings and are also completely resistant to chemicals.

Concerning the methods of PE connection, it is important to note a few points. Pipes and fittings for polyethylene pipes must be manufactured in standard form. The performance of PE pipes and fittings in the piping system shall be in accordance with the welding standards; all procedures for pipe fitting and installation shall be supervised by experts and contractors. Welding instructions for PE welding should be followed throughout the welding process. Safety issues will also be very effective in increasing the efficiency of workers. The slightest flaw in the implementation of the PE connection can lead to disruption to the pipeline and its destruction; most importantly, all pipe welding equipment must be safely transported and maintained.

What is the difference between coupling and adapter?

coupling can be a coupling reducer, which means that by coupling a larger tube to a smaller size, it reduces the current. Different types of adapters are used when connecting two pipes. For example, an adapter can be mounted at the end of a simple tube to accommodate the connection on the other side of the adapter. Heat welding or polyethylene tube welding electrofusion is performed in three ways: butt welding, saddle welding and socket welding. In all pipe welding methods, the two ends of the pipe are exposed to a specific heat and then the flow of molten material is mixed and boiled at the welding site. If the welding is done correctly, the joint will not leak.

One of the most varied methods of welding a polyethylene tube is called an electro fusion. In this method, the current flows through the two conductive electrodes and the heat generated by the two electrodes is applied to the junction. Electrofusion welding equipment is a bit complicated but will have much higher efficiency. Mechanical coupling must be careful to fasten the joints in place; compressive coupling, screw coupling and flanges are the most important mechanical couplings of PE.

What is a coupling fitting?

Normally couplings do not allow the shafts to be disassembled during operation, although torque limiting couplings can slip or break when the torque exceeds a certain level. The primary purpose of the couplings is to connect the two rotating parts, while allowing them to deviate. Careful selection, installation, and maintenance of the couplings can save a great deal on maintenance costs and downtime. Shaft couplings are used in machinery for various purposes, the most common of which are:

  • Provide shaft connection to separately manufactured devices such as motors and generators, as well as disconnect during repairs or shifts.
  • Allows shaft alignment and mechanical flexibility
  • Reduce sudden transitions from one shaft to another
  • Overload protection
  • Change the vibrational properties of rotary equipment
  • Driver section connection
  • Power transfer from one end to the other (eg motor power to pump in coupling)

What is a slip coupling used for?

Clutch or pressure couplings are two pieces that are attached to the two shafts to form a pod. These couplings are more flexible than sheath models and can be used for fixed shafts. They are usually large enough that the screw can pass through the entire coupling and enter the second half to ensure safe holding. Rigid flange couplings are designed for heavy loads or industrial equipment. These couplings consist of short sheaths formed by a perpendicular flange. A coupling is mounted on each shaft and thus two flanges are facing each other. Then some bolts or bolts can be mounted on the flanges to fit together. Because of their size and durability, flange units can be used to align the shafts before connecting them. Rigid couplings are used when the shaft alignment is required. Shaft malfunction affects performance as well as coupling life.

Sheath couplings are also known as box couplings. In this case, the ends of the shafts are coupled to each other and covered by a sheath. A collapsing thug holds the two shafts together and sheaves together. Sheath couplings are the simplest type of couplings, usually made of cast iron. These couplings consist of a hollow tube piece with an inner diameter equal to the shaft diameter. The pipe is arranged on both ends of the shaft with the help of a cone-shaped submerged spur. Thorns and sheaths are suitable for transferring power from one shaft to another.

In recent years, polyethylene pipes have been widely used in various ways. Flexible couplings are used to transfer torque from one shaft to another when two shafts are slightly angled. Flexible couplings can accommodate up to 3 degree and slightly parallel alignments. In addition they can be used for vibration attenuation or noise reduction. This coupling protects the shaft parts of the driver against the harmful effects produced by shaft malfunction, sudden force, expansion or shaft vibration, and so on. This coupling is a modified flanged coupling and its protected type. This type of coupling has a pin and is coupled to a bolt. Rubber or leather bushings are used on pins. The coupling has two halves with different structure. The pins are fastened to one flange by one nut and loosened on the other flange. These couplings are used to connect shafts with a small parallel, angular or axial deflection. In this coupling, the rubber bush absorbs shocks and vibrations during operation. These couplings are commonly used for coupling electric motors and mechanical machines.
