Poly Pipe Irrigation Fittings

Polyethylene and polypropylene are the most widely consumed polymers and are in the group of thermoplastic and semi-crystalline polyolefins, which are widely used in various industries.In many industries, both can be used, but you may have been wondering what the difference is between these two polymers. Knowing them can make the best choice for your industry. The two polymers originate from their monomeric unit. The monomeric units of polyethylene and polypropylene are ethylene and propylene, respectively. The main differences between these two polymers are as follows: 1- Polypropylene is more rigid than polyethylene and is most commonly used in the manufacture of molded parts 2- Resistance Polypropylene cracking is high but polyethylene is somewhat elastic and has more flexibility.3- Due to low crystallization speed, presence of nucleogenic agents will be effective while in polyethylene due to high crystallization rate, presence Nuclear agents are of little effect. Therefore, in polypropylene it is possible to produce more transparent product. Nuclear masterbatches are used in polypropylene for this purpose.4- Polypropylene films are more printable than polyethylene, and polyethylene printing is only possible if surface modifications are possible.

5- Polypropylene is used in the manufacture of structural plastics and fibers and its melting point is higher than polyethylene.6- Polypropylene has high fatigue resistance and is used in the manufacture of hinges. On the other hand, polyethylene is more robust and has more physical properties in that it is more resistant to cold; hence it is used in the manufacture of symptoms.7- Polypropylene’s chemical resistance to organic solvents, acids and electrolytes is very high. More than polyethylene.8- Polyethylene is a good electrical insulator because its static load is lower than polypropylene; therefore, the use of antistatic masterbatches for polypropylene based products is recommended.9- Very simple polypropylene production It is difficult and it is possible to produce it with high purity. But in polyethylene, its linear type is difficult to produce, and the high purity end product is produced under controlled conditions.10- When using these two types of polymers, polyethylene is usually used 100% pure but poly Propylene is generally copolymerized with polyethylene. This copolymer is flexible and used in the manufacture of synthetic paper. This paper is durable and resistant to water and tear.11 The main application of polypropylene is in the automotive and food packaging industries. Polyethylene is also widely used in pipe manufacturing, home appliances and carpet and carpet production.12- Polyethylene is a biocompatible polymer and is recycled better than polypropylene.

The three most important uses of polyethylene and polypropylene polymers are in the pipe, packaging and flooring industries of plastic wood. Plastic pipes are classified. Plastic pipes are also divided into six separate polyethylene, polypropylene, hard or chlorinated polyvinyl chloride, polybutylene and acrylonitrile butadiene styrene. PE – (polyethylene) pipes: These pipes are dark or black are. Polyethylene pipes are resistant to the pressure caused by fluid. PE pipes are used in the municipal water distribution network due to their high pressure tolerance. PP – (polypropylene) pipes: These pipes are available in white or green color and due to their unique properties in water supply of small systems and in Wastewater is in use. PP pipes are high fluid pressure resistant and have a wide temperature range and are therefore used in both hot and cold water systems.

In traditional plumbing systems, every 20 feet of pipe, a male and female joint, insulated with a gasket, can be installed as a point of service for possible maintenance. Metalware is subject to corrosion and must be constantly maintained throughout its life. A polyethylene pipeline with welded joints is not only resistant to corrosion and chemicals, but also has a leak-free joint between 40 and 50 ft and tightly seals the pipe itself. The unexpected and the rare ones brought about by third parties provide a system without maintenance. In the event of third party damage to PE pipes, we need to use repair methods to restore the pipeline to operating condition as soon as possible. It is not possible to move the pipe to the restrained facility, such as buried pipes. Permanent repair of restrained tubes requires techniques that do not require longitudinal displacements, such as the use of flanges or flanged structures, mechanical couplings or electrophysics.

One of the many options for system users to make repairs is to use full-blown screw clamps. These types of repair clamps have proven to be a good method for temporary repairs, especially in emergencies. – The use of full-length screw clamps is only recommended in repairs where the pipe is able to maintain its integrity. Use this method only in repairing holes with a clean, round cut surface, deep scratches, or holes less than one-third the nominal diameter of the pipe. Do not use screw clamps in cracked pipes, jagged holes, long ruptures, and deep scratches or holes that can spread out of the clamp due to loads. – Recommended maximum working parameters Do not exceed the manufacturer, including pressure and temperature. – The installer should always follow the installation instructions recommended by the clamp manufacturer. Wherever possible use products specifically designed to work with PE pipes.- If the clamp is not specifically designed for use with PE pipes, you should contact the manufacturer about its use on the pipe. When repairing a PE pipe by a full-blown screw, the effect of pipe movement due to thermal expansion and shrinkage, creep and compressive oscillations should be taken into account. Diversion is used in underground applications. Contact your clamp manufacturer if your usage is different. Establish.

Minor repairs at the repair site using saddle welding

If the size of the puncture injury is very small (about 1 inch or smaller and on a pipe wall), a high-volume non-capillary or a high-volume self-destructor can be used at the site of injury. He connected to the main pipe, assuming we could stop the flow of water and keep the repair site dry during the repair process. Before adding a patch or attachment, pierce both sides of the affected site to prevent further crack propagation. Disconnect the flow of water and prepare the area around the injury for the welding process. Weld the saddle piece to the affected area using the general instructions and allow the joint to cool. Wait 30 minutes and then restart the water flow. Repair by Electrofusion Welding: As long as the water flow can be stopped and the area under repair is dry during the repair process, an electrophysiological patch can also be used. Used to repair minor injuries (3-inch joints or smaller in a pipe wall). Use electro fusion and welding equipment recommended by the manufacturer. Repair using mechanical fittings: In some cases where the injury is minor but severely involved the pipe can cut off the flow of the pipe, a small part He cut the pipe and installed a mechanical coupling in the affected area. Some of the couplings are self-contained and some are not. Some require the use of a stainless steel metal pad inside the PE pipe, and some do not.

Pressurized mechanical joints for polyethylene pipes or tubes are commonly used to repair damage to small (2-inch or smaller) water pipes. . If the injury is a small incision or puncture, the tube can be cut at the site of injury and a pressure joint may be installed between the two ends of the tube. As we know about larger pipes, a certain amount of pipes must be removed to use this method to allow them to bend and mount the couplings. If the damage is wider, a piece of pipe will be cut and replaced with a piece of pipe and two pressure joints. The appropriate flange and support ring are selected and used for repairs. Remove the damaged pipe from the plumbing system. Make sure the length is sufficient to mount the flange assembly. The flange head is then welded to the main pipe and the replacement pipe properly and then the replacement pipe is inserted into the damaged part. Repair by Electrophoresis Massager: This method is very similar to the method used by the flange massager, but It uses a different method of welding technology to create a leak-free connection. Instead of butt-welding the pipes to the flange base, electro-fusion couplings are used to attach the tubing to the current intact tube.

In intubation using polyethylene pipes, there may be cases that require shorter cuts than the existing branches. In these cases, the cut should be made by cutting part of the existing branch length. The cutting should be done in such a way that the ends of the cut are complete and healthy and will not be damaged. For cutting, devices must be used to create at least a cut and a chip in place. After cutting, it is necessary to use a suitable sohan to completely cut the surface of the cut and remove all the cuts and chips to prepare for butt welding. Before installing, inside and outside of each branch simply And the top of the appliance must be clean and dry. The contractor can, depending on the local conditions and facilities, divide the intubation operations into the desired path and divide the number of branches and belongings in each. The piece shall be interconnected, together with the dimensions, the number and intervals of the timbers and shall act as a criterion after obtaining the approval of the consulting engineer. Installation of the polyethylene pipeline is intended to be flange type, as well as installation of valves in other pressure lines. If these valves are of a different type, then the polyethylene conversion that converts this to flange connection can be used. Before hydrostatic testing of the installed lines begins, it is necessary to fill and tighten the soil around the pipe with appropriate soil, so that the line remains in place and does not shake due to internal pressure during the tests. The rest of the preliminary embankment should also be done according to the design specifications. Primary embankment shall be filled around polyethylene pipe and shall be uniformly laminated. The minimum embankment height shall be 30 cm above the pipe crest and, in exceptional circumstances, this amount shall be applicable at least in accordance with the design specifications and arrangements required. The general wash of the line should be carried out after the test and disinfection, with clean water containing chlorine with a concentration of injection into drinking water.
