Advantages of using polyethylene gas pipes Polyethylene pipes have many advantages, but we will discuss the important advantages here 1. Long pipe life Polyethylene gas supply pipe has a lifespan of 50 to 100 years, which means a reduction in maintenance costs. 2. Resistant to corrosion and the effects of chemical and physical substances Gas supply polyethylene pipes have a very high chemical resistance. They are very resistant to chemical compounds, rodents and alkaline fluids. 3. High flexibility of gas supply polyethylene pipes Polyethylene gas supply pipes can be bent up to 25 times the diameter of the pipe, which in many cases does not require connection to change the angle of the pipeline. On the other hand, the flexibility of gas supply polyethylene pipes in earthquake-prone areas is justified Is. 4. Easy connection of polyethylene gas supply pipes Polyethylene gas pipes are easily connected to each other. This is if other gas supply pipes are difficult to connect and usually have high leakage, this advantage is very important in the transmission of high pressure lines. 5. Affordable price compared to steel pipes Low price of polyethylene gas pipes 6. Ability to squat gas polyethylene pipes Polyethylene gas pipes can be squashed during the project if there is a defect Polyethylene gas supply pipe of Mehravand Mashhad company Disadvantages of gas-fired polyethylene pipes Polyethylene pipes in general do not have special disadvantages, but here are a few of them 1. Gas polyethylene pipes may be damaged and scratched during transportation, which is why the gas pipes have a special packaging. 2. Polyethylene pipes do not have anti-flammability properties and fire ignites quickly on the pipe during fire. 3. Pressure drop for a long time Gas polyethylene fittings In general, there are two types of connections Electrofusion welding Melt boiling lead The advantage of electrofusion welds 1. High flexibility 2. Easy and fast connection 3. High strength against earthquakes and landslides 4. Resistance to corrosion and chemicals 5. 100% insulation 6. Electrofusion joints made of PE100 and compression class 16 times and different sizes from size 20 to 250 Types of electrofusion connections Tube to tube Tube to knee Tube to bubble Melt boiling head to head In welded joints, in head-to-head welding, in which a special connection called a coupler, which has an electrical resistance system, is used to generate the heat needed to melt the weld surface.

Drip irrigation tape is one of the pressurized irrigation equipments which is usually used for row crops such as greenhouses, potato, corn and ،, with type tapes for surface and subsurface irrigation (shallow). Used, each roll of tape type usually starts from one thousand meters. The material of type tape, unlike hard polyethylene pipes, is very soft and quite flexible. Type tape is also known as drip irrigation tape. Mehravand Mashhad Company, using modern European technology and high quality raw materials, produces drip irrigation tape or plate type (QUEEN DRIP) in two diameters of 16 and 22 mm. Their thickness is from 15 to 200 microns. Mehravand Company type tapes are among the highest quality type tapes available in the Iranian market, which have product quality approval from the Deputy of Water and Soil, Mechanization Center and the Ministry of Jihad Agriculture. Types of irrigation tapes Irrigation type tapes are generally divided into three categories 1. Sewing or sewing armbands There is a seam or side seam tape of zigzag path next to it 2.Placed tape The tape type has a flat dropper. 3. Striped tape It has a strip in the middle of the brigade. In this section, we must write the specifications of the plate irrigation tape Drip irrigation tape or tip Uses of drip irrigation tape Field green space, greenhouses suitable for growing chickpeas, lentils, beans, mung bean, peas Great for growing grains such as wheat, barley and rice. Suitable for summer and vegetable products such as potatoes, watermelon, onions, squash, eggplant, cauliflower and lettuce, carrots, cucumbers, eggplants Or other plants such as sugar beet, cotton, sugarcane, soybean, sunflower, corn, canola Types of soil in choosing the right type of tape 10 and 20 cm type sandy or sandy soils Ordinary soils of 20 to 30 cm type tape Heavy engineering clay soils 30 to 40 cm A few tips for farmers to choose the right agricultural type bar 1. Farmers whose lands have saline water should pay attention to the fact that saline water leads to clogging of the holes in the type strip. 2. Meet the plant's water needs correctly 3. Do not apply the type tape with a slope above 2%, as its efficiency and uniformity will decrease. 4. Drip irrigation tape can be applied at a depth of 5 to 15 cm. 5. Use filtration system 120. Tip tape maintenance tips for farmers 1. When implementing the tape type project, the tape should not be pulled on the ground as sharp objects and various thorns will cause the tip tape to puncture. 2. Do not cut off the water immediately after the fertilization operation and let the water flow in the drip irrigation network for about 30 minutes so that the toxins left in the tap strip are completely drained. 3. Measure the pressure behind the dropper continuously and periodically 4. In case of clogging, open the end of the pipe path and pour the appropriate clogging acid for the washing operation 5. When installing, be sure to keep the end of the path closed 6. If the brigade is damaged, use the interface for repair 7. After the installation and execution process is over, open the ends of the letters and connect the current to clear the path. 8. Avoid storing irrigation type tapes in non-roofed space, especially when exposed to sunlight for a long time. 9. In areas where the wind speed is strong and causes the tape to move, you should fix the type tapes with a plastic nail at a suitable distance. 10. If your ground temperature changes a lot, the tape should be installed underground 11. If your land has a lot of hail during the season, it is better to use strips under the soil. 12. If the water in your area is salty, you should use a filter to prevent clogging of the seams and drippers Advantages of drip irrigation tape 1. Easy and fast installation 2. Convenient carrying of the bar due to its light weight 3. Ability to install on the ground and underground 4. Very high savings in water consumption and increasing the area under cultivation 5. Increase crop utilization and prevent the spread and growth of weeds in the soil 6. Non-adhesion of algae and mineral sediments due to special polymeric material 7. Having the same flow rate and very small difference in flow rate during the letters 8. Product quality uniformity 9. Improve product performance 10. Can be used on non-flat lands The discharge of QUEEN DRIP strips is usually from / 8. Liter to 2.6 liters per hour. QUEEN DRIP irrigation tape features Manufactured with modern European technology High anti-clogging resistance The power of the droppers Has a high coefficient of uniformity (CU) and uniformity of distribution (EU) (92% -96%) Has a coefficient of variation of less than 3% in the drippers for uniform distribution of water in the irrigation strip Can be used in 2 working seasons Possibility to change the distance of the droppers from 10 to 120 cm Production of 22 mm type to create uniform water supply capability in laterals with a length of more than 200 meters Drip irrigation tape or tip A few tips about type tapes 1. Collect the tape at the end of the growing season After the end of the exploitation period, the type tapes should be collected from the field surface so as not to contaminate the field, these tapes can be used for replanting. 2. Collect the irrigation tape of the type that is under the soil dry If you have used the type tape under the soil, it is better to irrigate the agricultural irrigation type tapes once for convenience and not to damage them, so that the soil on the tape becomes moist and soft.
