What type of metal hose is used for irrigation?

Metal hose for irrigation: water is generally passed inside the pipe304 metal hose with ordinary carbon steel flange

The specification of metal hose depends on the safety requirements such as the environmental location of the equipment, the installation of the equipment, high temperature, and the area of flammable materials.

Metal hose for irrigation The pipe is generally watered, and the ordinary carbon steel flange 304 metal hose is used;

Because the main parts of the hose are made of austenitic stainless steel, the hose has excellent temperature resistance and corrosion resistance, and the hose has a wide operating temperature range of -196-600

The hose used can be selected according to the corrosiveness of the medium through which the pipe is passed, and the corrosion resistance of the hose can be guaranteed.

1.The metal hose is made of 1Cr18Ni9Ti stainless steel material as a whole, which has strong corrosion resistance.

2.The hose body is a thin-walled stainless steel pipe body hydroformed, which has strong flexibility, elasticity, strong bending and vibration resistance, and the reinforced protection of the woven mesh sleeve makes it have a higher pressure-bearing capacity. 3.

The connection at both ends of the hose can also be made into other connections except for thread and flange standards, which is convenient for connection and use.

Special metal hose 4This product is not only suitable for matching with rotary joints, but also widely used for flexible connections for the transportation of a variety of fluid media. Corrosion resistance, high temperature resistance, low temperature resistance (-196 +420), light weight, small size, good flexibility.

It is widely used in aviation, aerospace, petroleum, chemical, metallurgy, electric power, papermaking, wood, textile, construction, medicine, food, tobacco, transportation and other industries.

Irrigation pipes: polyvinyl chloride (PVC-U) pipes, polyethylene (PE) pipes and polypropylene (PP-R) pipes.

PE pipes are more ideal

PE pipe specification products are black, the outer wall is inlaid with sky blue band, is the past ten years just recognized by the society, its outstanding advantage is that it has "toughness" and "flexibility", not easy to break, the car can be driven from above can also be restored to the original state, can adapt to complex terrain, save elbows, joints and other accessories, and the price is low, buried in the ground theoretical life of 50 years, is the current more ideal sprinkler and drip irrigation pipeline material.

PVC-U pipe has a fly in the ointment

PVC pipes are still common pipes in the past 20 years, with white and gray, and their advantages are low price, complete specifications of pipe accessories, can be connected with glue, and are easy to install. However, its disadvantage is that it has "hardness" and "brittleness", so it is said that it is a fly in the ointment, and it has been gradually replaced by PE pipes in the pressure piping system.

PP-R pipes should not be used

PP-R pipes are generally white, inlaid with blue or red lines, the pipe wall is very thick, one of its characteristics is that it has "and heat", the use temperature can reach 120, only used for hot and cold water pipes; The second feature is that it is "cold brittle" and has a high price among the three types of plastic pipes, so it is the wrong place to use PP-R in a sprinkler and drip irrigation system.

Steel pipes are only used on bare floors

The advantage of steel pipe is high strength, and its disadvantage is that it has "corrosiveness", affects water quality and short life, and the price is high, and the diameter of 110mm and less than the same caliber pipe, the price of steel pipe is more than 2 times higher. Therefore, galvanized steel pipes are used only for local pipes that cannot be buried in the ground. Galvanized steel pipes are divided into hot-dip and cold-plated, comparatively speaking, hot-dip pipes have good rust resistance, because the coated zinc molecules are densely arranged and the "penetration" of iron molecules is deeper, so hot-dip pipes should be preferred, although the price is slightly higher.

The main differences between agricultural pipes and irrigation pipes are as follows:

1. Different uses: agricultural pipes are mainly used for the production of agricultural rocks, and are used for drainage, irrigation, agricultural machinery, etc.; Irrigation pipes are mainly used for irrigation, which is used to improve soil moisture status and promote crop growth and development.

2. Different materials: agricultural pipes are generally made of PVC, PE, ABS and other materials, while irrigation pipes are mostly made of aluminum alloy, stainless steel, galvanized steel and other jujube materials, which have good corrosion resistance and corrosion resistance.

3. Different structures: the structure of agricultural pipes and irrigation pipes is also different, agricultural pipes generally adopt a single-wall structure, while irrigation pipes are mostly double-walled structures, with good compressive performance.

4. Different: The agricultural pipe is lower than the irrigation pipe, because the material of the agricultural pipe is relatively simple, and the production cost is also lower.

In short, the difference between agricultural pipes and irrigation pipes is mainly manifested in the use, material, structure and other aspects, and it is necessary to choose the right pipe according to the actual situation.

The difference between agricultural pipes and irrigation pipes is: agricultural pipes are used for agricultural production, such as storing and transporting jujube water, liquid fertilizers, irrigation water, and pesticides; The irrigation pipe is used to transport irrigation water to the farmland, which is a necessary facility for irrigation and distribution of old farmers.

1.Different uses: Agricultural drain pipes can be used for irrigation and water supply of agricultural machinery, while irrigation pipes are generally only used for irrigation.

2.The materials are different: agricultural pipes are generally made of steel or plastic, while irrigation pipes are generally made of aluminum alloy or fiberglass.

3.Different sizes: The size of the agricultural pipe is larger than that of the irrigation pipe to meet the needs of agricultural Yanhui machinery.

4.Different: Due to the difference in material and size, agricultural pipes are much more expensive than irrigation pipes.

1. Agricultural pipes: Due to its soft material, agricultural hail pipes can be used for irrigation, drainage, leakage and other purposes.

2. Irrigation pipe: Because the irrigation pipe is made of relatively hard material, it can be sourced to make the water flow rate faster, which can better meet the requirements of irrigation.

Irrigation pipe, also known as pouring pipe, is made of PVC polyvinyl chloride. PVC resin powder is used as the main raw material, an appropriate amount of additives is added, and it is processed and molded by mixing, extrusion, sizing, cutting and flaring pants. Product Features:

1. The flow resistance is small, the roughness is , and the water conveyance capacity is increased by 20% compared with cast iron pipes, and 40% increased by concrete pipes.

2. High tensile strength, tensile strength at 23 is not less than 45MPa.

3. Good compressive resistance, no rupture when pressed to 1 2 of the outer diameter, and good mechanical properties.

4. Light weight, convenient shipment, the specific gravity of PVC-U pipe is only 1 5 of steel cast iron pipe, 1 2 of concrete, 1 4 of the same specification and length of ductile iron pipe, 1 10 low transportation cost of concrete 1 2-1 3.

5. The pipe is hygienic and non-toxic, has no secondary pollution flow, and will not produce secondary pollution to water quality. The service life of the irrigation pipe is not less than 50 years under stable temperature and pressure.

How to achieve scientific irrigation of farmland:

1. PVC irrigation pipe can well comply with the growth process of crop resistance to achieve modern irrigation. The amount of water used for irrigation can be selected according to the specific moisture conditions of crops and soil.

2. The most unique thing about PVC irrigation pipe is that it can realize the irrigation technique of direct water supply and fertilizer supply to the roots of crops according to the characteristics of the current weather. This reduces the hassle of manual work.

3. PVC irrigation pipe can transport more reasonable irrigation water according to the growth needs of crops, which can ensure that crops can be irrigated in a more timely and appropriate manner, and lay a solid foundation for improving the yield of crops.

Standard classification of farmland irrigation:

Class I: water cropping, such as rice, irrigation 800 cubic meters per year.

Category 2: Dry farming, such as wheat, corn, cotton, etc. The irrigation water volume is 300 cubic meters.

Three categories: vegetables, such as Chinese cabbage, leeks, onions, cabbage, etc. The amount of irrigation varies greatly depending on the variety of vegetables, generally 200 500 cubic meters per mu.

The working system of the irrigation system is usually divided into continuous irrigation and rotational irrigation. Continuous irrigation is the simultaneous supply of water to all pipes in the system, that is, the entire irrigation system is irrigated at the same time as a rotational irrigation area. Its advantages are timely irrigation, short running time, and convenient arrangement of other management operations.

The disadvantages are that the main pipe flow is large, the engineering investment is high, the equipment utilization rate is low, and the control area is small. For the vast majority of irrigation systems, in order to reduce engineering investment, improve equipment utilization, and expand irrigation area, the working system of rotational irrigation is generally adopted, that is, the branch pipe is divided into several groups, each group includes one or more valves, and the water supply is supplied to each group in turn through the main pipe during irrigation.

Principles of Rotational Irrigation Group Division:

1) The number of rotational irrigation groups should meet the water demand of crops, and at the same time, the controlled irrigation area should be coordinated with the water supply of the water source.

2) For the system with manual and pump water supply and no equalization device at the head, the total flow rate of each rotation irrigation group should be consistent or similar as much as possible, so as to make the pump run stably, improve the efficiency of the power machine and the pump, and reduce energy consumption.

3) In the same rotation irrigation group, choose a sprinkler head of one type or similar performance, and plant the same lawn variety or similar irrigation requirements.

4) In order to facilitate the operation and management, it is usually best to concentrate the range controlled by a rotation irrigation group. However, the automatic irrigation control system is not subject to this restriction, and often the valves in the same round irrigation group are dispersed to maximize the flow in the main pipe, reduce the small pipe diameter of the medium difference liquid, and reduce the cost.

Scientific irrigation embodies the scientific nature of irrigation, makes the existing water-saving irrigation more scientific, formulates a suitable irrigation system through reasonable irrigation calculation, and maintains it through an effective management system, so that the irrigation purpose is optimized, and the ratio of output value to water consumption reaches the highest point. However, scientific irrigation emphasizes the scientific nature of irrigation, and adds strict scientific basis on the basis of water saving, which mainly includes the following aspects: (1) The scientific nature of the irrigation system.

2) The scientificity of the design scheme. (3) The scientificity of operation management. The irrigation system of crops refers to the number of irrigation times, the date of each irrigation and the irrigation quota of the crop before sowing (or before rice seedling planting) and during the whole growth period.

The irrigation quota refers to the amount of irrigation water on the irrigation area of a single irrigation unit, and the sum of the irrigation quotas is called the irrigation quota. The irrigation quota and irrigation quota are often expressed in m3 mu or mm, which is an important basis for the planning and management of irrigation areas. The irrigation system under the condition of adequate irrigation refers to the irrigation system designed and formulated by the irrigation water supply to fully meet the water demand requirements of crops at all growth stages.
