As the water supply equipment for fire hydrant, fire hose plays an indispensable role in fire fighting. Polyurethane layflat hose is made of high strength polyester filament skin and polyurethane lining. The high quality polyurethane lining has the characteristics of super toughness, wear resistance, acid and alkali resistance and aging resistance. The outer skin is made of thickened warp and weft, which greatly strengthens the bearing capacity of the water hose. Polyurethane layflat hose has a wide range of usage from urban sewage, engineering construction water delivery to pump matching. In addition, with the characteristics of light weight and strong pressure bearing capacity, it replaces the traditional PVC coated water hose in agricultural irrigation projects. Instructions to fire hose use 1) When the water hose is sheathed on the interface, it shall be padded with a soft layer for protection, and then tied tightly with galvanized iron wire or hose hoop. 2) Preven...

What material is PU? PU is the abbreviation of polyurethane. PU, an artificial material, is a high molecular polymer, commonly known as PU, “皮优”. At present, polyurethane material is the best thermal insulation material in the world. This material has good oil resistance, toughness, wear resistance, aging resistance and adhesion. Materials suitable for a wide temperature range (-50 ~ 150℃) can be made of different raw materials, including elastomers, thermoplastic resins and thermosetting resins. What material is polyurethane layflat hose made of? PU hose is polyurethane layflat hose. It is a hose with high strength polyester filament as the outer skin and with polyurethane as the lining. PU hose has a higher price than PVC hose. The hose produced by Suzhou Haifeng Trading Co., Ltd. is a kind of belt leather, which uses high-strength polyester filament and high-quality polyurethane as raw materials. The belt leather is woven by a circular loom and then vulcanized by a high-pressur...

The maintenance of PU water hose should pay attention to the following aspects: ① Management. Special personnel shall be assigned to manage, classify according to quality, number and record, and master the quality and use of water hose in time. Establish and improve the water hose maintenance system, and regularly educate all staff to abide by it consciously. ② Storage. A special storage place or storage room shall be set up. For long-term storage, the standby water hose shall be stored in a place suitable for temperature and ventilation. The water hose shall be rolled up on a single layer and put it on the water hose frame, turning twice a year or exchanged for folding once. The water hose with the car shall avoid friction with each other, and the folding edge shall be exchanged if necessary. ③ Usage. When laying, avoid sudden twists and turns. After filling water, avoid dragging on the ground and contact with corrosive chemicals such as oil, acid and alkali. In areas whe...

There are many types of products that need to be used in daily operation. In terms of tube products, it is a kind of product that needs to be used in daily life. It belongs to an important type of conveying supplies, and now it is widely used, no matter in large fields or small fields. With the progress of production technology, there are many types of pipe products. In this way, they will be able to meet more needs, and their performance will be better, so as to bring a lot of advantages for the actual operation. In terms of PVC steel wire pipe, it is a type of pipe products usually used widely. From its names, we can also know the relevant information. The most obvious thing is to know that it is a pipe product made of PVC material and steel wire material. These two kinds of materials belong to the raw materials with good performance, which will also make the use performance of the finished products better, so as to bring a lot of advantages for the actual use. PVC steel wire pi...

PVC steel wire hose is made of the latest PVC reinforced material, which has good improvements in both compressive capacity and hardness. It can replace ordinary rubber pipe, PE pipe and some metal pipes. PVC steel wire hose is widely used in many industries, such as chemical industry, national defense, manufacturing and so on. It has become one of the most widely used products. PVC steel wire hose is also known as PVC steel wire reinforced pipe. The pipe material is three-layer structure. The inner and outer layers are PVC soft plastic, and the middle layer is steel wire reinforced structure, or steel wire mesh or spiral steel wire. Therefore, the pipe material formed has a number of names: PVC steel wire pipe, PVC steel wire reinforced pipe, PVC steel wire spiral reinforced pipe, PVC steel wire mesh reinforced hose, PVC steel wire mesh hose, etc. In fact, the inner reinforced steel wire layer causes some changes of PVC pipe in the strength, distortion resistance, quality or othe...

Agricultural irrigation methods can be generally divided into traditional surface irrigation, general sprinkler irrigation and micro irrigation. Now with the improvement of people’s awareness of energy conservation and environmental protection, the irrigation methods have undergone tremendous changes. The emergence of irrigation methods such as micro-spray belts and drip irrigation belts has gradually replaced traditional methods. Today I will talk about the PVC irrigation discharge hose commonly used in agricultural irrigation. (1) PVC pipe has excellent acid, alkali and corrosion resistance, which is very suitable for the use in the chemical industry; PVC pipe has a smooth wall surface, small fluid resistance, and its roughness coefficient is only 0.009, which is lower than other pipes. Under the same flow rate, the pipe diameter can be reduced. PVC pipe has high water pressure resistance, external pressure resistance and impact resistance, which is suitable for piping engineeri...

PVC fiber reinforced hose is made of high-quality PVC resin and environmental friendly plasticizer by polymerization and extrusion. There is polyester reinforced line in the middle. It is transparent, non-toxic and tasteless, pressure resistant, tensile resistant, corrosion resistant and aging resistant, weak acid and alkali resistant, beautiful in appearance, soft and light. PVC fiber reinforced hose is soft PVC for the inner and outer layer, polyester fiber and non-toxic hose for the middle layer, it is soft a year round, and it has medium pressure, tensile resistance, acid and alkali corrosion resistance, beautiful appearance, softness, lightness and durable characteristics, can be normally used in the temperature range of -5—+ 65 ℃ . Fiber reinforced PVC hose is basically the same as the common PVC hose, which is also made of PVC resin as the main material, and then extruded with a certain proportion of plasticizer, stabilizer, lubricant and some other auxiliary materials. F...
