Shangrao Oil resistant hose The entry threshold is low, the industry market is mixed, and small enterprises with small scale, lack of core competitiveness and low technical level can be seen everywhere. Most of these enterprises lack brand awareness, and there are many brand names and unlicensed products. It is difficult to form enterprise influence through brands, and it is more difficult to improve product added value through brands. If the metal hose wants to take the road of high-end, it must improve both inside and outside. A good brand image promotion and influence building can certainly provide a strong driving force for the development of enterprises, but the source of this driving force lies in the high quality of the metal hose products themselves. Tongfeng Metal Hose said that in the future, domestic metal hose products will focus on high precision, high efficiency, high firmness, multi-function, multi specification, multi variety standardization, serialization and generalization to show their characteristics. One of the main reasons why China's metal hoses have been in the low-end state for a long time is the lack of independent research and development of products. On the one hand, the homogenization competition is serious. In order to win consumers, metal hose enterprises have long focused on low-cost competition and low price shopping. As a result, many enterprises only focus on the production and marketing of low-end products, ignoring the upgrading and innovation of product technology. on the other hand, Oil resistant hose Price ZHUANLI's weak awareness of protection and the serious phenomenon of technology plagiarism and infringement in the industry make the technology cost invested by many enterprises more than worth the cost, which has seriously hit the enthusiasm of metal hose enterprises for innovation.
Shangrao Oil resistant hose It is a kind of hose that can be used for sand pumping and sand suction produced with high abrasion resistant rubber. It is often used in sand blasting industry, cement, steel, minerals and other industries, but it is mainly used in river dredging, slurry transportation in mines, sand digging and sand taking and other industries to transport sharp granular solids or solid-liquid mixtures. Its product structure is composed of high wear-resistant layer, reinforced water pipe layer, skeleton steel wire and outer rubber. Today, Myers will introduce the application field of wear-resistant sand absorption rubber pipe. When the wear-resistant sand suction rubber pipe is applied in the mine pit, it is necessary to set a floating boat equipped with a sand pump in the mine pit, and use the floating sand suction rubber pipe to connect with the sand pump. The floating boat will float up and down with the rise and fall of the water level. It is required that the pipe body has good flexibility and good tear resistance and bending resistance. The offshore pipeline is connected by non floating sand suction hose until the pulp transportation destination. The overall pipeline is divided into two parts, one for surface use and the other for onshore use. The main raw material of these two kinds of hoses is high abrasion and corrosion resistant rubber, and cord reinforcement layer and steel wire skeleton layer are added in the pipe wall to ensure the pressure resistance and tear resistance of the hose. The connection mode is vulcanized flange connection, that is, the flange and the hose are a whole, so there is no need to worry about the flange falling off. Floating sand suction hose used on the water surface. This kind of hose is required to float on the water surface. Due to the large drop of the mine (100 meters) and the long conveying distance Oil resistant hose Price The hose shall have high pressure resistance, and the design pressure is 25 kg/cm2 according to the calculation. It should be considered that the floating ship will move up and down with the rise and fall of the water level and the wave will cause lateral displacement. Its internal structure is the same as the sand suction hose used offshore, except that a floating body is installed outside the hose.
Shangrao Oil resistant hose The structure is composed of liquid resistant synthetic rubber inner rubber layer, medium rubber layer, I or II or III steel wire braid reinforcement layer, and weather resistant synthetic rubber outer rubber layer.

Working pressure of sand suction hose and mud discharge pipe: positive pressure: 10kg; Test pressure: working negative pressure of 15kg steel ring sand suction hose: ≥ 15kg sand suction hose has strong flexibility, which is mainly used as the sand pump sand discharge pipe to connect the sand transport pipe and sand pump, as well as the pipe connection bend.
Shangrao production Oil resistant hose Plays an important role. In the application of different industries, according to their own needs, check the performance of the products, give proper play to the advantages of the products, and ensure the normal use of daily applications. When replacing the wear-resistant sand blasting pipe, the length of the rubber pipe, the number of steel wire layers, the shape and size of the joint should be reasonable, and the curvature of the rubber pipe should be minimized. When tightening the connecting nuts, do not tighten the rubber hose. Excessive bending and twisting will greatly reduce the service life of the rubber hose. Protective measures shall be taken for the parts liable to friction to prevent the rubber hose from bursting due to wear. What should we pay attention to when purchasing wear-resistant sandblasting pipe? Different types of wear-resistant sand blasting pipes have different working pressures. When purchasing rubber hose, you should first determine the working pressure of the system, Oil resistant hose Price Then select the equivalent working pressure of the hose. If the system is often affected by pressure, it is necessary to increase the working pressure of the hose and choose the hose with higher pulse life. The inner diameter of wear-resistant sand blasting pipe is one of the factors to be considered when selecting rubber hose. The small inner diameter will increase the flow rate of the medium, raise the temperature of the system, reduce the working efficiency, and affect the working performance of the system. The large inner diameter will increase the purchase cost. Therefore, the proper inner diameter should be selected according to the flow rate of the medium. The wear-resistant sand blasting pipe has allowable operating temperature range. The service life and pressure bearing capacity of the rubber pipe can be guaranteed only when it works at an appropriate temperature. When the operating temperature of the equipment exceeds the allowable temperature range of the rubber hose for a long time, special rubber hose shall be purchased or special protective sleeve shall be added on the wear-resistant sand blasting pipe. If the medium to be transported is special, make sure that the hose material is compatible with the medium.
