Shenyang Cord hose Also called rubber hose for sand blasting. It is suitable for air pressure sand blasting of metal surface for rust removal, hemp removal, and sand blasting rubber hose for wet sand blasting and dry sand blasting in engineering construction. It is suitable for air pressure sand blasting of metal surface for rust removal, hemp removal, and sand blasting rubber hose for wet sand blasting and dry sand blasting in engineering construction. The common application fields are shipbuilding, machining, spraying industry, etc. Appearance of abrasion resistant sand blasting rubber hose: 1. Light abrasion resistant sand blasting rubber hose consists of black, yellowish or transparent abrasion resistant rubber inner layer, central fabric or cord reinforcement layer, medium rubber layer and outer rubber layer; 2. Heavy abrasion resistant rubber hose consists of black, yellowish or transparent abrasion resistant rubber inner layer, cloth clip or cord reinforcement layer, steel wire framework reinforcement layer, medium rubber layer Composition of outer rubber layer 3. The steel wire braided wear-resistant sandblasting hose is composed of black, yellowish or transparent wear-resistant rubber inner layer, single-layer or multi-layer steel wire braided reinforcement layer, medium rubber layer and outer rubber layer. Purpose Abrasion resistant sand blasting hose is a kind of material conveying pipe, which is mainly used for conveying solids containing particles such as particles, gravel, cement, quicksand, mud, gypsum, etc. It is suitable for various tunnel projects, tunnels, caverns and other engineering operations. The general working pressure is less than 12 bar, and the higher bursting pressure can reach 36 bar. Sometimes the vacuum rich negative pressure parameter is 0.8 bar 0.9 bar. Cord hose Price Hydraulic requirements 1. The maximum working pressure of wear-resistant sand blasting hose is 0.63MPa. 2. The hose shall be free from water seepage, local bulge, expansion and other abnormalities when conducting hydraulic test under twice the working pressure. Keep the pressure of anti-static hose for 1min, and the length change shall not exceed ± 0.8%, the outer diameter change shall not exceed ± 10%, and the torsion per meter shall not exceed 60 º. 3. The bursting pressure of the hose shall not be less than 4 times of the working pressure.

Shenyang Cord hose It is used for transportation, construction and other operating equipment. Incorrect operation and incorrect environment may affect the normal use of steel braided sandblasting pipe. What specific factors will affect the normal use of steel braided sand blasting pipe? The quality will definitely affect the use effect. The poor quality is actually related to the selected raw materials. Some raw materials are of high quality, and the quality of steel braided sandblasting pipes produced is also very good. However, if the steel braided sand blasting pipe is made of inferior plastic, the quality is very poor, which also affects the use effect. The use environment affects the use effect. Anti static steel braided sand blasting pipe is usually used in industry. Because these products are very common, the demand is also large. However, people do not pay attention to the use environment. If used in strong acid and alkali environment, steel braided sand blasting pipe will naturally corrode. Or if used in a relatively high temperature area, the steel braided sandblasting pipe may melt. Anti static steel braided sand blasting pipe will also affect the use effect. In the eyes of most users, the greater the degree, the better the nature. So if you choose a good one, users can use it with confidence. Understanding and avoiding the wrong use of high-pressure pipeline can reduce the possibility of high-pressure pipeline failure. The following brief introduction will help you. 1. Frequent and serious pressure shock: high-pressure pipeline burst is generally not caused by excessive static pressure, but is related to the severity and frequency of pressure shock. During the operation of construction machinery, the sudden increase or decrease of oil pressure in the high-pressure pipe will occur repeatedly, which will cause frequent pressure shocks to the oil pipe, leading to the aggravation of oil seal damage at various parts, blistering and cracking of rubber hose, and loosening and leakage of pipe joints. Therefore, during operation, the valve rod shall not be pulled too hard, but must be pulled gently. 2. The use temperature of oil is too high: during the operation of construction machinery, due to the power loss of the hydraulic system, the oil will rise, and the external temperature (especially in summer) will lead to a sharp rise in the oil temperature. production Cord hose Price The higher the oil temperature is, the easier the rubber is to age, the worse the elasticity is, the lower the strength and sealing performance are, and the high-pressure pipe will burst rapidly. Therefore, when the temperature rise of the hydraulic system is too high or too fast during operation, the causes should be found out and eliminated in time. For summer operation, especially continuous operation, necessary cooling measures shall be taken.

Shenyang Cord 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 root 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, Cord 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.
