wear-resisting Oil resistant hose Acid and alkali resistance: there is no obvious change after soaking in 44 solutions for 24 hours; Pressure resistance: under the pressure of 52.5 MPa, the pressure is stable for 5 minutes without leakage, the surface of the pipe body is not deformed, and the damage pressure is greater than 105 MPa; Heat preservation: place the pipe in an environment of 300-50 ℃, with clear water in the pipe for 20 minutes, and the temperature ratio inside and outside the pipe is 1:40. The wear-resistant sand blasting hose is a material conveying pipe. The wear-resistant sand blasting hose is a material conveying pipe. Common black, yellowish or transparent; Most of them are wrapped by external rubber packing belt, and the steel wire is usually set between the internal and external rubber for negative pressure operation. The utility model is mainly used for conveying liquid containing solid particles such as particles, gravel, cement, quicksand, concrete, gypsum, etc., and is suitable for various tunnel projects, shafts, tunnels, and other engineering operations. The inner rubber and outer rubber of sand blasting pipe made of ordinary materials are usually made of wear-resistant materials, most of which are nitrile rubber (acrylonitrile butadiene copolymer), styrene butadiene rubber (oil extended styrene butadiene rubber), etc., Or PARA rubber (trefoil rubber), the inlet hose has better performance. According to the working conditions and the degree of loss of material particles to the transmission medium, the sand blasting pipe is generally divided into light sand blasting pipe and heavy sand blasting pipe. Spiral wire will make them suitable for negative pressure environment. Light sandblasting pipe Light sandblasting pipe Light sandblasting pipe is usually used in marine sandblasting and quicksand operations. The ordinary inner rubber is made of wear-resistant nitrile rubber (NBR), while the outer rubber is wrapped with composite rubber. Heavy sandblasting pipe Heavy sandblasting pipe Heavy sandblasting pipe is used for sandblasting sand, pebble, mud, etc. Equipment. Oil resistant hose Price Sand blasting vacuum tube Sand blasting vacuum tube The sand blasting vacuum tube is embedded with spiral steel wire, and the general vacuum negative pressure can reach 0.9 bar. Common parameter definitions The wear-resistant sandblasting pipe generally has the following parameters: folding pressure is generally within 12 bar, higher sandblasting pressure can reach 36 bar, and sometimes vacuum negative pressure parameters such as 0.8 bar~0.9 bar are required.

I, wear-resisting Oil resistant hose Quantitative display of quality. In the evaluation plan prepared by the Ministry of Health and Social Insurance for the medical and health system, some indicators were put forward for the service quality of the hospital, such as the number of deaths before and after the operation, the number of unplanned rehospitalization, the infection rate of patients in the hospital, and the immunization rate. It can be seen that the quantification of quality is to reflect the quality of things through a series of quantitative analysis and synthesis. Sand blasting hose enterprises use public opinion polls to measure benefits and service quality. Since the purpose of administrative activities is to meet the needs of society or the public, the best way to measure the social effect and quality is to face the service objects, understand their evaluation and their satisfaction. Although popular, public opinion polls also have limitations, such as high cost, which is difficult to be accurate and reliable due to the influence of public judgment. In addition, the satisfaction of beneficiaries does not answer the question - is this service provided to those who need it most? III, Oil resistant hose Price Administrative departments and public service institutions with single business nature. For those departments that have applied the quality assurance system, their performance evaluation only pays attention to efficiency and economy.

I believe everyone is familiar with wear-resisting Oil resistant hose Relevant application knowledge of products. It is understood that at present, this product is mainly used for mining hydraulic support and oilfield development. It is applicable to engineering construction, lifting transportation, metallurgical forging, mining equipment, ships, injection molding machinery, agricultural machinery, various machine tools, mechanization of various industrial departments, water-based liquids, etc. And liquid transmission. Its relatively high working pressure can reach 70-120 MPa. In order to achieve better application effect, what problems should be paid attention to when using high-pressure braided hose? 1. The bending radius shall not be less than the given bending radius to prevent damage to the hose skeleton or premature failure due to excessive tension. 2. Select the type and specification of the hose correctly according to the use conditions, and do not misuse or replace it. 3. When using high-pressure braided hose, the pressure should be adjusted slowly and evenly to avoid sudden pressure increase and damage to the pipe body. 4. When the work site changes, it should be removed from the ground without dragging, so as to avoid the skeleton layer being corroded after scratching the outer glue. 5. After delivering corrosive liquid, the interior should be cleaned to prevent residues from corroding the pipe body for a long time, or select corresponding series of products. When storing high-pressure braided rubber hoses, depending on the type of rubber used, Oil resistant hose Price Note which conditions typically change over time. However, due to several factors or a combination of several factors, this change may accelerate, and other materials used to strengthen high-pressure braided hoses may also be adversely affected by improper storage conditions.

sunshine 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 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, 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.

sunshine wear-resisting In places that must be crossed or may rub with the mechanical surface when working, hose clamps or springs and other protective devices should be used to prevent the outer layer of the sandblasting hose from being damaged. Sand blasting hose shall be arranged to avoid heat source as far as possible and away from the performance of engine exhaust pipe. If necessary, sleeve or protective screen can be used to prevent the hose from being heated and deteriorated. When the sand blasting hose must be bent, the bending radius should not be too small, and should be greater than 9 times the outer diameter. There should be a straight line section greater than 2 times the outer diameter of the pipe at the joint between the rubber hose and the joint. How high-quality the products and equipment we use are, it is inevitable that there will be some large and small failures in the process of using them, which will more or less have a certain impact on our work. Just like the use of sandblasting hose, there are traces of its outer adhesive seam, problems must be solved, For this, we explained the following solutions: First, the used water cloth should be used according to the original elastic edge of the water cloth when it is reused. 2： When we wrap the water cloth around the seam of the sandblasting hose, we should apply sufficient and uniform pressure to the pipe body. 3. The water cloth with different widths should be selected according to the size of the outer diameter of the wrapped sandblasting hose (for hose with an outer diameter of less than 30mm, the width of the water cloth should not exceed 90mm). The overlapping width of the water cloth should be 3/5-2/3 of the width of the water cloth.
