high quality Peristaltic pump pipe 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. Peristaltic pump pipe company 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.

1. The use of protection cannot be ignored: the long-term use of high-pressure sand blasting hose joints at home usually does not cause concern, but excessive use and improper protection also buried the hidden danger of joint cracking to a certain extent. It is understood that the service life of the joint is usually 200000 times, and it should be replaced after long-term use. When using the side, Peristaltic pump pipe company Care should be taken to close and open as gently as possible and not to rotate the knob of the hose connector repeatedly. 2. Differentiation of quality can be based on standard evidence collection. It is understood that it is still difficult to determine the cause of joint cracking. At present, the National Bureau of Technology and Quality Supervision has issued recommendations for sealing nozzles and hose specifications. These two specifications perfectly adjust the quality specification target of connectors and hoses. Consumers can go to the quality inspection department to check the torsional strength of the connecting hose, the tightness of the connecting spool and the strength of the connecting materials. If the content of standard rules cannot be met, it will be attributed to quality problems, which can serve as a strong basis for expression. 3. The appearance of hose connector is difficult to distinguish between good and bad. In order to pursue profits and reduce costs, many manufacturers currently use selected cast iron (easy to rust) and zinc alloy (non anti-corrosion) as materials to produce high-pressure sand blasting hose joints, which causes product quality problems. It is understood that the quality of connectors and hoses is not up to standard, Liaocheng Peristaltic pump pipe The strength function and sealing function of high-pressure sand blasting hose joints are not up to standard due to problems such as materials and wall thickness, which should be paid attention to by consumers.

We are all denominators. Why treat ourselves as molecules. But I think we Peristaltic pump pipe company The mass of is absolutely the molecule in the same industry. From raw materials, the general manager is responsible for the purchase of raw materials. Raw materials can only enter the factory after passing the inspection. Because it is the boss's own purchase and inspection, there is no buyer to take kickback, which increases the cost of raw materials and reduces the quality of raw materials. Speaking of the manufacturer's production process, it is difficult to find the second advanced mixer equipment among the new sand pumping hose manufacturers in 2019. It ensures that our glue is more uniform. This ensures the quality of our sand pumping hose. About 70% of sand pumping hose is manual work, and the production technology experience of workshop workers largely determines the quality of our sand pumping hose. 70% of our workshop workers have more than 7 years of production high quality Peristaltic pump pipe Experience. Select rubber hose Wang Xueyan purchases sand pumping rubber hose, which is more insurance than insurance company. Our goal is to become a member of the hose industry with excellent sand pumping hose quality. Place an order yesterday and deliver it today. At this speed, it is hard to find a second sand pumping hose in the industry. Life doesn't treat us kindly because we are women. But we should treat our own lives well and try to sell sand pumping hoses. As an excellent salesman, will you also receive an inquiry like chicken ribs. When I was just doing business, I received a 3 page quotation, and I patiently sorted it out for about 2 days. Finally, there was no news. Now I have been doing business for more than 10 years. Sometimes I can accurately judge the order rate of this order simply by looking at the inquiry list. The real heart of the words lies in the customers who make good deals.

Due to the limitation of spatial location conditions, high quality Peristaltic pump pipe The installation stress of can often bring various difficulties to the installation work: formed pipes cannot be installed; When you bend down, you are about to come. If you make do with pipes, local cold correction will inevitably occur. According to the size of the pipeline and the specific situation on site, the cold correction amount varies from several millimeters to tens of millimeters, some as high as hundreds of millimeters. Practice has proved that the greater the quantity, the higher the internal stress. These residual installation stresses in the rubber sand blasting pipe are undoubtedly huge hidden information. The lubricating oil duct of a certain type of engine bearing was broken for many times due to excessive installation stress in actual operation. Because it can be bent at will, the internal stress generated by bending under the condition of rated bending radius is very small, which brings great convenience to the installation work, and also plays a certain role in ensuring the safe operation of the rubber sand blasting pipe. This is the main reason why some rubber sand blasting pipes must be used. Since it is necessary to load and unload the mold, the movable cylinder on the vulcanizer will move up and down. After repeated reciprocation, the copper serpentine tube will undergo fatigue fracture. Although it can continue to be used after repair, stopping for repair will cause time loss. Liaocheng Peristaltic pump pipe Although it has good flexibility and strong fatigue resistance, it is also weak in pressure bearing, temperature resistance, aging resistance and other aspects, and can not be used after several months. The good comprehensive performance of rubber sand blasting pipe is fully reflected here.
