We are all denominators. Why treat ourselves as molecules. But I think we Acetylene pipe Where can I find it? 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 production Acetylene 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.

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, Acetylene pipe Where can I find it? 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, Lhasa Acetylene 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.

production Acetylene pipe 1. During the molding of rubber products, the cohesive force of the elastomer cannot be eliminated due to the large pressure pressing. During the molding and mold release, extremely unstable shrinkage (the shrinkage rate of rubber varies due to different rubber types) often occurs. It must take a period of time before it can be gentle and stable. Therefore, at the beginning of the design of a rubber product, no matter the formula or the mold, it is necessary to carefully calculate the matching. If not, it is easy to cause dimensional instability of the product, resulting in low product quality. 2. Rubber belongs to thermosetting elastomer, while plastic belongs to thermosetting elastomer. Due to different sulfide types, the temperature range of rubber molding and curing is quite different, even affected by climate change and indoor temperature and humidity. Therefore, the production conditions of rubber products need to be properly adjusted at any time. If not, there may be differences in product quality. 3. The rubber product is the rubber mixture made from rubber raw materials after mixing in the internal mixer as the raw material. The formula is designed according to the characteristics of the required rubber products during mixing, and the required product hardness is determined. The product is molded by the rubber plate vulcanizer. After the product is formed, flash processing shall be carried out to make the product surface smooth without burrs. 4. The aging test of rubber products belongs to the category of aging test. Rubber aging refers to the phenomenon that the performance and structure of rubber and products are changed due to the combined effect of internal and external factors in the process of processing, storage and use, thus losing their use value. Acetylene pipe Where can I find it? It is characterized by cracking, tackiness, hardening, softening, chalking, discoloration, mildew, etc. The following conditions shall be met when the ball mill uses the rubber lining plate: 1. The hardness of the ground material. The iron base alloy is similar to the rubber lining plate for materials below medium hardness, and the rubber lining plate is superior for materials above medium hardness. 2. The temperature of rubber lining plate is generally 70 ℃ - 90 ℃, and it can reach 110-130 ℃ under special circumstances. The temperature should be lower during dry grinding. 3. Feed size. Generally, the ball mill shall be more than 20-25mm; For the autogenous mill, the feeding particle size can be larger because no steel ball is added.

Acetylene pipe Where can I find it? The following recommendations contain a series of precautions to prevent items from aging to a greater extent during storage. 1. During storage, the rotating plan system shall be adopted to shorten the storage time of high-pressure braided hose as much as possible. If long-term storage cannot be avoided and the following recommendations cannot be followed, high-pressure braided hoses should be thoroughly inspected before use. 2. Physical storage conditions: The high-pressure braided hose must be stored without mechanical pressure, including excessive stretching, compression or deformation, and without contact with sharp or sharp objects. High pressure braided hoses should be stored on suitable supports or on dry ground. High pressure braided rubber tubes packaged as coils must be stored horizontally. High pressure braided rubber pipes shall not be stacked. If stacking cannot be avoided, the stacking height shall not cause permanent deformation of the high-pressure braided rubber pipe below. Pumping high-pressure hydraulic hose is a common high-pressure hydraulic hose. In order to ensure the operation safety of the pumped high-pressure hydraulic hose, the following small series will briefly introduce the correct use of the pumped high-pressure hydraulic hose: 1. Before each use of the high-pressure hydraulic hose, the surface of the high-pressure hydraulic hose must be evenly coated with soap liquid, which can play a non bonding role between the high-pressure hydraulic hose and the concrete, and play a lubricating role in the drawing process, It can greatly increase the reuse times of high-pressure hydraulic hoses. 2. Installation: first, insert the steel hinge wire into the inner hole of the draw tube to avoid extrusion deformation when pouring concrete. Then, pull out the high-pressure hydraulic hose coated with soap liquid from the prestressed hole and fix it in the correct position with a fixing ring. The spacing of the retaining rings is controlled by the suspension and is usually about 500 mm. production Acetylene pipe When connecting the high-pressure hydraulic hose, wrap both ends of the high-pressure hydraulic hose for one and a half weeks or two weeks with thin iron sheet or PVC pipe (vertical cutting), fix them with iron wire, and then seal both ends of the PVC pipe with tape to avoid entering the mortar.

one Lhasa Acetylene pipe When using, the talcum powder on the inner wall of the hose must be blown clean to prevent the channel of the welding torch from being blocked. Avoid external extrusion and mechanical damage during use, and do not fold the pipe body. 2. Care must be taken when storing and using the hose to keep it clean and free from damage. For example, avoid exposure to sunlight, rain and snow, and prevent contact with acids, alkalis, oils and other organic solvents that can damage the hose. The storage temperature shall be - 15~40 ℃, and the distance from the heat source shall not be less than 1m. 3. According to the national standards, the oxygen hose is red, the working pressure vessel is 1.5MPa, the inner diameter of the hose is 8mm, and the outer diameter is 18mm; The acetylene hose is black, the working pressure vessel is 0.3MPa, the inner diameter of the hose is 8mm, and the outer diameter is 16mm. 4. The gas cutting operation requires a large oxygen output, so the valves of the gas cylinder (or oxygen pipeline) connected to the high pressure end of the oxygen meter should be fully opened to ensure adequate flow and stable pressure. The low pressure gauge has indicated the working pressure, but the pressure drops suddenly when using oxygen. At this time, it is easy to backfire and may backfire into the oxygen hose to cause explosion. 5. Oxygen hose and acetylene hose shall not be mixed or substituted with each other, and oxygen and hose shall not be used to blow away the blockage of acetylene hose. At the same time, it is necessary to check and eliminate the defects such as gas leakage and blockage of the welding torch at any time to prevent the formation of oxygen and acetylene mixture in the hose. It should be pointed out that the hose color specified in the national standard is opposite to that specified in the international standard (ISO) (oxygen hose is black, acetylene hose is red). At the same time, it is different from the original ministerial standard (HG4-605-66) that oxygen hose is red and acetylene hose is green. Before 1966, domestic oxygen hose was black or green and acetylene hose was red. thus Acetylene pipe Where can I find it? It causes inconsistency between the understanding and habits of the supply department and the user, and is easy to cause accidents due to the mixing and substitution of rubber hoses. At present, it should be emphasized that unified understanding and use should be carried out in accordance with the provisions of national standards, and attention should be paid to distinguishing the rubber hoses of imported equipment.

Although fire Lhasa Acetylene pipe Explosion proof pipe) can be compressed and stretched, but if the installation position is incorrect, it will break quickly and reduce the service life. The sandblasting hose can be installed horizontally, vertically or obliquely. The most ideal condition is vertical installation. At the same time, avoid installing near the wheel, and install baffle if necessary. Generally speaking, the flame spraying metal sand blasting hose (explosion-proof pipe) can be divided into three lengths: the first is the compression length, that is, the length of the sand blasting hose when it is compressed to the limit position; The second is the installation length, that is, the length of the sandblasting hose when it is in the middle of half of the maximum displacement. The third type is the stretching length, that is, the length when the sandblasting hose is stretched to the maximum limit. When installing the sandblasting hose, the sandblasting hose should be in the middle position, which is called the installation length. When installed at this position, the sandblasting hose can move in two directions when bearing axial load. Otherwise, if it can only move in one direction, its strength will be affected and its service life will be reduced. In the actual installation process, considering that measuring the length of the sandblasting hose with a ruler according to the calculation results may affect the production efficiency, some foreign manufacturers directly install the ruler on the sandblasting hose, and cut the ruler after installation. From the structural point of view, the metal flame spraying metal sandblasting hose (explosion-proof pipe) is composed of strip and tube parts, which can form annular flame spraying metal sandblasting hose bellows and spiral flame spraying metal sandblasting hose bellows. Acetylene pipe Where can I find it? Just because the corrugated pipe of the fire sprinkler metal sandblasting hose formed by this article always has a certain length of brazing or welding buckles and fire sprinkler metal sandblasting hose joints, the residues of the working medium often accumulate in these places, and the cleaning test and mechanical impurities in the working medium will deposit down to pollute the inner cavity. Therefore, its use reliability is relatively poor.
