In the petrochemical industry, which is a mining and experimental industry, either there is no problem, and once there is a problem, it is a big problem. Therefore, the safety of production is the most important. API certificate is our requirement for security. In the petrochemical industry, especially the highly corrosive chemical industry, it is necessary to use a large number of Teflon products to transport materials, which is a necessary condition to ensure long-term safe production. Teflon hoses and fluorine-lined joints not only meet the functional needs of users, but also achieve excellent performance in cleanliness and durability. …

   Stress crack acidification is called acid stress. In acid pressure construction, if acid pressure is used directly, acid is not only a pressure crack fluid, but also a liquid that reacts with the rock wall of pressure cracks; if non-reactive pre-hydraulic pressure cracks are used, the acid will flow along the water Cracks flow and react with cracked walls. Because of the uneven ground, the reaction between the cracked wall and the acid is irregular. This acid-etched rock wall will form an acid-etched earthworm hole with high conductivity after the fracture is closed, thereby improving the seepage capacity of…

Confirm selection of hose suitable for conveying steamThe category of the hose should be printed not only on the packaging, but also on the body of the hose in the form of a trademarkTo correctly identify the area where the steam pipe is useda) What is the pressure of the steamb) Whether the maximum working pressure can be reachedc) What is the temperature of the steamd) What is the humidity and dryness of the steame) how often is usedf) What are the external conditions for the hoseSpilled and corrosive chemicals attached to the hose have a destructive effect on the…

   EPDM rubber is a copolymer of ethylene, propylene and a small amount of non-conjugated diene. It only contains unsaturated double bonds in the side chain, so it has excellent aging resistance such as ozone resistance, heat resistance and weather resistance. Foreskin and high-voltage, ultra-high-voltage insulating materials. It can also manufacture light-colored products such as shoes and sanitary products. The natural color usually said in the industry refers to black.Nitrile-butadiene rubber (NBR) is a copolymer of acrylonitrile and butadiene monomers. It is mainly produced by low-temperature emulsion polymerization. It has excellent oil resistance, high wear resistance, good heat resistance and…

   In the chemical industry, products with super wear-resistant and corrosion-resistant solvents, or materials such as petroleum, are often transported, so a hose with good acid resistance, corrosion resistance, or oil resistance must be used as the conveying medium. At present, the most widely used acid-resistant, super-wear-resistant and corrosion-resistant hoses in the industry are made of UPE (ultra-high molecular polyethylene) lining materials.   So what is a UPE hose?  Upe is the English abbreviation of ultra-high molecular weight polyethylene. It is a kind of hose with a variety of excellent properties. Its density is lower than that of water, and its…

   Large-diameter hose products are also one of the categories of hoses. We know that hoses are complex in variety, diverse in structure, and in different conditions of use. Therefore, the service life of the hose depends not only on the quality, but also on the correct use. maintainance. The same is true for the application of large-diameter hoses. In order to use them correctly and achieve better application effects, the following points should be paid attention to when using them:  1. Under normal circumstances, the temperature of the medium conveyed by the hose and the hose assembly should not…

   The safety of hydrogen has always been a concern. So far, hydrogen has been used by humans for more than 100 years. The global chemical plants and refineries use more than 60 million tons of hydrogen every year. The proportion of safety accidents caused by hydrogen is extremely low.In terms of cost, hydrogen production from fossil fuels is currently cheaper than hydrogen production from solar and wind energy, and with the development of renewable energy, its cost may be lower than that of fossil fuel hydrogen production in the next 10 or 20 years.   The hydrogen industry chain is…

   On May 14th, a qualified API 16C hose must meet three conditions, one is full diameter, one is fire resistance (705°C open flame), and the third is hydrogen sulfide (H2S). Litong API 16C hose is based on meeting the above three conditions. Various options have been added to the inner layer of the hose above. In addition to hydrogenated nitrile, UHMWPE/PTFE is a highly acid-resistant, abrasion/high temperature resistant material that has been creatively used in the manufacture of Liton API 16C hoses, providing more opportunities for molding. Letone’s R&D department will make great strides in the field of high-performance…

   MT98 mining steel wire braided rubber hose is mainly used in the coal mining industry to transport mineral oil, water-based hydraulic oil or water. The inside of the pipe body is made of synthetic rubber with good oil resistance, and the outer layer is made of black oil-resistant oil. , Weather-resistant, wear-resistant synthetic rubber, this type of pipe can work in the environment of minus 40, but the maximum temperature cannot exceed 100 degrees Celsius; according to the different environmental requirements of customers, the middle layer is woven with one or more layers. High-strength steel wire for reinforcement. In…

   240PSI food and beverage suction and discharge hose is usually used for food and beverage absorption and discharge, specially used for red wine, beer and alcoholic beverages (with alcohol content not exceeding 95%), the hose can use 5% soda water or steam at 226℉ (+130 ℃) temperature for 30 minutes, but it is not recommended for dry abrasives. The rubber inside the tube body is made of white non-toxic CIIR rubber, which meets FDA and 3A requirements in terms of technology. Another feature of the tube body is anti-extrusion Pressure, can continue to operate under the environment of constant…
