Special hose for furnace door cooling, in the customer's use environment, especially in harsh working environments such as steel plants, glass factories or foundries, large-diameter hoses used for de-temperature delivery of cooling water to the furnace door, because of its harsh The use environment requires that the hose must be adapted to its high temperature external environment. The place where the hose is connected to the equipment is generally connected with a special joint. We know that rubber will become soft when it reaches a certain temperature. If there is no way to deal with the consequences of high temperature, there will be great hidden dangers in the use of the product. There are various types of industrial hoses, which are widely used in petroleum, chemical, energy, construction, steel, machinery, food, medicine and other fields. The Litong PTFE rubber-plastic composite multi-functional hose is undoubtedly the "handler" in the industrial hose. It is not afraid of high temperature, the high temperature of 220 ℃ is its daily work, and occasionally it is as high as 260 ℃. Almost all media can be safely transported through it, even corrosive fluid chemicals (sulfuric acid, hydrochloric acid, sulfur reactants, etc.) cannot attack it. Matters needing attention in the use of ultra-high pressure resin pipes: First of all, under the current conditions of high cost, synthetic resin pipes do have the advantage of improving the quality and reducing the cost. In terms of the oil resistance and aging resistance of the hose : The ultra-high pressure resin tube adopts polymer materials such as nylon and polyurethane elastomer, and the service life is greatly improved. Litong has purchased a lot of imported hardware facilities, built various testing laboratories, blasting laboratories, smoke laboratories, low temperature laboratories, flame retardant laboratories and other top domestic laboratories, providing logistical support for employees to produce high-quality products. The laboratory established under the strong support of Litong's leadership, all kinds of raw materials and semi-finished products are subject to qualification inspection here, which provides favorable conditions for us to produce more perfect products, and try to eliminate product quality problems in the production process. EPDM steam hose assemblies have robust construction for full steam service in chemical plants, refineries, shipyards and industrial services. Recommended for cleaning, defrosting, steam pumps and other applications involving steam. High temperature heat resistant flexible EPDM steam hoses are used in steel plants, refineries, chemical plants and other applications that require high strength and harsh environmental conditions for cleaning, thermal control, fire protection, steam pumps, elevators and other applications. Constructed of black EPDM, smooth finish, reinforced with needled cover wire braid. Taking into account the reserves, production processes and costs of the above-mentioned oil fields, the world is currently exploiting oil that is profitable at current prices, while in oil fields with high costs, such as shale oil, if one day, shale oil can be sold in large quantities, Then these countries that have broken through the technology will surely be able to successfully over-exploit these difficult-to-exploit energy sources. The location of the oil reservoir is different, and the exploitation is difficult. The types of oil fields mainly include onshore conventional oil fields, offshore conventional oil fields, and unconventional oil fields. At present, the proven oil and gas fields are on the rise as a whole, but some oil and gas fields have not been developed.
