Phenolic resin pipe insulation tubes, resin tube, German crown Rubber Products

Note the use of hose hose varieties due to the complex structure of diverse, coupled with different conditions, so the hose length of life, not only on their quality resin tube looking 宁津宏 Xiang also decide on the correct use and maintenance. So even if there is a very high quality product, if not properly used and maintained, will seriously affect the quality and longevity of their use, or even should not have a serious accident, causing damage to property. Now available using the following precautions: 1, hose and hose assemblies designed only for transporting materials, otherwise it will reduce the life or failure. 2, the proper use of the hose length, hose changes length at high pressure (-4% - + 2%) and the change in length due to mechanical motion. 3, hose and hose assemblies should not be used in excess of the design working pressure (including shock pressure). 4, under the hose and hose assembly conveyed medium temperature normal circumstances, should not exceed -40 ℃ - + 120 ℃, otherwise it will reduce the service life. 5, hose and hose assemblies should not be less than the minimum bend radius under the hose, to avoid bending or folding occurs near pipe joints, otherwise it will hinder the hydraulic transmission and delivery of materials or damage to the hose assembly. 6, hose and hose assemblies, should not be used in the reverse state. 7, hose and hose assemblies should be handled with care and should not drag on the sharp and rough surface, not bending and flattening. 8, hose and hose assemblies should be kept clean, the interior should be clean (especially acid transport tube, spray tube, mortar tubes). Prevent foreign objects into the lumen, hindering the transmission fluid, damage to equipment. May continue to be used after 9 over the service period or shelf life of the hose and hose assembly to conduct experimental identification. 1. Hose transport hose during loading and unloading, the following points should be noted that the hose during loading and unloading, to do light loading and unloading. Hose reel require classification (Article) neat shipment, to avoid excessive bending of the tube discount should not heap pressure on the hose other heavy objects. Do hose with acids, alkalis, oils and organic solvents, flammable materials mixed; tube should not be in direct contact with the sharp edge of the cargo. For transportation needs straight hose, when the length exceeds the load compartment, the long part of the bracket should be supported to prevent damage to the hose on the ground dragged rub. If for some reason when the hose temporarily parked in the open air (or workshop pier), the venue must be smooth, flat hose should be neat and underlying superstructure do not stack ballast; at the same time, the hose is not in contact with the heat source. When handling the hose should not drag anywhere epoxy pipe corrosion, should be used for heavy lifting equipment hoses or special handling equipment, and to prevent accidental damage to the hose. 2. hose storage (1) Storage warehouse hose should be kept clean, airy, relative humidity below 80%, the temperature inside the warehouse should be kept between -15 ~ + 40 ° C, and avoid the hose by the sun direct and snow Baptist leaching. (2) when the hose storage, should be placed under the different varieties and specifications were not mixed stack, and in order to get access badges. (3) hose stored in the relaxed state as possible, generally less than the inner diameter of 76mm hose, coil can be stored (but disk inside diameter shall be not less than 15 times the inside diameter of the hose) (4) In order to prevent the hose storage time tube compression deformation, stacking is not too high, generally stack height should not exceed 1.5m; and require the hose during storage often "down stack", generally at least once every quarter. (5) hose storage, not with acids, alkalis, oils and organic solvents or other corrosive liquids, gases, contact; and shall be derived from the heat than 1m (6) hose during storage, non-stacked on the tube weight, and to prevent damage to the outside world and squeeze. (7) hose during storage, generally not exceeding two years, and should be used before storage, first use, to prevent the hose storage for too long and affect quality. Mining method correctly detected high pressure hose pressure test according to the requirements of high-pressure hose pressure is two times the working pressure, burst pressure is generally 3-4 times the working pressure is qualified, packing three minutes. On this in terms of how to detect the pressure of it, the first is the appearance, if its brightness is good and has a lot of flexibility on the part of top grade then, secondly, mining high-pressure hose pressure test is mainly divided into low and high voltage test test. Mining test pressure Low pressure hose testing is 1MPA, packing five minutes phenolic resin pipe insulation tubes, test medium is water. If you did not find the tube of liquid leakage, is qualified. Mine pressure hose high pressure testing the same test medium is water. If there is no blasting, is qualified. Also do high pressure burst test, pay attention to the surrounding environment, to detect pressure equipment should be placed in a closed environment. Miscellaneous prohibit people walking. In order to avoid unnecessary injuries. After detecting the resin tube, which in normal use, it should be noted that the use of stainless steel metal hose should first make the hose as far as possible away from the heat radiating member, fashion necessary insulation boards; hose should avoid external damage, such as using the same components Long-term friction surface; reduce oil viscosity, easily lead to leakage, reduced efficiency; reduce lubricant film strength, speed mechanical wear; generate carbide and silt ballast; oil oxidation deterioration accelerated oil; oil seals, high pressure hose premature aging and so on. These are some of the knowledge about high-pressure hose and hope for your help wondering, if you want to know more, please contact us.
