The oil pipes of Litong brand are divided into the right types. Most people only know crude oil transportation, but few people know the oil return hose. half, suitable for petroleum-based hydraulic oil, water and glycol, flame retardant water-based hydraulic oil, lubricating oil, crude oil, fuel oil and water. Therefore, it has a very wide range of applications and has characteristics such as high temperature resistance.
Introduction to the basic functional characteristics of the steam hose: 1. The working pressure of the steam hose is generally not more than 30 kg, but the burst pressure is generally 10 times the working pressure; 2. The middle reinforcement layer of the steam hose is mostly braided with steel wire or polyester wire. As a manufacturer, we It is recommended to use less cloth, the service life of the cloth is too short, and it is easy to bulge; 3. The service life of the steam hose is generally more than one year. In the petrochemical hose wear-resistant hose, if there is a problem with safety and working pressure Certain requirements, generally used for B type (A, B, C, D pressure from low to high) wear-resistant pipe: its working pressure is about 5MPa ~ 7MPa, usually used for certain safety requirements.
Due to its consideration of cost and safety, its price/performance ratio is relatively moderate. The inner and outer rubber of the hose is made of synthetic rubber, and the wear resistance is guaranteed to a certain extent. Since the reinforcement layer will also use steel wire, the maximum blasting pressure is also improved to a certain extent. 3. Bone-setting method When the ruptured part of the rubber hose is large or about to be broken due to the action of external force (shrapnel breakdown, extrusion rupture) or system overload, the bone-setting method can be used: wipe the ruptured part of the hose and cut off the ruptured part ; Insert the self-made steel "bones" into the cut hose; clamp the hose and the "bones" with a self-made steel plate clip); clean the connected hose and use it.
UPE material, that is, ultra-high molecular weight polyethylene, is a thermoplastic engineering plastic with a molecular weight higher than 1.5 million. With a molecular chain length of 10-20 times that of high-density polyethylene, longer molecular chains (higher molecular weight) give UPE materials the main advantages of toughness, wear resistance and stress crack resistance, because it is polyethylene One, UPE also has lubricity, chemical resistance and excellent electrical properties, and its successful development is generally regarded as one of the top ten scientific and technological achievements in the 20th century.
Ultra-high pressure resin hose refers to a high-pressure hose formed by extruding a plastic material as the inner core and braiding or winding reinforced with high-strength industrial fibers or steel wires. The pipe body is generally divided into three layers: the inner hose layer, the skeleton reinforcement layer and the outer rubber layer. Fiber (steel wire) braided high-pressure resin pipe has the characteristics of light pipe body, high compressive strength, small deformation under pressure, good resistance to media, aging resistance and convenient use.
