Embodiment Construction

[0018] The present invention will be further explained below in conjunction with the drawings, but the protection scope of the present invention is not limited.

[0019] In the description of the present invention, it should be noted that the terms "upper", "lower", "left", "right", "inner", "outer", etc. indicate the orientation or positional relationship based on the drawings. The orientation or positional relationship is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the pointed device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation of the present invention.

[0020] See figure 1 , The present invention provides a technical solution, a special pipe for high-pressure transmission of heat transfer oil, from the inside to the outside, the inner rubber layer 1, the inner skeleton layer 2, the mid...

Abstract

The invention discloses a special conduction oil resistant high pressure conveying pipe. The special conduction oil resistant high pressure conveying pipe sequentially comprises an inner rubber layer,an inner skeleton layer, an inner rubber layer, an outer skeleton layer and an outer rubber layer from interior to exterior. The inner rubber layer is composed of, by weight part, 80-100 parts of inner rubber, 4-6 parts of a plastifying softener, 6-10 parts of cyclohexyl sulfo-phthalimide, 7-12 parts of raw methyl vinyl silicone rubber, 12-18 parts of butadiene-acrylonitrile rubber, 1-5 parts ofcalcium carbonate, 2-4 parts of diethylene glycol, 3-5 parts of carbon black, 2-4 parts of 1,2-ethylene thiourea, 4-8 parts of white oil, 3-7 parts of a fracturing prevention agent, 2-6 parts of fiber, 3-10 parts of lead tetroxide, 2-5 parts of dibutyl phthalate and 1-3 parts of Rhine wax. The special conduction oil resistant high pressure conveying pipe is reasonable in design, simple in structure and long in service and has the advantages of being resistant to oil, high temperature and abrasion, high in tenacity and fracture resistance and resistant to corrosion and aging, and has popularization significance.

Description

Technical field [0001] The invention belongs to the technical field of conveying pipes, and in particular relates to a special pipe for high-pressure conveying of heat-conducting oil. Background technique [0002] The hose structure is usually divided into: inner rubber layer, outer rubber layer and framework layer (or intermediate layer). The inner rubber layer directly bears the wear and erosion of the conveying medium, the outer rubber layer protects the inner body of the hose from damage and erosion from the external environment, and the skeleton layer is the pressure-bearing layer of the hose, giving the pipe body strength and rigidity. Rubber hoses have been used in many areas of life and production. Common pipes include: water pipes, hot water pipes, steam pipes, marine pipes, food and beverage pipes, air pipes, welded pipes, gas pipes, ventilation pipes, material pipes, oil pipes, Chemical tubes, high-pressure tubes, etc. [0003] With the rapid development of my country'...
