A type of tubular rubber article used to transport gas, liquid, slurry or granular materials. The large-diameter silicone rubber tube is composed of an inner and outer rubber layer and a skeleton layer, and the material of the skeleton layer can be cotton fiber, various synthetic fibers, carbon fiber or asbestos, steel wire and the like. Generally, the inner and outer rubber layers of the large-diameter silicone rubber tube are made of natural rubber, styrene-butadiene rubber or butadiene rubber; the oil-resistant large-diameter silicone rubber tube is made of neoprene or nitrile rubber; the acid and alkali resistant, high temperature resistant large diameter silicone rubber tube is adopted. Ethylene propylene rubber, fluoro rubber or silicone rubber.

The name of the large-diameter silicone rubber tube There are many types of large-diameter silicone rubber tubes. The unified naming method is named after the material, structure and use. The products are all called: material + structure (process) + use + large diameter silicone rubber tube. For example: cotton woven oil resistant large diameter silicone rubber tube; steel wire wound pressure resistant large diameter silicone rubber tube.

Structures Large-diameter silicone rubber tube structures are generally classified into an inner rubber layer, an outer rubber layer, and a skeleton 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 large-diameter silicone rubber tube from the damage and erosion of the external environment; the skeleton layer is the bearing layer of the large-diameter silicone rubber tube, which imparts strength and rigidity to the tube body. . The working pressure of a large diameter silicone rubber tube depends on the material and structure of the skeleton layer.

大口径硅橡胶冷缩管的结构

用以输送气体、液体、浆状或粒状物料的一类管状橡胶制品。大口径硅橡胶管由内外胶层和骨架层组成，骨架层的材料可用棉纤维、各种合成纤维、碳纤维或石棉、钢丝等。一般大口径硅橡胶管的内外胶层材料采用天然橡胶、丁苯橡胶或顺丁橡胶；耐油大口径硅橡胶管采用氯丁橡胶、丁腈橡胶；耐酸碱，耐高温大口径硅橡胶管采用乙丙橡胶、氟橡胶或硅橡胶等。

大口径硅橡胶管的命名 大口径硅橡胶管的种类很多，统一命名的方法是材料、结构、用途的不同而命名，产品全称为：材料+结构（工艺）+用途+大口径硅橡胶管。例如：棉线编织耐油大口径硅橡胶管；钢丝缠绕耐压大口径硅橡胶管。

结构 大口径硅橡胶管结构通常分为：内胶层、外胶层和骨架层（或称中间层）。内胶层直接承受输送介质的磨损、侵蚀；外胶层保护大口径硅橡胶管内体不受外界环境的损伤和侵蚀；骨架层是大口径硅橡胶管的承压层，赋予管体强度和刚度。大口径硅橡胶管的工作压力取决于骨架层的材料和结构。
