Stainless steel gas hose 2 layers with male fittings

The stainless steel gas hose includes a hose joint. The hose joint is composed of a hose body and a steel sleeve fastened to one end of the hose body. , the axial depth of the annular coupling groove is greater than the length of the steel sleeve, a part of the inner surface of the annular coupling groove is a conical surface, and the inner end of the conical surface is formed with another part of the inner surface of the annular coupling groove adjacent to the inner surface. steps. The structure avoids the phenomenon that when the hose joint is matched with the hose, the hose is inserted too deeply into the hose joint, which causes deformation of the end of the hose joint, which is beneficial to the smooth flow of gas and has high safety. An arc transition is adopted at the junction between the outer surface and the inner surface of the annular joint groove to prevent stress concentration.

Stainless steel gas hose is a kind of flexible hose involved in the transportation of natural gas, coal gas or liquefied petroleum gas. Made of convex and concave phase structure. The stainless steel gas hose has a smooth surface, is easy to clean, and has good flexibility of the hose body; the strength of the hose is further improved, the service life is extended, the product quality is improved, the aging is delayed, and the color is prevented.
