Vacuum Bellows Hose
Connection Method of Stainless Steel Bellows Hose
Stainless steel corrugated pipes usually use 304 stainless steel or 316 stainless steel as raw materials. They have good softness, corrosion resistance, high temperature resistance, wear resistance, tensile resistance, water resistance, and can provide a certain shielding effect.
Stainless steel metal hose is mainly composed of bellows, mesh sleeve and joint. The corrugated pipe is the body of the metal hose, which plays the role of flexibility; the net sleeve plays the role of strengthening and shielding; the joint plays the role of connection. Different stainless steel hoses have different connection methods during use. Some are connected by welding, some are mechanically clamped, and some are mixed. The three parts of the bellows, mesh sleeve and joint are connected by welding, called welding; mechanically clamped, called mechanical clamping; In addition, there is a combination of the two methods, called hybrid. In practice, the user needs to choose which way to connect according to actual requirements.
The use of stainless steel corrugated hoses: mainly used to protect precision optical rulers, protection of sensor lines and electrical wiring of automatic instrument signals.
Types of stainless steel metal bellows: mainly divided into two types, one is a spiral bellows; the other is a ring bellows. However, whether it is a spiral or ring-shaped corrugated hose, it is a flexible pressure-resistant pipe fitting. It is usually installed in a liquid conveying system to compensate for the mutual displacement of the connecting end of a pipeline or a machine or equipment. , Muffling and other functions, with good flexibility, light weight, corrosion resistance, fatigue resistance, high and low temperature resistance and other characteristics.
The so-called spiral corrugated tube refers to a tube-shaped shell in which the corrugations are spirally arranged. There is a spiral rising angle between two adjacent corrugations, and all corrugations can be connected by a spiral line.
The so-called ring-shaped corrugated tube refers to a tube-shaped shell with a corrugated closed ring shape. The waves and waves are formed by a series of circular corrugations. The annular corrugated pipe is formed by seamless pipe or welded pipe. Restricted by the processing method, the length of a single tube is usually shorter than that of a spiral bellows. The advantages of annular bellows are good elasticity and low stiffness.
