Metal Stainless Steel F316 Flange Joint Flexible Braided Ss Expansion Bellow Hose Metal Hose
Metal bellows is a high-quality flexible connecting pipe in modern industrial pipelines. It is mainly composed of metal bellows, metal mesh body and various types of joints. Its inner tube is a thin-walled stainless steel corrugated tube with spiral corrugation or ring corrugation, and the outer mesh sleeve of the corrugated tube is woven by stainless steel wire or stainless steel strip according to certain parameters. The joints at both ends of the hose are prepared according to the joint form of the user's pipeline or equipment.
Types of bellows: bellows are mainly divided into metal (stainless steel, carbon steel) bellows and plastic bellows. Metal bellows are mainly used to compensate pipeline thermal deformation, shock absorption, and absorb pipeline settlement deformation. It is widely used in petrochemical, metallurgical and other industries. Corrugated pipes of other materials such as plastics play an irreplaceable role in the fields of medium transmission, power threading, machine tools, and home appliances. Metal bellows are used for pipes with thermal expansion and contraction.
Introduction to the advantages of stainless steel corrugated hose
1. Good workability: The stainless steel corrugated hose is a thin-walled hose, the overall weight is reduced, which greatly reduces the load and construction time of construction work.
2. Corrosion resistance: The main body of the bellows is made of 304 or 316L stainless steel, with stainless steel joints or carbon steel joints at both ends, which has good corrosion resistance. To ensure tightness.
3. High pressure resistance: Considering many factors such as the actual working pressure of the bellows, use environment and use conditions, all parameters have been carefully calculated and repeatedly tested to ensure its pressure safety in work.
4. Many types: the existing bellows diameter range: DN8-DN4000, others are customized according to customer requirements.
5. Anti-vibration and anti-dislocation: The stainless steel corrugated hose has the characteristics of good flexibility and displacement compensation.
6. Beautiful appearance: The appearance is clear and bright, and it is as bright as new forever.
7. Vibration resistance and high speed
8. It can transmit torque by itself. In the operation of ordinary mechanical seals, a transmission seal structure must be added
9. Less leakage points.
