What are the specifications and models of metal hoses?
Metal hoses are suitable for conveying liquids and all high-temperature media. Specification DN20-DN800mm can be selected according to equipment and pipeline diameter. The specifications of stainless steel hoses mainly include single-button P3 and double-button P4, and the caliber of metal hoses generally ranges from 5mm to 100 mm, and the models are compiled according to the requirements of various manufacturers. The general coding rule of metal hose is enterprise name code+hose inner diameter+hose outer diameter+single or double buckle code. For example, TF0406D represents a single-button metal hose with an inner diameter of 4mm and an outer diameter of 6mm produced by Tongfeng metal hose.
Metal hose is an important connecting part in engineering technology, which consists of corrugated hose, net sleeve and joint. It is used as compensation element, sealing element, connecting element and damping element in various gas transmission and infusion pipeline systems and compensation systems for length, temperature, position and angle, and is applied to aerospace, petrochemical industry, mining electronics, mechanical shipbuilding, medical and health care, textile electronics, energy construction and other fields.
Structural characteristics of metal hose
1. The whole metal hose is made of 1Cr 18Ni9Ti stainless steel, which has strong corrosion resistance.
2. The hose body is a hydroformed thin-walled stainless steel body, which has strong flexibility, flexibility, bending resistance and vibration resistance, and the reinforced protection of the woven net sleeve makes it have higher bearing capacity.
3. Besides the standard of thread and flange, the connection at both ends of the hose can also be made into other connection modes, which is convenient for connection and use.
4. This product is not only suitable for matching with rotary joints, but also widely used for flexible connection of conveying various fluid media.
The popular metal hose only uses one layer of net sleeve; Where it is not commonly used, two or three layers should be woven.
1, flexible between metal hose pitches;
2, the metal hose has good flexibility, no blockage and good rigidity;
3. The metal hose has light weight and good caliber consistency;
4. The metal hose has good flexibility, repeated bending and flexibility;
5. The metal hose has good corrosion resistance and high temperature resistance;
6. The metal hose is resistant to rat bite and abrasion, and the internal wires are prevented from abrasion;
7. Metal hose has strong bending, tensile and lateral pressure resistance;
8. The metal hose is soft and smooth, easy to thread, install and locate;
9.PVC metal hose has good waterproof performance.
Conclusion: Through the above introduction, I believe everyone has a certain understanding of various types and models of metal hoses and the structural characteristics of metal hoses. Metal hose is a very important connector, which has a strong protective effect on circuits, wires, cables and pipelines. Because it is made of metal rings, it is very flexible. I hope that through the above introduction, we can help you understand the various types and models of metal hoses and the structural characteristics of metal hoses.
