The difference between metal flexible joints, rubber flexible joints, and metal hoses

Author:


Metal flexible joint
Metal flexible joints, as flexible pressure fittings installed in liquid conveying systems, are used to compensate for the mutual displacement of pipelines, machines, and equipment connection ends, absorb vibration energy, and can play a role in vibration reduction, noise reduction, etc. They have many advantages such as good flexibility, light weight, corrosion resistance, fatigue resistance, and high and low temperature resistance.
The connection between metal soft joints and pipelines can be divided into flange connection, welding, screw thread connection, and quick joint connection. Small diameter metal soft joints generally use screw thread and quick joint connection, while larger diameters generally use flange connection and welding connection. The connection methods of rubber soft joints generally include threaded connection, flange connection, clamp connection, and so on. It reduces vibration, reduces noise, has good scalability, and is easy to use. High internal density, able to withstand high pressure, and has good elastic deformation effect. Reduced vibration, reduced noise, good scalability, and easy to use.

Rubber flexible joint
Rubber soft joints have good vibration isolation and noise reduction effects. Installing a certain length of metal soft joints at the inlet and outlet of equipment such as pumps and compressors can reduce vibration and noise, improve engineering quality and service life. However, rubber soft joints do not have an advantage in temperature, while metal soft joints can increase both temperature and pressure significantly. Metal soft joints have high flexibility, large deflection, pressure resistance, and can be set in length at will.

It reduces vibration, reduces noise, has good scalability, and is easy to use. High internal density, able to withstand high pressure, and has good elastic deformation effect. Reduced vibration, reduced noise, good scalability, and easy to use. The rubber materials used vary depending on the medium, including natural rubber, styrene butadiene rubber, butyl rubber, nitrile rubber, EPDM rubber, chloroprene rubber, silicone rubber, fluorine rubber, and so on. They have functions such as heat resistance, acid resistance, alkali resistance, corrosion resistance, wear resistance, and oil resistance.
Metal hose
Metal hoses are metal corrugated pipes that have sealing properties, and metal mesh pipes are woven with metal wires. There are two types of corrugated pipes used in metal hoses, one is a spiral corrugated pipe; The other type is a circular corrugated pipe.
Metal hose is an important connecting component in engineering technology, which is composed of corrugated flexible pipe, mesh sleeve and joint. In 1993, China issued the national standard General technology Conditions for Corrugated Metal Hose (GB/T14525-93). The metal hose is made of austenitic stainless steel material or materials according to user requirements, which has excellent flexibility, corrosion resistance, high temperature resistance (-235 ℃~+450 ℃), and high pressure resistance (up to 32MPa). It can be connected in any direction in the pipeline to compensate for temperature and absorb vibration, reduce noise, change the direction of medium transportation, eliminate mechanical displacement between pipelines or between pipelines and equipment, etc, Double flange metal corrugated hose is particularly suitable for flexible joints of various pumps, valves, etc. with displacement and vibration.
Metal soft joints and rubber soft joints are both soft joints literally, and most people think they are very similar. However, the fact is that the two functions are very different. First, it can be distinguished from the name that rubber soft joints are rubber and metal soft joints are metal. Metal soft joints and rubber soft joints have a wide range of applications, usually used for the connection of pumps, valves, fire equipment, pipelines with high vibrations, and pipeline systems with frequent changes in temperature and cold. Let's take a look at the difference between metal soft joints and rubber soft joints.
Different pipeline working conditions require different soft connections to be selected. Equipment such as pumps and compressors used in engineering can generate vibration and noise during operation, posing a threat to engineering quality and human health.
Rubber soft joints have good vibration isolation and noise reduction effects. Installing a certain length of metal soft joints at the inlet and outlet of equipment such as pumps and compressors can reduce vibration and noise, improve engineering quality and service life.
However, rubber soft joints do not have an advantage in temperature, while metal soft joints can increase both temperature and pressure significantly. Metal soft joints have high flexibility, large deflection, pressure resistance, and can be set in length at will.
