Pipeline installation stress In a complex pipeline system, due to the limitation of spatial location conditions, various difficulties in installation work often occur: it is impossible to install the formed pipeline; bending, arriving and making do with the installed pipeline will inevitably produce local cold correction. According to the pipe diameter and the specific situation of the site, the cold correction amount ranges from a few millimeters to tens of millimeters, and some are hundreds of millimeters.

1. why the use of metal hose:

Pipeline installation stress In a complex pipeline system, due to the limitation of spatial location conditions, various difficulties in installation work often occur: it is impossible to install the formed pipeline; bending, arriving and making do with the installed pipeline will inevitably produce local cold correction. According to the pipe diameter and the specific situation of the site, the cold correction amount ranges from a few millimeters to tens of millimeters, and some are hundreds of millimeters.

Practice has proved that the greater the amount, the higher the internal stress. These residual installation stresses in the piping system are undoubtedly huge hidden information. The lubricating oil duct of a certain section of the bearing of a certain type of engine was broken many times in actual operation, which was caused by excessive installation stress.

Because it can be bent at will, the internal stress generated by bending under the rated bending radius is very small, which can bring great convenience to the installation work and also play a certain role in the operation of the pipeline system. This is why some piping systems must use metal hoses. Compensation pipe position Due to the need to load and unload the mold, the movable cylinder on the vulcanizer will move up and down. The copper serpentine tube will fatigue fracture after repeated reciprocating motion. Although it can still be used after repair, stopping the repair will cause time loss.

Although the hose has good flexibility and strong anti-fatigue ability, it is a weak link in terms of pressure, temperature resistance, and anti-aging, and it cannot be used after a few months. The good comprehensive performance of Xi'an metal hose is fully reflected here.

. In the general industrial field, in addition to pressure and temperature, there are often some harsh conditions, such as fatigue, corrosion, vibration, compression, shock, etc. In this case, the position shift of the compensation pipe is. Appropriate. It can absorb vibration, which can not only improve the fatigue failure ability of the system, but also reduce noise. This is why metal hoses are used in some piping systems.

Principle and structure of 2. metal hose:

Metal hoses are generally composed of corrugated pipes, mesh sleeves and joints. The main body of the corrugated pipe yes metal hose plays a flexible role; the net cover plays a role of strengthening and shielding; the joint is used as a connection. For different application requirements, their connection methods are also different: the corrugated pipe, the net sleeve and the joint are connected by welding, which is called welding; the connection in the form of mechanical clamping is called mechanical clamping. In addition, the combination of the above two methods is called mixing.

Metal hose products include oil suction hose, steam hose, sand blasting hose, acid and alkali suction hose, food hose, oxygen blowing hose and various shaped hose. Widely used in machinery, chemical, petroleum, metallurgy, food and other industries. Pressure-resistant metal hose, what is the pressure range? The pressure range of the hose is generally PN 0.6-32.0 MPa. Up to 42.0 MPa..

The metal hose that Baoding Metal Hose Company made up to share with you is the main pressure-bearing part of the hose installed in the pressure pipe, and it is also the sheath of the corrugated pipe. According to the pressure in the pipeline and the application place, one or more layers of stainless steel wire or steel belt can be selected.

Focus on hot spots

Congratulations on the official launch of our company's website

There are perfect quality testing equipment and a sound quality assurance system, testing raw materials, semi-finished products and finished products, and testing the assembly hose one by one, which is a reliable guarantee for product quality.

What are the applicable scenarios of low pressure hose?

Low pressure hose is suitable for many scenarios, including industrial production, building construction, agricultural irrigation and household use. In industrial production, low pressure hose is often used in the process of conveying gas or liquid, such as conveying air, water, oil and so on. They are usually used in the supply and water supply system of mechanical equipment, the fluid conveying system of the factory production line, and the cooling system.

Low pressure hose change how to choose?

When choosing a low pressure hose, the first thing to consider is the material of the hose. Common hose materials are polyvinyl chloride (PVC), rubber and polyurethane. PVC hose has good chemical resistance and strength, suitable for general low pressure occasions. Rubber hose has good wear resistance and oil resistance, suitable for some special working environment. Polyurethane hose has excellent wear resistance and tear resistance, suitable for highly worn working environment.

The difference between low pressure hose and metal hose

The low-pressure hose is mainly made of rubber material, which has good softness and elasticity. Its interior is hollow and can be used to transport liquids or gases. In contrast, metal hoses are made of metal materials, such as stainless steel, which have higher strength and pressure resistance.

Wire Braided Hose Engineering Case

The company has successively developed and produced various specifications of medium and low pressure hoses, special hoses, stainless steel metal hoses, steel tubing assemblies for construction machinery, conveyor belts and seals, and more than 20 varieties of products, which are sold throughout the country and exported to some foreign regions, are widely used in machinery and equipment supporting, petroleum, coal mining, metallurgy, chemical industry, transportation and other industries, and are well received by users.
