Flange metal hose

A flanged metal hose is a flexible device used to connect pipelines, consisting of metal bellows, flanges, and other fittings. Here is a detailed introduction:

Structure and Composition

Metal bellows: It is the core component of flanged metal hoses, usually made of metal materials such as stainless steel and copper. It has good flexibility and stretchability, and can adapt to the displacement, vibration, thermal expansion and contraction of pipelines.

Flange: located at both ends of a metal hose, used to connect with pipelines or other equipment. Flanges usually adopt standard flange sizes and connection forms, such as plate flat welding flanges, neck welding flanges, etc., for easy installation and disassembly.

Other accessories: including seals, fasteners, etc. Seals are used to protect the sealing of flange connections and prevent medium leakage; Fasteners are used to firmly connect flanges to pipelines or equipment.

characteristic

Good flexibility: The special structure of metal corrugated pipes gives them high flexibility, allowing them to bend and expand freely within a certain range, effectively compensating for installation errors, thermal expansion and contraction, and displacement caused by equipment vibration.

Corrosion resistance (based on actual reports): The selected metal materials have good corrosion resistance (based on actual reports) and can adapt to various working media, such as acids, alkalis, salt solutions, and various chemical corrosive gases. They are suitable for harsh environments such as chemical, petroleum, and metallurgical industries.

High temperature resistance (based on actual reports) and high pressure: Metal hoses can withstand high temperatures and pressures, generally working in the temperature range of -200 ℃ to+800 ℃, and can withstand pressures of several megapascals or even higher, meeting the needs of various high-temperature and high-pressure pipeline systems.

Good sealing performance: The flange connection is matched with sealing components, which can confirm the sealing performance of the pipeline system, effectively prevent medium leakage, and protect the safe operation of the system.

Long service life: Metal hoses have high strength and fatigue resistance (based on actual reports), and can work stably for a long time under normal use conditions, reducing the frequency of maintenance and replacement and lowering the cost of use.

Application industry

Industrial pipeline system: widely used in pipeline systems of chemical, petroleum, metallurgical, power and other industrial industries, used to connect various equipment, pipelines and valves, compensate for thermal expansion, contraction, displacement and vibration of pipelines, and protect the safe operation of pipeline systems.

Building water supply and drainage system: In construction projects, it is used to connect water supply and drainage pipelines, air conditioning system pipelines, etc. It can effectively solve the displacement problems caused by building settlement, temperature changes, and other factors, and protect the sealing and stability of the pipeline system.

Mechanical equipment connection: It can be used to connect various mechanical equipment, such as pumps, compressors, fans, etc., to pipelines, absorb the vibration and displacement generated during equipment operation, reduce the impact on pipeline systems, and also facilitate equipment installation and maintenance.

Aerospace and Shipbuilding Industry: In the aerospace and shipbuilding industry, due to its good flexibility, corrosion resistance (based on actual reports), and high temperature resistance (based on actual reports) and high pressure performance, it is used in hydraulic systems, fuel systems, and various pipeline connections of aircraft and ships to meet the working requirements in special environments.

Selection and installation precautions

Selection: Select flange metal hoses of appropriate specifications and materials based on factors such as working pressure, temperature, medium, displacement, and installation space of the pipeline system. At the same time, it is necessary to consider parameters such as the diameter, length, and bending radius of the metal hose to confirm its compatibility with the pipeline system.

Installation: During installation, it is necessary to confirm that the flanges at both ends of the metal hose are correctly aligned with the flanges of the pipeline or equipment, and to use appropriate fasteners to tighten them evenly. Avoid excessive stretching, twisting, or squeezing of metal hoses during installation to avoid affecting their performance and service life. In pipeline systems, support and fixing devices should be reasonably installed to reduce the burden on metal hoses and protect their stability during operation. In addition, attention should be paid to the distance between the metal hose and surrounding objects to avoid damage caused by friction or collision.
