Braided Metal Hose
Braided metal hose is a high quality flexible pipe in modern industry pipelines. Braided metal hose is installed in liquid delivery systems as a flexible pressure resistant pipe fitting, used to compensate pipeline or equipment connection displacement, also used to absorb vibration energy, plays function of vibration and noise reduction. Braided metal hose owns advantages of good flexibility, corrosion resistant, anti-fatigue, high and low temperature resistant, noise and vibration reductive, strong leakproofness and long service life, it has been widely used to deliver steam, water, oil, medicine and all kinds of industrial gas. Braided metal hose is composed of bellows, braided mesh and joints, the inner pipe is spiral or annular thin-wall stainless steel bellows, braided mesh is weaved by stainless steel wire or steel belt according to certain parameter. Braided metal hose’s connecting joints or flange should match with pipeline’s joints or flange. Metal hose’s corrugated pipeline is made by thin-walled seamless or stainless steel pipe, which has been high precision plastic processed. The elastic characteristic of bellows giving metal hose excellent flexibility and fatigue resistance, which makes it easy to absorb cyclic loading of all kinds of motion deformation, especially capable in compensating large displacement in pipeline system, so as to make sure the safety and stable operation of pipeline systems. In order to promote the compressive strength of metal hose, manufacturer always add wire mesh outside the metal hose, some even reach to two or three layers. Since metal hose is made by tin-walled pipe through pressing into corrugations, it has small axial rigidity, to enhance its bearing capacity and protect metal hose from being damaged, thus, generally we use braided metal wire to cover in outside. Of course, beauty appearance needs us to pay attention to, but enhancing braiding quality and ensure metal hose usability is more important.
- Installation stress of pipeline.
In complex pipeline system, installation always been restricted by space and location, cold straightening value is commonly seen. Based on different pipeline diameter and spot condition, the cold straightening value differs from several millimeters to dozens of millimeters, even hundreds of millimeters. The larger of the cold straightening value, the higher of the internal stress, internal stress is a hidden danger to the pipeline system. Since braided metal hose is able to bend freely and generate minimize internal stress in rated bending radius, thus, it is extremely convenient for installation, that’s the reason why metal hose is the essential pipe fitting for some pipeline systems.
- Compensate pipeline location.
Although rubber hose has excellent flexibility and fatigue resistance property, it has weakness in pressure bearing, temperature resistance and aging resistance, usually has short service life. Metal hose has excellent overall performance, in general industry, metal hose is the best choice for compensating pipeline displacement.
- Vibration absorption.
Braided metal hose can not only promote the fatigue fracture ability, but also reduce noise.
- Braided metal hose is made from 1Cr18Ni9Ti stainless steel material, owns strong corrosion resistant performance.
- Metal hose is hydro formed by thin walled stainless steel pipe, it has strong flexibility, elasticity, shock resistance property, braiding protection giving the metal hose higher pressure bearing ability.
- For connecting method, except for threaded connection and flange connection, other connection methods is acceptable.
- Braided metal hose can not only math with rotating joints, it has been widely applied in various fluid medium delivery.
- Braided metal hose is corrosion resistant, high temperature resistant, low temperature resistant (-196℃~+420℃), light weight, small volume and has good flexibility.
According to different connection method, metal hose can be divided into: flange type, thread type, quick coupling type and welding type.
- Flange type: for metal hose whose diameter is above 25mm, in condition of bearing general working pressure, flange type is the main type. Its sealing model is matching with mortise. It has good sealing performance, but high processing difficulty, sealing face is easy to injured.
- Thread type: for metal hose whose diameter is below 50mm, in condition of bearing higher working pressure, thread is the best choice. When screw down the thread, the inner and outer taper face fit closely, in this way to achieve sealing. Generally taper angle is 60 degree, also has 74 degree. Although thread type has better sealing property, when installation, it must maintain the concentricity of butt joints.
- Quick type: for metal hose whose diameter is below 100mm, suitable for place where need quick dispatch. It use O sealing ring to seal which is made by fluoroplastic or special rubber. It is especially suitable for environment such as fire ground and battlefield. You only need several seconds to separate or butt joint a set of joints.
