The use of shower hose in home decoration is very common. Hose installation belongs to the hidden part. Generally speaking, the quality is not good or bad, and the problems in actual use are generally not very clear. Therefore, when buying hoses, we must choose high-quality hoses. Metal hoses are a kind of material that people use more now. Now let’s introduce the metal hose.
1. Thread the metal hose
Due to the different styles, functions, materials and specifications of metal hoses in the current market, the price of metal hoses is also very different. The threading metal hose is made of 304 stainless steel or 301 stainless steel. It is used as the wire and cable protection pipe for cables, wires and automatic instrument signals. The specification is from 3mm to 150mm. The inner diameter of ultra-small diameter metal hose is 3mm-25mm. It is mainly used for industrial sensor line protection and sensing line protection of precision optical ruler. It has good flexibility, high temperature resistance, wear resistance, corrosion resistance and tensile resistance.
2. Corrugated hose
Corrugated metal hose is a kind of flexible pipe in modern industrial pipeline, which is mainly composed of mesh sleeve, joint, corrugated pipe and so on. The inner pipe is a thin-walled stainless steel bellows with spiral or annular waveform, and the outer mesh sleeve of the bellows is woven with stainless steel wire or steel strip according to certain parameters. In terms of structure, corrugated metal hose has two price trends of strip and pipe, forming annular corrugated pipe and spiral corrugated pipe. It is a high-quality flexible pipe in the field of modern industry.
3. Plastic coated hose
I believe most people don’t know much about this problem. The inner layer of plastic coated metal hose adopts stainless steel shower hose and galvanized hose for special insulation treatment. Plastic coated hose has the advantages of waterproof, insulation and tensile strength. The surface is made of PVC material and added with fire retardant. At the same time, the plastic coated hose structure is single button and double button, which greatly increases the tensile strength and is not easy to break and deform.
Let’s introduce some tips for purchasing metal hoses.
1. See the size: nominal diameter of hose, joint type (mainly flange connection, threaded connection and quick connector connection), size of metal hose and hose length.
2. Look at the pressure: according to the actual working pressure of the hose, query the nominal diameter and pressure gauge of the corrugated metal shower hose to decide whether to use the metal hose of stainless steel mesh sleeve type.
3. Quality: the chemical property of the medium conveyed in the hose determines the material of each part of the hose according to the corrosion resistance of the hose material.
4. Temperature: the working temperature and range of the medium in the hose; Ambient temperature at which the hose is operating. In case of high temperature, the pressure after temperature correction shall be determined according to the working pressure and temperature correction coefficient of metal shower hose under high temperature, so as to determine the correct pressure grade.
5. Look at the status: according to the status of the shower hose in use, refer to the correct use and installation method of metal hose and the length of hose in settlement compensation The length calculation of various motion states of the hose, the bending times and bending radius of the hose and other factors, and the parameters shall correctly select the hose length and install it correctly.
