Type selection of sleeve type pipe joint and supporting use of plastic metal hose

Product characteristics: product material: (inner layer) is made of stainless steel hose or galvanized hose and special insulation treatment. (outer layer) adopts PVC raw material (anti ultraviolet and anti aging).
  

Of)
Product color: black, grey and other colors
Working temperature: -40 C ~+160 C
Product features: 1. The plastic hose has excellent waterproof, insulating and tensile properties.
2, the surface of the plastic hose is PVC, and the fire-retardant and flame retardant are added in the PVC plastic.
3, plastic hose package structure for a single button and interlock type, increase tensile strength, not easy broken or deformation.
4. The flexible plastic hose has good bending performance and smooth internal structure. It is easy to pass through the wire and cable.
5. The plastic hose is waterproof, oil proof, corrosion proof and good sealing.  Beautiful, compact, widely used in precision instrument and instrument wiring, electric power, wire, plastic, rubber and other industries of wire and electrical protection.
application area

Wiring protection for railways, locomotives, transportation systems engineering, air conditioners, all kinds of machinery, automation control equipment, power plants, chemical industry, transmission and distribution systems, communication systems, ships, buildings, and inside and outside parts.
Product use

The protection of wire and cable as well as insulation, waterproof, and improve the cable bending beauty.
Product parameters

The main parts of plastic coated metal hose made of austenitic stainless steel, so as to ensure the plastic coated metal hose excellent temperature resistance and corrosion resistance, temperature range of plastic package metal hose, -196-600 degrees C, in actual use, according to the pipe corrosion choose corresponding stainless steel grades, to ensure that the package the corrosion resistance of plastic metal hose.
Plastic coated metal hose use: the need for fully flexible pipeline, to prevent vibration at matching, used in steam, gas, air, oil, petroleum, chemical industry and so on can specific selection of reference hose material corrosion resistance and machine parameters of corrugated metal hose and plastic bag nominal diameter and pressure gauge, when in use please refer to the optimum length of plastic coated metal hose and the correct use of the installation method and the hose in the compensation of the settlement. Five elements of the type selection of plastic metal hose (stainless steel hose).
1. Nominal diameter of plastic metal hose, type and size of joint, length of plastic metal hose.
2, the pressure package plastic metal hose actual working pressure, the nominal pressure PN/ working pressure P.
3. The chemical properties of the medium in the medium coated metal hose, according to the corrosion resistance table, determine the material of each part of the plastic metal hose.
4. The working temperature and range of the medium in the plastic metal hose, and the ambient temperature when the metal hose is wrapped. At high temperature, the coefficient of temperature correction must be corrected to determine the maximum allowable pressure at working temperature in order to determine the correct selection of pressure grade.
5, according to the state of plastic coated metal hose was used, with plastic coated metal hose is properly installed. The minimum bending radius calculation and plastic coated metal hose factors such as plastic metal hose movement status and the length of bag, plastic bag length parameter correct selection of metal hose, and installed correctly. Plastic metal hose material: SUS301/SUS304; internal diameter 4mm-10mm polishing.
Usage method

The plastic metal hose is mainly used for the cable protection in the production and processing. When used, the cable wire is first penetrated into the tube, and then the DPJ type joint is fitted to the corresponding model.
