What is the difference between metal conduit and Flexible Metal Conduit?

Dec. 20, 2019

Metal conduit is generally a metal conduit, which can transmit liquid and withstand a certain pressure. Flexible Metal Conduit is a metal spiral sleeve, which is generally used as a wire protection sleeve. The Electrical Flexible Conduit Factory will explain the differences between them in detail.

1, different definitions

Metal hose: Metal hose is an important component in the connecting pipeline of modern industrial equipment. Metal hoses are used for wires, cables, wire and cable protection tubes for automation instrument signals, and civilian shower hoses with specifications from 3mm to 150mm. Small-caliber metal hoses (inner diameter 3mm-25mm) are mainly used for the protection of sensor lines and industrial sensor lines of precision optical rulers.

Flexible metal casing: Flexible (metal) wire protection casing (now known as flexible metal conduit), the basic type of KZ material is a special insulating resin layer on the inner wall made of hot-dip galvanized steel tape on the outer layer. The basic type is covered with plastic soft polyvinyl chloride, and the flame-retardant KVZ is covered with soft flame-retardant polyvinyl chloride on the basic type.

Ultra-small-diameter metal wire protection sleeve (inner diameter 3mm-25mm) is mainly used for the protection of precision optical ruler's sensor circuit and industrial sensor circuit protection. It has good softness, corrosion resistance, high temperature resistance, wear resistance and tensile strength. Sex.

2, different applications

Metal hose: used to protect various equipment signal lines, transmission wires and cables, and fiber optic cables. Armored optical cables, precision optical rulers, optical measuring instruments, medical instruments, wire protection tubes for machinery and equipment; applicable to public telephones, remote water meters, door magnetic alarms, and other equipment that requires safety protection of wires;

Protection tubes for various small wires; protection tubes for various computer, robots, etc. network cables. PVC protective film for solar equipment.

Flexible metal casing: used as wire, cable, and wire protection cable for automatic instrument signals, specifications from 3mm to 130mm.

Electrical Flexible Conduit, standard pipe is rolled from double-layer materials of galvanized steel strip, steel strip and electrical paper, and there are also polyvinyl chloride made for outdoor, high temperature, cold and clean or corrosive gas environments Covering, aluminum belt covering, stainless steel belt covering sleeve. Flexible metal casing has excellent corrosion resistance, good vibration resistance, light weight (only about 1/4 of the weight of steel pipe), unlimited length, can be cut freely according to the needs of the project, and can be embedded in the steel mesh. The outer surface of the tube is thread-like, and can be connected and bent with corresponding accessories. It is mainly used for concrete buried and outdoor low-voltage electrical wiring protection. It can also replace traditional metal hoses as wire protection pipes between steel pipes and electrical equipment.
