Flexible metal conduit refers to PULLKA wire maintenance conduit, which is a standard type conduit made of galvanized steel strip, steel strip, and electrical paper double-layer data roll. In addition, there are PVC coating, aluminum strip coating, and stainless steel strip coating conduits specially designed for outdoor, high temperature, high cold, and clean or corrosive gas environments.



Flexible metal sleeves have superior corrosion resistance, good shock resistance, light weight (only about 14 times the weight of steel pipes), unrestricted length, can be cut freely according to engineering needs, and can be embedded in steel mesh. The outer surface of the pipe is threaded and can be connected and bent with corresponding accessories. Primarily used for concrete embedding and outdoor low-voltage electrical wiring maintenance, it can also replace traditional metal hoses as wire maintenance pipes between steel pipes and electrical equipment.

Metal hose: The metal hose used in electrical engineering refers to a filler free metal hose made of galvanized low-carbon steel strip (which has been coated with plastic in recent years). It can be divided into single and double buckles in structure, commonly known as snake skin hose, such as the common P3 type galvanized metal hose.

Metal hoses are generally used at the junction of electrical equipment, motor junction boxes, and cable maintenance steel pipe ends to maintain wires or cables from mechanical damage; It is also commonly used as a connecting maintenance pipe when exposed piping passes through elastic (settlement) joints. The quota is separated by its inner diameter and listed in terms of each length.
