Metal hoses are an important component of modern industrial equipment connection lines. Metal hoses are used for wire and cable, wire and cable protection tubes for automated instrumentation signals, and civil shower hoses, ranging from 3mm to 150mm. Small-diameter metal hoses (inner diameter 3mm-25mm) are mainly used for sensing line protection of precision optical scales and industrial sensor line protection.
The damage of the metal hose generally includes three cases of damage of the bellows, damage of the net sleeve and damage of the joint. The damage type of the different modes and the countermeasures are different.
1. The damaged joint of the joint is not only the connecting part of the bellows and the net sleeve, but also has the function of connecting the metal hose and other equipment, and is an important part to ensure the normal operation of the metal hose. The damage form of the joint mainly includes seal leakage and pitting perforation.
2, the damage of the net sleeve The outer protective surface of the metal hose is generally made of wire, soft and easy to deform. The design of the net sleeve can protect the metal hose externally. The damage forms mainly include the wear and tear of the metal ribbon, the wire breakage and the net drum kit.
3, the damage of the bellows In the three main components of the metal hose (corrugated pipe, mesh sleeve, joint), the common damage forms of the bellows are the main forms of wear and tear, corrosion leakage, weld cracking and blasting failure.
