General metal hose introduction
What is the difference between a universal metal hose and a normal metal hose? The universal metal hose is an important connecting member in engineering technology, and is composed of a stainless steel corrugated flexible tube outer wrap woven mesh sleeve and two end joints. The advantages of the universal metal hose are: easy and quick to install, one model can be used in a variety of fields, widely used, and versatile.
Universal metal hoses are used in a variety of gas and infusion piping systems and as compensating, sealing, connecting and damping components in compensating systems. They can be used for length, temperature, position and angle of any factor. Position compensation has been applied in aerospace, petrochemical, mining electronics, mechanical shipbuilding, medical and health, textile electronics, energy construction and other fields.
Bellows used in general purpose metal hoses include both spiral and toroidal.General metal hose installation and use1. National Standard "General Technical Conditions for Corrugated Metal Hose" (GB/T14525-93)

2. The bellows of the metal hose is made of chrome-nickel austenitic stainless steel. When using it, take care to prevent pitting corrosion of nitrogen ions and corrosive damage of dilute sulfuric acid and dilute sulfuric acid.
3. After the user conducts the water pressure test on the equipment and piping with metal hoses, it should prevent the impact of rust block and chloride ion sediment, causing corrosion and mechanical damage.
4. The metal hose should be protected from spatter and mechanical damage during welding, otherwise it will cause leakage.
5. The sealed piping system shall strictly abide by the safe operating procedures to prevent the hose from being pulled off or blasted due to overpressure caused by improper operation or other factors.
6. Please carefully digest the metal hose installation method and install it in strict accordance with the correct sketch.
