Metal Hose L=200/250/300 Pressure 1.6/2.5mpa 304 Material Flanged Butterfly Valve

Introduction

Metal hose is an important component in the connecting pipeline of modern industrial equipment. Metal hose is used as wire, cable, wire and cable protection pipe of automatic instrument signal and civil shower hose, with specifications ranging from 3mm to 150mm. It is mainly used for the protection of small diameter (3mm-25mm) metal sensing lines.

Use attention

1. The corrugated pipe of metal hose is made of chromium nickel austenitic stainless steel. Pay attention to prevent the pitting corrosion of nitrogen ions and the corrosive damage of dilute sulfuric acid.

2. After the user conducts the hydrostatic test on the equipment and pipe system equipped with metal hose, it shall prevent the impact of rust block and the deposition of chloride ion containing sediment, resulting in corrosion and mechanical damage.

3. During installation, the metal hose shall be protected from scalding and mechanical damage caused by spatter during welding, otherwise it will cause leakage.

4. The sealing pipe system shall strictly comply with the safety operation regulations to prevent the hose from pulling off or bursting due to overpressure caused by improper operation or other factors.

5. Please carefully digest the example of metal hose installation method, and install and use it in strict accordance with the correct sketch.
