Product introduction

1, structure: Stainless steel hose is made of stainless steel (1Cr18Ni9Ti) bellows, mesh sleeve and joint (flange) combination or stainless steel bellows and joint (flange) combination.

2, function: The metal hose is in the pipe and pipe, pipe and equipment, equipment and equipment between the connection plays a compensation role. Its bending flexibility is used to make up for the position deviation caused by the installation of the pipeline system, and to bear the relative displacement required for the abnormal work of the two broken contacts.

3, use: widely used in metallurgy, petrochemical, shipbuilding, building materials, electricity, heat, gas and other industries.

4, Features: The product has the characteristics of light weight, small size, corrosion resistance, can be bent at will, strong bearing capacity and so on.

5, specification model: nominal outer diameter: 8-300 (mm) Wall thickness: 2-3 (mm) Temperature range: -196°C-420°C.

This section describes three common metal hoses

Flange connection metal hose: one end is flat welded flange, the other end is a loose flange, the flange material is carbon steel, is made of thin wall seamless or welded stainless steel pipe through high-precision plastic processing.

Spherical (inner cone) joint metal hose: Metal hose is made of thin-walled seamless or multi-welded stainless steel pipe through high precision plastic machining. Due to the elastic characteristics of the bellows profile, the hose has good flexibility, so that it is easy to absorb a variety of circulating loads of motion and deformation, especially in the pipeline system has the ability to compensate for large displacement.

Pump connection hose: The installation of a pump connection hose at the inlet and outlet of the pump can reduce the vibration and noise of the pipe system, but also compensate for a certain displacement, protect the normal work of the system and stabilize the working environment.

Installation precautions

1, in the selection of metal hose, in order to facilitate the installation, please choose one end of the loose sleeve flange of the metal hose.

2, the construction site should protect the surface of the metal hose during the welding operation to prevent welding slag and arc burning of the metal hose.

3, it is strictly prohibited to twist the metal hose installation.

4, should not bend along the metal hose root, there should be no dead bend.

5, the medium shall not be corrosive to the bellows material, and the chloride ion content in the medium should be less than 25PPM.

6. Strictly install the installation diagram and install the correct installation method. (See installation guide)

7. Mechanical damage to the flange sealing surface is strictly prohibited.

8, can not use chlorine-containing detergent live wire brush metal hose inside the dirt.

Stainless steel metal hose applications

Stainless steel pressure resistant metal hose made of austenitic stainless steel material or according to user requirements of the material, with excellent softness, corrosion resistance, high temperature resistance (-235℃ ~ +500℃), high pressure resistance (higher 32MPa), in the pipeline can be connected in any direction, It is used for temperature compensation and absorption of vibration, reduce noise, change the direction of medium transmission, mechanical displacement between pipelines or between pipelines and equipment, etc., and double flanged metal corrugated hoses are especially suitable for flexible joints of various pumps and valves with displacement and vibration.
