Bellows specification

Corrugated pipe is a flexible pipe made of metal material, which is characterized by high elasticity and corrosion resistance. Bellows are mainly used to transport liquids, gases, solid particles and other substances. They have high bearing capacity and bending resistance, and are widely used in industry, architecture, aerospace and other fields.

Dimensions and specifications of bellows

The size of bellows is usually determined according to its inner diameter, outer diameter and length. The common internal diameter specifications of bellows are DN6, DN8, DN 10, DN 12, DN 15, DN20, DN25, DN32, DN40, DN50, etc. The external diameter specification is determined according to the internal diameter specification and wall thickness of corrugated pipe, which is generally DN 10-500mm. The length specification of bellows is also flexible and can be customized according to user's needs.

Bellows material

Bellows are mainly made of stainless steel, copper, aluminum, titanium, iron, chromium, nickel and other metal materials, of which stainless steel bellows is the most commonly used one. Stainless steel corrugated pipe has good corrosion resistance, high strength and high temperature resistance, and is suitable for conveying various liquids, gases and solid particles.

Use of bellows

Bellows are widely used in various industrial fields, such as petroleum, chemical industry, medicine, food, paper, textile, aerospace and so on. Its main uses include the following aspects:

1. Transmission of liquid and gas: Bellows can be used to transmit various liquids and gases, such as water, oil, gas and steam.

2. Conveying solid particles: Corrugated pipes can also be used to convey various solid particles, such as pulverized coal, cement and slag.

3. Seismic noise reduction: Corrugated pipes have good seismic performance and noise reduction effect, and can be used in buildings, bridges and other projects.

4. Connecting pipes: Corrugated pipes can be used to connect various pipes and equipment, with good sealing performance and bending performance.

Operating steps of bellows

The operation steps of bellows are relatively simple, mainly including the following aspects:

1. installation: connect the corrugated pipe to the equipment or pipeline, and pay attention to the sealing performance and bearing capacity of the joint.

2. Usage: conveying liquid, gas or solid particles as required, and paying attention to the bearing capacity and bending performance of corrugated pipe.

3. Maintenance: Check and maintain bellows regularly, such as cleaning and replacing damaged parts.
