Introduction to the Performance of Stainless Steel Bellows

　Application range of bellows: Fluids—natural gas, manufactured gas, liquefied petroleum gas, air mixtures, biogas, and others. Pressure: Less than 0.1 MPa (typically for indoor low-pressure gas pipelines). Characteristics of bellows:

　　1. Meet users’ personalized needs by offering a variety of installation methods, such as wall embedding, concealed wiring, and surface mounting.

　　2. Durable and long-lasting. The pipes and pipe fittings are made of stainless steel SUS304 or SUS316L, and the pipes are equipped with protective sleeves to ensure a safe service life of over 70 years.

　　3. Equipped with compensation lines to prevent gas leaks caused by earthquakes, building settlement, and seasonal weather changes (records from the 1995 Kobe earthquake in Japan have already demonstrated the advantages of corrugated pipes in preventing earthquake-induced damage).

　　4. Easy to install, freely cuttable and bendable, with the same flow rate, allowing it to bend and pass through narrow spaces with ease.

　　5. After renovation, pipe laying can be carried out, allowing users to conveniently choose the timing for pipe installation.

6. Enhanced safety, optional lengths, and no joints in the middle of the pipe—thus reducing connection points and virtually eliminating gas leaks. Applicable media: gases such as natural gas, manufactured gas, liquefied petroleum gas, air mixtures, biogas, etc. Pressure: less than 0.1 MPa (typically for indoor low-pressure gas pipelines).

There are many types of bellows, including rubber bellows, bellows expansion joints, plastic bellows, stainless steel bellows, carbon steel cable tray bellows, and instrument bellows, among others. I’m not sure which one you’re asking about. A bellows expansion joint—also known as an expansion bellows or expansion compensator—is primarily used to ensure the safe operation of pipelines. Let me introduce you to the function of stainless steel bellows expansion joints: The working principle and function of stainless steel bellows expansion joints: The main elastic element of a stainless steel bellows expansion joint is a stainless steel bellows. It relies on the expansion and bending of the bellows to provide compensation in the axial, lateral, and angular directions of the pipeline. Its functions include:

　　1. Compensates for axial, lateral, and angular thermal deformations of the pipeline.

　　2. Absorb equipment vibrations and reduce the impact of equipment vibrations on pipelines.

　　3. Absorb pipeline deformation caused by earthquakes and settlement.

The main performance characteristics of PE corrugated pipes are as follows:

　　1. Unique structure, high strength, and resistant to compression and impact.

　　2. The inner wall is smooth, but the friction is high, resulting in excessive flow.

　　3. Easy to connect, with excellent seam sealing and no leakage.

　　4. Lightweight, quick to install, and low cost.

　　5. Has a buried service life exceeding 50 years.

　　6. Polyethylene is a hydrocarbon polymer that is resistant to acid and alkali corrosion.

　　7. The raw materials are environmentally friendly, non-toxic, non-corrosive, non-scaling, and recyclable.
