Bellows, though seemingly simple, play an irreplaceable role in fluid systems and pressure measurement fields. Their unique corrugated shape not only provides excellent sealing and flexibility but also offers multiple protections in the operation of industrial equipment. As a company specializing in bellows production, Tianjin Donghao Hose Co., Ltd. (DonghaoFlex) is dedicated to providing customers with high-quality bellow products. Below, we’ll detail the types of bellows, functional features, and application scenarios based on our practical application cases and customer feedback.

Bellows Classification and Features: Choosing the Right Fit for Your Application

We know that different structures of bellows suit different environments. Here are some common types of bellows, along with their features and applicable scenarios.

• U-Type Bellows: Known as the "all-rounder," suitable for displacement compensation in various pressure environments. U-type bellows are highly elastic and versatile. According to feedback from an automotive parts client, Donghao's U-type bellows performed excellently in the vibration environment of the engine compartment, ensuring long-term equipment stability.

• C-Type Bellows: C-type bellows are more specialized, commonly used in certain mechanical structures. Recently, our C-type bellows have been widely applied by a machinery manufacturer in specialized equipment, with clients noting its outstanding performance under high-intensity pressure.

• S-Type Bellows: For projects requiring significant displacement, S-type bellows are ideal. With strong flexibility and adaptability, one Donghao client in the railway industry noted its capacity to adapt to displacement changes caused by track vibrations after installation.

• V-Type Bellows: Designed specifically for high-pressure environments, V-type bellows have strong pressure resistance and are suitable for high-pressure fluid systems. In petrochemical fields, our V-type bellows help clients achieve higher sealing and durability, especially for high-pressure system safety.

• Ω-Type Bellows: With unique characteristics, these bellows are particularly suited for high-precision fluid transmission applications. Multiple semiconductor equipment manufacturers choose Donghao's Ω-type bellows for gas transmission, with clients praising its high precision and stability, providing effective support for production safety and consistency.

Multiple Functions of Bellows: Flexibility, Sealing, and Precise Sensing

Bellows not only vary in type, but their design also enables multiple functions across different scenarios. Here are the main functions of bellows, combined with our application cases, to help you better understand how to select the appropriate product.

• Sealing Function: Precisely designed, bellows prevent fluid leakage, making them ideal for high-pressure, high-sealing applications. In aerospace applications, a client noted that Donghao’s bellows enhance the safety of fluid transmission due to their excellent sealing properties.

• Displacement Compensation: Bellows adapt to temperature fluctuations and mechanical vibrations, compensating for displacement changes due to expansion or contraction to ensure system stability. Feedback from a construction industry client highlighted the high reliability of Donghao bellows in displacement compensation for pipeline structures, helping address displacement changes.

• Sensing Function: In certain pressure measurement devices, bellows can convert pressure changes into measurable displacement or force, achieving high-precision measurements. This is crucial in precision instruments. A Donghao client in high-tech manufacturing stated that bellows provide stable and accurate feedback in their pressure measurement system.

Key Parameters to Consider When Choosing Bellows: Professional Advice from Donghao

Several key parameters influence the performance of bellows in specific applications:

• Depth Coefficient (k): The depth coefficient determines the height and flexibility of the corrugations. Choosing the appropriate k-value is crucial. If unsure how to choose, please contact our engineers; we’ll provide detailed parameter advice for your project.

• Wall Thickness: Wall thickness affects stiffness and pressure resistance. The thicker the wall, the higher the stiffness but potentially lower flexibility. Donghao offers products with various wall thicknesses to meet different pressure needs.

• Effective Length and Number of Corrugations: Effective length influences working range, while the number of corrugations correlates with stability and strength. Based on specific working conditions, Donghao engineers can recommend the most suitable bellows for you.
