Shanghai Songjiang Vibration Absorber Group Co., Ltd. manufactures various stainless steel metal bellows products, mainly including universal metal bellows products. We are a manufacturer of universal metal bellows in Shanghai, and our company offers a 3-year product warranty.
Below are some introduction parameters of universal metal bellows provided by the technical department of Shanghai Songjiang Group for everyone’s reference and learning, to facilitate future procurement.
Application: Used for connecting cold and hot air conditioning water and ventilation pipelines in building engineering to effectively compensate for axial displacement and absorb vibration, ensuring the safe operation of pipelines.
Features of Shanghai Universal Metal Bellows:
These metal bellows are composed of one or more bellows tubes connected in series, with an outer cover that allows axial movement of the bellows tubes. This type of metal bellows only absorbs axial displacement.
The outer cover serves as both a protective device and maintains its stability for metal bellows with multiple wave numbers.
It saves installation space for piping, is convenient for construction, meets the requirements of modern buildings for new types of pipe fittings, and has broad market prospects.
Performance Parameters:
Type: Single and double metal bellows
Nominal diameter: DN40～1200MM
Temperature: -20°C to 120°C
Medium: Fire-fighting pipelines, cold and hot air conditioning water, pipeline ventilation
Nominal pressure: ≤1.6MPA
Materials: Bellows and flow sleeves made of high-quality stainless steel, others made of carbon steel
Flange standard: Generally, JB/T81-94-RF is adopted, and can be selected according to customer requirements.
Axial internal pressure metal bellows (Model: BN)
Displacement direction: Axial
Working pressure: (MPa) 0.6, 1.0, 2.5
Nominal diameter: DN15～DN3000
This expansion joint consists of a bellows tube and structure, mainly used to absorb axial displacement. It has a simple structure, low cost, and is also known as a universal metal bellows.
