Analysis of Standard Specifications for Metal Bellows

1. Basic concepts of metal bellows

Metal corrugated pipe is a flexible pipe with a corrugated exterior and a smooth interior. It has good bending ability and high temperature and pressure resistance. It consists of conduits, auxiliary pipes and bellows, and is widely used in petrochemical, energy, aerospace, medical, light industry and other fields.

2. Material requirements for metal bellows

1. Guide and auxiliary pipes must be produced in accordance with the requirements of GB/T3639, GB/T8162 and GB/T8163 standards.

2. The outer and inner layers of the corrugated pipe should be made of stainless steel strips of different thicknesses and strengths, which should be made through special molding and processing techniques.

3. Process requirements for metal corrugated pipes

1. The forming of corrugated pipes should adopt advanced cold forming processing technology to ensure the pipe forming accuracy and surface quality.

2. During the processing, the core line accuracy and dimensional accuracy of the pipe must be ensured, especially the dimensional tolerance requirements for the corrugated part are relatively high.

4. Processing requirements for metal corrugated pipes

1. Bellows must undergo specification testing before processing to ensure that product size, shape, etc. meet the requirements of standard specifications.

2. During the processing, the processing should be carried out in accordance with the specification requirements, and the process flow of each link should be strictly followed to ensure the quality and performance of the product.

5. Detection requirements for metal corrugated pipes

1. During the production process, strict testing must be carried out to ensure that the product meets the standard requirements.

2. The inspection content includes appearance, size, welding quality, wave shape, wall thickness, etc., and advanced inspection equipment and technology are used for inspection.

【in conclusion】

Metal corrugated pipe is a high-performance, high-reliability flexible pipe with a wide range of applications. It has very high standards and specifications in terms of materials, technology, processing and testing. Only by strictly following the standard specifications for production, processing and testing can we produce metal corrugated pipe products with excellent quality and stable performance.
