The metal bellows is a regular wave-like pipe. Commonly used metal bellows include carbon steel, stainless steel, steel lined with plastic, aluminum, etc. It is mainly used for non-concentric axial transmission with a small bending radius, or irregular turning, expansion, or absorption of thermal deformation of the pipeline, or where it is not convenient to use a fixed elbow to connect the pipeline to the pipeline, or the pipeline and the pipeline Connected use of equipment.
The metal corrugated pipe billet is made of thin-walled stainless steel welded pipe with corrugated processing, which is rich in flexibility and has good temperature and pressure resistance. It is suitable for the transportation of various industrial gases such as air, steam, and various fluid media such as water, oil, medicine, etc. It plays an important role in the reciprocating motion of the pipe system, absorption of thermal expansion, vibration absorption, and central adjustment of piping.
The metal corrugated pipe billet is the best supporting product for metal hoses, corrugated pipes, corrugated pipe compensators, corrugated pipe billets, automobile exhaust pipes, high-pressure hoses, cable threading pipes, etc. Divided into two varieties, soft and hard, bright and soft, reliable in quality and complete in specifications. The product is corrosion-resistant, clean and beautiful in appearance, can increase the pressure of the finished hose, high and low temperature resistance, extend the service life of the pipe body, and reduce costs. It is widely used in machinery, chemical industry, metallurgy, construction and other industries.
The product structure of steel corrugated pipes is divided into integral and assembled shapes; cross-sectional shapes include round, oval, horseshoe, arch, etc. The pipe diameter ranges from 0.3m-12m, and the processing thickness is 1.6mm--7mm, which can meet the needs of structures with a filling height of 0.5m-60m on the top of the pipe.
The materials required for the produced steel corrugated pipes have very high requirements. However, under normal circumstances, the required materials only need to meet the following conditions:
1. The required material must have very good plasticity, which is conducive to the elastic properties and processing of the steel bellows, and with subsequent processing to obtain higher elasticity and required strength.
2. The material must have tensile strength and fatigue strength, so that it can fully ensure the normal performance of the elastic function.
3. Must have a strong welding ability, and also meet the requirements of welding.
4. Elasticity is the main reason for the material, because the steel bellows is often affected by time and temperature changes.
5. The required materials must have sufficient corrosion resistance to ensure the service life and safety of the steel bellows in the project.
