Description
TECHNICAL FIELD
[0001] The utility model relates to pipeline technical field, specifically point to a kind of stainless steel pipeline with shock-absorbing connecting clamp. BACKGROUND
[0002] Stainless steel pipeline is a pipeline made of stainless steel, with many excellent properties. It is composed of iron, chromium, nickel and other elements. The chromium element forms a dense chromium oxide protective film on its surface, which can effectively prevent corrosion and rust, and has good corrosion resistance in various harsh environments. At the same time, stainless steel pipeline also has high strength, good toughness and heat resistance, and can withstand high pressure and temperature.
[0003] In the current project, when the stainless steel pipeline is arranged on the ground, it is very important to protect the surface of the pipeline. To protect the surface of the pipeline, a pad is usually used to raise the pipeline, so that it maintains a certain distance from the ground. This measure can effectively avoid the damage to the passivation film caused by the friction of sand and water erosion on the ground. However, this treatment method has obvious disadvantages, especially the poor anti-vibration performance. Especially at the joint of the pipeline, in the vibration environment, the frequent relative displacement between the pipelines can easily cause damage to the contact point at the joint due to stress concentration, thereby affecting the stability and service life of the entire pipeline system. SUMMARY

[0014] Further, the connecting plate is an arc-shaped plate, and the two ends of the connecting plate are connected with the upper support plate and the inner side wall of the outer ring seat body, respectively.

The hook spring connects the lower clamp and the outer ring seat body, absorbs energy by elastic deformation, plays a good buffering role when the pipelines vibrate, and effectively protects the safety of the pipelines.
[0017] The middle parts of the upper support plate and the lower support plate of the inner ring support plate protrude upward and are connected, and the shock-absorbing block is arranged above the joint, so that the vibration impact from different directions can be effectively buffered.
