Description

TECHNICAL FIELD

[0001] The utility model relates to pipeline device technical field, concretely relates to sliding pipe support device for torch gas pipeline. BACKGROUND

[0002] In petrochemical plants, the torch gas pipeline system is an important component to ensure production safety. The torch system is used to collect and process flammable and explosive gases generated during production, ensuring that they can be safely discharged in abnormal conditions. The torch gas pipeline is usually composed of a torch gas collection pipe network, a torch device, and a gas tank device. The torch pipe network collects flammable and explosive gases from various devices or equipment into the torch main pipe, which is then transported to the torch device for processing. Under normal operating conditions, the torch gas is usually recycled to the gas tank device and sent to the fuel gas pipe network after desulfurization for use as fuel. In abnormal conditions, when the torch gas cannot be recycled, it needs to be burned and treated by the torch device. Because the torch discharge is large, the nominal diameter of the torch line pipe is also large. According to the value of the horizontal thrust of the fixed pipe support of the combustible gas discharge pipe with condensate liquid in Article 7.2.4 of the "SH3009-2013 Petrochemical Combustible Gas Discharge System Design Specification", when the nominal diameter of the torch gas pipeline is 1000mm or more, the thrust of the fixed pipe support should not be less than 15 tons. If the carrying capacity of the pipe gallery design column and beam is insufficient, it cannot withstand such a large horizontal thrust, which may cause safety hazards to the pipe gallery structure.

[0003] Pipe support is an important component of the torch gas pipeline system, mainly used to support and fix the pipe to ensure its stability during operation. The sliding pipe support allows the pipe to slide within a certain range when it expands or contracts due to heat, effectively reducing stress concentration and preventing damage due to deformation. However, the sliding pipe support can absorb part of the thrust, but not completely, and the remaining thrust will be transmitted to the pipe gallery through the pipe support. The sliding end of the sliding pipe support is in direct contact with the pipe, and the contact points are all steel structures. The dynamic friction coefficient between steel and steel without lubrication is about 0.15. This high friction coefficient will cause a large friction force on the pipe support, which in turn will generate a large horizontal thrust on the pipe gallery structure. Especially when the torch pipeline is in abnormal discharge, the pipe will receive a larger horizontal thrust, which may cause a larger impact on the pipe gallery, leading to tilting or even collapse of the pipe gallery. In addition, in addition to the horizontal thrust, the pipe may also twist or change in radial size due to changes in temperature, pressure, and other environmental factors. However, the existing sliding pipe support often cannot adaptively deform, which may also generate some stress. SUMMARY

[0004] The technical problem to be solved by the utility model is to provide a sliding pipe support device for torch gas pipeline, which reduces the impact on the pipe gallery during abnormal torch discharge, avoids the safety accidents caused by excessive horizontal thrust, and avoids stress caused by pipe twisting or radial size change.

The pipeline is a steel structure, the fixed block can be fixed to the pipeline by welding, and the materials of the arc-shaped backing plate and the rolling ball are selected from materials with high hardness, high wear resistance and low friction coefficient, preferably ceramic or stainless steel.
