Anti-shock safety protection device for natural gas pipeline

Abstract

The invention provides an anti-shock safety protection device for natural gas pipelines, which includes an external protective shell, and a plurality of pipe fixing devices and inter-pipe fixing devices are arranged inside the outer protective shell, and the inter-pipe fixing devices and the pipe fixing devices are arranged at intervals; The fixing device includes an upper block and a lower block that are combined with each other. The inner wall of the upper block is provided with a semicircular upper fixing groove, and the inner wall of the lower block is provided with a semicircular lower fixing groove. There is also a buffer plate fixed on the block; a fixed cushion is arranged between the pipe fixing device and the outer protective shell; A fixed protective layer is arranged between the outer protective shells. The safety protection device of the present invention can resist impact force and form multiple protections, which can not only protect the stability of the joint of the pipeline, but also protect the middle of the pipeline from being damaged by the impact force, thereby ensuring the safe transportation of natural gas.

Description

technical field [0001] The invention belongs to the technical field of protection, in particular to an impact-resistant safety protection device for natural gas pipelines. Background technique [0002] Natural gas pipelines are pipelines that transport natural gas (including associated gas produced in oil fields) from mining sites or processing plants to urban gas distribution centers or industrial enterprise users, also known as gas pipelines. The use of natural gas pipelines to transport natural gas is the only way to transport large quantities of natural gas on land. As the use of natural gas becomes more common, the demand for natural gas pipelines is also increasing. More and more cities have begun to lay natural gas pipelines. The pipelines in the soil will also be affected by the load, which can easily damage the natural gas pipelines and affect the safety of gas transmission. At the same time, because the natural gas installation route is relatively long, the pipeli...

Problems solved by technology

As the use of natural gas becomes more common, the demand for natural gas pipelines is also increasing. More and more cities have begun to lay natural gas pipelines. The pipelines in the soil will also be affected by the load, which can easily damage the natural gas pipelines and affect the safety of gas transmission. At the same time, because the natural gas installation route is relatively long, the pipelines are connected by welding, but the welds between the pipelines are relatively fragile. Natural gas leakage caused by fracture is easy to occur; currently there is no corresponding protective device that can solve the above two problems at the same time
