Flexible Metal Conduit application technology has strong practicability and can solve the problem of serious settlement of pipelines. It has the following process characteristics:
(1) Compensation pipeline facilities have a large amount of sinking displacement.
The introduction tube and the riser are connected by a stainless steel metal hose, and the upper and lower disturbance range (twice the one-side disturbance) is the displacement of the introduction tube to allow settlement by the pre-disturbed installation of the stainless steel metal hose. According to the selection of the nominal diameter and total length of the stainless steel metal hose, the upper and lower disturbance ranges can be determined.
(2) The settlement can be directly observed and quantified.
Ground subsidence and pipeline sinking are not synchronized, and the degree is different; pipeline sinking is driven by ground subsidence, and underground pipeline operation is difficult to observe, predict and judge, and there are major difficulties in risk assessment. The process accurately calculates the sinking capacity of the pipeline facility by observing and measuring the deflection of the stainless steel metal Flexible Conduit. Therefore, the sinking situation is more accurately grasped, and the rectification judgment is made in advance according to the deflection utilization situation, so that the sinking safety hazard has obvious predictability.

(3) Reduce the installation stress of the pipeline.
Steel pipe welding will bring installation stress to the gas pipeline. Once the pipeline is deflected by the external force, the stress at the local point of the pipeline will increase rapidly, and the riser will appear as an arc-shaped slope. Due to the nature of the stainless steel metal hose, the application of this process will minimize the installation stress, allowing the pipe to avoid stresses caused by hard joints and further stress increases in the future.
(4) There are many specifications of Flexible Metal Conduits, and the range of disturbance can be changed according to different choices.
According to the selection of the nominal diameter and total length of the stainless steel metal hose, the upper and lower disturbance ranges can be selected indirectly, and the disturbance range can also be adjusted by series combination, which can meet the pre-settling requirements of various situations.
