Due to the advantages of simple setup, adaptable usage and also resilience, stainless-steel pipe is typically made use of as gas pipeline. However, the stainless-steel pipeline of gas transmission will additionally be obstructed, so exactly how to eliminate the obstruction of stainless-steel pipe in gas transmission?
One of the most common obstruction of stainless steel pipeline conveying gas is water obstacle, including the condensation of ice water as well as groundwater in the gas. Gas generally has water vapor, which condenses right into water. Once the pressure rises or the temperature decreases, it will certainly flow to the most affordable factor. Additionally, when the groundwater stress is high and the air pressure is reduced, if the pipeline is not limited, deterioration perforation or weld breaking, the groundwater will permeate right into the pipe. When unequal settlement happens in the pipe, condensate is difficult to be gotten rid of in time, and the most affordable factor accumulates to create a ponding area. If the water is not drained pipes in time, the pipe will be obstructed and also the air flow will certainly be decreased, which will certainly influence making use of customers and create abrupt fire and also security accidents. As a result, the stainless-steel gas pipeline need to be equipped with several collection wells (drainage pipes) to eliminate the condensate. When the pipeline is not limited and also enters into the groundwater, the variation boosts greatly. When the unequal settlement of the pipe developing the water belt happens, the method of adjusting the pipe incline or boosting the drainage pipe need to be adopted to remove the water belt.
Reduced pressure stainless-steel pipeline includes a small amount of condensate, while medium and also high pressure stainless steel pipe contains a huge quantity of condensate. Consequently, it is necessary to establish a collection well at the lowest factor of the pipeline to adjust to the pipe pressure degree. The risk-free drain interval depends upon the water volume and also pipe diameter, but is generally no greater than 500m. As a whole, a drainpipe pipeline is installed every 150 to 200 meters in straight pipe sections, and also the customer likewise requires to mount a drainpipe pipeline. The stainless steel pipe above the head generally has a water pump for continuous water drainage. The two-stage pump or the first stage pump is identified according to the air pressure degree. The drainpipe pipe of gas pipe must be equipped with two shutoffs as well as 2 stainless steel tasting pipelines to verify whether the drainpipe pipe is obstructed. The water system of the pump should be outfitted with a shielding funnel to comprise water. The pipe assessor ought to always check the problem of the pump to avoid pump failing and also gas leak.
A drain shutoff is usually installed in the buried stainless-steel pipeline for gas transportation. When the air pressure is high sufficient, it can press straight to the ground. When the atmospheric pressure is low, hand pump can be used to pump water. Whenever the water is released from the water collector, some water has to be retained and the bottom of the pump pipeline can be filled up to avoid the gas from running away with the bottom of the pump pipe. Generally speaking, there is a large amount of condensate water in winter months and the pumping time is short.
