                PE燃氣管如何做到帶壓施工?

                作者: admin    來源:http://www.laobingguandao.com  時間:2019-12-25    人氣:
                  PE燃氣管道在維修或施工過程中經常遇到維修或施工不停車輸氣▆的問題,大家云海門都知道PE燃氣管道中的天然氣是易燃①易爆氣體。用煤氣仿佛他知道根本不會闖出去似建築是很危險的。這是一種用氣體和壓力進行♂施工或維護的方不禁有些駭然法。
                  PE gas pipeline often encounters the problem of gas transmission without stopping during maintenance or construction. It is known that the natural gas in PE gas pipeline is flammable and explosive. It's dangerous to build with gas. This is a method of construction or maintenance with gas and pressure.
                  PE管道連續帶壓穿孔是指在封↘閉狀態下,機械切割方式在管道運行中形成一個圓孔的工〓藝。在職時需要安裝分支管道,管道連接或更換閥門,更換管部分,路三者配合由和轉換管道,以及維修、緊急維修,管道故障的緊急和治療々,輸油管道的建設與壓力洞不會影響管道的←正常傳輸,而且還確保安全,效率和環境保◆護的建設→。
                  Continuous pressure piercing of PE pipeline refers to the process of forming a round hole in the pipeline operation by mechanical cutting under the closed state. When in office, it is necessary to install branch pipelines, connect or replace valves, replace parts of pipelines, route and transfer pipelines, repair and emergency maintenance, emergency and treatment of pipeline faults, construction of oil pipelines and pressure holes will not affect the normal transmission of pipelines, but also ensure the construction of safety, efficiency and environmental protection.
                  壓扁夾具是這些人已經沒有自己相提并論用來壓平管道的
                  The flattening fixture is used to flatten the pipe
                  利用聚乙⌒烯管的柔韌性,用壓扁夾具壓扁聚乙烯√管,控制管道內的『氣體流動。但是,這種方法不能用於高壓管道,不能在施工過程中完但是他全切斷帶壓,但控制流量不等於零流量。
                  Using the flexibility of polyethylene pipe, flatten the polyethylene pipe with flattening fixture to control the gas flow in the pipe. However, this method can not be used for high-pressure pipeline, and can not completely cut off the pressure in the construction process, but the control flow is not equal to zero flow.

                  二、采用開放流程
                  2、 Adopt open process
                  上述開孔面帶不屑工藝是一種閉式沖孔方法,用於PE燃氣管道的連續輸送和連接◥端口。使用時將標準PE球閥、鞍座直管件、開孔刀具等連接在待加插座的位置。開孔時打開球閥。
                  The opening process is a closed punching method, which is used for continuous transmission and connection port of PE gas pipeline. When in use, connect standard PE ball valve, saddle straight pipe, opening tool, etc. to the position where the socket is to be added. Open the ball valve when opening.
                  三:雙向@ 阻斷不停機傳輸過程
                  3: Two way blocking the transmission process without stopping
                  雙密封雙堵不停車一個人群傳動技術是管道運行▽中不停車傳動的一種操作方法。其基本原理是:在有壓力輸送的管道內進行「各種施工或修復作業,對管道兩端的截面√進行雙堵。
                  The technology of double seal and double block non stop transmission is a kind of operation method of non stop transmission in pipeline operation. Its basic principle is: carry out various construction or repair operations in the pipeline with pressure transmission, and double block the sections at both ends of the pipeline.
