Everyone knows that hydraulic torque wrench is widely used in wind power, petrochemical industry, pipeline, iron and steel metallurgy, shipbuilding, cement, railway machinery repair, heavy machinery, power generation and other industries, especially in the burial and disassembly of some large-sized bolts are an important tool. With convenient use and accurate torque, it has been widely used by users, and recently it has been useful. Households want to understand "Hydraulic wrench for natural gas pipeline maintenance". Next, we will give you a detailed introduction.

　　自然氣輸氣管道維修用電動扳手租要被應用于保送管道螺栓處理計劃中，置信大家對自然氣管道保送系統的結構都不太理解吧，自然氣管道保送系統由管道輸氣站和線路系統兩局部組成。線路系統包括管道、沿線閥室、穿逾越建筑物（見管道穿越工程和管道逾越工程）、陰極維護站（見管道防腐）、管道通訊系統、調度和自動監(jiān)控系統（見管道監(jiān)控）等。輸氣管道可按其用處分集氣管道、輸氣管道、配氣管道等三種。

　　Hydraulic wrench rental for natural gas pipeline maintenance should be applied to the bolt treatment plan of the delivery pipeline. I believe that you do not understand the structure of the natural gas pipeline delivery system. The natural gas pipeline delivery system consists of two parts: the pipeline gas station and the line system. Line system includes pipeline, valve room along the line, crossing building (see pipeline crossing project and pipeline crossing project), cathode maintenance station (see pipeline anticorrosion), pipeline communication system, dispatching and automatic monitoring system (see pipeline monitoring). Gas transmission pipelines can be divided into three types according to their use: gas collecting pipeline, gas transmission pipeline and gas distribution pipeline.

　　為了讓自然氣輸氣管道更好的運用，工人們就需求定期停止檢查和頤養(yǎng)，當自然氣輸氣管道呈現毛病需求維修時，這時分就要運用自然氣輸氣管道維修用電動扳手，它的呈現不只減輕了工人的勞動強度，同時還進步了工作效率，讓整個自然氣輸氣管道維修用電動扳手的強度和韌性都得到了進步。

　　In order to make better use of natural gas pipelines, workers need to stop checking and taking care of themselves regularly. When natural gas pipelines are in trouble and need to be repaired, they need to use hydraulic wrenches for repairing natural gas pipelines at this time. The appearance of hydraulic wrenches not only reduces the labor intensity of workers, but also improves work efficiency, so that the whole natural gas pipeline can be repaired with hydraulic wrenches. The strength and toughness of the hand have improved.

　　大家假如想要選購自然氣輸氣管道維修用電動扳手的話，應該依據下面這三方面作為選購的規(guī)范：

　　If you want to buy hydraulic wrenches for natural gas pipeline maintenance, you should use the following three aspects as the selection criteria:

　　空間位置：沒有空間限制，哪個型號的扳手都能夠運用，通常大家會選用驅動電動扳手，如螺栓擰好后顯露的螺紋較長、螺栓上面有空間有限、螺母間間隔狹窄，好運用中空電動扳手；

　　Spatial position: No space restriction, which type of wrench can be used, usually we will choose to drive hydraulic wrench, such as bolt screwed after the exposed thread is longer, there is limited space on the bolt, narrow nut interval, the best use of hollow hydraulic wrench;

　　螺栓大小：普通有哪幾種螺栓，是公制還是英制。例如M36、M42、M48，這幾種指的是公制螺栓，M36的螺母六角對邊是55，M42是65，M48是75?？蛇x用一種型號的電動扳手。如螺栓規(guī)格跨度太大，而且扭矩跨度較大，那預緊這些螺栓就必然要選用多種型號扳手；

　　Bolt size: What kinds of bolts are common, metric or British? For example, M36, M42, M48, these refer to metric bolts, M36 nut hexagonal diagonal 55, M42 is 65, M48 is 75. One type of hydraulic wrench is available. If the bolt specification span is too large, and the torque span is too large, the pre-tightening of these bolts will inevitably use a variety of types of wrenches;

　　扭矩請求：螺栓的規(guī)格、螺栓的強度等級是電動扭矩扳手選型的關鍵參數。螺栓不同，扭矩不同，同樣的螺栓強度等級不同扭矩不同，同樣螺栓強度等級，不同工況的扭矩也不同。如M36螺栓，強度等級8.8 級，扭矩1764Nm；強度等級10.9. 級，扭矩2453Nm；強度等級12.9.級，扭矩2940Nm 每個行業(yè)不同，螺栓等級強度不同，詳細狀況詳細看待。

　　Torque Requirement: The specifications of bolts and the strength grade of bolts are the most critical parameters for the selection of hydraulic torque wrenches. Different bolts, different torques, the same bolt strength level, different torques, the same bolt strength level, different working conditions of the torque are also different. For example, M36 bolts, strength grade 8.8, torque 1764Nm; strength grade 10.9, torque 2453Nm; strength grade 12.9, torque 2940Nm for each industry, bolt grade strength is different, the detailed situation is looked at in detail.
