管线

If the ambient temperature falls below 15C,the line heat tracing systems should be turned on .

如坏境温度降到15C，管线的伴热系统将应投入使用。

Some problems, such as serious pipe corrosion and unstable acid-base property, and the solutions are presented.

提出目前存在着管线腐蚀严重、水的酸碱性不稳定等问题及解决的方法。

After the analysis in Hulunber 301 section, the corrosion occurs mainly in inner corrosion and the outer corrosion is indistinctness. In affusion and heating system, the corrosion gives priority to oxygen corrosion, which the supplement of animalcule corrosion and carbon dioxide corrosion. In life drinking water system, the corrosion in stainless steel jar and pipeline wall usually generate welding line corrosion.

分析发现：贝301区块发生的腐蚀以内腐蚀为主，外腐蚀不明显；注水系统和采暖系统以氧腐蚀为主，微生物腐蚀为辅；还发生了以氢去极化为主的二氧化碳腐蚀；生活饮用水系统不锈钢罐及管线内壁发生的腐蚀主要是焊缝腐蚀。

NOTE: DO NOT reduce the size of the drain line from the air gap fitting.

注意：不要缩小从气隙接出的排放管线的口径。

In order to make the right evaluation of the state which is the consumption consume of the steam line system, we make an test of the heat loss of the steam line network. And we also probe into the heat loss of the steam line system and the factors. In order to solve the heat inefficency of the steam line system, we look into the present situation of the steam line network and the state of heat preservation. Then we found the open questions and the weak points of heat preservation. We make the evaluation and affirm the reason of the heat inefficency of the system. We adopted the combination of bench test and engineering optimization, then we screened out high-quality adiabator, and designed the best heating composition. We designed and developed the software"The analysis and optimization of energy of the steam line system in thermal production" It can offer convenience to the computational analysis of heat loss of the steam line system. It can also be used for design calculation and experimental verification of steam pipeline feasible radial-radius, so it can offer technical support for the reduce of heat loss of the system, the raise of well head steam quality and the raise of heat efficicency of the steam injection system.
