PE燃气管定义？
以聚乙烯树脂为主要原料，经挤出成型的燃气用埋地聚乙烯管材，简称PE燃气管。PE燃气管道是什么颜色？
管材的颜色为黄色或黑色，黑色管上必须有醒目的黄色色条。PE燃气管的产品规格有哪些？
标准尺寸比SDR17.6 φ20～φ630 0.2MPa 标准尺寸比SDR11 φ20～φ630 0.4MPa为什么SDR11系列适用于输送人工煤气和液化石油气？
根据ISO4437：1988（E）A1规定：“如在管材的全部使用期间要与液态烃（冷凝液、加臭剂或芳香烃）接触，则对于50年寿命推荐使用SDR11（S5）系列的管材。我国人工煤气和液化石油气中一般均含有液态烃，因此规定SDR11适用于输送天然气，人工煤气和液化石油气。
两个系列管材的最大允许工作压力各是多少？ 在20℃的情况下，SDR11系列最大的允许工作压力是0.4MPa，SDR17.6系列最大的允许工作压力是0.2MPa。
PE燃气管的优点体现在哪些方面？ 1）强度高、耐应力开裂性能优良、抗蠕变性能好； 2）韧性、挠性好，对基础不均和错位的适应能力强，可抵抗地震和台风等恶劣环境； 3）具有良好的耐候性（包括抗紫外线）和长期热稳定性； 4）耐腐蚀，使用寿命长，适合输送天然气、液化石油气和煤气； 5）内壁光滑，流通能力大，燃气流速可以达到20m/s，节约运行费用； 6）耐磨性能好，抗磨损； 7）抗低温冲击性能好，可在-20-40度温度范围内安全使用，冬季施工不受影响； 8）热熔（或电熔）连接方便可靠，施工和维护简便（其间可不停气）； 9）全面适合传统的开挖施工方式和顶管、定向钻孔、衬管、裂管、沉入水下等全新的非开挖技术； 10）聚乙烯原料只含有碳、氢两种元素，对环境无害，绿色环保。

The production headquarters of Shandong Qicheng Pipe Industry Co., Ltd. is located in Mengshan Industrial Park, Linyi City. The company mainly engaged in PE pipe, pipe fittings and other products. The company enjoys a superior geographical position and has the advantage of connecting sea, land and air. It is adjacent to the four major ports in the east, Laoshan Port, Rizhao Port, Lianyungang Port and Qingdao Port. The advantages of shipping are very obvious. The three highways of Beijing, Shanghai, Ridong and Qinglan are criss-crossed and the road traffic is very convenient. The Jiaoxin Railway and the Yanshi Railway are directly connected to Linyi. Linyi Airport, which is only 20 kilometers away from the company, has opened dozens of routes, making it easier for the company to travel with other places.
The company was established in 2008 and is a member of the China Plastic Pipeline Committee. It is a member of the Shanghai and Jiangsu Chemical Building Materials Association. As a national key high-tech enterprise, the industries involved are: plastic pipe production, mold development, manufacturing, polymer materials disciplines, etc., specializing in all kinds of new plastic building materials equipment and products of high-tech industrial companies, professional to provide customers with Water supply polyethylene (PE) pipe, pipe fittings and other series of national standard products. The annual productivity has reached more than 20,000 tons, with assets of over 100 million yuan and more than 100 sets of equipment.
In order to adapt to the market demand and better serve the majority of users, in 2009 passed the ISO9001 quality management system certification, and has introduced a number of pipeline production lines with the world's advanced technology level from abroad, the goal of corporate products to brand words One step!
