PE pipe purchase-purchase of buried PE pipe fittings for gas

         Buried PE pipe fittings for gas are a new type of plastic pipe that is being popularized. In use, the gas pipe must bear a certain pressure and cannot leak, otherwise serious damage may occur. 燃气用埋地 PE管材管件 时,一定要注意以下几个方面: Therefore, when purchasing buried PE pipe fittings for gas , we must pay attention to the following aspects:

购买具备 PE燃气管生产许可证的生产企业的产品 I. Purchasing the products of a production enterprise with a PE gas pipe production license .

可目测 PE管材管件 ,选择色泽基本均匀一致,内外壁光滑、平整,无气泡、凹陷、杂质等影响表面性能缺陷的管道,必要时还可以切割下一小条,观察表面是否有光泽,弯曲应柔软耐折 Second, PE pipes and fittings can be visually inspected , and the color and luster are basically uniform, and the inner and outer walls are smooth and flat, and there are no bubbles, depressions, impurities, etc. that affect surface performance defects. If necessary, you can also cut the next strip to observe whether the surface is shiny. , Bending should be soft and folding resistant .

要看燃气用埋地 PE管材管件上标识是否齐全,应有型号规格、执行标准、生产厂家等,并检查标识是否与实际相符,查看企业合格证和权威检测机构的抽样检测报告等。 3. It depends on whether the markings on the buried PE pipes and fittings for gas are complete, including model specifications, implementation standards, manufacturers, etc., and check whether the markings are consistent with the actual situation, and check the enterprise certificate and the sampling test report of the authoritative testing agency. Don't buy San Wu products.

使用燃气用埋地 PE管材管件 ,最好选择大厂并有相当熔焊接(电熔或热熔对接)手段、技术的生产和施工企业,以避免 PE管材管件 在较大内压和长久使用中出现熔缝处渗漏 4. When using buried PE pipe fittings for gas , it is best to choose a large factory and a production and construction enterprise with considerable fusion welding (electric fusion or thermal fusion butt) means, technology, to avoid the PE pipe fittings under a large internal pressure And long-term use leakage in the weld .

在填埋 燃气用埋地 PE管材管件 时一定要 严格按施工规范进行施工,因为在管道填埋较浅的工程中,又出现较大负压的情况下,管壁较薄的管道会被吸扁而使输水系统报废,不按规范施工则在回填中一旦近管身处有尖锐硬物则会扎入或扎穿管壁导致使用寿命减短或破漏。 V. When filling buried PE pipes and fittings for gas use, construction must be carried out in strict accordance with the construction specifications, because in the case of shallow landfill projects, under the condition of large negative pressure, pipes with thin pipe walls will The water conveyance system is scrapped because it is sucked flat. If it is not constructed in accordance with the specifications, once there is a sharp and hard object near the pipe body, it will penetrate or penetrate through the pipe wall, resulting in shortened service life or leakage.
