High-density polyethylene jacket tube is widely used in oil pipelines, gas pipelines, urban heating pipes, water pipes, electricity and other corrosion engineering, product quality and service by the users of a good level.
HDPE pipe ideal suitable for many different applications, including municipal, industrial, energy, geothermal, landfill and so on. HDPE pipe strength, durability, flexibility, weight of light welding after the high density polyethylene to zero leakage rate, because the welding process formed a whole HDPE system.
高密度聚乙烯管相对环境友好，因为它无毒、耐腐蚀和耐化学腐蚀，设计寿命长，并且由于灵活性，删除适用于无沟槽安装方法。
制造支架时应添加抗氧化剂、紫外线稳定剂和炭黑等。聚乙烯护套管易老化，如露天存放的篷布等物品宜遮盖，堆放时应远离高热和大火，防腐钢管制成后禁止暴露，突然受冷，或聚乙烯护套管易开裂，影响产品性能和使用寿命。

应用领域：海底管道、酸性管道、冷床甲烷排放、腐蚀性废物、脱水、工艺水管、排水管道、光纤内管道、飞灰处理、重新铺设盐水进水口和污水管道。
下面将进一步详细介绍一些有趣的应用程序。
海底管道：HDPE管道对该应用特别感兴趣。凭借其灵活性，HDPE管道自动适应地形配置的最小半径限制。海底管道用作压力管线，例如饮用水管线、重力流管线和电缆导管。
海底设施可能包括一条或多条并排铺设的管道，或将其组合成一个管束。海底管道的安装采用三种不同的方法之一，具体取决于要穿越的水域范围、河床性质和安全要求。
HDPE lined steel pipe slightly larger than the outer diameter of tube technology is the main channel diameter HDPE liner, after necking, making cross-section smaller than the cross-sectional area of the main channel, in the role of traction quickly insert the main channel.
HDPE Lined Pipe Fittings, and short straight sections of steel pipe are often needed to terminate the pipeline, or for use in areas where larger radius bends cannot be accommodated.
钢管线轴,or fittings, are fabricated with weld neck flanges to connect with the HDPE-lined steel pipeline.
Seal Connection for these more demanding applications:
利用多个self-ene密封法兰连接rgized seals and are designed to ASME B16.5 up to Class 2500 rating.
High Density Polyethylene (HDPE) Jacketed System is designed for piping systems above or below ground suitable for inside or outside applications. High quality polyurethane foam insulation combined with a durable watertight jacket supplied in 20' or 40' lengths, means an economical, high-quality system.
高密度聚乙烯护套防腐结构：the outer surface of pipe wrapped in high-density polyethylene material, with a high mechanical strength and excellent corrosion resistance, can protect the steel in the transportation, installation and use of the process to avoid external factors the damage.
规范、标准和标识Welded steel pipe (steel pipe manufactured with a weld) is a tubular product made out of flat plates, known as skelp, that are formed, bent and prepared for welding.
Our team is highly trained and experienced in servicing and producing all types of steel supplies.
