Description

自承压超长复合内衬软管的一次成型生产设备One-shot production equipment for self-pressing and super long composite lining hose 技术领域：Technical field:
本发明涉及一种自承压超长复合内衬软管的一次成型生产设备，属于流体传送装备技术领域。The invention relates to a primary molding production equipment for a self-pressing and super long composite lining hose, and belongs to the technical field of fluid conveying equipment.

油气管线由于内腐蚀，造成管线使用寿命不足、乃至出现管道失效的风险，甚至导致严重的泄漏与安全事故。这种情况在全球业内屡见不鲜。腐蚀是金属材料无法避免的现象，由此而造成管体壁厚不断变薄，乃至出现泄漏风险，威胁管道的完整性。由腐蚀造成的管道泄漏事故层出不穷，对企业的正常生产、经济运行，乃至企业以及周边社会的安全构成了极大的威胁。非金属内衬可以从根本上解决金属的腐蚀问题。但传统内衬软管都是由橡胶或树脂制作成的内衬软管，工序多，运输不方便，长度的局限性，承压能力不高，具有操作安全隐患。Due to internal corrosion, oil and gas pipelines cause insufficient pipeline service life and even the risk of pipeline failure, and even lead to serious leakage and safety accidents. This situation is not uncommon in the global industry. Corrosion is a phenomenon that metal materials cannot be avoided. As a result, the wall thickness of the pipe body is continuously thinned, and the risk of leakage is threatened, which threatens the integrity of the pipe. Pipeline leakage accidents caused by corrosion are endless, posing a great threat to the normal production, economic operation of enterprises, and even the safety of enterprises and surrounding society. Non-metallic linings can fundamentally solve the problem of corrosion of metals. However, the traditional lining hoses are lining hoses made of rubber or resin. The process is numerous, the transportation is inconvenient, the length is limited, the pressure bearing capacity is not high, and there is a hidden danger of operation.

Even if the fluid penetrates into the reinforcement layer during use, it will not affect the blasting. The length is several kilometers and the winding is particularly easy.
