/ / / /对于热熔连接和电熔连接你了解多少How much do you know about hot melt connection and fused connection 电熔衔接（适用管径dn630mm）：将PE管材完整插入电熔管件内；将专用电熔机两导线分别接通电熔管件正负两级；接通电源加热电热丝使内部接触处FE熔融；冷却终了；施工终了后需经试压验收合格后，方可封管投入运用。法兰衔接，钢塑衔接，鞍型对接装置，这对处理主管道分流特别有效。Fused cohesion (suitable diameter dn630mm) : insert the PE pipe full fused fittings; Will special fused machine respectively connected the two wires fused fittings of plus or minus two levels; Switch on the power heating heating wire to make internal contact FE melting; At the end of cooling; Upon the acceptance of construction need to the test after the end of, before sealing pipe is put into use. Flange connection, gangsu cohesion, saddle shaped docking device, the processing main diversion especially effective. 热熔衔接可以热熔衔接是聚烯烃（包括聚乙烯、聚丙烯和聚丁烯）资料管道系统的突出优点。可以热熔衔接的含义是聚乙烯管材、管件能够经过热熔衔接起来并且衔接处的强度超越管材管件的本体强度。聚乙烯管段能够经过热熔对接连生长管并且直径根本不变，这就为采用非开挖铺设和应用于管道内衬修补发明了条件。聚乙烯管道系统的热熔衔接方式有热熔对接（包括鞍型衔接）和热熔承插衔接。热熔承插衔接适用于直径比拟小的管材、管件（普通直径在DN63mm以下），由于直径小的管材、管件管壁较薄，截面较小，采用对接不易保证质量。Hot melt can melt cohesion is polyolefine (including polyethylene, polypropylene and poly (butylene) data highlight the advantages of pipe system. Can be the meaning of the hot melt connection is polyethylene pipes, pipe fittings can link up with hot melt and beyond the intensity of connecting pipe fitting frame strength. Polyethylene pipe section can after hot melt for continued growth and tube diameter is constant, for adopting trenchless laying and invented the conditions applied to the pipe lining repair. Polyethylene pipe system of hot melt connection way has a hot melt docking (including saddle shaped cohesion) and hot melt socket connection. Hot melt socket connection is suitable for compare with small diameter pipes, pipe fittings (average diameter under DN63mm), due to the small diameter pipes, pipe fittings with thin wall, cross section is small, use docking is not easy to ensure the quality. 热熔对接合适于直径比拟大的管材管件，比承插衔接用料省、易制造，并且，在熔接前切去氧化外表层，熔接压力能够控制，质量较易保证。从开展意向看，给水管道才用热熔对流是主流。聚乙烯管道系统的热熔衔接的工艺和设备（工具）都比拟简单，热熔衔接质量稳定的保证主要是依托严厉恪守规则的操作规程（特别是要严厉控制好温度、压力和时间三个参数）。电熔链接电熔衔接包括电熔承插衔接和电熔鞍型衔接。电熔衔接的突出优点是质量牢靠（减少以为要素）和施工效率高。Hot melt docking in compare with large diameter pipe fitting, right than a socket connection with makings provinces, easy manufacture, and the outer surface before welding and cutting to oxidation, can control the welding pressure, quality is easy to guarantee. Intention to see, from the feed water pipe with hot melt convection is the mainstream. Polyethylene pipe system of hot melt connection technology and equipment simple (tools) are compared, the hot melt connection the assurance of quality stability is mainly rely on strict adherence to rules of procedures (especially to strict control the temperature, pressure and time three parameters). Fused link fused including fused socket cohesion and fused saddle shaped cohesion. Fused bridging the prominent advantage is the quality of solid elements (reducing thought) and high construction efficiency. 但由于电熔管件的制造技术请求较高，其本钱也较高。电熔衔接主要应用在直径较小的燃气管道系统热水锅炉价格。电熔衔接质量稳定的保证主要是依托严厉恪守规则的操作规程和电熔管件的质量。机械衔接机械衔接包括卡箍式衔接和卡压式衔接两种。But as a result of fused fittings manufacturing technology request is higher, its capital is higher also. Fused cohesion is mainly used in small diameter gas pipeline system. Fused bridging the assurance of quality stability is mainly rely on strict adherence to rules, procedures and the quality of the fused fittings. Mechanical mechanical cohesion including clamp cohesion and conformity of two kinds of cohesion. 虽然聚乙烯管道系统主要采用热熔衔接和电熔衔接，但是在某些应用场所聚乙烯管道系统采用机械更便当、更经济。例如在聚乙烯管道系统的修理中，有时不便当或不可能采用热熔衔接或电熔衔接。如在地坑中修理被损坏的埋地管道，现场条件不可能保证衔接处无水；又如需求在野外衔接少量大直径管道时，采用热熔衔接需求专用设备可能很不经济；还有，在需求把聚乙烯管道和其它管道衔接时，也需求采用机械衔接锅炉省煤器。泰聚乙烯非开挖铺设技术非开挖铺设技术包括新管道的非开挖铺设和旧管道的非开挖修复（防止重新开挖，既能够应用于压力管也能够应用于无压力管）在不少场所采用非开挖铺设能够明显的进步效率降低工程费用，以至在某些场所是独一可行的铺设办法（例如要穿过忙碌的道路和失去）。Although polyethylene pipe system mainly USES the hot melt connection and fused together, but in some application places PE pipe system the mechanical bento and more economic. In in the repair of polyethylene pipe system, for example, when sometimes the inconvenience or cant use hot melt joining or fused. Such as repair damaged buried in a hole in the ground pipeline, site conditions cant ensure cohesion without water; And as demand in the wild join a small amount of large diameter pipe, a heat cohesion needs special equipment may be not economy; Also, polyethylene pipe and other pipe connection on the demand, also need use mechanical cohesion. Ty PE trenchless laying of trenchless laying technology including the old and new pipeline trenchless laying of trenchless pipe repair, prevent to excavation, both can be used in the pressure vessel can also be applied to the pressure pipe) in many places trenchless laying can obvious progress efficiency are adopted to decrease the engineering cost, is that in some places, the feasible laying method (for example, to cross a busy road and loss). 近年来世界各国都在大量开发和推行各种非开挖技术，由于不只有经济上的效益，还有利于环境的维护（防止开挖后对环境的毁坏）。聚乙烯管道系统应为具有柔韧和能够熔接的特性，特别合适采用非开挖铺设技术。内在此范畴近年也有很快进步酿酒设备，在新管道的非开挖铺设和旧管道的非开挖修复两方面都曾经有许多胜利的工程案例。在新管道的非开挖铺设方面主要采用定向钻孔拖入聚乙烯长管的工艺，在旧管道的非开挖修复方面“滑衬办法”（衬于管径略小于旧管内径）和“变形衬管办法”（聚乙烯长管略缩径插入，恢复后贴衬于旧管内壁）都曾经在普遍运用。In recent years, all countries in the world in the development and implementation of various kinds of trenchless technology, not only economic benefits, and environmental maintenance (to prevent damage to the environment after excavation. Polyethylene pipe system should be flexible and able to weld properties, especially for adopt
