如果使用了很长时间,管道的弯头或关节将承担太多的压力,导致管道破裂,从而减少聚氨酯保温管的使用寿命。高密度聚乙烯绝缘管的应用:适用于输送各种媒体在-50℃150℃保温和冷却工程。安装和使用硬质聚氨酯保温管，可适用于城市供热、电加热、水与保温、输油管道等直埋工程，维护费用极低。施工边界是聚氨酯保温管常用的应用边界。铜管又称铜管，有色金属管是一种无缝钢管。为了防止铸铁板变形，在吊装铸铁板时，应同时用四根长度相同的钢索将四个吊孔吊在铸铁板上。
If it is used for a long time, the elbow or joint of the pipe will bear too much pressure, resulting in pipe rupture, thus reducing the service life of polyurethane insulation pipe. Application of HDPE insulated pipe: it is suitable for conveying all kinds of media in - 50 ℃ and 150 ℃ insulation and cooling engineering. The installation and use of rigid polyurethane insulation pipe can be applied to urban heating, electric heating, water and insulation, oil pipeline and other direct buried projects, with very low maintenance costs. Construction boundary is the common application boundary of polyurethane insulation pipe. Copper pipe, also known as copper pipe, non-ferrous metal pipe is a seamless steel pipe. In order to prevent the cast iron plate from deforming, four lifting holes shall be hung on the cast iron plate with four steel cables of the same length.
在绝缘材料中，外壳的导热系数很低，从而使材料的热损失更小化。聚氨酯外壳在制造过程中是一个保护处理，所以它是非常有效的，使用时不会损坏内芯。内外滑动钢衬套钢蒸汽绝缘故障:高的薄壁不锈钢管,壁厚为0.6 0毫米不锈钢带或不锈钢板通过焊接过程,如自动氩弧焊是由不锈钢管由于其、健康、高强度、耐腐蚀性能好,耐用,使用寿命长,维护自由、美丽的外表,等发展,广泛应用于建筑供水和直接饮用水管道。既能隔离绝缘，又能有效防止水、湿气等腐蚀性液体和气体。有效了130 ~ 600℃高温传热用预制直埋保温管的保温、滑动润滑、防水等问题。直埋保温管应用领域直埋保温管冷热水管道在城市建设给排水系统中的应用领域
In insulating materials, the thermal conductivity of the shell is very low, so that the heat loss of the material is minimized. Polyurethane shell is a protective treatment in the manufacturing process, so it is very effective and will not damage the inner core when used. Internal and external sliding steel lining steel steam insulation failure: high price thin-walled stainless steel pipe with a wall thickness of 0.60mm stainless steel belt or stainless steel plate through the welding process. For example, automatic argon arc welding is developed by stainless steel pipe due to its safety, health, high strength, good corrosion resistance, durability, long service life, free and beautiful appearance maintenance, etc, It is widely used in building water supply and direct drinking water pipeline. It can not only isolate insulation, but also effectively prevent water, moisture and other corrosive liquids and gases. The problems of heat preservation, sliding lubrication and water proofing of the prefabricated directly buried heat preservation pipe for high temperature heat transfer at 130 ~ 600 ℃ are effectively solved. Application field of directly buried heat preservation pipe application field of directly buried heat preservation pipe cold and hot water pipe in urban construction water supply and drainage system
钢管的表面质量应光滑，不得有折叠、开裂、分层、搭接等缺陷。住宅和办公楼给排水系统用冷热水管;液化气、燃气等管道;石油、天然气、腐蚀液、食品、医药等液体输送管道。与普通介质相比，大家都认为输出介质通常是冷水、热水等。在安装铸铁聚氨酯保温管平台时，铸铁板各支撑点应做好缓冲，并用调节垫垫好。技术人员应将铸铁板调整到合格的精度。轻质不锈钢管具有以下突出优点:机械性能优良，耐磨性好，卫生性能好，耐高温，隔热性能好，内壁光滑，耐水性差;外观美观、干净、时尚、可回收利用;有利于节约水资源;广泛使用;镀锌钢管使用寿命长，成本低，镀锌钢管分为冷镀锌管和热镀锌管。钢管表面允许有不超过壁厚的负偏差的划痕、焊缝错位、烧伤和瘢痕等轻微缺陷。它具有、、防腐、保温、防冻、耐寒、经济美观等优点。
The surface quality of the steel pipe shall be smooth and free from defects such as folding, cracking, layering and overlapping. Cold and hot water pipes for water supply and drainage system of residential and office buildings; liquefied gas, gas and other pipelines; oil, natural gas, corrosive liquid, food, medicine and other liquid transmission pipelines. Compared with ordinary media, we all think that the output media is usually cold water, hot water, etc. When installing the cast-iron polyurethane insulation pipe platform, the supporting points of the cast-iron plate shall be well cushioned and well padded with adjusting pads. The professional technician shall adjust the cast iron plate to the qualified accuracy. Light stainless steel pipe has the following outstanding advantages: excellent mechanical performance, good wear resistance, good safety and health performance, high temperature resistance, good heat insulation performance, smooth inner wall, poor water resistance; beautiful appearance, clean, fashionable, recyclable; conducive to saving water resources; widely used; galvanized steel pipe has long service life and low cost, galvanized steel pipe is divided into cold galvanized pipe and hot galvanized pipe. The steel pipe surface is allowed to have minor defects such as scratch, weld dislocation, burn and scar with negative deviation not exceeding the wall thickness. It has the advantages of environmental protection, energy saving, anticorrosion, heat preservation, antifreeze, cold resistance, economic beauty, etc.
