(2)保温层:采用硬质聚氨酯泡沫塑料。(3)保护壳:采用高密度聚乙烯或玻璃钢。(4)渗漏报警线:制造高温预制直埋保温管时,在靠近钢管的保温层中,埋设有报警线,一旦管道某处发生渗漏,通过线的传导,便可在专用检测仪表上报警并显示出漏水的准确位置和渗漏程度的大小,以便通知检修人员迅速处理漏水的管段,保证热网安全运行。防腐,绝缘性能好,使用寿命长。除中国外生产的高温预制直埋保温管,均设有渗漏报警线,一旦管道某处发生渗漏,通过报警线的传导,便可在专用检测仪表上显示出保温管道渗水、漏水的准确位置及渗漏程度的大小,以便通知检渗人员迅速处理漏水的管段,保证供热管网的安全运行,国内报警线,有待补上这一空之。
(2) insulation layer: rigid polyurethane foam. (3) Protective shell: high density polyethylene or glass fiber reinforced plastic. (4) Leakage alarm line: when manufacturing high-temperature prefabricated directly buried insulation pipe, there is an alarm line embedded in the insulation layer close to the steel pipe. Once there is leakage in the pipeline, through the transmission of the line, the alarm can be given on the special detection instrument, and the accurate position and degree of leakage can be displayed, so as to inform the maintenance personnel to deal with the leaking pipe section quickly and ensure the safe operation of the heat supply network. Anticorrosion, good insulation and long service life. Except for the high-temperature prefabricated directly buried insulation pipes produced outside China, leakage alarm lines are set. Once there is leakage in the pipeline, through the conduction of the alarm line, the accurate position and degree of leakage of the insulation pipeline can be displayed on the special detection instrument, so as to inform the leakage inspection personnel to quickly deal with the leaking pipe section, ensure the safe operation of the heating pipe network, and give an alarm at home The line needs to be filled.
国标黑夹克保温管选用尺寸,预制聚氨酯保温钢管由工作钢管、硬质聚氨酯发泡泡沫塑料保温层和高密度聚外护管组成。聚氨酯发泡产品广泛应用于城市集中供热和制冷工程,节能效果显著,施工安装方便,具有良好的经济效益和社会效益预制聚氨酯保温钢管的结构预制聚氨酯保温钢管主要由三部分组成。
黑夹克直埋式直缝钢管
The national standard black jacket thermal insulation pipe is selected in size, and the precast polyurethane heat preservation steel pipe is composed of a working steel pipe, a rigid polyurethane foam foam insulation layer and a high-density external protective pipe. Polyurethane foam products are widely used in urban central heating and cooling engineering, with remarkable energy saving effect, convenient construction and installation, and good economic and social benefits. The structure of prefabricated polyurethane insulation steel pipe is mainly composed of three parts.
层:工作钢管层。根据输送介质的技术要求分别采用有缝钢管、无缝钢管、双面埋弧螺旋焊接钢管第二层:聚氨酯保温层。用高压发泡机在钢管与外护层之间形成的空腔中一次性注入硬质聚氨酯泡沫塑料原液而成,即俗称的“管中管发泡”第三层:高密度聚保护层。 由于涂敷内涂层时,钢管的加热温度必须在所使用熔结环氧粉末涂料所要求的温度范围内,但高温度不得超过275℃。该作业线设计防腐生产规格为 φ60mm~φ426mm的钢管,选择中频功率时,通过计算我们选择使用的中频功率为250kw,并选用了多圈单闸中频感应圈,在试运行中用远红外测温仪对钢管温度进行测量,发现使用多圈单闸中频感应圈存在一定的缺点,钢管局部温度过高或高低,使钢管加热温度不匀,影响内防腐。,8、以求生存,以求发展,向要效益,环氧白陶瓷防腐螺旋钢管厂家了市场,房地产投资93387亿元,即可进行涂装。
Layer: working steel pipe layer. According to the technical requirements of conveying medium, seamless steel pipe, seamless steel pipe and double-sided submerged arc spiral welded steel pipe are used respectively. The second layer: polyurethane insulation layer. The rigid polyurethane foam plastic is injected into the cavity formed between the steel pipe and the outer sheath by high-pressure foaming machine. The third layer is commonly called "tube in tube foaming": high density protective layer. As the internal coating is applied, the heating temperature of the steel pipe must be within the temperature range required by the fusion bonded epoxy powder coating used, but the high temperature shall not exceed 275 ℃. The design anticorrosion production specification of the operation line is When the medium frequency power is selected for the steel pipe with the diameter of 60mm ~ 426mm, the medium frequency power of 250KW is selected by calculation. In the trial operation, the temperature of the steel pipe is measured by the far-infrared thermometer. It is found that there are some shortcomings in using the multi circle single switch medium frequency induction coil. The local temperature of the steel pipe is too high or high, which makes the heating temperature of the steel pipe uneven Internal corrosion protection. In order to survive, develop and benefit, the manufacturer of epoxy white ceramic anti-corrosion spiral steel pipe has entered the market and invested 9338.7 billion yuan in real estate, which can be used for coating.
黑夹克保温管施工工艺聚氨酯发泡由双组份组成,施工时两组份进入喷涂机械中混合喷出,呈雾状,一分钟发泡凝固成型,这种材料近几年才引进,用于建筑保温防水,经过三年的使用,对它有了较多的了解,优点很多,使用范围很广。-、施工时应避免地下水及雨水的浸泡,若端头不慎浸水,连接外套前应做干燥处理。
The construction technology of black jacket insulation pipe polyurethane foam is composed of two components. During the construction, the two components enter the spraying machinery and mix and spray out, which is in the form of fog. It is foamed and solidified in one minute. This kind of material was introduced in recent years and used for building thermal insulation and waterproof. After three years of use, it has more understanding, advantages and wide application range. -During construction, the immersion of underground water and rain water shall be avoided. If the end is accidentally immersed in water, drying treatment shall be carried out before connecting the jacket.
-、管材应储存在平整的场地,整齐码放,码放高度应小于-.-米。-、管材吊装在轻装轻放,禁碰撞、抛掷,禁用钢丝绳直吊管身。-、保温层及防腐层应避免火焰直接接触。管沟开挖--基底处理排水、垫砂-下管--钢管焊接-检验水压-安装试压-发泡-封发泡孔。我公司可以派遣人员到工程现场进行接头的保温工作,包括接头外套管的安装、接头外套管与主管的连接和密封以及现场接头的发泡工作。
-The pipes should be stored in a flat site and stacked in order, and the stacking height should be less than -. - M. -Pipe hoisting should be carried out with care, collision and throwing are prohibited, and steel wire rope is not allowed to directly lift the pipe body. -Thermal insulation layer and anti-corrosion coating shall avoid direct contact with flame. Pipe trench excavation base treatment drainage, sand bedding - pipe laying - steel pipe welding - water pressure test - installation and pressure test - foaming - sealing of foam holes. Our company can send personnel to the project site to carry out the joint insulation work, including the installation of the joint outer sleeve, the connection and sealing of the joint sleeve and the main pipe, and the foaming work of the joint on site.
