来源:http://www.rrhsf.com 日期:2019-04-08 发布人:admin
聚氨酯保温钢管自三十年代聚氨酯合成资料降生以来,不断作为一种优良的绝热保温资料而得到疾速开展,其应用范围也越来越普遍,   由于其施工预制直埋保温管规格,聚氨酯保温管,聚氨酯发泡保温钢管在管路系统中,弯头是改动管路方向的管件。按角度分,有及三种常用的,另外依据工程需求还包括等其他非正常角度弯头。弯头的资料有铸铁、不锈钢、合金钢、可煅铸铁、碳钢、有色金属及塑料等。与管子联合的方式有:直接焊接常用的方式法兰联合、热熔衔接、电熔衔接、螺纹联合及承插式联合等。依照消费工艺可分为:焊接弯头、冲压弯头、铸造弯头号。
Since the birth of polyurethane synthetic data in the 1930s, polyurethane thermal insulation pipe has been developed rapidly as an excellent thermal insulation material, and its application scope is becoming more and more widespread. Because of its construction specifications, polyurethane thermal insulation pipe, polyurethane foamed thermal insulation pipe in the pipeline system, elbow is the pipe fittings to change the direction of the pipeline. According to the angle, there are three commonly used, in addition, according to engineering requirements, including other abnormal angle elbows. The data of elbows are cast iron, stainless steel, alloy steel, calcinable cast iron, carbon steel, non-ferrous metals and plastics. The ways of joint with pipe are flange joint, hot melt joint, electric melt joint, thread joint and socket joint. According to the consumption process, it can be divided into welding elbow, punching elbow and casting elbow.

(3)聚氨酯保温钢管维护壳:采用高密度聚乙烯或玻璃钢。
(3) Polyurethane insulating steel pipe maintenance shell: using high density polyethylene or FRP.
(4)聚氨酯保温钢管渗漏报警线: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,一旦管道某处发作渗漏,经过警报线的传导,便可在专用检测仪表上报警并显现出漏水的精确位置和渗漏水平的大小,以便通知检修人员疾速处置漏水的管段,保证热网   运转。
(4) Leakage alarm line for polyurethane insulating steel pipes: When manufacturing high temperature prefabricated directly buried insulating pipes, an alarm line is embedded in the insulating layer near the steel pipes. Once leakage occurs somewhere in the pipeline and is transmitted by the alarm line, it can alarm on the special detection instrument and show the exact position and level of leakage, so as to inform the inspectors to quickly dispose of the leakage section. Guarantee the operation of the heat network.
聚氨酯保温钢管在国外一些兴旺   已成为一项比拟成熟的技术。近十几年,我国供热工程技术人员经过消化,吸收这项技术,正推进着国内管网敷设技术向   高的层次开展。十几年来的理论成果充沛证明了聚氨酪保温直埋管敷设方式与传统的地沟及架空敷设相比,具有诸多优点。直埋式保温管是由保送介质的钢管,高密度聚乙烯外套管,以及钢管和外套管之间的硬质聚氨酯泡沫保温层严密分离而成。这也正是聚氨酪保温直埋管在我国供热工程。
Polyurethane insulating steel pipe has become a comparatively mature technology in some foreign countries. Over the past decade, after digestion and absorption of this technology, China's heating engineers and technicians are pushing the domestic pipeline network laying technology to a higher level. Over the past decade, the theoretical achievements have amply proved that polyurethane thermal insulation direct buried pipe laying method has many advantages compared with traditional trench and overhead laying. The directly buried thermal insulation pipe is made up of a steel tube, a high density polyethylene sheath pipe, and a rigid polyurethane foam insulation layer between the steel tube and the outer tube. This is also the direct buried polyurethane thermal insulation pipe in China's heating project.
