聚氨酯保温钢管工艺
Polyurethane Insulation Pipe Technology
随着整个生态环境要求的不时进步,国度对整个社会开展环境维护的要求越来越高,对以钢铁爲代表的工业范畴的环保要求就更高了。
With the continuous progress of the requirements of the whole ecological environment, the country's requirements for environmental protection of the whole society are getting higher and higher, and the environmental protection requirements of the industrial category represented by iron and steel are even higher.
聚氨酯发泡保温管比传统保温管运转颠簸,它能明显降低动力本钱。而且具有很强的防水和防腐蚀才能。耐冲击性大,可间接埋上天下冻土,而且保证保温管不会决裂。聚氨酯保温管是目前*的保温资料,它的运用寿命极长。经多方实验认证,聚氨酯保温管的耐温性、导热系数、环保功能均到达目前国际*规范,是一种真正的保温、耐腐蚀的高功能产品。聚氨酯保温管具有其它保温产品所无法比较的优良功能,在城市热力管道行业中发扬了重要的作用。我管道直埋保温管产品具有的特点如下:
The polyurethane foamed insulating pipe runs more turbulently than the traditional insulating pipe, which can obviously reduce the power cost. And it has a strong ability of waterproof and anti-corrosion. High impact resistance, can be indirectly buried on the world's frozen soil, and ensure that the insulation pipe will not crack. Polyurethane insulating pipe is the current * insulation data, its service life is very long. It has been certified by many experiments that the thermal resistance, thermal conductivity and environmental protection of polyurethane insulating pipes have reached the current international * specifications. It is a high-functional product with real thermal insulation and corrosion resistance. Polyurethane insulating pipe has excellent functions that other insulating products can not compare, and plays an important role in the urban thermal pipeline industry. The characteristics of our direct buried insulation pipe products are as follows:
1.用钢管做外维护层,具有强度高。不易损坏且能接受较大上部荷载的特点,爲到达短命命,对钢外套管需停止防腐处置。
1. Using steel pipe as outer maintenance layer, it has high strength. It is not easy to be damaged and can accept larger upper load. In order to reach short life, it is necessary to stop anti-corrosion treatment of steel casing.
2.滚动支持构造设计合理,滚动摩擦力小,固定支座受力减小,其力学剖析原理复杂,管道波动性、平安性失掉较大进步。预制直埋保温管现场接头保温须在试压合格前方可停止,现场接头保温施工。这一项内容是预制直埋保温管道施工特有的施工质量好坏间接影响运用寿命。保温层有现场发泡施工和保温瓦施工两种办法,不管采用哪种办法施工,都不能呈现环形空间,开裂、脱层等缺陷,维护层的做法有多种(如高密度聚乙烯和玻璃钢维护层)但都必需保证接头的全体性,紧密性,防水性。聚氨酯保温管起发速度慢此景象普通呈现在秋夏季节或晚上施工,由于气温忽然降低或气温低所致。环境温度、黑料温度降低即可处理。普通将黑料温度升至30-60℃,环境温度升至20-30℃即可。
2. The design of rolling support structure is reasonable, the rolling friction is small, the force of fixed support is reduced, the mechanics analysis principle is complex, and the fluctuation and safety of pipeline are greatly improved. The field joint insulation of prefabricated directly buried insulating pipes should be stopped before the qualified pressure test, and the field joint insulation construction should be carried out. This content is that the construction quality of prefabricated directly buried insulation pipeline has indirect influence on its service life. Thermal insulation layer has two methods: field foaming construction and thermal insulation tile construction. No matter which method is adopted, it can not present annular space, cracking, delamination and other defects. There are many methods of maintenance layer (such as high density polyethylene and fiberglass reinforced plastic maintenance layer), but it is necessary to ensure the integrity, tightness and waterproofing of joints. Polyurethane insulation pipes start slowly. This phenomenon usually appears in autumn and summer or night construction, due to the sudden drop in temperature or low temperature. The environmental temperature and black material temperature can be reduced. Usually, the temperature of black material is raised to 30-60 C, and the ambient temperature is raised to 20-30 C.

化工管道钢套钢保温钢管接口处置技巧,钢套钢保温钢管防水功能要好。城市内的地下管线非常复杂,特别是下水管线,漏水是罕见的景象,再有是雨水沉降,选用的直埋蒸汽管线*重要的一点就是便于处置外层的防水防腐,而塑套钢复合保温管外层是塑料套管,很好地处理了这个成绩。直缝钢管的双丝自动焊接是近几年开展起来的先进焊接技术,它除了具有半自动单丝焊接特点外,还具有能量集中、熔敷效率初等焊接特性。
The waterproofing function of steel-jacketed insulating steel pipe in chemical pipeline is better than that of steel-jacketed insulating steel pipe. Underground pipelines in cities are very complex, especially sewer pipelines. Leakage is a rare phenomenon, and rainwater settlement. The important point of directly buried steam pipelines is to facilitate the disposal of waterproof and anti-corrosion of the outer layer. The outer layer of plastic-coated steel composite insulation pipe is plastic casing, which handles this achievement well. Double wire automatic welding of straight seam steel pipe is an advanced welding technology developed in recent years. It not only has the characteristics of semi-automatic single wire welding, but also has the primary welding characteristics of energy concentration and depositing efficiency.
