聚氨酯保溫鋼管工藝
Polyurethane Insulation Pipe Technology
隨著整個(gè)生態(tài)環(huán)境要求的不時(shí)進(jìn)步，國(guó)度對(duì)整個(gè)社會(huì)開展環(huán)境維護(hù)的要求越來越高，對(duì)以鋼鐵爲(wèi)代表的工業(yè)范疇的要求就更高了。
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.
聚氨酯發(fā)泡保溫管比傳統(tǒng)保溫管運(yùn)轉(zhuǎn)顛簸，它能明顯降低動(dòng)力本錢。而且具有很強(qiáng)的防水和防腐蝕才能。耐沖擊性大，可間接埋上天下凍土，而且保證保溫管不會(huì)決裂。聚氨酯保溫管是目前*的保溫資料，它的運(yùn)用壽命極長(zhǎng)。經(jīng)多方實(shí)驗(yàn)認(rèn)證，聚氨酯保溫管的耐溫性、導(dǎo)熱系數(shù)、功能均到達(dá)目前*規(guī)范，是一種真正的保溫、耐腐蝕的高功能產(chǎn)品。聚氨酯保溫管具有其它保溫產(chǎn)品所無法比較的優(yōu)良功能，在城市熱力管道行業(yè)中發(fā)揚(yáng)了重要的作用。我管道直埋保溫管產(chǎn)品具有的特點(diǎn)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.用鋼管做外維護(hù)層，具有強(qiáng)度高。不易損壞且能接受較大上部荷載的特點(diǎn)，爲(wèi)到達(dá)短命命，對(duì)鋼外套管需停止防腐處置。
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.滾動(dòng)支持構(gòu)造設(shè)計(jì)合理，滾動(dòng)摩擦力小，固定支座受力減小，其力學(xué)剖析原理復(fù)雜，管道波動(dòng)性、平安性失掉較大進(jìn)步。預(yù)制直埋保溫管現(xiàn)場(chǎng)接頭保溫須在試壓合格前方可停止，現(xiàn)場(chǎng)接頭保溫施工。這一項(xiàng)內(nèi)容是預(yù)制直埋保溫管道施工特有的施工質(zhì)量好壞間接影響運(yùn)用壽命。保溫層有現(xiàn)場(chǎng)發(fā)泡施工和保溫瓦施工兩種辦法，不管采用哪種辦法施工，都不能呈現(xiàn)環(huán)形空間，開裂、脫層等缺陷，維護(hù)層的做法有多種(如高密度聚乙烯和玻璃鋼維護(hù)層)但都必需保證接頭的全體性，緊密性，防水性。聚氨酯保溫管起發(fā)速度慢此景象普通呈現(xiàn)在秋夏季節(jié)或晚上施工，由于氣溫忽然降低或氣溫低所致。環(huán)境溫度、黑料溫度降低即可處理。普通將黑料溫度升30-60℃，環(huán)境溫度升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.
化工管道鋼套鋼保溫鋼管接口處置技巧，鋼套鋼保溫鋼管防水功能要好。城市內(nèi)的地下管線非常復(fù)雜，特別是下水管線，漏水是罕見的景象，再有是雨水沉降，選用的直埋蒸汽管線*重要的一點(diǎn)就是便于處置外層的防水防腐，而塑套鋼復(fù)合保溫管外層是塑料套管，很好地處理了這個(gè)成績(jī)。直縫鋼管的雙絲自動(dòng)焊接是近幾年開展起來的焊接技術(shù)，它除了具有半自動(dòng)單絲焊接特點(diǎn)外，還具有能量集中、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.
