如果使用了很長時間,管道的彎頭或關(guān)節(jié)將承擔太多的壓力,導致管道破裂,從而減少聚氨酯保溫管的使用壽命。高密度聚乙烯絕緣管的應用:適用于輸送各種媒體在-50℃150℃保溫和冷卻工程。安裝和使用硬質(zhì)聚氨酯保溫管，可適用于城市供熱、電加熱、水與保溫、輸油管道等直埋工程，維護費用極低。施工邊界是聚氨酯保溫管常用的應用邊界。銅管又稱銅管，有色金屬管是一種無縫鋼管。為了防止鑄鐵板變形，在吊裝鑄鐵板時，應同時用四根長度相同的鋼索將四個吊孔吊在鑄鐵板上。
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.
在絕緣材料中，外殼的導熱系數(shù)很低，從而使材料的熱損失更小化。聚氨酯外殼在制造過程中是一個保護處理，所以它是非常有效的，使用時不會損壞內(nèi)芯。內(nèi)外滑動鋼襯套鋼蒸汽絕緣故障:高的薄壁不銹鋼管,壁厚為0.6 0毫米不銹鋼帶或不銹鋼板通過焊接過程,如自動氬弧焊是由不銹鋼管由于其、健康、高強度、耐腐蝕性能好,耐用,使用壽命長,維護自由、美麗的外表,等發(fā)展,廣泛應用于建筑供水和直接飲用水管道。既能隔離絕緣，又能有效防止水、濕氣等腐蝕性液體和氣體。有效了130 ~ 600℃高溫傳熱用預制直埋保溫管的保溫、滑動潤滑、防水等問題。直埋保溫管應用領(lǐng)域直埋保溫管冷熱水管道在城市建設(shè)給排水系統(tǒng)中的應用領(lǐng)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
鋼管的表面質(zhì)量應光滑，不得有折疊、開裂、分層、搭接等缺陷。住宅和辦公樓給排水系統(tǒng)用冷熱水管;液化氣、燃氣等管道;石油、天然氣、腐蝕液、食品、醫(yī)藥等液體輸送管道。與普通介質(zhì)相比，大家都認為輸出介質(zhì)通常是冷水、熱水等。在安裝鑄鐵聚氨酯保溫管平臺時，鑄鐵板各支撐點應做好緩沖，并用調(diào)節(jié)墊墊好。技術(shù)人員應將鑄鐵板調(diào)整到合格的精度。輕質(zhì)不銹鋼管具有以下突出優(yōu)點:機械性能優(yōu)良，耐磨性好，衛(wèi)生性能好，耐高溫，隔熱性能好，內(nèi)壁光滑，耐水性差;外觀美觀、干凈、時尚、可回收利用;有利于節(jié)約水資源;廣泛使用;鍍鋅鋼管使用壽命長，成本低，鍍鋅鋼管分為冷鍍鋅管和熱鍍鋅管。鋼管表面允許有不超過壁厚的負偏差的劃痕、焊縫錯位、燒傷和瘢痕等輕微缺陷。它具有、、防腐、保溫、防凍、耐寒、經(jīng)濟美觀等優(yōu)點。
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.
