Buried steel jacket pipe insulation manufacturers supply / latest offer

Prefabricated buried pipe insulation characteristics: heat pipe is made of prefabricated steel, glass steel jacket, fiberglass shell structure, characterized by: further comprising a heat insulation layer, a lubricating layer, elastomeric seals. The utility model prefabricated pipe insulation effectively solve urban central heating in 130 ℃ -600 ℃ high temperature heat transport with prefabricated buried pipe insulation / prefabricated insulating pipe insulation, sliding lubrication and waterproofing exposed pipe ends. Buried polyurethane insulation is a good insulation properties, plus safe, reliable, low construction cost of prefabricated buried pipe insulation. Buried polyurethane insulation tubes only traditional trench and overhead laying pipeline incomparable advanced technology, practical performance, but also has significant social and economic benefits, but also a powerful heating energy-saving measures. Buried polyurethane insulation technology using buried heating pipe, heating pipe technology development indicates that China has entered a new starting point. With the growing world energy demand and dwindling, energy saving, emission reduction, environmental protection has become the trend of global development, state and local governments to vigorously promote energy conservation, emission reduction, the development of environmentally friendly products, applications and industry, construction industry Polyurethane Rigid Foam insulation materials is an important branch of the polyurethane industry, which is characterized by a multi-purpose timber, along with insulation, water and other functions. These products since the 1960s in Europe since the construction industry applications for more than 40 years, some countries have adopted legislation to polyurethane as insulation waterproof construction specified timber. In recent years, with the rapid development of China's building energy efficiency market, the polyurethane foam insulation products in building insulation body waterproofing has been widely used, has become one of the thermal insulation products dominate the market. Waterproof materials as building insulation, polyurethane foam breaking the traditional function of a single building materials - not waterproof insulation, thermal insulation is not waterproof, waterproof layer insulation leakage occurs once a common problem immediately lose insulation function. Compared with other single-function insulation or waterproofing material, polyurethane foam has obvious advantages: 1. Polyurethane foam material having a multi-function, along with insulation, water, noise, vibration absorption and many other features. 2. Insulation performance, is all the domestic building materials lowest thermal conductivity (≤0.024), the highest heat resistance of insulation materials, thermal conductivity is only half of EPS foam polystyrene board. 3. Polyurethane Rigid Foam in continuous dense skin and nearly 100% of the high intensity Internet wall closed cells having the desired impermeability. Spraying construction method to achieve continuous seamless waterproof insulation layer, to form a seamless whole roof and wall insulation housing, excellent water impermeability. 4. super sticky performance (without any intermediate adhesive material), and the roof and exterior wall bonding firm, exposing and anti-wind pressure negative good performance; overall spraying construction, completely eliminate the "hot spot" and "cold bridge" ; flexible gradient technology can effectively prevent the waterproof layer cracking; mechanized operations, automatic batching, uniform quality, construction of fast, short cycle. 5. The chemical stability, long life, does not constitute pollution on the surrounding environment; from the fire self-extinguishing, and only when burning charring not dripping, carbonized layer is essentially the same size and shape, can effectively cut off the entry of air to prevent the fire spread, fire safety performance. As the only insulation and waterproof integration of new materials, polyurethane foam insulation material in the domestic construction industry is still in the initial stages of application. The good news is, in order to accelerate the innovation of building insulation materials, promote the popularization and application of polyurethane foam in building energy saving field, the Ministry of Construction set up a "promote the application of polyurethane building energy efficiency working group" in order to promote the polyurethane foam insulation waterproof material in the domestic construction energy industry applications. Polyurethane insulation buried pipe in some foreign countries has become a relatively mature and advanced technology. Over the last decade, our heating engineering and technical personnel through the digestion and absorption of this advanced technology is driving the domestic pipeline laying technology to a higher level. 10 years of practical results fully proved casein polyurethane insulation buried pipe laying method compared with the traditional trench and laying of overhead, it has many advantages. Buried pipe insulation is made of steel transmission medium, high density polyethylene outer tube, and rigid polyurethane foam insulation pipe and the jacket pipe closely together.
