Factory direct sales of large-diameter polyurethane insulated steel pipes, directly buried insulated pipes, and centralized heating insulated pipes

Description :

　　Polyurethane direct buried insulation pipe is a type of prefabricated insulation pipe with good insulation performance, safety and reliability, and low engineering cost.

　　Directly buried insulation pipes not only have advanced technology and practical performance that traditional trench and overhead pipelines cannot match, but also have significant social and economic benefits, and are also powerful measures for heating energy conservation.

　　The use of prefabricated buried insulation pipes with direct buried heating pipeline technology marks a new starting point in the development of China's heating pipeline technology. With the decreasing global energy and increasing demand, energy conservation, emission reduction, and environmental protection have become global development trends. Countries and regions also vigorously promote the development, application, and industrialization of energy-saving, emission reduction, and environmentally friendly products. Polyurethane rigid foam insulation materials used in the construction industry are an important branch of the polyurethane industry, characterized by their versatility and the ability to provide insulation, waterproofing, and other functions. This type of product has a history of 40 years since its application in the European construction industry in the 1960s, and some countries have also legislated polyurethane as a designated insulation and waterproofing material for the construction industry. In recent years, with the rapid development of China's building energy-saving market, polyurethane rigid foam insulation products have been widely used in the field of building insulation and waterproofing, and have become one of the leading insulation and energy-saving products in the market.

　　As an integrated material for building insulation and waterproofing, polyurethane rigid foam breaks the traditional building materials' single function of waterproofing without insulation and insulation without waterproofing. Once the waterproof layer leaks, the insulation layer immediately loses its insulation function. Compared with other single function insulation or waterproof materials, polyurethane rigid foam has significant advantages:

　　1. Polyurethane rigid foam has multiple functions as a single material, as well as insulation, waterproofing, sound insulation, vibration absorption and many other functions.

　　2. Thermal insulation performance, it is currently the insulation material with a thermal conductivity coefficient (0.024) and thermal resistance value among all building materials in China, with a thermal conductivity coefficient only half of EPS foam polystyrene board.

　　3. Polyurethane rigid foam has a continuous and dense skin and nearly high-strength interconnected walls with closed pores, which have ideal impermeability. The spraying method is used for construction to achieve a continuous and seamless waterproof insulation layer, forming a seamless roof and overall external wall insulation shell, with excellent waterproof and anti-seepage performance.

　　4. Superb self-adhesive performance (without the need for any intermediate bonding materials), firmly bonded to roofs and exterior walls, with good wind resistance and resistance to negative wind pressure; Whole spray coating construction, completely eliminating "hot spots" and "cold bridges"; Flexible gradient technology can effectively prevent cracking of the waterproof layer; Mechanized operation, automatic batching, uniform quality, fast construction, and short cycle.

　　5. Stable chemical properties, long service life, and no pollution to the surrounding environment; It extinguishes itself from an open flame and only carbonizes without dripping during combustion. The size and shape of the carbonization layer remain basically unchanged, effectively blocking the entry of air and preventing the spread of fire, with good fire safety performance.

　　As a new type of integrated building material for insulation and waterproofing, the application of polyurethane rigid foam insulation materials in the domestic construction industry is still in its initial stage. Fortunately, in order to accelerate the innovation of building insulation materials and promote the promotion and application of polyurethane rigid foam in the field of building energy conservation, the Ministry of Construction has specially established the "Polyurethane Building Energy Conservation Application Working Group" to promote the application of polyurethane rigid foam insulation and waterproof materials in the domestic building energy conservation industry.

　　Polyurethane insulation pipes have excellent characteristics such as light bulk density, high strength, thermal insulation, sound insulation, flame retardancy, cold resistance, corrosion resistance, non water absorption, and easy and fast construction. They have become indispensable materials for insulation, waterproofing, sealing, and other industrial sectors such as construction, transportation, petroleum, chemical, power, and refrigeration.
