　　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.

　　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. The polyurethane rigid foam has a continuous and dense skin and nearly 100% high-strength interconnected wall 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 pipe is divided into three layers from inside to outside

　　Layer: The working steel pipe layer generally uses seamless pipes (GB8163-87), spiral welded pipes (GB9711-88; SY/T5038-92), and straight seam welded pipes (GB3092-93) according to the design and customer requirements. After advanced shot blasting and rust removal process, the rust removal grade of the steel pipe can reach Sa2 level in GB8923-1988 standard, and the surface roughness can reach R=12.5 microns in GB6060.5-88 standard

　　Second layer: the polyurethane insulation layer is made by injecting the original liquid of rigid polyurethane foam into the cavity formed between the steel pipe and the outer protective layer with a high-pressure foaming machine at one time. It is commonly known as the "pipe in pipe foaming process". Its functions include waterproofing, insulation, and supporting the self weight of the heating network. When the temperature of the conveying medium is -50120, rigid polyurethane foam is selected as the insulation layer.

　　Third layer: The high-density polyethylene protective layer is prefabricated into black (yellow) plastic pipes with a certain wall thickness, which serves to protect the polyurethane insulation layer from mechanical hard objects and prevent corrosion and waterproofing

　　Product structure form: Prefabricated buried steam insulation pipe consists of core tube (working steel pipe) rent reduction layer, insulation layer, reflection layer, fastening steel strip, sliding bracket, air layer, outer protective steel pipe, sprayed polyurethane, and wrapped fiberglass.

　　Black jacket polyurethane foam insulation pipe foam has good mechanical properties and thermal insulation polyurethane insulation pipe application: polyurethane insulation pipe is used for indoor and outdoor pipes, central heating pipes, central air conditioning pipes, chemical, and other industrial pipe insulation and cold insulation projects. Overview: Polyurethane foam insulation pipe has been rapidly developed as an excellent insulation material since the birth of polyurethane synthetic materials in the 1930s. Its application scope is also becoming more and more extensive. Due to its simple construction and significant energy-saving and anti-corrosion effects, it is widely used in various pipelines such as heating, cooling, oil transportation, and steam transportation. Widely used in various pipelines for heating, cooling, oil transportation, steam transportation, etc.
