Abstract
The invention relates to a rigid polyurethane plastic foam insulation pipe and a machining method. A polyurethane insulation layer produced by an original polyurethane foaming technology is low in density, and polyurethane plastic foam is soft, has no supporting performance and is not resistant to high temperature. The rigid polyurethane plastic foam insulation pipe comprises a working pipeline, a rigid polyurethane plastic foam insulation layer and an outer protective pipeline, the rigid polyurethane plastic foam layer (2) is arranged outside the working pipeline (3), and the outer protective pipeline (1) is arranged at the outer side of the rigid polyurethane plastic foam layer. The rigid polyurethane plastic foam insulation pipe and the machining method are applied to the field of rigid polyurethane plastic foam insulation pipes.
Description
technical field:
the present invention relates to heat supply pipeline, cooling pipeline, petroleum and petrochemical industry conveyance conduit, boats and ships equal energy source conveyance conduit manufacture field, particularly a kind of hard polyaminoester plastic foam thermal insulation pipe and processing method.
background technique:
china is since early 1980s, introduction of foreign technology produced polyurethane foamed thermal-insulating pipe (being commonly called as black yellow jacket thermal insulation pipe), high speed development due to central heat supply cause has formed hundreds of manufacturer production enterprise, the phenomenon of low tender price over 30 years, cause pursuing low price strategy, low-quality must be brought at a low price, low-quality is inevitable short-lived, the inevitable highly energy-consuming of low-quality, so 30 Duo Nianlai China are after introducing industry technology, technology innovation is not only had to regenerate, stagnate on the contrary, manufacture in a rough and slipshod way, and quality of product operative norm is low, along with the development of real estate high speed geometry multiple in this year, energy energy consumption is caused to become multiple to increase, the haze bringing full Asia pollutes, be discord in people ' s health pole, reason is exactly due to factors, and not only thermal conductivity is high, water budget is lacked of proper care, the length of service is short to cause the black yellow jacket tube of domestic majority supply, and physical property is poor, thermal loss is large, maintenance expenses is many, therefore, quickening heating field technological innovation and technical innovation are the inevitable requirements of China's energy supply career development.
