PRODUCT INTRODUCTION
For the pipe corridor overhead insulation pipe is in the overhead open air state for a long time, the original PE outer protection pipe is not suitable for this kind of environment due to the deviation of its ability to resist ultraviolet radiation, so the overhead polyurethane galvanized hot water heat preservation pipe products came into being.The product uses galvanized steel coil as the outer protection pipe of the insulation pipe instead of PE, which gives play to the advantages of galvanized sheet in rust resistance, oxidation resistance and ultraviolet radiation resistance, etc. Meanwhile, the galvanized outer protection pipe with polyurethane insulation and the inner working steel pipe are in one piece, so that the characteristics of heat preservation, protection and aesthetics can be brought into full play.In addition, due to the generally low price of domestic steel, the galvanized outer protection is also far better than PE outer protection pipe in terms of cost.Therefore, the overhead polyurethane galvanized hot water heat preservation pipe is favored by many users, producers and designers.
PRODUCT CHARACTERISTICS
● Have the advantages of a one-piece direct buried insulated pipe;
● Good thermal insulation performance, heat loss of only 25% of the traditional pipe, 40km long-distance transmission temperature drop of no more than 1 ℃.
● Waterproof, corrosion-resistant, harsh environments can be guaranteed in the outdoors for 30 years to visualize no corrosion changes in the outer tube;
● Long service life, up to 30-50 years;
● An alarm system can be set up;
● The construction is easy and quick, avoiding the complexity of work such as hot-melt patching;
● Strong fit, fundamentally different from post-twisted galvanized iron protection.Completely fit, the trinity structure has a long service life and is not easy to damage;
● Material cost advantage, the unit price of galvanized steel is 30% -50% of PE material.
● Advantageous material consumption, hardness, mechanical strength and other requirements of the same indicators from the point of view of the amount of reduction of about 50%;.
● Production and processing advantages.Processes and speeds are far superior to those of PE extrusion, and energy consumption is low;
● Aesthetic advantage, the appearance of the beautiful and elegant silver, can be customized color;
● Combined with the use of the environment, you can choose our special flame retardant B1 grade PU.
