Daily water burial insulation pipe medium temperature
Buried thermal insulation pipe has high-performance insulation, waterproof, corrosion, insulation, sound insulation, flame retardant, cold-resistant, anti-corrosion, light capacity, high strength, simple and convenient construction, not afraid of plant stings and other outstanding features, has become a construction, transportation, petroleum, chemical , electricity, refrigeration and other industrial sectors insulation insulation, waterproof plugging, sealing, etc. can not be deficient information. Buried thermal insulation pipes are used for indoor and outdoor pipes, centralized heating pipes, central air-conditioning pipes, chemical, pharmaceutical and other industrial pipe insulation, cold insulation engineering, oil pipeline engineering, and gas pipelines. The buried insulation pipe has been rapidly developed as an excellent thermal insulation material since the birth of the polyurethane composition data in the 1930s. The scale of its use has become more and more extensive. It is also because of its simple construction and obvious energy-saving and anti-corrosion effects.
Buried thermal insulation pipe is widely used in liquid and gas transportation pipe network, chemical pipeline insulation engineering petroleum, chemical industry, central heating and heating network, central air-conditioning ventilation pipe, municipal engineering and so on. Buried insulation pipe is a direct-buried prefabricated insulation pipe with good insulation function, safety and reliability, and low construction cost. Buried thermal insulation pipe not only has the advanced skills and useful functions that are difficult to compare with conventional trenches and overhead laying pipelines, but also has obvious social and economic benefits, and is also a powerful method for heating and energy saving. The pre-prepared direct-buried thermal insulation pipe uses the skill of directly burying the heating pipeline, which indicates that the development of China's heating pipeline technology has now entered a new starting point.
