There are two main types of thermal insulation structures for prefabricated thermal insulation directly buried steam pipes made of steel jacket: composite thermal insulation structure (ie, tile foam rigid thermal insulation structure or internal sliding) and single thermal insulation structure (ie soft thermal insulation structure or external sliding) The steel jacket prefabricated thermal insulation direct buried steam pipeline (composite thermal insulation structure) uses microporous calcium silicate thermal insulation tile for the inner layer and polyurethane foam for the outer layer. Calculated at an ambient temperature of 20 °C, the surface temperature of the outer protective steel pipe is not greater than 50 °C. Conveying medium: steam, hot water

The inner layer of the prefabricated overhead thermal insulation steam pipeline (composite thermal insulation structure) adopts microporous calcium silicate thermal insulation tile, and the outer layer adopts polyurethane foam, and the surface temperature is controlled at 2-3°C higher than the ambient temperature. The outer protective tube can be made of aluminum alloy, color steel plate and other materials. Conveying medium: steam, hot water

HUWIP series prefabricated direct-buried polyurethane thermal insulation pipe is a composite thermal insulation pipe composed of high-density polyethylene outer protective pipe, polyurethane rigid foam plastic thermal insulation layer and working pipe using the factory prefabricated production process, and is installed in the ground. Transport medium: heating hot water, cooling water, central air conditioning supply and return water, high viscosity crude oil, heavy oil, etc.

HAWIP series prefabricated overhead polyurethane thermal insulation pipes are prefabricated in factories, and are composite thermal insulation pipes composed of rolled metal sheath pipes, polyurethane rigid foam thermal insulation layers and working pipes, and are installed overhead. Transport medium: heating hot water, cooling water, central air conditioning supply and return water, high viscosity crude oil, heavy oil, etc.

The heat supply network is responsible for transporting heat to the building. The less heat is lost during transmission, the more efficient the network is and the less energy is wasted. In the energy-saving renovation of the heating pipe network, it is necessary to select high-efficiency thermal insulation materials with low thermal conductivity, large moisture resistance factor, low water absorption rate, and low density, which can reduce the heat exchange between the pipe network and the surrounding environment, and reduce the heat of the pipe network. loss. Our company has carried out on-line transformation of the heating network with a soft thermal insulation structure, and measures to improve efficiency and energy saving have eliminated the defect that the soft thermal insulation pipe network requires frequent maintenance and overhaul.

Among many owners, heat production is a common operation demand, but the heating management cannot be refined, and the owners are also deeply troubled by the problem of large energy waste. Relying on our own technical and engineering experience, our company has a deep understanding and maintenance experience in heat supply management, which can help the owners share their worries and difficulties.

Entrusted by the owner, the whole process or several stages of contracting for the design, procurement, construction and trial operation of the heating network construction project are carried out in accordance with the contract. Usually the company is responsible for the quality, safety, cost and progress of the contracted projects under the condition of the total price contract.
