Elbow

1, The prefabricated insulation quality requirements with the straight pipe(CJ/T155-2001). 2, For central heating systems.

The Elbow

1. Product Features:

a) Construction of low cost and easy construction. Without laying the trench can be buried in the ground, not only save investment, but also construction and installation and quick. Because of its long service life, and without significantly reducing overall costs maintenance leaving.

b)Operation and long life. Prefabricated insulation overall good, with good compression, corrosion and water features, such as installation and use according to specifications, operating life up to 30 years.

c) The insulation effect. Polyurethane insulation materials with closed cell high thermal insulation properties, low water absorption. The hot (cold) loss of only 25% of traditional insulation materials, significantly reducing energy operating costs.

d) Enabling regulation of landscaping and urban. Pipe buried in the ground, no heat (cold) pollution will not affect the ground rules of landscaping and design, is building a modern urban, amenity and community and public benefit the environment the best choice.

2. Structure:

    Rigid polyurethane foam insulation jacket consists of three parts: the work of steel pipe, polyurethane thermal insulation and outer casing of high density polyethylene pipe. Insulating layer of polyurethane foam using a proprietary formula made of fluorine-free, meet environmental requirements. After the outer surface of steel shot blasting treatment, both rust, but also to make steel surface area have greatly increased, effectively enhance the insulation between the pipe and pipe friction. High-density polyethylene outer casing tube surface after corona treatment, to the substantial increase in surface area and surface tension to improve the insulation layer of protective tubes and between the shear strength, and effectively remove the oxide layer.

Specify:

1)After several tests and technology research, our company successfully developed the Combination of corona treatment process with an effective step to improve production efficiency.

2) One-step simultaneous production of automatic correction, avoiding the eccentric, uneven pressure, the bubble hole and other defects.
