Description

Technical Field

[0001] The utility model relates to the technical field of PPR pipes, in particular to a corrosion-resistant and non-scaling PPR pipe. Background Art

[0002] Compared with traditional cast iron pipes, galvanized steel pipes, cement pipes and other pipes, PPR pipes have the advantages of energy saving and material saving, environmental protection, light weight and high strength, corrosion resistance, smooth inner wall and no scaling, easy construction and maintenance, and long service life. They are widely used in building water supply and drainage, urban and rural water supply and drainage, city gas, electricity and optical cable sheathing, industrial fluid transportation, agricultural irrigation and other construction, municipal, industrial and agricultural fields.

[0003] Most of the existing PPR pipes do not have the noise reduction function when in use, resulting in noise when liquid flows inside the PPR pipe, thus causing noise pollution. Although sound insulation cotton is added to the outside of the existing PPR pipe, the sound insulation effect is still poor. Therefore, we proposed a corrosion-resistant and non-scaling PPR pipe. Utility Model Content

[0004] 1. Technical issues to be solved

[0005] In view of the deficiencies in the prior art, the utility model provides a corrosion-resistant and non-scaling PPR pipe, which has the advantages of being equipped with a soundproof cavity. When liquid flows in the pipe body, the sound of the liquid flow can be reduced under the action of the soundproof cavity, thereby reducing the propagation of sound, and the flowing liquid can be buffered under the action of the noise reduction strip, thereby reducing the excessive sound of the liquid flow, thereby increasing the noise reduction treatment of the sound, and at the same time, under the action of the corrosion-resistant layer, the corrosion resistance of the device is increased, etc., which solves the problem that noise is generated when liquid flows inside the PPR pipe, thereby causing noise pollution. Although sound insulation cotton is added to the outside of the existing PPR pipe, the sound insulation effect is still poor.

Stainless steel is a universal material. It has a series of excellent properties such as corrosion resistance, high strength, high temperature resistance, and the like, and its surface is smooth and easy to clean. Under normal circumstances, scale will not form on the surface of stainless steel.
