Product introduction

Basalt fiber winding pipe is a new type of high-tech composite pipe made of basalt fiber as the main material, which has the advantages of excellent corrosion resistance, long service life; good hydraulic performance, large conveying flow; high strength, safe/secure and reliable; light weight, easy installation and transportation; short construction period and low comprehensive investment; green environment/protection and so on. It can be widely used in urban rainwater and sewage network, farmland irrigation, urban water diversion and transmission, municipal water supply network, water conservancy and hydropower, petrochemical and other fields; and in many aspects, it shows its superiority compared with spiral steel pipe, ductile iron pipe, steel cylinder concrete pipe (referred to as PCCP pipe), PE pipe.

Pipe wall structure

:: Pipe wall structure from the inside to the outside: lining layer, structural layer, external protective layer. The lining layer acts as an anticorrosive and impermeable layer, the structural layer acts as the strength and rigidity of the pipe, and the outer protective layer acts as an anti-aging, anti-corrosive, and sunlight-resistant layer, which is the best expression of the designability of the composite material.

Features and Advantages

● Light weight and high strength, easy transportation

Basalt fiber water supply and drainage pipe is light weight and high strength, its specific gravity is 1.7-1.9, so it is easy to transport and the transportation cost is low.

● Excellent corrosion resistance, long service life

Basalt fiber water supply and drainage pipe has good corrosion resistance to many chemical fluids such as acid, alkali and salt.

● Excellent hydraulic properties and high conveying capacity

Basalt fiber water supply and drainage pipe has smooth inner wall, and its roughness coefficient is 0.0084, therefore, it can choose smaller pipe diameter or smaller power transfer pump, so as to reduce the initial investment in pipeline project, save electricity and reduce the operation cost.

● Good heat and frost resistance

The temperature range of basalt fiber water supply and drainage pipe is generally between -40℃ and 70℃; the coefficient of thermal expansion of basalt fiber water supply and drainage pipe is small.

● Convenient and quick installation

Basalt fiber water supply and drainage pipe is connected by double-seal ring socket connection, flange connection, butt bonding, etc. Elbow tee can be made on site. Pipe section length is generally 12m, less joints, mainly using double “O” type rubber ring socket connection, fast installation.

● Easy maintenance and low cost

Basalt fiber water supply and drainage pipes do not need antirust, anti-corrosion, insulation and other treatments, no need for cathodic protection of buried pipes, can save more than 70% of the project maintenance costs.

● Flexible design, strong adaptability

The pressure level of basalt fiber water supply and drainage pipe is 0.25-4.0 Mpa, which can be flexibly and conveniently applied to a wide range according to various requirements of users.

● Good comprehensive benefit of project

Basalt fiber water supply and drainage pipe has excellent performance characteristics, and its comprehensive benefit is superior/better, especially the larger the pipe diameter, the lower the cost.
