This product is made from modified PP material: its inner wall is smooth, and its outer wall has a unique annular corrugated pattern, with a hollow space between the inner and outer walls. Chemical and corrosion resistance: It resists erosion from acids, alkalis, salts, and various other chemical media. It is an excellent corrosion-resistant material itself and is not corroded by decaying substances in the soil.
Made from high-density polyethylene (HDPE), this special pipe features a smooth inner wall, a corrugated outer wall, and a hollow space between the inner and outer walls. It is mainly used in underground sewage and drainage systems. The socket uses a double-walled structure, expanded online during production. The double-walled structure is relatively rigid, and a flexible connection is achieved using natural rubber. It is easy to install, the connection is reliable and leak-proof, the overall cost is low, and the service life is up to 50 years.
HDPE spiral-wound reinforced structural wall type B pipe, also known as HDPE spiral-wound structural wall pipe, KRALA pipe, HDPE spiral-wound type B pipe, high-density polyethylene spiral-wound pipe, and type B structural wall pipe. It is a new type of flexible pipe material with characteristics such as light weight, high strength, smooth inner wall, corrosion resistance, aging resistance, wear resistance, pressure resistance, strong impact resistance, good flexibility, and hygiene safety. It features high fusion quality, integral connection, good connection quality, 100% leak-proof, long service life, and quick and easy installation.
Steel strip reinforced high-density polyethylene (HDPE) spiral corrugated pipe is a structural wall pipe made of HDPE and steel strip melt-composite. The pipe wall structure consists of three layers: the inner layer is a continuous solid wall inner pipe; the outer layer of the inner pipe is a composite of useful steel strips wound around and folded into an inverted "U" shaped annular corrugated steel strip reinforcement; and the outer layer is a HDPE outer layer composite with the same corrugated shape as the steel strip reinforcement. The novel structure is scientific and reasonable.
