HDPE Structural Wall Winding Pipe Type B (Krah Pipe)

Description Specifications Scope of Application FAQ Download

Description

Krah pipe is a high-performance plastic pipe made of high-density polyethylene (HDPE) as raw material and manufactured through hot winding molding process. Its unique structural design and production process combine excellent characteristics such as high strength, corrosion resistance, and long life, making it an ideal pipe material choice for modern urban construction and industrial development.

Specifications

Product characteristics

Adopting spiral winding technology, the pipe wall has a hollow structure, and a PP corrugated liner tube is added in the middle of the wave peak, which has significantly higher strength and stability than double wall corrugated pipes.

Smooth inner and outer walls, low fluid resistance.

The ring stiffness can reach SN16, and the compressive performance is excellent.

Flexible pipes that can withstand a certain degree of deformation.

Scope of Application

1. Municipal drainage: Rainwater and sewage pipe network, anti-settlement and non-leakage.

2. Industrial pollution discharge: Resistant to chemical corrosion, safe and reliable.

3. Sponge City: Permeable drainage helps with rainwater recycling.

FAQ

Q1: What are the recommended fusion welding temperatures for PE and PP-R pipes?

What are the recommended fusion welding temperatures for PE and PP-R pipes?
Q2: What are the maximum service temperatures and pressures for PE and PP-R pipes in water supply systems?

"PE pipes have a maximum service temperature of 40°C and a pressure rating of 1.6 MPa. PP-R pipes have a maximum service temperature of 70°C and a pressure rating of 1.0 MPa"
Q3: What are the available pressure ratings for PE pipes, and which are the most commonly used?

"PE pipes are available in eight pressure ratings, ranging from PN0.4 to PN2.0. The most commonly used ratings are: PN0.6, PN0.8, PN1.0, PN1.25, and PN1.6."
Q4: What are the standard pipe lengths for PE pipes, and how can the length be customized?

"PE pipes are supplied in both coils and straight lengths. Coiled pipes are typically supplied in 100-meter rolls. Straight pipes are generally 6 meters per length. Customized lengths are also available upon request, such as 9 meters or 12 meters per coil, depending on customer requirements."
Q5: What types of PE fittings are available, and how should they be selected?

"There are three main types of PE fittings: Socket fusion fittings (recommended for sizes DN20 to DN110) Butt fusion fittings (commonly used for sizes above DN110) Electrofusion fittings, which are commonly used in standard water supply systems and are typically applied in maintenance and repair scenarios."
