Anti-settlement high-strength PP-HM double-wall corrugated pipe

Category: Drainage and sewage pipe

Description：The anti-subsidence high-strength PP-HM double-wall corrugated pipe is a non-pressure underground drainage and sewage structural wall pipe system, featuring a smooth inner surface and a specially shaped outer surface. This type of pipe system is made from high-strength modified PP-HM resin as the base material, with the addition of special modified functional masterbatch, which enhances the product's impact resistance, rigidity, and weather resistance while ensuring stable product quality. The research team at Guodi Technology collaborates with outstanding domestic equipment manufacturers to optimize the design of the pipe's corrugated structure, making it more rational. Compared to traditional double-wall corrugated pipes, it has a higher rigidity-to-weight ratio and better cost performance; especially in challenging construction environments, such as those with collapsible soil or high backfill foundations, its advantages are even more pronounced under high anti-subsidence requirements, making it a safe and reliable choice for you.

Description

　　Product Introduction

The anti-subsidence high-strength PP-HM double-wall corrugated pipe is a non-pressure underground drainage and sewage structural wall pipe system, featuring a smooth inner surface and a specially shaped outer surface. This type of pipe system uses high-strength modified PP-HM resin as the base material, with the addition of special modified functional masterbatch, which enhances the product's impact resistance, rigidity, and weather resistance while ensuring stable product quality. The research team at Gu Di Technology collaborates with outstanding domestic equipment manufacturers to optimize the design of the pipe's corrugated structure, making it more reasonable. Compared to traditional double-wall corrugated pipes, it has a higher rigidity-to-weight ratio and better cost performance; especially advantageous in harsh construction environments where the geological conditions are collapsible soil or high backfill foundations, and where high anti-subsidence requirements are needed, making it a safe and reliable choice for you.

　　Product Features

1. Made from brand new high-modulus PP material from Nordic Chemical Basel, with a maximum diameter of up to 1.8 meters;

2. Excellent anti-subsidence: When the socket and spigot experience a certain degree of displacement due to foundation changes, the unique 'parallel' bell mouth design can withstand ground movement and resist uneven ground subsidence;

3. High strength: Ring stiffness can reach SN16 level, providing great rigidity to resist external pressure;

4. Convenient and reliable connection: Adopts the latest design of 'high-low double knife' type sealing ring, forming the advantage of 'barbed' edges, eliminating the defects of 'single knife' type, greatly reducing penetration damage;

5. Aging resistance and long lifespan: Can withstand direct sunlight during storage and construction, usable in soil with pH 1.5-1.4, and under temperatures below 30°C, with a service life of up to 100 years;

6. Excellent wear resistance: More conducive to the discharge of rainwater or sewage containing silt;

7. Low lifecycle cost of the product: Less than 50% of similar products;

8. Outstanding chemical stability and corrosion resistance;

9. Environmental impact: Polypropylene is a non-toxic raw material that is harmless to soil and can be fully recycled or repurposed as fuel;

　　Application Fields

Municipal Engineering: Used as drainage and sewage pipes.

Industry: Widely used in chemical, hospital, environmental protection industries for sewage pipes;

Mining Sites: Used for mine ventilation, air supply, and drainage pipes;

Agricultural Land Engineering: Used for irrigation and drainage in farmland, fruit tea gardens, and forest belts; golf courses;

Soccer Field Engineering: Used as drainage pipes for golf courses and soccer fields;

Construction Engineering: Used as rainwater pipes for buildings, underground drainage pipes, sewage pipes, ventilation pipes, etc.;

Road Engineering: Used as drainage pipes for railways and highways.

Highway Communications: Used as protective pipes for communication cables and optical fibers.

Perforated double-wall corrugated pipe: Can be used as drainage pipes for saline-alkali land highways.
