Overview
Principles of Construction
Cast iron drain pipe is a high-density steel material pipeline mainly used in drainage systems.
It is widely used in drainage fields such as highways, railway subgrades, subway engineering, waste landfills, tunnels, green belts, sports fields, and slope protection with high water content due to its characteristics of wear resistance, high temperature resistance, long service life, earthquake resistance, sound insulation and noise reduction. It is also used in underground irrigation and drainage systems for agriculture and horticulture. Especially in bridge drainage systems, cast iron drainage pipes play an indispensable role in effectively collecting, diverting, and blocking rainwater, protecting bridge structures from water damage.
Cast iron drainage pipes are usually made of high-strength cast iron materials, which have high compressive, impact, and corrosion resistance, and can withstand long-term loads from bridge traffic, ensuring stable drainage performance even in harsh environments. In addition, its pipe body is smooth and free of sand holes, with a long service life, and the galvanizing process makes the possibility of corrosion extremely small, almost maintenance free for life, low cost, and high cost-effectiveness.

Product advantages
The product advantages of cast iron drain pipes are mainly reflected in high strength, corrosion resistance, good sealing, strong seismic resistance, and high environmental friendliness.
Firstly, the cast iron drain pipe is made of high-strength materials, which have high tensile and compressive strength, and can withstand large pressures and loads, ensuring its long-term stability and reliability.
Secondly, cast iron drain pipes have strong corrosion resistance and can adapt to various complex environments, including corrosive substances such as acid and alkali, effectively extending their service life.
Furthermore, cast iron drain pipes have excellent sealing performance, and their unique connection method ensures a tight connection between pipes, preventing water leakage and ensuring the normal operation of the drainage system.
In addition, cast iron drainage pipes also have excellent seismic performance. The high-density and strong toughness materials make them stable in natural disasters such as earthquakes, reducing secondary disasters caused by pipeline rupture.
Finally, cast iron drain pipes have minimal impact on the environment during production and use, and are easy to recycle and reuse, meeting the green environmental protection requirements of modern society.

The working principle of cast iron drainage pipes is mainly to use the connectivity and gravity of the pipes to achieve drainage function. When there is water flow that needs to be discharged, it will enter the cast iron drain pipe through the inlet. Due to the fact that cast iron drainage pipes are usually installed at locations with a certain slope, water will flow downwards along the pipeline under the action of gravity. The inner wall of cast iron pipes is relatively smooth, with low resistance to water flow, allowing water to pass smoothly and quickly, thereby improving drainage efficiency. |
Product Structure
|
The cast iron drain pipe is mainly composed of cast iron pipe, pipe seat, shock absorber, and fasteners.
Cast iron pipes are the main component of drainage pipes, generally made of ball milled cast iron, which has good corrosion resistance and strength, can withstand large water pressure and external impact, and ensure the long-term stable operation of the drainage system.
The function of the pipe seat is to fix the cast iron pipe, prevent it from moving or overturning, and ensure the stability of the pipeline system.
Shockproof hammer is used to reduce the impact force of water flow on cast iron pipes, avoid damage to the pipe body due to excessive impact force, and thus extend the service life of drainage pipes.
Fasteners are used to connect and fix the components between cast iron pipes and pipe sockets, ensuring the firmness of the pipeline connection.
In addition, the two ends of cast iron drain pipes are usually designed with different interface forms, such as socket type interfaces and flange type interfaces, to meet different connection requirements. The plug-in interface is easy to install and has good sealing performance; The flange interface connection is firm and suitable for drainage systems that can withstand high pressure. |
Applications
|
Cast iron drainage pipes are widely used in various fields such as construction, transportation, water conservancy, municipal engineering, and industry.
In the field of architecture, cast iron drainage pipes are an important component of roof drainage systems, which can effectively guide and discharge rainwater from the roof, preventing rainwater accumulation from causing damage to the roof structure.
In the field of transportation, cast iron drainage pipes are mainly used in the drainage systems of railway bridges, guardrail supports on both sides of highways, as well as drainage projects in tunnels and underground passages, to ensure the safety and stability of transportation facilities.
In water conservancy and municipal construction, cast iron drainage pipes are widely used in the drainage systems of hydraulic structures such as reservoirs, embankments, and channels, as well as in the rainwater collection systems of roads, bridges, squares, and parks, effectively removing excess water bodies, maintaining system balance, and preventing urban waterlogging.
In the industrial field, cast iron drain pipes play an important role in industries such as chemical, metallurgical, and power. They are used to discharge corrosive media or treat drainage problems in high temperature and high pressure environments. With their excellent corrosion resistance and high temperature resistance, they have become the preferred choice for these special working conditions.
In addition, cast iron drainage pipes are also used in underground irrigation and drainage systems for agriculture and horticulture, as well as soil and water conservation projects for hillside development |
