Product Description

Ductile Iron Pipe, K9 Grade, 1400mm: A Superior Pipeline Solution
I. Product Overview
The Ductile Iron Pipe, with a diameter of 1400mm and K9 grade, is a high - quality piping product designed to meet the demanding requirements of various infrastructure projects. The "K9" grade represents a specific wall - thickness classification, indicating a relatively thick wall that endows the pipe with enhanced strength and durability.

II. Key Performance Features
A. High Strength
Tensile Strength
The K9 - grade 1400mm ductile iron pipe exhibits remarkable tensile strength. It can withstand significant pulling forces without deformation or rupture. This is crucial in pipeline systems where the pipe may be subject to external forces during installation or due to ground movement. For instance, in large - scale water supply projects spanning long distances, the pipe needs to maintain its integrity under the stress of being laid across various terrains.
Yield Strength
The high yield strength of this pipe ensures that it can resist permanent deformation even when subjected to high - pressure loads. When the water pressure in a pipeline system increases, the pipe can safely accommodate the pressure changes without yielding, thereby guaranteeing the continuous and stable operation of the water supply or gas transmission network.
B. Excellent Pressure - bearing Capacity
Internal Pressure Resistance
With its robust construction and appropriate wall thickness as defined by the K9 grade, the 1400mm ductile iron pipe can endure high internal pressures. It is capable of withstanding pressures well above the normal operating pressures in most water and gas distribution systems. This feature makes it suitable for use in high - pressure water supply networks, such as those in large industrial complexes or high - rise building water supply systems.
External Load Resistance
The pipe is also designed to resist external loads. Whether it is the weight of the overlying soil in a buried pipeline or the impact from passing vehicles in a road - crossing installation, the K9 - grade 1400mm ductile iron pipe can maintain its structural integrity. This is due to the combination of its high - strength material and the optimized wall - thickness design.
C. Good Corrosion Resistance
Material - based Corrosion Resistance
Ductile iron itself has a certain degree of corrosion resistance. The graphite in the ductile iron matrix is in a spherical form, which improves the material's corrosion resistance compared to other types of cast iron. This inherent property helps to protect the pipe from the corrosive effects of the substances it transports, such as water with varying chemical compositions.
Coating - enhanced Corrosion Resistance
In addition to the material's natural corrosion resistance, the 1400mm K9 - grade ductile iron pipe is often coated with anti - corrosion materials. Common coatings include zinc - based coatings and epoxy coatings. The zinc coating acts as a sacrificial anode, protecting the iron substrate from corrosion. The epoxy coating, on the other hand, provides a physical barrier, preventing the ingress of corrosive substances such as water, oxygen, and chemicals.
D. Smooth Inner Surface
Reduced Friction Loss
The inner surface of the 1400mm K9 - grade ductile iron pipe is smooth, which significantly reduces friction loss. When transporting fluids like water or gas, a smooth inner surface allows for a more efficient flow. This means that less energy is required to pump the fluid through the pipeline, resulting in cost savings for the operators of the water or gas supply systems.
Anti - scaling and Anti - fouling
The smooth inner surface also helps to prevent the formation of scale and fouling. In water supply systems, scale formation can reduce the inner diameter of the pipe over time, increasing flow resistance. The smooth surface of the ductile iron pipe inhibits the adhesion of minerals and other substances that cause scale formation, thus maintaining the long - term performance of the pipeline.
