Water Supply Pipe

The ductile iron material features similar mechanical properties with carbon steel, such as high mechanical strength, good ductility, and the same anti-corrosion performance as cast iron. Therefore, it has gradually become the world’s most safe and reliable pipes in the field of water supply and drainage.
Eastern Steel Manufacturing Co.,Ltd provides ductile iron pipe products ranging from DN80 ～ DN2600mm in accordance with ISO 2531/ISO7186 or EN 545/EN598.

At present, the types of centrifugal ductile iron pipe joint are divided into the following: XT2 St Self-Anchored joint ductile iron pipes suitable for DN80~DN300, SIA Wb、TF Self-Anchored joint ductile iron pipes suitable for DN300~DN1200, Xanchor ® Self-Anchored joint ductile iron pipes suitable for DN1400~DN2000.

Ductile iron water supply pipes are widely used in urban water supply systems due to their high strength, corrosion resistance and good sealing performance. 

Ductile iron water supply pipes mainly include the following types:
‌1. T-type ductile iron pipe

It adopts T-type socket, and the interface seal usually uses rubber ring, which is easy to install and is often used in municipal water supply, drainage and other projects.

2‌. K-type ductile iron pipe

It has good mechanical properties and strong sealing performance, and is suitable for occasions with high requirements for pipeline performance.

3‌. N1-type ductile iron pipe

The interface form is N1 type, which is suitable for specific engineering needs.

‌4. S-type ductile iron pipe

The interface form is S-type, which is suitable for specific application scenarios.

The following are common ductile iron water supply pipe models:

1. K7 ductile iron water supply pipe

The K7 type is a more common model, with standard sizes ranging from DN100 to DN600, suitable for general urban water supply systems. This type of pipe has a high pressure bearing capacity and good corrosion resistance, and can meet most water supply needs.

2. K8 ductile iron water supply pipe

The K8 ductile iron water supply pipe is slightly larger than the K7 type in size, with standard sizes ranging from DN700 to DN1200, suitable for large water supply systems or occasions requiring higher flow. This type of pipe also has go

od corrosion resistance and pressure bearing capacity.

3. K9 ductile iron water supply pipe

The K9 type is the largest ductile iron water supply pipe, with standard sizes starting from DN1400, suitable for extra-large water supply systems or occasions with special needs. Due to its large size, it requires more space and professional technical support for installation.
