QT450-10 matrix with a tensile strength of >=450 MPa; offers impact and settlement resistance, combining the corrosion resistance of cast iron with the toughness of steel.
Available in socket-and-spigot or double-flange configurations; utilizes EPDM rubber gaskets for flexible sealing that accommodates slight deflection, ensuring quick installation.
Smooth internal walls (C≈130); head loss during a 45℃ turn is only 50%–60% of that for a 90℃ elbow.

|
|
Great elongation and high pressure resistance, suitable for high-pressure water supply trunk pipelines. |
Almost no plasticity with low pressure bearing capacity, only applicable for low-pressure drainage pipelines. |
|
|
Excellent fatigue resistance. Withstands frequent pressure fluctuations and water hammer impact, extending service life. |
Prone to crack expansion under alternating stress, poor resistance to water hammer and cyclic load. |
|
|
Optimized wall thickness under equal pressure rating, lighter weight, lower transportation and construction costs. |
Requires thicker wall to compensate brittleness, resulting in heavier weight and higher onsite cost. |
|
|
Complete standard system with T-type / K-type sockets and flange connections; high gasket interchangeability. |
Mostly outdated non-standard products, difficult part replacement and poor project compatibility. |
|
Long-term Operation Cost |
Low failure rate, greatly reduces maintenance, excavation and water outage repair costs. |
Frequent breakage requires full-section excavation and replacement, causing high maintenance expenses. |
