In the wave of urban development, water conservancy projects, and industrial construction, the safety and durability of pipeline systems have always been a focus of industry attention. Ductile iron pipes, with their superior tensile strength and comprehensive performance, have become the preferred material for various water and gas transmission projects. In this field, DINSEN DI pipes have won widespread market recognition for their robust technical strength and reliable product quality.
Tensile strength is a key indicator for measuring whether a pipeline material can withstand internal pressure and external loads. Ordinary cast iron pipes are brittle and prone to fracture; while EN545 ductile iron pipes, through advanced spheroidizing treatment, have graphite distributed spherically within the iron matrix, greatly improving the material’s toughness and strength. Their tensile strength can reach over 420 MPa, far exceeding that of ordinary cast iron and even approaching the level of steel. This characteristic makes the pipelines exhibit extremely strong adaptability and safety when buried underground and subjected to ground dynamic loads and geological settlement.
Tensile Strength 445.63 MPa
As a leading domestic supplier of ductile iron pipes, DINSEN consistently prioritizes technological innovation to drive product upgrades. DINSEN ductile iron pipes utilize high-purity molten iron, strict control over the addition of spheroidizing agents, and modern centrifugal casting processes to ensure that every pipe possesses a uniform microstructure and stable mechanical properties.
Furthermore, DINSEN pipes excel in socket joint design and internal and external corrosion protection (such as cement mortar lining and zinc coating + asphalt paint external corrosion protection), resulting in superior tensile strength, corrosion resistance, sealing performance, and service life.
Whether for urban water supply networks, fire-fighting water systems, or industrial circulating water and rainwater drainage projects, DINSEN ductile iron pipes, with their high tensile strength and impact resistance, can withstand complex working conditions, significantly reducing the risk of pipe bursts and leaks. For many years, DINSEN products have been successfully applied in infrastructure projects across numerous provinces and cities, becoming a trusted partner for local governments and construction companies.
Choosing DINSEN ductile iron pipes means choosing long-term safety and peace of mind. We firmly believe that superior performance, exemplified by tensile strength, is not only the core competitiveness of our products but also a quality commitment to every user. Let DINSEN join hands with you to build a more robust and durable pipeline network, safeguarding a better life!
