What is the difference between ordinary rubber rings and anti-slip rubber rings?
In the sealing system of ductile iron pipes, the “soul” of the T-shaped socket joint lies in the tiny rubber ring. Though inconspicuous, it directly impacts the sealing reliability, operational safety, and service life of the entire piping system. The choice of “anti-slip rubber...Read more -
What is the Difference between Cast Iron Pipe and Ductile Iron Pipe?
In building water supply and drainage, and in municipal engineering, cast iron pipes are highly favored for their durability, corrosion resistance, and noise reduction. However, when faced with the two European standards, EN545 and EN877, many engineers, procurement personnel, and designers may b...Read more -
Type Test of Ductile Iron Pipe Flange Joints
To verify the strength and tightness of flange joints under service conditions, they must undergo type testing. The flanged pipe must exhibit no noticeable leakage under the combined effects of internal pressure and the corresponding bending moment. The test conditions are: The internal pressure ...Read more -
Common Joint Types for Ductile Iron Pipes
For any pipe connection, the joint type is the core, directly determining the system’s sealing, stability, and construction efficiency. For ductile iron pipes, the three most commonly used joint types are the T-shaped socket joint, the flange joint, and the self-anchor joint, each playing a...Read more -
Verification of Leak-Tightness in Ductile Iron Pipe Joints According to EN545
Ductile iron pipe has become one of the preferred materials for water pipeline systems due to its high strength, toughness, and excellent corrosion resistance. The reliability of a pipeline system depends not only on the pipe itself, but more critically on its connection points—the joints. The EN...Read more -
EN545 Flexible Joint Angle Requirements
In the design and manufacture of flexible joints, the allowable deflection angle should be no less than: DN40~DN300: 3.5° DN350~DN600: 2.5° DN700~DN2000: 1.5° All joints must be designed to allow for perfect axial movement and allow for extraction. The flexible joint technology for ductile iron ...Read more -
EN545 Joint Performance Requirements
Type testing is a series of comprehensive and rigorous tests conducted on one or a few representative samples to verify whether the product design fully meets the requirements of standards and technical specifications. According to EN545 standard requirements: At least one specification in each ...Read more -
What grade of ductile iron pipe is most suitable for your project?
According to the EN545 standard, the pressure testing ductile iron pipe shall be carried out on all fittings before the application of their external and internal coatings, except for the metallic zinc coating of pipes which may be applied before the test, No leakage or sweating should be detect...Read more -
How to Correctly Identify EN545 Ductile Iron Pipes and Fittings
According to EN545, the markings on ductile iron pipes and fittings should be clear, durable and include the following: DI pipe marking tape Pipe marking labels DS: Manufacturer’s Name or Trademark ISO2531: Implementation Standard Number (e.g., EN545) DN1000: Nominal Diameter C25: Pres...Read more -
Coating Options for EN545 Fittings
In the field of ductile iron pipe fittings, asphalt coating, polyurethane/polyethylene (PU/PE) coating and fusion bonded epoxy powder (FBE) coating are three representative anti-corrosion technologies, which are suitable for different environments and working conditions. 1. Zinc-rich primer, asph...Read more -
EN545: Internal Corrosion Protection of Ductile Iron Pipes
In modern urban life, the sanitation and environmental protection requirements of urban water supply must be taken into consideration. To prevent rust from contaminating tap water and to protect the pipes from corrosion from within, the inner wall of the pipes must be coated with an internal coat...Read more -
EN545 Ductile Iron Pipe Coating
Before spraying, the surface of ductile iron pipes must be dry and free of rust, attached particles, oil, and other foreign matter. Unlike SML pipes, ductile iron pipes do not require sandblasting pretreatment due to the inherent properties of the material. Ductile iron pipes, through a spheroidi...Read more
